Graph of two intersecting lines. One line f of x is solid and goes through the points 0, 4, and 4, 0 and is shaded above the line. The other line g of x is solid, and goes through the points 0, negative 1 and 2, 5 and is shaded in below the line. The graph represents which system of inequalities? y ≤ −3x − 1 y ≤ −x − 4 y ≥ −3x + 1 y ≤ −x − 4 y ≤ 3x − 1 y ≤ −x + 4 y ≤ 3x − 1 y ≥ −x + 4
Answer:
(D)y ≤ 3x − 1 y ≥ −x + 4
Step-by-step explanation:
The line f(x) is solid and goes through the points (0, 4) and (4, 0) and is shaded above the line.
The line that satisfies the point (0,4) and (4,0) is y=-x+4
Since it is shaded above the line, we have the inequality sign ≥.
Therefore, one of the lines is y≥-x+4
In the equation of the line y=3x-1
When x=0, y=3(0)-1=-1
When x=2, y=3(2)-1=5
Since it is shaded below the line, we have the inequality sign ≤ .
Therefore, the other line is y≤3x-1.
The correct option is D.
In this exercise we want to mark the correct alternative that corresponds:
The correct option is D.
The line f(x) is solid and goes through the points (0, 4) and (4, 0) and is shaded above the line. The line that satisfies the point (0,4) and (4,0) is:
[tex]y=-x+4[/tex]
Since it is shaded above the line, we have the inequality sign ≥. Therefore, one of the lines is :
[tex]y\geq -x+4[/tex]
In the equation of the line:
[tex]y=3x-1[/tex]
When: [tex]x=0, y=3(0)-1=-1[/tex]
When: [tex]x=2, y=3(2)-1=5[/tex]
Since it is shaded below the line, we have the inequality sign ≤ . Therefore, the other line is:
[tex]y\leq 3x-1.[/tex]
The correct option is D.

The transformation was a 180° rotation about the origin. The transformation was a 270° rotation about the origin. The transformation was a 360° rotation about the origin.
Answer: Transformation is the process of moving a point in a graph to another point. The new point formed is the image of the old point. When an object is transformed each point of the object is moved to another point. There are three types of transformation: Reflection, Rotation, Translation and dilation.
If a point O(x, y) is rotated 90° rotation about the origin., the new point is at O'(-y, x). That is the x coordinates becomes negative of the y coordinate and the y coordinate becomes the x coordinate.
The vertices of the triangles are shown. A (–1, 1) B (1, 1) C (1, 4), If a transformation of 90° rotation about the origin is done, the new points are A' (–1, –1) B' (–1, 1) C' (–4, 1)

Anita plans to cover a solid cone with construction paper for a science project. The cone has a diameter of 11 inches and
a slant height of 28.5 inches. How many square inches of paper will she need to cover the entire cone?
492.20 in.
587.18 in.
982.82 in.
984.39 in.
Answer:
587.18 square inches
Step-by-step explanation:
We would find the Total surface area of the cone
Diameter of the cone = 11 inches
Radius = Diameter ÷ 2 = 11 / 2 = 5.5 inches
Slant height ( l ) = 28.5 inches
Let's take π = 3.14
Total Surface Area of a cone = πrl + πr²
= πr(l + r)
= 3.14 × 5.5( 28.5 + 5.5)
= π × 5.5(34)
= 587.18 square inches
There the square inches of paper will she need to cover the entire cone is 587.18 square inches

Step-by-step explanation:
==>Given:
Triangle with sides, 16, 30, and x, and a measure of an angle corresponding to x = 30°
==>Required:
Value of x to the nearest tenth
==>Solution:
Using the Cosine rule: c² = a² + b² - 2abcos(C)
Let c = x,
a = 16
b = 30
C = 30°
Thus,
c² = 16² + 30² - 2*16*30*cos 30°
c² = 256 + 900 - 960 * 0.8660
c² = 1,156 - 831.36
c² = 324.64
c = √324.64
c = 18.017769

one term of an arithmetic sequence is a17=82 and d=-6. write a rule for the nth term of the sequence. then find a10
Answer:
[tex]a_{10}=124[/tex]
Step-by-step explanation:
In an arithmetic sequence, we are given that:
[tex]a_{17}=82\\d=-6[/tex]
The nth term of an arithmetic sequence, [tex]a_n=a+(n-1)d[/tex]
When n=17, [tex]a_{17}=82,d=-6[/tex], we have:
[tex]a_{17}=a+(17-1)(-6)[/tex]
82=a+(16)(-6)
82=a-96
a=82+96
a=178
Therefore, the 10th term of the sequence
[tex]a_{10}=178+(10-1)(-6)\\=178+9(-6)\\=178-54\\a_{10}=124[/tex]

Answer:
The submarine is 307.8 yards below sea level.
Step-by-step explanation:
Since the 500 yards are the hypotenuse of the right angle triangle, the acute angle opposite the side of the triangle we need to find is known ([tex]38^o[/tex]), we can use the sine function to solve the problem:
[tex]sin(\theta)=\frac{opposite}{hypotenuse} \\sin(38^o)=\frac{x}{500} \\500\,*\,sin(38^o)=x\\x = 307.8307\,\,yards[/tex]
which rounded to the nearest tenth is : 307.8 yards
Emma buys a camping van for £23500 plus vat at 20% she pays deposit then pays the rest in of the cost in 18 equal payments of £940 each month find the ratio of the deposit Emma pays to total of the 18 equal payments give your answer in the simplest part
Answer:
The ratio is 2:3
Step-by-step explanation:
The first thing we need to get here is how much was paid for the Van in total.
That would be;
23,500 + 20% of 23,500
= 23,500 + (20/100 * 23,500)
= 23,500 + (23500/5)
= 23,500 + 4,700 = £28,200
She pays a deposit, which of course wasn’t stated in the question.
But we know she pays the rest in 18 equal payments at £940 each.
The total amount she paid asides the deposit would be :
28,200 -(940 * 18) = 28,200 - 16,920 = £11,280
So what this means is that she paid a deposit of £11,280 and a cumulative installment payment of £16,920
So now, we want to find the ratio of the deposit to the 18 equal parts payment.
Mathematically, that would be;
11,280 : 16,920
= 1128 : 1692
Divide both by 1128
= 1: 1.5
= 1: 3/2
which is same as 2:3
The ratio of the deposit Emma pays to a total of the 18 equal payments is 2/3 and this can be determined by finding the deposit amount and total amount paid for the Van.
Given :
Emma buys a camping van for £23500 plus vat at 20% she pays the deposit then pays the rest of the cost in 18 equal payments of £940 each month.
The total amount paid for the Van is:
[tex]= 23500 + \dfrac{20}{100}\times 23500[/tex]
= 23500 + 4700
= £28200
The total deposit amount is given by:
[tex]= 28200-18(940)[/tex]
= 28200 - 16920
= £11280
So, the ratio of the Emma pays to a total of the 18 equal payments is:
[tex]\dfrac{11280}{16920}=\dfrac{1128}{1692}[/tex]
Further, simplify the above ratio.
[tex]=\dfrac{2}{3}[/tex]
Therefore, the ratio of the deposit Emma pays to a total of the 18 equal payments is 2/3.

Step-by-step explanation:
a^2 +7a + 10 = a(a+2) +5(a+2) = (a+5)(a+2)

The defect length of a corrosion defect in a pressurized steel pipe is normally distributed with mean value 30 mm and standard deviation 7.8 mm [suggested in the article "Reliability Evaluation of Corroding Pipelines Considering Multiple Failure Modes and Time-Dependent Internal Pressure" (J. of Infrastructure Systems, 2011: 216–224)].
What values separate the largest 80% from the smallest 20% of the defect length distribution.
Answer:
[tex]z=-0.842<\frac{a-30}{7.8}[/tex]
And if we solve for a we got
[tex]a=30 -0.842*7.8=23.432[/tex]
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.
Step-by-step explanation:
Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:
[tex]X \sim N(30,7.8)[/tex]
Where [tex]\mu=30[/tex] and [tex]\sigma=7.8[/tex]
For this part we want to find a value a, such that we satisfy this condition:
[tex]P(X>a)=0.80[/tex] (a)
[tex]P(X<a)=0.20[/tex] (b)
As we can see on the figure attached the z value that satisfy the condition with 0.20 of the area on the left and 0.80 of the area on the right it's z=-0.842
If we use condition (b) from previous we have this:
[tex]P(X<a)=P(\frac{X-\mu}{\sigma}<\frac{a-\mu}{\sigma})=0.20[/tex]
[tex]P(z<\frac{a-\mu}{\sigma})=0.20[/tex]
But we know which value of z satisfy the previous equation so then we can do this:
[tex]z=-0.842<\frac{a-30}{7.8}[/tex]
And if we solve for a we got
[tex]a=30 -0.842*7.8=23.432[/tex]
So the value of height that separates the bottom 20% of data from the top 80% is 23.432.

Step-by-step explanation:
the x-intercepts represent that the profit is $0
maximum value represents the highest profit which is $270
increasing intervals: (0, 4)
decreasing intervals: (4, 8)
in order to find the average rate of change, find the x and y coordinates for when x = 1 and x =4. The coordinates are (1, 120) and (4, 270). The average rate of change is basically the slope, which is (270-120)/(4-1) = 160/3= approximately 53.3333. The rate represents the change in profit in $ over the increase of cost of erasers.
As you can see, this a parabola, which consists of going up and down. The constraints of the domain represent that 4 is the best price for eraser because it yields the highest profit. The domain (x values) that are above and below 4 do not yield the best profit.
Polygon ABCD is rotated 90 degrees counter loll about the origin to create polygon A' B' C' D'. Match set of coordinates to vertices of polygon A' B' C' D'
Answer:
A (3, 1)
B (2, 2)
C (1, 2)
D (1, 1)
Step-by-step explanation:
When a point is rotated 90° (90 degrees) counterclockwise about its origin, the coordinate B (x, y) transforms into B' (-y, x).
A′ (-1, 3) B′ (-2, 2) C′ (-2, 1) D′ (-1, 1)
Using the formula above B (x, y) ⇒ B' (-y, x), we have the coordinates for the polygon as:
A′ (-1, 3) ⇒ A (3, 1)
B′ (-2, 2) ⇒ B (2, 2)
C′ (-2, 1) ⇒ C (1, 2)
D′ (-1, 1) ⇒ D (1, 1)
∴ coordinates of the original polygon is given by the vertices:
A (3, 1), B (2, 2), C (1, 2), D (1, 1)
This is the formula for the volume of a right square pyramid, where a is the side length of the base and h is the height: . Which equation correctly rewrites the formula to solve for h?
Answer:
C. h=3V/a^2 is the correct answer
Step-by-step explanation:
Given:
V=1/3a^2h
It can be rewritten as
V=1/3 *( a^2) * h
Divide both sides by (1/3)*h
V / (1/3*h) = (1/3)* (a^2) * h / (1/3)*h
V÷1/3*h = a^2
V÷3/1*h=a^2
3V/h=a^2
Multiply both sides by h
3V/h*h=h*a^2
3V=h*a^2
h=3V/a^2
C. h=3V/a^2 is the correct answer

Solve the systems by the addition method 2x + y = - 1x - 2y = - 4
Answer:
x = -6/5
y =7/5
Step-by-step explanation:
2x + y = - 1
x - 2y = - 4
Multiply the first equation by 2 so we can eliminate y
2(2x + y = - 1)
4x + 2y = -2
Add this to the second equation
4x + 2y = -2
x - 2y = - 4
---------------------
5x + 0y = -6
Divide by 5
5x/5 = -6/5
x = -6/5
Multiply the second equation by -2 so we can eliminate x
-2(x - 2y = - 4)
-2x+4y = 8
Add this to the first equation
2x + y = - 1
-2x+4y = 8
---------------------
0x + 5y = 7
Divide by 5
5y/5 = 7/5
y =7/5
