Answer:
Step-by-step explanation:
a) While line crosses y axis, x = 0
Plugin x = 0 in the equation
y - 4*0 = 1
y = 1
(0 , 1)
b) line passes through the point (0, -3)
y = 2x + c
-3 = 2*0 + c
-3 = c
Equation: y = 2x - 3
y=2x -3 passes through (k,10)
10 = 2*k - 3
10 = 2k - 3
10 + 3 = 2k
13 = 2k
13/2 = k
k = 6.5
Choose the diagram that shows the graph of the inequality
Answer: C
Step-by-step explanation:
First, simplify the inequality:
x - 2 ≤ 1 add 2 to both sides
x ≤ 3
If x is less than or equal to 3, the graph should be decreasing, starting from 3. (C)
Graph of inequality x - 2 ≤ 1 is represented by diagram C.
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given inequality
x - 2 ≤ 1
Adding 2 on both sides
x ≤ 3
For x - 2 ≤ 1, value of x should be less or equal to 3
Hence, Diagram C shows the graph of inequality x - 2 ≤ 1.

Between which two consecutive whole numbers does the square root of 91 lie?
Answer:
the square root of 91 lies between 9 and 10
The value of the square root of 91 is 9.54 thus the two consecutive whole numbers 9.54 lie in between will be 9 and 10.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a widespread number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
As per the given square roots,√91
The value of √91 is 9.539
The whole number less than 9.539 is 9 and greater than 9.539 is 10.
Thus, 9 < 9.539 < 10
Hence "The value of the square root of 91 is 9.54 thus the two consecutive whole numbers 9.54 lie in between will be 9 and 10".

What happens to the value of the expression \dfrac{3y}{2y} 2y 3y start fraction, 3, y, divided by, 2, y, end fraction as yyy increases?
Answer:
The value of expression remains the same
Step-by-step explanation:
Let the given function be f(y), where
[tex]f(y) = \frac{3y}{2y}[/tex]
Lets put different values of y to finds its effect on the function
f(y) = 3y/2y
Let y = 1

Solve for y. Please show work.
5y^2 - 2 = 3y
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y^2 - 2 = 3y
5y^2 - 3y - 2 = 0
(5y + 2)(y - 1)
5y + 2 = 0 or y - 1 = 0
5y = -2 or y = 1
y = -2/5 or y = 1
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y²-2 = 3y
Add -3y on both sides
5y²- 3y -2 = 0
Factorize.
(5y + 2)(y-1) = 0
(5y+2) = 0
Subtract 2 on both sides.
5y = -2
Divide 5 into both sides.
y = -2/5
(y - 1) = 0
Add 1 on both sides.
y = 1

Find the number of 4-digit numbers that contain at least three even digits.
Answer:
2625
Step-by-step explanation:
First let's see all the possible combinations.
(Even=E, Odd= O)
1) EEEO
2) EEOE
3) EOEE
4) OEEE
5) EEEE
Now let's see what E and O possibly could be
E = 0, 2, 4, 5, 6 and 8 (5)
O = 1, 3, 5, 7, 9 (5)
Now we are just simply gonna multiply
1) EEEO = 4*5*5*5
2) EEOE = 4*5*5*5
3) EOEE = 4*5*5*5
4) OEEE = 5*5*5*5
5) EEEE = 4*5*5*5
The even contains a 0, so you can't put 0 in, so (5-1=4), there are only 4 digits for the even.
500 times 4 = 2000
5⁴ = 625
2000+625= 2625

Plz help. I’m trying but I can’t. Figure this one out. Mainly because the equations aren’t lined up accordingly with the variables
Answer:
x = 2
y = 1
z = 3
Step-by-step explanation:
Okay, we know y=z-x.
Let's plug in that y-value into the first equation: x + 2 (z - x) -z =1
Simplify that down to x +2z -2x -z = 1
Equation 1 becomes -x + z = 1
Let's plug it into equation 3 and solve to get: 2x - (z - x) +3z = 12
Equation 3 becomes 3x + 2z = 12
Now let's use system of equations for those two equations we just found
3x + 2z = 12
-2x + 2z = 2 ------> multiplied this by 2 to simplify
subtract, and you 5x = 10, x = 2
Use x = 2 and solve for the other variables using the same method (try this on your own!) to get y = 1 and z = 3

plz help find the equation of the circle
Answer:
[tex](x-2)^2+(y+4)^2=34[/tex]
Step-by-step explanation:
The standard form for the equation of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex], where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius. Since you already know the coordinates of the center of the circle, all you need to do is find the radius. Using the distance formula:
[tex]r=\sqrt{(7-2)^2+(-1-(-4))^2}=\sqrt{5^2+3^2}=\sqrt{25+9}=\sqrt{34}[/tex]
The equation of the circle is therefore:
[tex](x-2)^2+(y+4)^2=34[/tex]

A sporting goods store receives a shipment of 124 golf bags. The shipment includes two types of bags, full-size and collapsible. The full-size bags cost $38.50 each. The collapsible bags cost $22.50 each. The bill for the shipment was $3430. How much of each type of golf bag should be in the shipment? Show all work and verify your answer (prove that your answer is correct)
The sporting goods store receives the shipment of 124 golf bags in total.
Let us assume that the number of full-sized bags = X
Then the number of collapsible golf bags = 124 - X
Cost of each full sized bags = $38.50
Cost of each collapsible bags = $22.50
Total cost of the 124 bags received by the sporting goods store = $3430
Then
(38.50)X + (124 - X)22.50 = 3430
(38.50X - 22.50X) + 2790 = 3430
16X = 3430 - 2790
16X = 640
X = 640/16
= 40
So the number of full-sized golf bags received = 40
Then the number of collapsible golf bags received = 124 - 40
= 84

The sum of two numbers is 48. The small number is 6 less than the big number. What is the small number?
Answer:
x=6
Step-by-step explanation:
x+y=48
x=y-6
substitute "y-6" instead of x
x+y=48
(y+6)+y=48
y+y is equal to y
6+y=48
-6 -6
y= 42
x= 48-y
x=48-42
x=6
I hope this helped
Answer:
21Step-by-step explanation:
x - the small number
x+6 - the big number
x + x + 6 = 48
2x + 6 = 48
- 6 - 6
2x = 42
÷2 ÷2
x = 21
Verifying:
x+6 = 21 + 6 = 27
21 + 27 = 48
You are given the function C(x)=−4x2+4x+3 Find C(−1). Provide your answer below: C(−1)=
Hey there! :)
Answer:
C(-1) = -5.
Step-by-step explanation:
C(x) = -4x² + 4x + 3
Plug in -1 for x to solve for C(-1):
C(-1) = -4(-1)² + 4(-1) + 3
Simplify:
C(-1) = -4 + (-4) + 3
C(-1) = -5
Answer:
C(-1)= -5
Step-by-step explanation:
This question asks us to find C(-1). We know what C(x) is, it is:
[tex]C(x)=-4x^{2} +4x+3[/tex]
Therefore, we must substitute -1 in for every x to find C(-1).
[tex]C(-1)=-4(-1)^{2} +4(-1)+3[/tex]
Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
First, evaluate the exponent.
-1^2=-1*-1=1
[tex]C(-1)=-4(1) +4(-1)+3[/tex]
Next, multiply -4 and 1.
[tex]C(-1)=-4+4(-1)+3[/tex]
Multiply 4 and -1 again.
[tex]C(-1)=-4+ -4 + 3[/tex]
Add the numbers together.
[tex]C(-1)=-8+3[/tex]
[tex]C(-1)=-5[/tex]
solve the equation (x-2)^2/3=9
Answer:
x = 2±3sqrt(3)
Step-by-step explanation:
(x-2)^2/3=9
Multiply each side by 3
(x-2)^2/3 *3=9*3
(x-2)^2=27
Take the square root of each side
sqrt( (x-2)^2)=±sqrt(27)
x-2 = ±3sqrt(3)
Add 2 to each side
x = 2±3sqrt(3)
Match each of the following equations according to there slope and y intercept.
Answer:
using the equation of the line y = mx + b
m= slope
b = y intercept
y= - 1.5x - 4 m = -1.5 b = -4
y = -3x + 4 m = -3 b = 4
y = 3x m = 3 b = 0
y = 1.5x - 7 m = 1.5 b = -7
y = 7 m = 0 b = 7
Hope this helps.
Answer:
y=3x goes with m=3, b=0
y=7 goes with m=0, b=7
y=-3x+4 goes with m=-3, b=4
y=1.5x-7 goes with m=1.5, b=-7
y=-1.5x-4 goes with m=-1.5, b=-4
Step-by-step explanation:
The b represents the y- intercept in a graph (where the line crosses the y axis). The m represents the slope of the line. You can find the slope by taking the rise of the graph and dividing it by the run (rise/run). If you get the numbers in the equation form y=mx+b, then you just take the information they give you out of the equation.

In the interval 0 degrees < x < 360 degrees, find the values of x for which cos x = 0.7252. Give your answers to the nearest degree.
Answer:
115° and 245°
Step-by-step explanation:
Given
cos x = - 0.4226
Since cos x < 0 then x is an angle in the second / third quadrants, thus
x = (0.4226) = 65° ← related acute angle , thus
x = 180° - 65° = 115° ← angle in second quadrant
x = 180° + 65° = 245° ← angle in third quadrant
Answer:
[tex]x=\{44\º, 317\º\}[/tex]
Step-by-step explanation:
The interval given is [tex](0, 360\º) \text{ or } (0, 2\pi)[/tex]
In exercises of this kind I usually use
[tex]\cos \left(x\right)=a\quad \Rightarrow \quad \:x=\arccos \left(a\right)+360\º n, n \in \mathbb{Z}[/tex]
[tex]\quad \:x=\arccos \left( 0.7252\right)+360\º n, n \in \mathbb{Z}[/tex]
And [tex]\arccos \left( 0.7252\right) \approx 43.5^{\circ \:}[/tex]
But once we have the solution for cos in two different quadrants, I mean, Quadrant I and Quadrant IV angle.
To the nearest degree, we have
[tex]x=\{44\º, 317\º\}[/tex]
