Write the inequality shown by the graph
Answer:
The answer should be m < -2.5
Step-by-step explanation:
I was taught this before and my teacher always said if its a open circle then its > or < if its a closed circle then it should have the line under it, and the line is going down so it would be Less than sign
can somebody help me please !
both triangles are isosceles
done!
which statement is true about these functions?
1.The graph and the equation have the same slope.
2.The graph has a greater slope.
3.The equation has a greater slope.
4.none of the above.
Answer:
Option (2)
Step-by-step explanation:
1). Equation of the line given in the question is,
[tex]y=\frac{1}{2}x+5[/tex]
Slope of the line = [tex]\frac{1}{2}[/tex]
Slope of the line given in the graph = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{3}{4}[/tex]
But [tex]\frac{1}{2}\neq \frac{3}{4}[/tex]
Therefore, slopes of the line and the line given in the graph are not equal.
Option (1) is incorrect
2). Since, [tex]\frac{3}{4}> \frac{1}{2}[/tex]
Therefore, Option (2) is correct.
3). Since, graph has a greater slope, option (3) is incorrect.
Option (2) is the correct statement.

A line passes through the points (2,4) and (5,6).
Select Yes or No to tell whether each equation describes this line.
y−6=3/2(x+5) Yes No
y−4=2/3(x−2) Yes No
y−4=3/2(x+2) Yes No
y−6=2/3(x−5) Yes No
Answers:
NoYesNoYes============================================================
Explanation:
Let's use the slope formula to get
m = (y2-y1)/(x2-x1)
m = (6-4)/(5-2)
m = 2/3
The slope of the line is 2/3.
We can see that the responses for choices 1 and 3 are "no" because they involve a slope of 3/2.
-------------
Recall that y-y1 = m(x-x1) represents the point slope form. The m is the slope and (x1,y1) is the point the line goes through.
If we plugged the point (x1,y1) = (2,4) , along with the slope m = 2/3, then we'll get to what choice 2 is saying
If we tried the other point (5,6), and kept m the same, then we'd get to choice 4.
That makes choices 2 and 4 "yes" responses.

At the beginning of spring, Bilquis planted a small sunflower in her backyard. When it was first planted, the sunflower was 10 inches tall. The sunflower then began to grow at a rate of 0.5 inches per week. How tall would the sunflower be after 8 weeks? How tall would the sunflower be after w weeks?
Height After 8 weeks: ?
Height After w weeks: ?
Answer:
Height After 8 weeks: 14 inches
Height after w weeks: y=0.5w+10
Step-by-step explanation:
The equation of the sunflower is y=0.5x+10.
Height after 8 weeks: y=0.5(8)+10
y=4+10
y=14
Height After 8 weeks: 14 inches
Height after w weeks: y=0.5w+10

Write the other side of this equation so it's true for no values of x: }(6x - 10) - x =
Answer:
(6x - 10) - x = 5(x - 2)
Step-by-step explanation:
6x - 10 - x
5x - 10
5x - 10 = 5(x - 2)
5x - 10 = 5x - 10
5x - 10 ÷ 5 = 5x - 10 ÷ 5
x - 2 = x - 2
No solution.
x - 2 + 2 = x - 2 + 2
x = x

Find the value of x in each of the following
a) = 8
b) X = 6
When you plot the following data in a scatter
plot, will your trend line be increasing,
decreasing, or horizontal?
X
2.

Y
3 1 2
0 -2 -7
A. Increasing
B. Decreasing
C. Horizontal
Answer:
B. Decreasing
Step-by-step explanation:
From the table, we can see that as variable x increases, variable y decreases relatively.
If the data points are plotted on a scatter plot, the trend line would be sloping downwards from our left to our right. This shows that the trend line is decreasing because the sloping downwards from the left to the right shows implies a decrease.

State the amplitude and period of f(x) = 3cos9/5t
Answer:
The amplitude is 3 and the period is 10π/9.
Step-by-step explanation:
The standard cosine function is in the form:
[tex]y=a\cos(b(x-c))+d[/tex]
Where |a| is the amplitude, 2π/b is the period, c is the phase shift, and d is the vertical shift.
We have the function:
[tex]f(x)=\displaystyle 3\cos\frac{9}{5}t[/tex]
We can rewrite this as:
[tex]\displaystyle f(x)=(3)\cos\left(\frac{9}{5}\left(t-0\right)\right)-(0)[/tex]
Therefore, a = 3, b = 9/5, c = 0, and d = 0.
Hence, our amplitude is |3| = 3.
Our period will be:
[tex]\displaystyle \text{Period}=\frac{2\pi}{9/5}=2\pi \cdot \frac{5}{9}=\frac{10\pi}{9}[/tex]
Tony is making potato salad for a school picnic. He needs a
total of 3 kilograms of potatoes. He has a 1.5- kilogram bag and an 850-gram bag
How many more grams of potatoes does Tony need? Show your work.
Step-by-step explanation:
for me u need to change in grams
so
3kg=3000g
1.5kg+850g=2350g
so take
(3000-2350)g
ans=650g
Calculate the length of the

A-
12
20
Answer:
x = 40
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
8(8 + x) = 12(12 + 20)
8(8 + x) = 12 × 32 = 384 ( divide both sides by 8 )
8 + x = 48 ( subtract 8 from both sides )
x = 40
A chess player moves a knight from the location (3, 2) to (5, 1) on a chessboard. If the bottom-left square is labeled (1, 1), the translation made is 2 squares up, 1 square right1 square down, 2 squares left1 square down, 2 squares right2 squares down, 1 square right. If the player moves the knight from (5, 1) to (6, 3), the translation made is 1 square up, 1 square right2 squares up, 1 square right4 squares up, 2 squares right2 squares up, 1 square left.
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Translation is the movement of a point either up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units up and b units right, then the new point is at A'(x + b, y + a).
Given that the knight is moved from (3, 2) to (5, 1), hence it is moved 2 squares right and 1 square down.
If the knight is moved from (5, 1) to (6, 3), it is moved 1 square right and 2 squares up.
Describe and correct the error in determining which type of function the table represents.
Answer:
"Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."
Step-by-step explanation:
In reality, the table represents an exponential function instead of a linear function, since values on domain change arithmetically at constant rate, whereas values on range change geometrically at constant rate.
Correct phrase may be: "Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."

OA. 5 units
B. 25 units
C. 7 units
D. 1 unit
Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The two points are C(2,-1) and D(5,3). Using the distance formula, we get
[tex]CD=\sqrt{(5-2)^2+(3-(-1))^2}[/tex]
[tex]CD=\sqrt{(3)^2+(3+1)^2}[/tex]
[tex]CD=\sqrt{(3)^2+4^2}[/tex]
On further simplification, we get
[tex]CD=\sqrt{9+16}[/tex]
[tex]CD=\sqrt{25}[/tex]
[tex]CD=5[/tex]
The distance from point C to D is 5 units. Therefore, the correct option is A.
Which expression is equivalent to this one?
Answer:
1
Step-by-step explanation:
Yes the answer is just 1
Since the power of 2 in the inside will be multiplied by the power of the 4 in the outside will be 8 (The number 11 doesn't change)
A power divided by a power that is equivalent to it is 1
