Step-by-step explanation:

Cost = 15 + 3t

22.5 = 15 + 3(2.5)

22.5 = 15 + 7.5

22.5 = 22.5 <— true

Answer:

true

Step-by-step explanation:

2.50 x 3 = 7.50

15 + 7.50 = 22.50

22.50 = 22.50

slope is 0 , y intercept is 1 the answer is j x

Answer:

slope:(-0.5) y-intercept:0 equation:(-0.5x)

Step-by-step explanation:

To find slope, you use the formula y2-y1/x2-x1

For example, I used the first 2 sets of coordinates used in the table

(-2,1)&(-1,0.5)

First Part: 0.5-1= -0.5

Second part: -1-(-2)=1

Third Part: -0.5/1=(-0.5)

Y-intercept: In order to find the y-intercept, x needs to be 0.

Y-intercept=0

Equation:

The form for the equation should be, mx+b

B=Y-intercept

M=Slope

X=variable

The slope is -0.5 and you add the x after -0.5

Since the y-intercept is 0, it doesn't have a value so putting 0 at the end would be unnecessary. Slope:-0.5x

Which point is the image of (-7,1) reflected across the y-axis? "-enter answer as an ordered pair without
spaces**

Answers

Answer:

The image point of (-7, 1) after reflection across the y-axis is:

(7, 1)

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-7, 1)

Let say the point is A(-7, 1).

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-7, 1) → A'(-(-7), 1) → A'(7, 1)

Therefore, the image point of (-7, 1) after reflection across the y-axis is:

(7, 1)
