Answer:
A : $67.60
Step-by-step explanation:
Given:
Sales tax = 4%
She just bought a swimsuit whose full price was $80,
She presented the retailer with a coupon for $15,
Question asked:
What was the total amount that Elaine paid?
Cost price of swimsuit = $80,
She presented the retailer with a coupon for = $15,
Remaining price = 80 - 15 = 65
Now, sale tax imposed = 4% of 65
= 
Sale price = Remaining price after deducting coupon + sale tax
= 65 + 2.60 = 67.60
Thus , $67.60 Elaine paid to the retailer.
Answer:
I'm going to do 1 as an example and using what I've taught you, you have to do the rest. Hope my explanation helps.
Step-by-step explanation:
We are given the points (-2, -4) and (-1, -1)
We need to find the slope.
The equation to do so is y2 - y1 / x2 - x1
lest say:
-2 is x1
-4 is y1
-1 is x2
-1 is y2
-1 - (-4) / -1 - (-2)
3/1 = 3
slope (m) = 3
We already know the y-intercept is 2
The equation of a line is y = mx + b
For this problem we just have to substitute what we already know.
y = (slope)x + y-intercept
y = 3x + 2
*TIP*
If the y-intercept is negative, let's say: b = -5 (using slope 8)
the equation will be y = 8x - 5
Hope this helps. I wish you all the best. :)

x = -1/2

Answer:It would be cut in half
Step-by-step explanation:The momentum of the ball is what speeds it up, like the engine to the car. It needs it to run, so if you cut it in half the speeds are cut in half.
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
