The point-slope form:

We have the points (-8, -8) and (-7, 9). Substitute to the formula of a slope:

Put the coordinates of the point (-7, 9) and the value of slope to the point-slope formula:

It would be 7x10^-2
That number would be rounded to 0.07
Answer to first one is X = 9
Answer to second one is X = 35
No. of pink T-shirts was 342
<h3>How to solve it?</h3>
Given: 24% of the T-shirts were white
Let, total number of T-shirts be x
According to question,
Total no. of white T-shirts = 
Total No. of pink T-shirt =
+ 198
Total No. of red T-shirts = 114
According to the question:
+ 198 + 114 = x
312 = x - 
312 = 
x =
x = 600
so No. of pink T-shirts :
+198
= 144 + 198
= 342
Hence total No. of pink T-shirts was 342.

Answer:
A. x^2+6x-15
Step-by-step explanation:
(3x^2+2x-8)-(2x^2-4x+7) distribute the negative sign
3x^2+2x-8-2x^2+4x-7 combine like terms and simplify leaves us with the answer;
x^2+6x-15
