Answer:
1) C
2)C
3)C
Step-by-step explanation:
in y=mx+b the
m is the slope, b is the y-intercept
y is the output, x is the input
1) The slope is -2 and y-intercept is 3
so y= -2x+3 which is C
2) Slope:6/5 and y-intercept is -4
so y= 6/5x-4 which is C
3) Slope: -1 and y-intercept is 2
You don't put 1x or -1x it's just x.
so y= -x+2 which is A
Hope this helps:)
Well how do you think i feel ?

Answer:
72
Step-by-step explanation:
The triangles are said to be similar. (ΔNPQ ~ ΔRSQ) That means corresponding sides have the same ratio:
NP/RS = NQ/RQ = PQ/SQ = 24/32 = 21/28 = 3/4
This ratio, or scale factor, also applies to the perimeters of the two triangles.
perimeter NPQ / perimeter RSQ = 3/4
Using the given expressions for the perimeters, we have ...
(7x +2)/(10x -4) = 3/4
We can solve this equation in the usual way to find the value of x. Then we can use that value to find the perimeter of ΔNPQ.
4(7x +2) = 3(10x -4) . . . . . multiply both sides by 4(10x -4)
28x +8 = 30x -12 . . . . . eliminate parentheses
20 = 2x . . . . . . . . . . . add 12-28x to both sides
10 = x . . . . . . . . . . . divide both sides by 10
The perimeter of ΔNPQ is ...
7x +2 = 7(10) +2 = 72
The perimeter of triangle NPQ is 72 units.
