Answer:
x = -1
y = -2
Step-by-step explanation:
5x + 2y = -9 2y = -9 - 5x y=(-9-5x)/2
3x + 4y = -11
3x+4[(-9-5x)/2] = -11
3x+( -36-20x)/2 = -11
3x-18-10x = -11
-7x = 7
x = -1
y = -2

A, D, E
step-by-step explanation:
- in order to find the range, you have subtract the smallest number from the largest number in the set of values you are given
A — 13 - 1 = 12
B — 15 - 7 = 8
C — 12 - 12 = 0
D — 28 - 16 = 12
E — 36 - 24 = 12
F — 29 - 25 = 4
- i took each of the set of values and subtracted the smallest from the largest and got that A, D and E give me 12 for the range
