A(n)=-1(-3^n)
3, -9, 27, -81
Answer:
s = -77
Step-by-step explanation:
Answer:
whole milk 4 ---------------- 32 ounces
skim milk 0 ---------------- x ounces
Mixture 2.5 ---------------- 32 + x ounces
4*32+0x =2.5(32 +x)
128+0x= 80+2.5 x
0 x + -2.5 x = 80 - -128
-2.5 x = -48
/ -2.5
x = 19.2
19.2 ounces of 0 % fat skim milk
2x+y=-4
5x+3y=-6
multiply first equaton by -5 and second by 2 then add them
-10x-5y=20
<u>10x+6y=-12 +</u>
0x+1y=8
y=8
the y value is 8
