Answer:
7pq( 2 + 5r)
Step-by-step explanation:
Hello :
<span>x²- y = 3 ...(1)
x - y = -3 ...(2)
by (2) : y = x+3
subqct in (1) : x²-x-3 = 3
x²-x-6 =0
(x+2)(x-3) = 0
x+2 =0 or x-3 =0
x=-2 or x=3
if x = -2 y = -2+3 = 1
if x=3 y =3+3 = 6
two solutions : ( -2, 1) , (3,6)</span>
Answer:
6
Step-by-step explanation:
f(x) = 2(x-5)
f(8) = 2(8-5)
- parentheses comes first so, 8-5 = 3
- 2(3), so multiply and the final answer is 6
f(8) = 6
