The answer is (-2, -1) hope this helps!
Yo has to factor since we assume that
if you have xy=0, x and y=0
7n^2-48n+36=0
trial and error
(7n-6)(n-6)=0
set each to zero
7n-6=0
add 6
7n=6
divide 7
n=6/7
n-6=0
add 6
n=6
n=6/7 or 6
Answer:
f = 3 1/2
Step-by-step explanation:
f = 2t - 3f Substitute 7 for t
f = 2(7) - 3f Multiply
f = 14 - 3f
+3f + 3f Add 3f to both sides
4f = 14 Divide both sides by 4
f = 3 1/2
