Answer:
y=−1/7
for the picture is y=-57/7
Step-by-step explanation:
<h3>1. 8= -7y +7</h3>
Switch:sides
-7y+7=8
subtract 7 from both sides
-7y=1
divide both sides by -7
y=−1/7
<h3>2.so for 8/y+7=-7</h3>
multiply both sides by (y+7)
8/y+7(y+7)=-7(y+7)
simplify 8=-7(y+7)
flip
-7(y+7)=8
divide both sides by -7
y+7=-8/7
subtract 7 from both sides
and simplify
y=-57/7
Answer:
0
Step-by-step explanation:
The first equation is for when t = 8.
The second equation is for when t = 10.
The third equation is for all other values of t.
For t = 2, we use the third equation.
f(t) = t² − 3t + 2
f(2) = 2² − 3(2) + 2
f(2) = 4 − 6 + 2
f(2) = 0
