Answer:
Step-by-step explanation:
Trying using photo math or on google there is actually a slope calculator called functions calculator in stupid sorry for not answering it lol
for
x
y
: To do this we must divide each side of the equation by
2
y
which will give us
x
y
while keeping the equation balance.
To find both f(8) and f(-5), we will need to plug in their values for x and solve for each. Then, we can subtract them to find the final answer.
Finding f(8):
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
Finding f(-5):
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
Subtracting f(8) and f(-5):
f(8) - f(-5)
22 - - 17
22 + 17
39
Hope this helps!! :)
