If ƒ(x ) = x 2 + 1 and g(x ) = 3x + 1, find ƒ(-1) + 5g(-3). -40 -38 7

EastWind [94]

$f(x) = x^2 + 1 \\ 
g(x) = 3x + 1$

You can do this in parts.
$f(-1) = (-1)^2 + 1 = 1 + 1 = 2$
g(-3) = 3(-3) + 1 = -9 + 1 = -8
So, 5g(-3) = 5(-8) = -40.
So f(-1) + 5g(-3) = 2 - 40 = -38

Or you can do this as one big chunk.
f(-1) + 5g(-3)
$=[(-1)^2+1] + 5[3(-3) + 1] \\
= (2) + 5(-9 + 1) \\
= 2 + 5(-8) \\
= 2 - 40 \\ = -38$

Solve for j. -13j - 20 = -8j + 20

aleksley [76]

Answer:

j = -8

Step-by-step explanation:

-13j - 20 = -8j + 20

Add 13 j to each side

-13j+13j - 20 = -8j+13j + 20

-20 = 5j+20

subtract 20 from each side

-20-20 = 5j +20-20

-40 = 5j

Divide by 5

-40/5 = =5j/5

-8 =j
