Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -12x + 5
f(-3) is x = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-3) = -12(-3) + 5
- Multiply: f(-3) = 36 + 5
- Add: f(-3) = 41
Answer:
96
lower right
Step-by-step explanation:
Part 1
Givens
a1 = - 20
d = +4
n = 30
Equation
a30 = a1 + (n - 1)d
Solution
a30 = -20 + (30 - 1)*4
a30 = -20 + 29*4
a30 = - 20 + 116
a30 = 96
=====================
Part 2
Formula
Sum = (a1 + L)*n/2
n = 30
So only the two on the right can be considered
a1 = -20
L = 96
Sum = (-20 + 96)30/2 is the bottom right. D if you think of it that way.
100-2=98
6clothes+8clothes=14clothes.
98/14=7.
$7.
I think x might be 1/2 and y is 1. i believe that is the answer
