Answer:
F. y = 9.5x + 22.5
Step-by-step explanation:
let the number of shirts be x
For every shirt he pays $9.50 and $22.5 is the additional price
Answer:
10>-15
Step-by-step explanation:
C. A function can only have one y value for an x value
Answer:
A
Step-by-step explanation:
Noting that i² = - 1
Given
(7 - 3i)(8 + 4i) ← expand factors using FOIL
= 56 + 28i - 24i - 12i²
= 56 + 4i - 12(- 1)
= 56 + 4i + 12
= 68 + 4i → A
Answer:
y = -x + 7

Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
[Standard Form] 5x + 5y = 35
<u>Step 2: Rewrite</u>
<em>Find slope-intercept form.</em>
- Subtract 5x on both sides: 5y = -5x + 35
- Divide 5 on both sides: y = -x + 7
