Answer: $14.75
I just did $0.75 x 7 = $5.25 and subtracted that from $20. Lmk if this helps or if my answer was incorrect!
Answer:
(-7, 3)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
y - 3 = 4(x + 7)
↓ Compare to Point-Slope Form
Point (-7, 3)
Slope <em>m</em> = 4
0.51 is greater then 0,051
