Answer:
y - 9 = -5(x + 4)
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>
Slope <em>m</em> = -5
Coordinate (-4, 9) → x₁ = -4, y₁ = 9
<u>Step 2: Write Function</u>
<em>Substitute into general form.</em>
y - 9 = -5(x - -4)
y - 9 = -5(x + 4)

Answer:
They should purchase the snack with the purple box. This is the answer for 23, i don't know what 24 is sorry.
Step-by-step explanation:
24÷3=8
8×5=40
so the first snacks would cost them $40.
then:
24÷4=6
6×6=36
so the second snacks would cost them $36
Answer: k = 76 degrees
Step-by-step explanation:
A linear pair of angles are always supplementary. (They sum to 180)
If the pair of angles are k and 104, they have to add up to equal 180.
180-104= 76
K has to equal 76 degrees

Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
