Y = 1/2x + 5...slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular slope is -2/1 or just -2 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2
y int (b) = -2
so ur equation is : y = -2x - 2

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
Answer:
2.6 hours
Step-by-step explanation:
use distance formula: d = r * t
83 = 32t
83/32 = t
2.6 = t
2.6 hours is 2 hours, 36 minutes

The inequality that represent when the accounts fall below
is equal to

Answer:
False
Step-by-step explanation:
1.08/3=0.36 for an apple at HEB
1.15/5=0.23 for an apple at Kroger
36 cents is greater than 23 cents so HEB's apples are more expensive. They are 13 cents more than the Kroger apples. 0.36-0.23=0.13
