Answer:
A. pi(6)^2* 8
Step-by-step explanation:
Answer:
The slope is 11
Step-by-step explanation:
y=mx+b
Where m is slope, x is variable, and b is the y-intercept.
Step-by-step explanation:
angle x is equal to 65
angles of triangle is equal to 180
Answer: When they work 10 hours each, they both make $300.
kelli y = 20x + 100
karl y = 25x + 50
substitution:
y = 20x + 100
25x + 50 = 20x + 100
-20x -50 -20x -50
--------------------------------
5x = <span>50
</span>5 5
x = 10
(Then plug into any equation)
y = 25x + 50
y = 25(10) + 50
y = 300
When they work 10 hours each, they both make $300.
Every absolute value MUST be 0 or greater (positive); thus, <span>| 5x + 13| = -7 has no solution due to the - number on the right.
