Answer:
Step-by-step explanation:
Y=-3x+15
Comparing to y = mx + c
Slope m = -3
Intercept c = 15
I’m pretty sure k=59 degrees since the area of a triangle is 180 so you just subtract the angles you already have to find the other one
Answer:
24ft
Step-by-step explanation:
Pythagorean Theorem!!
------------------------
In this case, the ladder is c, and the base is b.
------------------------
Plug the numbers in the formula.
------------------------
Solve.
Y - 3 = 4x + 8
y = 4x + 11
slope = 4
2.4 hours
You can get this by setting up the equation:
x/4 + x/6 = 1
Where x is equal to the amount of hours spent working. In this equation x/4 would be Doug. In 4 hours he would paint on room. x/6 would be Elaine. When you add them together using common denominators, you can find x.
