Cost of paying someone to rake her yard for for years would be $80.
The leaf blower would cost $70.
So she would save $10 buy buying the leaf blower.
Answer:
y = -2x +15
Step-by-step explanation:
The point-slope form of the equation for a line through (h, k) with slope m is ...
... y - k = m(x - h)
For your point (h, k) = (5, 5) and slope m = -2, the equation in point-slope form is ...
... y - 5 = -2(x - 5)
Simplifying, we get
... y - 5 = -2x +10
Adding 5 puts the equation into slope-intercept form, as you want.
... y = -2x +15
Answer:
6509.84 ft to the nearest hundredth.
Step-by-step explanation:
We have a right triangle in which the opposite side is 1479 ft and we need to find the adjacent side:
Tan 12.8 = opposite / adjacent side
tan 12.8 = 1479/ x
x = 1479/tan 12.8
= 6509.84 ft.
