Step-by-step explanation:
supplentary means they add to 180
so you can make the formula 180 = 10x + 80
then solve for x
Answer:65miles
Step-by-step explanation:
Let the needed miles be x
(67+62+59+47+x)/5=60
235+x=60×5
235+x=300
x=300-235
x=65miles
General formula to make slope-intercept form
y - y₁ = m(x - x₁)
From the question, we know that
m = 3/4
(x₁,y₁) = (-8,3)
Put the number to the formula
y - y₁ = m(x - x₁)
y - 3 = 3/4(x - (-8))
y - 3 = 3/4(x + 8)
y - 3 = (3/4)x + 6
y = (3/4)x + 9
