Answer:
9a.) Rise=5 Run=5 Rate=5/5 which is 1
9b.) Rise=-3 Run=6 Rate=-3/6 which is -1/2
Step-by-step explanation:
488/100, simplified: 122/25
Let Taylor's earnings be t, Andile's earnings be a and that of Favour be f.
Given that t+a+f=380. Also given that Taylor earned 40 less than Andile. That translates to t=a-40. Favour earned twice as much as Taylor.
That is, f=2t. Substitute t=a-40 into f=2t to get f=2(a-40)=2a-80.
Substitute t=a-40 and c=2a-80 into t+a+f=380 to get
a-40+a+2a-80=380.
Combining like terms, we get 4a-120=380. Adding 120 to both sides of the equation, we get, 4a=500 and dividing by 4 on both sides, we get a=125.
Since we want to know what Taylor earned, substitute a=125 back into t=a-40=125-40=85
Therefore, Taylor earned $85!
Answer:
The parent function for a concave up parabola with its vertex at the origin is
y=a(x-h)^2+k.
+a points the parabola concave up
-a points the parabola concave down
h moves the vertex along the x axis that many times
k moves the vertex along the y axis that many times.
