Answer:

Step-by-step explanation:
We have been given the following equations;
f(x)=x^2−3x+2
g(x)=x^3−8
We are required to determine the composite function (f⋅g)(x). This simply means that we shall substitute the function g(x) in place of x in the function f(x);

Grayson: 35h + 35 = y
Ian: 45h + 15 = y
(Substituting first hour in h)
35h + 35 = y
35(1) + 35
y = 70$ in the first hour for Grayson
45h + 15 = y
45(1) + 15
y = 60$ in the first hour for Ian
Grayson charges > Ian charges
(Substituting second hour in h)
35h + 35 = h
35(2) + 35
105$ in the second hour for Grayson
45h + 15 = h
45(2) + 15
135$ in the second hour for Ian
Grayson charges < Ian charges
Answer:
In the first hour Grayson charges more than Ian.
Answer:
a) 7/5
your y - intercept is wrong btw, the x should always be 0 on a y-intercept so it should be (0,7)
y-7 = 7/5 (x)
Step-by-step explanation:
given the x intercept = (-5,0) and the y intercept = (0,7), we can plug these points into the slop equation
y1-y2
____ = m
x1-x2
m = (0-7)/(-5-0) = -7/-5 = 7/5
slop-intercept form is basically point slope form
y-y1 = m(x-x1)
y-7 = 7/5(x-0)
Answer: 5/21
<u>Do Keep Change Flip (KCF)</u>
Keep: 5/3
Change: ÷ into ×
Flip: 7/1 into 1/7
Your new problem should be: 5/3×1/7
<u>Multiply</u>
5/3×1/7=5/21
Answer:
So to find ratio for questions like these we do x/y
So the ratio for the first one is 5/7
The ratio for the second is 12/7 or 1 5/7
