T=34xP
T= tip for him
P= percent he charges for tip
Step-by-step explanation:
We must realise that the image of the quadratic curve shown is not showing the full curve. Instead it extends further out.
For all quadratic curves, the domain is all x-values.
We see here that this quadratic curve has an absolute minimum at y = -4 and the curve stretches towards positive infinity.
Hence the range is y >= 4.
The correct answers are the 1st and 5th options.
Simplify
f(x) = 3 + 11
Multiple
fx = 3x + 11
<span>Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = 11x-1 + 3
Simplifying
f = 11x-1 + 3
Reorder the terms:
f = 3 + 11x<span>-1</span></span>
Answer:
This is a perfect cube.
The side length is 9 centimeters.
Taking the cube root of the volume will determine the side length

Answer:
a. M=20A
b. k=20
c. $1200
Step-by-step explanation:
<u>Direct proportions
</u>
Two variables are proportional if one of them is the other by a real number. That real number is called the Constant of proportionality. If x and y are proportional, then
y=kx, where k is the constant of proportionality.
The question describes the relationship between the amount of money raised at a charity fundraiser and the number of attendees. If they have five attendees, they raise $100
a.
Let's call A the number of attendees and M the amount of money raised, and
M=kA
We know that M=100 when A=5, so
100=k(5)
This means that
k=20
The equation for the amount raised at the charity event is
M=20A
b.
The constant of variation is k=20
c. If there are 60 attendees (A=60), then
M=(20)(60)=$1200
