The rate of f(x) is -47, the rate of g(x) is -84, we can see that the rate of g(x) is twice the rate of f(x).
How to compare the rates of change?For a function f(x), the average rate of change on an interval (a, b) is:
R = [ f(b) - f()]/(b - a)
Here the interval is [-4, -2]
And the functions are:
f(x) = 7x²
g(x) = 14x²
Then the rates are:
f(-4) = 7*(-4)² = 112
f(-2) = 7*(-2)² = 28
Then the rate is:
R = (28 - 112)/(-2 + 4) = -47
g(-4) = 14*(-4)² = 224
g(-2) = 14*(-2)² = 56
the rate is:
R' = (56 - 224)/(-2 + 4) = -84
These are the rates, and we can see that the rate of g(x) is twice the rate of f(x).

What the surface area of a rotating prism?To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.
The total surface area of a Prism = (2 × Base Area) + (Base perimeter × Length).
Here, area of base is Area=2(Base×Height)
= 2(6×4)
= 12 square millimeters
Now, Base perimeter × Length= (5+5+6)×7
= 16×7
= 112 square millimeters
Total area = 12+112
= 124 square millimeters
Therefore, the total surface area is 124 square millimeters.

A local hamburger shop sold a combined total of 376 hamburger and cheeseburgers on Sunday. There were 74 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?
Answers
Answer:
82
Step-by-step explanation:
let X = the number of hamburgers sold
let Y = the number of cheeseburgers sold a combined total of 328 were sold
so: X + Y = 328
cheeseburgers = 3 times the number of hamburgers sold
so: Y = 3X
substitute 3X into the equation for Y
X + 3X = 328
4X = 328
divide both sides by 4 to get the variable X by itself
X = 82
so: 82 hamburgers were sold Friday
Answer:
There were 225 hamburgers sold on Sunday.
Step-by-step explanation:
2h - 74 = 376
h = hamburgers
2h - 74 + 74 = 376 + 74
2h = 450
2h/2 = 450/2
h = 225
Check.
hamburgers + cheeseburgers = total number of burgers
225 + (225 - 74)
225 + 151 = 376

Point Form:
(2, -1)
Equation Form:
x= 2, y= -1
Answer:
x = 2, y = -1
Step-by-step explanation:
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
12x+15y=9,−12x−18y=−6
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
12x+15y=9
Subtract 15y from both sides of the equation.
12x=−15y+9
Divide both sides by 12.
x= 1/12 (−15y+9)
Multiply 1/12 times −15y+9.
x = -5/4y+3/4
Substitute -5y+3/4 for x in te other equation, -12x - 18y = -6
-12 ( -5/4y+3/4) -18y = -6
Multiply −12 times -5y +3/4
15y−9−18y=−6
Add 15y to −18y.
−3y−9=−6
Add 9 to both sides of the equation.
−3y=3
Divide both sides by −3.
y=−1
Substitute −1 for y in x= -5/4y+3/4. Because the resulting equation contains only one variable, you can solve for x directly.
x= -5/4(-1)+3/4
Multiply -5/4 times -1.
x = 5+3/4
Add 3/4 to 5/4 by finding a common denominator and adding the numerators. Then reduce the fraction to lowest terms if possible.
x=2
The system is solved.

C. slope = 2
D. slope = -3
Answers
Answer:
The answer is B - 1/2.
Step-by-step explanation:
Rise over run tells you the slope. You take two points (in this it's (0,-3) and (6,0)) and you see how many units it takes to be on the same y line as the other point. Then you do the same for the x line. You divide the rise (y line) by the run (x line) and that's your slope.

Supplement of 50° = 130°
Step-by-step explanation:
Complementary angles add up to 90°
Supplementary angles add up to 180°
90° - 50° = 40°
180° - 145° = 35°
90° - 27° = 63°
180° - 50° = 130°

Complement 50° = 40°
Supplement 145° = 35°
Complement 27° = 63°
Supplement 50° = 130°
Complement angles = adds up to 90°
Supplement angles = adds up to 180°

-0.5 is greater than -1
use a number line
Step-by-step explanation:
By looking at the number line we can easily tell which integers are greater (larger) than a certain number and which are less (smaller) than the number. When two numbers are located on a number line, the number to the right is larger than the number to the left. –1 is less than –1/2 because it is to the left of –1/2.
