Answer:

Amanda's box holds more popcorn.

Amanda's box holds 70 m³ more than Mary's.

Step-by-step explanation:

Find the volume of both boxes.

13.5 x 10 x 10 = 1350.

20 x 8 x 8 = 1280.

As clearly shown, Amanda's box holds more popcorn.

To find how much more, subtract 1,280 from 1,350 to get 70 m³.

Hope this helps!

Line f has a slope of −6/3, and line g has a slope of −8/4.

Nataliya [291]

Answer:

The option A) is correct

"The lines have proportional slopes" is correct

Therefore the given slopes are proportional to each other

Step-by-step explanation:

Given that Line f has a slope of $\frac{-6}{3}$ , and line g has a slope of $\frac{-8}{4}$

Also given that f and g are distinct lines

To check the proportionality of two slopes :

$\frac{-6}{3}=\frac{-8}{4}$

$-2=-2$

$2=2$

Therefore the given slopes are proportional to each other

Therefore option A) is correct

"The lines have proportional slopes" is correct

Use the intercepts from the graph below to determine the equation of the function.

quester [9]

<u>ANSWER</u>

C) 4x-3y=-12

<u>EXPLANATION</u>

The intercept form of a straight line is given by:

$\frac{x}{x - intercept} + \frac{y}{y - intercept} = 1$

From the the x-intercept is -3 and the y-intercept is 4.

This is because each box is one unit each.

We substitute the intercepts to get:

$\frac{x}{ - 3} + \frac{y}{4} = 1$

We now multiply through by -12 to get

$- 12 \times \frac{x}{ - 3} + - 12 \times \frac{y}{4} = 1 \times - 12$

$4x - 3y = -12$

The correct choice is C.

The equation of the graph y= $x^{3}-2x^{2} +3x-4$ has no symmetry

The equation of the graph y = $x^{3}-2x^{2} +3x-4$

Replace y with -y in the given equation

-y = $x^{3}-2x^{2} +3x-4$

When replacing y with -y gives the different equation. The equation is not symmetric with respect to x axis

Replace x with -x in the given equation

y = $(-x)^{3} -2(-x^{2} )-3(-x)-4$

y = $-x^{3}-2x^{2} +3x-4$

When replacing x with -x gives the different equation. The equation is not symmetric with respect to y axis

Replace x with -x and y with -y in the equation

-y = $(-x)^{3} -2(-x^{2} )-3(-x)-4$

-y = $-x^{3}-2x^{2} +3x-4$

When replacing x with -x and y with -y gives the different equation. The equation is not symmetry with respect to origin.

Hence, the equation of the graph y= $x^{3}-2x^{2} +3x-4$ has no symmetry
