Larry and Donna bought a sofa at the sale price of $1,344. The original price of the sofa was $1,920. Find the discount rate

velikii [3]

Answer:

30% discount

Step-by-step explanation:

To find the percent discount write a proportion.

$\frac{1344}{1920}=\frac{x}{100}$

Cross multiply numerator with denominator of each fraction to solve for x.

1344(100) = 1920(x)

134400 = 1920x

70 = x

This means you pay 70% of the price. The discount was 30%.

What are two different way of factoring -3x-9? Select all that apply

Ghella [55]

Options:

A. –3(x + 3)

B. 3(x + 3)

C. 3(–x – 3)

D. –3(x – 3)

Answer:

A and C

Step-by-step explanation:

Given

$-3x - 9$

Required

Factorize

The options are not given; So, I'll answer on a general term

$-3x - 9$

Express -9 as -3 * 3

$-3x - 9 = -3x - 3 * 3$

Then factorize 3 out of the expression as:

$-3x - 9 = 3(-x - 3)$

Another way is to factor -3 out of the expression as:

$-3x - 9 = -3x - 3 * 3$

$-3x - 9 = -3(x + 3)$

The line graphed below has a slope of ____. -3 -1/3 1/3 3

goblinko [34]

The line drops 3 squares for each one it moves to the right, so the slope is
.. -3/1 = -3

The 1st selection is appropriate.

_____
Given the choices, you can tell at a glance that -3 is the correct one. When it goes down to the right, the slope is negative. when the angle is steep, the slope has a magnitude greater than 1. Of the negative choices offered, {-3, -1/3}, the obvious choice is -3.

A line has a slope of ±1 when it makes a 45° angle with the x- and y-axes. Steeper than that is a slope whose magnitude is greater than 1. Shallower than that, and the slope has a magnitude less than 1.
