Adelle steps:

\frac{4x}{7} - 6 = -20

\frac{4x}{7}  = -14

4x = -98

x = -24.5

Answer:

See Explanation Below

Step-by-step explanation:

Given

\frac{4x}{7} - 6 = 20

Required

Justify each step

Step 1:

\frac{4x}{7} - 6 = -20

This is the question in its original form

Step 2:

\frac{4x}{7}  = -14

Here she performed addition property of an equation by adding 6 to both sides of step 1.

This is shown below

\frac{4x}{7} - 6 +6 = -20 + 6

\frac{4x}{7} = -14

Step 3:

4x = -98

Here she performed multiplication property of an equation by multiplying  both sides of step 2 by 7

This is shown below

7 * \frac{4x}{7} = -14 * 7

4x = -98

Step 4:

x = -24.5

Here she also performed multiplication property of an equation by multiplying  both sides of step 3 by ¼

This is shown below

\frac{1}{4} * 4x = -98 * \frac{1}{4}

x = -24.5

Suppose you work at a retail store that sells teddy bears. You always work 40 hours a week. The amount of your weekly paycheck i
brilliants [131]

a. Remember that f(x) is the amount of money you earned each week. Also note that teddybears = x

<em>f(x) = 5x + 300</em> is your equation

5x + 300 is your expression

-----------------------------------------------------------------------------------------------------------------

b. A reasonable domain can be 0 < x < 50, in which x is the amount you sell. 50 is a bit far out, but it takes into account holidays, as well as places you may sell at that have large amount of people.

-----------------------------------------------------------------------------------------------------------------

c. f(20) means that you sold 20 teddy bears, as 20 replaces x, which (like what was stated above) is the amount you sell

-----------------------------------------------------------------------------------------------------------------

d. Plug in 25 for x.

5x + 300 = t (total amount you make)

5(25) + 300 = t

Remember to follow PEMDAS. First, multiply 5 with 25

5 x 25 = 125

Next, add

125 + 300 = t

t = 425

$425 is the amount you make in a week.

-----------------------------------------------------------------------------------------------------------------

e. Note that you make $425 if you sell 25 teddy bears. Also remember that you are paid a flat $300. Remember the formula:

f(x) = 5x + 300

Plug in 425 for f(x)

425 = 5x + 300

Isolate the x. Do the opposite of PEMDAS. Note the equal sign. What you do to one side, you do to the other.

First, subtract 300 from both sides

425 (-300) = 5x + 300 (-300)

425 - 300 = 5x

125 = 5x

Next, divide 5 from both sides

(125)/5 = (5x)/5

x = 125/5

x = 25

25 teddy bears must be sold

If two lines are perpendicular, which statement must be true? A) The product of their slopes is 1. B) Their slopes are opposites
castortr0y [4]
If two lines are perpendicular, the statement that must be true is : D. The product of their slopes is -1

Lets say that a line has a slope of 2, the line which perpendicular to that line would have a slope of -1/2

Which means, the product would be 2(-1/2) = -1

2x+5x=100 x intercept​
Papessa [141]

This is an equation involving x alone, so the most you can do is solve it:

2x+5x=100x \iff 7x=100x \iff 0=93x \iff x=0
