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

Solve and check: 3 x2 + 5x + 6 + x − 1 x + 2 = 7 x + 3
vagabundo [1.1K]

Answer:

3x^{2} -2x +5=0

Step-by-step explanation:

Combine liked terms:

3x^{2}+5x+x-1x+6+2=7x+3

3x^{2}+6x-1x+8=7x+3

3x^{2}+5x+8=7x+3

Subtract 3: 3x^{2}+5x+8-3=7x+3-3

3x^{2}+5x+5=7x

Now subtract 7x:

3x^{2}+5x+5-7x=7x-7x

If you want combine liked terms:

3x^{2}-7x+5x+5=0

3x^{2}-2x+5=0

Hope this helps!

Surface area=<br> Volume =<br> Help me please thanks
sleet_krkn [62]
Answers
Surface area is 964 cm2
Volume is 1872 cm3

Step by step
Using L=length, w=width, h= height

Surface area is found by adding the area of all 6 sides. Area is found by multiplying L x W.
8x18 = 144 x2 sides = 288
18x13 = 234 x2 sides = 468
8x13 = 104 x2 sides = 208
Total all sides = 964

Volume of a rectangle is found by multiplying L x W x H
13 x 18 x 8
Volume is 1872 cm3
