Answer:
f(0)=5(0)-20
f(0)= -20
y- intercept is (0,-20)
Answer:
f = 5 + -20x-1
Step-by-step explanation:
Simplifying
f(x) = 5x + -20
Multiply f * x
fx = 5x + -20
Reorder the terms:
fx = -20 + 5x
Solving
fx = -20 + 5x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = -20x-1 + 5
Simplifying
f = -20x-1 + 5
Reorder the terms:
f = 5 + -20x-1
7x - 4 + x = -1 + 13x + 7
Show work
Answer:
7x-4+x=-1+13x+7
8x-4=13x+6
add 4 to both sides
8x-4+4=13x+6+4
8x=13x+10
subtract 13x from both sides
8x-13x=13x+10-13x
-5x=10
divide both sides by -5
-5x÷-5=10÷-5
x=-2

Here are two rectangles.

A
The length of rectangle B is 25% greater than the length of rectangle A.
3
The width of rectangle B is three fifths x the width of rectangle A.
Find the fraction of area of rectangle b over area of rectangle a
Give your answer in its simplest form.
Answer:
[tex] \frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}[/tex]
Step-by-step explanation:
Let the length of rectangle A be x units.
So, length of rectangle B
= x + 25% of x
= x + 0.25x
= 1.25x
Let the width of rectangle A be y units
So, Width of rectangle B
[tex]= \frac{3}{5}\times x\\
=0.6x [/tex]
Area of rectangle A = xy
Area of rectangle B
= 1.25x * 0.6y
= 0.75xy
[tex] \frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{xy}{0.75xy}\\\\
\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{1}{0.75}\\\\
\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{100}{75}\\\\
\red{\bold{\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}}} \\\\[/tex]

A $20.00 pair of jeans is discounted 20%. What is the final price of the jeans?
Answer:
It should be 4 dollars I believe
Step-by-step explanation:
Answer:
It is given that a $20.00 pair of jeans is discounted 20%. We need to find the final price of the jeans. Therefore, the final price of the jeans is $16.00
Final price of the jeans = 20 - 20% of 20
Therefore, the final price of the jeans is $16.00.
Find the product of 2r^2(6r^3+14r^2-30r+14)
Answer:
12 [tex]r^{5}[/tex] + 28 [tex]r^{4}[/tex] - 60 r³ + 28 r²
Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)
[tex]a^{m} * a^{n} = a^{m+n}[/tex]
2r²(6r³ + 14r² - 30r + 14) = 12 [tex]r^{5}[/tex] + 28 [tex]r^{4}[/tex] - 60 r³ + 28 r²
Answer: 2r2(6r3+14r2−30r+14)
Step-by-step explanation:
Apply the distributive property
2r2(6r3)+2r2(14r2)+2r2(−30r)+2r2⋅14
Simplify
2⋅6(r2r3)+2⋅14(r2r2)+2⋅−30(r2r)+28r2
Simplify each term
12r5+28r4−60r3+28r2

Jerry purchases a used sofa for $275. He cleans and reupholsters the sofa to make it look brand new. After all the improvements, Jerry sells the sofa for 40% more than what he originally purchased it for. What was the profit Jerry made after selling the sofa?
Answer:
$110Step-by-step explanation:
Step one:
we are told that the cost of the sofa is $275
also, he sells it for 40% more of the cost price
let us find 40% of $275
=40/100*275
=0.4*275
=110
=$110
Step two:
This means that the selling price is 275+110
=$385
profit = selling price- cost price
profit=385-275
profit=$110
