What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
The equation given is 4y-2(1-y)= -44, now solving it for the value of y using distributive property of multiplication over addition :
[tex]\begin{aligned}4y-2(1-y)&=-44\\4y-2+2y&=-44\\6y&=-42\\y&=-7 \end{aligned}[/tex]
Therefore, the value of y is -7

Money is borrowed at 8% simple interest. After one year, 999.00$ pays off the loan. How much was originally borrowed?
Answer:
PV= $925
Step-by-step explanation:
Giving the following information:
Money is borrowed at 8% simple interest. After one year, $999 pays off the loan.
To calculate the original value of the loan, we need to use the following formula:
PV= FV/(1+i*n)
PV= 999/(1+0.08*1)
PV= $925

JK + KL = JL , substitute values
2x + 1 + 6x = 81, that is
8x + 1 = 81 ( subtract 1 from both sides )
8x = 80 ( divide both sides by 8 )
x = 10
Thus JK = 2x + 2 = 2(10) + 1 = 20 + 1 = 21
KL = 6x = 6 × 10 = 60
--------------------------------------------------------------
16
JK + KL = JL , substitute values
2x + x + 2 = 5x - 10 , that is
3x + 2 = 5x - 10 ( subtract 3x from both sides )
2 = 2x - 10 ( add 10 to both sides )
12 = 2x ( divide both sides by 2 )
6 = x
Thus
JK = 2X = 2 × 6 = 12
KL = x + 2 = 6 + 2 = 8
JL = 5x - 10 = 5(6) - 10 = 30 - 10 = 20

Allison wants to buy a skirt that has a regular price of $30. The skirt is on sale for 1/5 off the regular price. Allison has a coupon that will take 1/10 off the sale price. There is no sales tax on clothing. If Allison pays with a $50 bill, how much change will she receive? (Note: Express the answer as dollars.cents.)
Answer:28.4
Step-by-step explanation:
The amount of change received is $28.4.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Regular price = $30
Selling price = (30 - 1/5 x 30) = 30 - 6 = $24
Coupon off = 1/10 x 24 = 2.4
The amount the shirt was bought.
= 30 - 6 - 2.4
= 30 - 8.4
= 21.6
The change was received.
= 50 - 21.6
= $28.4
Thus,
$28.4 is received as changed.

If the length of a rectangle is increased by 120%, and its width is decreased by 20%, what is the percentage change in the area of the rectangle? (rea=length*width)
Answer:
The area of the rectangle is increased in 76 percent.
Step-by-step explanation:
The area of a rectangle ([tex]A[/tex]) is represented by the following formula:
[tex]A = w\cdot l[/tex]
Where:
[tex]w[/tex] - Width.
[tex]l[/tex] - Length.
If length is increased by 120 %and width is decreased by 20 %, the percentage change in the area of the rectangle is: ([tex]l = 2.2\cdot l_{o}[/tex], [tex]w = 0.8\cdot w_{o}[/tex])
[tex]A = (2.2\cdot l_{o})\cdot (0.8\cdot w_{o})[/tex]
[tex]A = (2.2)\cdot (0.8)\cdot w_{o}\cdot l_{o}[/tex]
[tex]A = 1.76\cdot A_{o}[/tex]
The area of the rectangle is increased in 76 percent.

A piece of wood has a width of 5 cm and a height of 10 cm. Its volume is 100 cm? What is the length of the wood?
10,000 cm
2 cm
515 cm
50 cm
Answer:
The length of a piece of wood is 2 cm.
Given:
volume = 100 cm³
width = 5 cm
height = 10 cm
length = ?
Volume is computed by multiplying the length, width, and height of an object.
Volume = length * width * height
100 cm³ = length * 5 cm * 10 cm
100 cm³ = length * 50 cm²
100 cm³ / 50 cm² = length
2 cm = length
to check:
100 cm³ = 2 cm * 5 cm * 10 cm
100 cm³ = 10 cm² * 10 cm
100 cm³ = 100 cm³
Answer:
2 cm
Step-by-step explanation:
write out equation for volume for a Rectangular prism and plug in the numbers you have. Multiply the Width and Height and divide the volume with the product of Width X Height

The requried value of the unknowns in the function is given as a = 4 and b = 3.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
As mentioned in the question,
For even function table is given,
x ⇒ -2, 0, 2, 3
f(x) ⇒ 4 5 a 7
For even function,
f(x) = f(-x)
From table,
f(2) = f(-2) = 4
So, a = 4
For odd functions,
f(-x) = -f(x) [f(-x) ≠ f(x)]
f(-2) = -f(2)
b = 3, [f(2) = -3 from table]
Thus, the requried value of the unknowns in the tables is given as a = 4 and b = 3.

HELP! i’m confused! question is in the picture
Answer:
[-6,-3]
Step-by-step explanation:
So we have the compound inequality:
[tex]2x+7\leq x+4\leq 3x+16[/tex]
Let's solve for each of the inequalities:
1)
We have:
[tex]2x+7\leq x+4[/tex]
Subtract x from both sides:
[tex]x+7\leq 4[/tex]
Subtract 7 from both sides:
[tex]x\leq -3[/tex]
So that's one of our answers.
2)
We have:
[tex]x+4\leq 3x+16[/tex]
Subtract 3x from both sides:
[tex]-2x+4\leq 16[/tex]
Subtract 4 from both sides:
[tex]-2x\leq 12[/tex]
Divide both sides by -2. Since we're dividing by a negative, flip the sign:
[tex]x\geq -6[/tex]
Therefore, our entire answer is:
[tex]-6\leq x\leq -3[/tex]
This means all values in between -3 and -6 including -3 and -6.
In interval notation, this is:
[tex][-6,-3][/tex]
So, A is -6.
And B is -3.
And we're done :)
