Answer = 8y

Step-by-step explanation:

if an octagon has 8 sides and each side is = to y then the total side length in the primiter is = to 8sides times y or 8y

a) Solution for x:

x = {x / -3 ≤ x ≥ 2; x≠-2;1)

Interval notation:

(-∞, -3] ∪ (-2, 1) ∪ [2, +∞)

Step-by-step explanation:

Rational Inequality is inequality with rational numbers or expressions.

The symbols in inequality are:

Less than (<)

Greater than (>)

Less than or equal to (≤)

Greater than or equal to (≥)

In fraction or rational expression, the denominator is not 0. A zero-denominator renders the expression undefined.

Given:  

(x+3)(x-2)/(x+2)(x-1)≥0

The rational expression:

Numerator:  (x+3)(x-2)

Denominator:  (x+2)(x-1) where x ≠ -2 and x ≠ 1 because the values -2 or +1 will make the expression undefined

Find the solution for x by equation the factors in enumerator to 0:

x+3 ≥ 0  

x ≥ -3

x ≤ -3

x - 2 ≥ 0

x ≥ 2

But:

x ≠ -2

x ≠ 1

Hence:

Solution for x:

x = {x / -3 ≤ x ≥ 2; x≠-2;1)

Interval notation:

(-∞, -3] ∪ (-2, 1) ∪ [2, +∞)

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

b) Take the root of both sides and solve

Inequality Form:

− 4 ≤ x < 2  or  x ≥ 3

Interval Notation:

[ − 4 , 2 ) ∪  [ 3 , ∞ ]

Answer:

Step-by-step explanation:

Is 1.450 correct?  145 would make more sense.  I'd even go with 1,450, just for a laugh.  I'll assume 1.450 is the correct number here.  I'll assume assute the question eventually asks how old are A and B.

A = 49(B)

A+B=1.450

Substitute:  

49B+B=1.450

50B = 1.450

B = 0.029

A = 49(B)

A = 49*(0.029)

A = 1.421

Answer:

domain 0 ≤ y ≤ 72 and the range is 0 ≤ y ≤ 6

Step-by-step explanation:

The loan repayment is an illustration of a linear function.

He will finish paying the loan after 6 months.

A linear function is illustrated as: [tex]\mathbf{y = mx + b}[/tex]

In this case:

Because the amount reduces after each monthly payment, the value of m will be taken as: m = -325

So, we have:

[tex]\mathbf{y = -325x +1950}[/tex]

When he finishes paying the loan, we have: y = 0.

So, the equation becomes

[tex]\mathbf{0 = -325x +1950}[/tex]

Add 325x to both sides

[tex]\mathbf{325x =1950}[/tex]

Divide both sides by 325

[tex]\mathbf{x =6}[/tex]

Hence, he will finish paying the loan after 6 months.

Step-by-step explanation:

25x4.8=120

10×4.8=48

I got 4.8 by doing this:

I already knew that 25×5 would equal 125.

but since they wanted 120, I instead multiplied 25 by 4 with decimals from 1-10 until I got 120, then I multiplied that with the 10 pages to get my answer.

Answer:

x = -1

Step-by-step explanation:

3(x + 2) = 2x + 5

Use the distributive property on the left side.

3x + 6 = 2x + 5

Subtract 2x from both sides. Subtraction property of equality.

x + 6 = 5

Subtract 6 from both sides. Subtraction property of equality.

x = -1

Answer:

0.08

Step-by-step explanation:

5 ^-2 * cube root of 8

first of all, let us solve 5^-2

using the law of indices;

a^-2 = 1 / a ^2

following this law, we have;

5^-2 = 1 / 5^2

we know that 5^2 = 25

therefore,

5^-2 = 1 / 25

now, let is continue by solving the cube root of 8

now, there are three ways of solving this;

we could just simply think of any number that when multiplies itself three times times, it gives 8, or we could just simply use a calculator

regardless of what we use, we have to end up with the number 2 as the answer

leading is to our conclusion.

from all our solution, we have reduced our question to;

1 / 25 ( which is 5^-2) * 2 ( which is the cube root of 8 )

= 1 / 25 * 2 / 1

note that 2 is the same as 2 / 1. We put it like this when we want to carry out an operation on an integer ( e.g. 2) and and a fraction ( e.g. 1 / 25 )

so,

1 / 25 * 2 / 1 =

2 / 25 ( the two multiplies the 1 in 1 / 25 and the 25 multiplies the 1 in 2 / 1)

leaving our answer in decimal, we have;

0.08

Answer:

B. y – 270 = 45(x – 2) ; $450

Step-by-step explanation:

In February, you have a balance of $270 in your bank account.

In January, you have a balance of $270 - $45 = $225 in your bank account.

In December, you have a balance of $225 - $45 = $180 in your bank account.

y = $180 + $45x, where x = 1, 2, 3, 4...

Balance in June: x = 6

y = $180 + $45x = $180 + $45×6 = $180 + $270 = $450

The complete question is:

In February, you have a balance of $270 in your bank account. Each month you deposit $45. Let January = 1, February = 2, and so on. Write an equation for this situation. Use the equation to find the balance in June.

Answer:

$450 in June

Step-by-step explanation:

$X = 270 + 45 × ( number of month)  

In this problem, February, the month you start with, would be month 0.

June would be 4.

$X = 270 + 45 × 4

= 270 + 180

= $450 in June

$450 in June.

Answer:

Todd I think if I'm wrong sorry

Answer:

Step-by-step explanation:

first you would want to flip the equation then multiply 9 on both sides to get

5(F-32)=9C

Then you would want to divide both sides by 5 which crosses out the 5 from the equation and is moved to the other side which then were you simplify getting

F-32=9C/5

Lastly you want to add 32 to both sides causing - 32 to cross out getting

F=9C/5 +32

making F=9C/5 + 32 our answer
