x + 9
The area of this shape is 75cm2
Find the perimeter of the shape.
x + 3
2x + 5

Answer:

(x + y)(a + 9)

Step-by-step explanation:

Here, we want to factorize the polynomial

We can do this by taking together like terms

Thus. we have that;

9x + ax + ay + 9y

= x(a + 9) + y(a + 9)

= (x+y)(a+ 9)

Answer:

9

Answer:

We conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.

Step-by-step explanation:

If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.

For example, let the function

[tex]f\left(x\right)\:=\frac{x+3}{x-3}[/tex]

It is clear that the given function becomes undefined at x = 3 in the denominator.

i.e. 3-3 = 0

It means, the function can not have x = 3, otherwise, the function will become undefined.

In other words, if the function has a vertical asymptote at x = 3, then the function is undefined at the value.

Therefore, we conclude that If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.

Answer: D, an enlargement

Step-by-step explanation:

i got the same question

answer:

x^2 - 2 x + 4

explanation: you want to factor the expression using a^3 + b^3= (a+b) (a^2 - ab+b^2)

then

(x,2) x (x^2 - 2x+4)

_________________

           x+2

then reduce so,

(x+2) x (x^2- 2x +4)

_________________

            x+2

then cross out  repeating which is x+2

then you get your answer!

Answer:

(2,-1.5)

Step-by-step explanation:

6x-4y=18

-x-6y=7

Switch the second equation from standard form to y=mx+b form

-x-6y=7→  -x=7+6y → multiply both sides by -1→ x=-7-6y

Substitute all of the things that equal x into the other equation into x

6x-4y=18→ 6(-7-6y)-4y=18

Simplify

-42-36y-4y=18

Bring - 42 to the other side and add like terms

-42-36y-4y=18→ -40y= 60

Solve for y

y=-1.5

Choose an equation and plug y in it.

-x-6(-1.5)=7

-x+9=7

-x=-2

Multiply both sides by -1

x=2

Answer:

216 Minutes

Step-by-step explanation:

2x=18

x=9

Every mile is 9 minutes, so we can multiply 9 by 26:

234 minutes

But he has already ran for 18 minutes, so we can subtract:

234-18=216

Answer:

216mins  

Step-by-step explanation:

first divide 2/18 by 2 to see the rate and you get 1/9 so he runs 1 mile every 9 mins. You multiply 9 by 26 to get your answer and you get 234 subtract 18 and it will take him 216 more mins

Answer:

y = 22; x = 8

y > x

Step-by-step explanation:

A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y represents the larger number and x represents the smaller number, which equations model the situation? Check all that apply.

Let

Smaller Number = x

Larger number = y

larger number is double the sum of 3 and a Smaller number

Sum of 3 and a smaller number = 3 + x

y = 2(3 + x)

y = 6 + 2x (1)

Also

y = 3x - 2 (2)

Equate the equation of the larger number

6 + 2x = 3x - 2

6 + 2 = 3x - 2x

8 = x

x = 8

Substitute x = 8 into (1) to find y

y = 6 + 2x (1)

y = 6 + 2(8)

= 6 + 16

= 22

y = 22

y = 22; x = 8

Therefore,

y > x

Answer:

20 dollars

Step-by-step explanation:

Answer:

Let the number of hours he worked at his weekday job be x and the number of hours he worked at his weekend job be y, then

From (1): 25 + y = 40

y = 40 - 25 = 15.

Therefore, Beneio worked for 25 hours at his weekday job and 15 hours at his weekend job.

Answer:

D = 36.7 feet

Step-by-step explanation:

Diagonal of a Rectangle

Given a rectangle of width W and length L, its diagonal can be calculated as the hypotenuse of a triangle of legs W and L as follows:

[tex]D=\sqrt{W^2+L^2}[/tex]

The dimensions of the living room are 32 feet by 18 feet, thus the diagonal is:

[tex]D=\sqrt{32^2+18^2}[/tex]

[tex]D=\sqrt{1024+324}=\sqrt{1348}[/tex]

D = 36.7 feet

Answer:

y*y*y*y*y

y^5

Step-by-step explanation:

When you multiply exponents with the same base you're supposed to add them so your answer to the first is y^5 but your teacher is being weird and wants you to write it with no exponents so you can just write it 5 times

so number one is y*y*y*y*y

I answered number two in my explanation above

you add the exponents

y^2+y^3=y^5

Answer:

a + c = 95........eq1

15a + 7c = 1,025....eq2

Step-by-step explanation:

Given:

Total number of ticket sold = 95

Total amount collected = $1,025

Price of each adult ticket = $15

Price of each child ticket = $7

Computation:

Number of adult tickets sold = a

Number of child tickets sold = c

So,

Number of adult tickets sold + Number of child tickets sold = Total number of ticket sold

a + c = 95........eq1

and

15a + 7c = 1,025....eq2

Answer:

In step one, -8 - 2 should result in -10, not -6.

Answer:

y = x - 1

Step-by-step explanation:

Find the slope:

(-4 - (-2))/(-3 - (-1))

-2/-2 = 1

y = x + b

Plug in one of the points:

(-1,-2)

-2 = -1 + b

b = -1

y = x - 1

Answer:

SteLet a = short leg of the right triangle, b = the longer leg, and c = the hypotenuse.

The longer leg of a right triangle is 4inches longer than the shorter leg: b = a + 4

The hypotenuse is 8inches longer than the shorter leg:  c = a + 8

Use the Pythagorean Theorem:

a2 + b2 = c2

a2 + (a+4)2 = (a+8)2

a2 + a2 + 8a + 16 = a2 + 16a + 64

a2 - 8a - 48 = 0

Factors to:

(a-12)(a+4) = 0

a = 12, -4

Since we can't have a side of -4, a = 12

Shorter Leg = 12 inches

Longer Leg = 12 + 4 = 16 inches

Hypotenuse = 12 + 8 = 20 inches

Answer:

  see attached

Step-by-step explanation:

There are several ways you can go about this. The most straight-forward (and time-consuming) is to use a calculator to calculate the value for each cell of the table.

If you realize that the first row will be the base of the exponential, then you can finish filling that easily. The first row is completed by ...

  4^1 = 4, 5^1 = 5.

Each row below that is the immediately preceding row multiplied by the number in the first row. For example, to finish the second column, we have ...

  2^4 = 2·8 = 16

  2^5 = 2·16 = 32

__

When calculations are easily defined and repetitive, I like to use a spreadsheet to do them. It avoids errors, and (to me) is less tedious than repeating the same calculation over and over. The first row of this spreadsheet is sequential numbers, as described above. The remaining cells raise the first row value to the left column power.
