Answer:

B.) Communative

Step-by-step explanation:

The communitive property is when changing the order of the operands does not change the result. For this equation if you had it as 7 * 5 it would equal 35  and when it is 5 * 7 it would still equal 35.

Answer:

x = 3

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.

First, subtract 4 from both sides:

3x + 4 (-4) = 13 (-4)

3x = 13 - 4

3x = 9

Next, divide 3 from both sides:

(3x)/3 = (9)/3

x = 9/3

x = 3

3 is your answer for x.

Answer:

$9257.5

Step-by-step explanation:

plug into the equation  known variables

Answer:

2257.50

Step-by-step explanation:

B=p(1+r)^t

p= principal amount= $7000 in the saving account

r= interest rate= 15%= .15

t- number of years = 2

B= 7000(1+.15)^2

B= 7000(1.15)^2

B= 7000(1.15)(1.15)

B= 9257.50

She has a total of 927.50 dollars in the account after two years. To find out how much of that is interest we take the Balance and subtract what she invested.

B-p= 9257.50-7000= 2257.50 earned in interest.

Answer:

B) Is the answer.

Step-by-step explanation:

If you have 15 quarters and 32 pennies, you have more than twice the amount of pennies that you do quarters. There is a small chance that it could be a dime or a nickel but this is unlikely. The chance of a quarter and penny falling out is much greater than a dime or nickle.

Answer:

433

Step-by-step explanation:

Break apart into 3 hundreds, 1 ten, and 2 ones.

745 - 300 = 445

445 - 10 = 435

435 - 2 = 433

Answer:

D.) x=3

Step-by-step explanation:

its right

The function will form a vertical asymptote at [tex]x=3[/tex].

Option D: [tex]x=3[/tex] is correct.

Given:

The function is [tex]f (x) = \dfrac{ 6} { x - 3 }[/tex].

We need to find the vertical asymptote of the function.

The given function is a rational function in which the denominator is [tex]x-3[/tex].

Now, the denominator should not be equal to zero.

As the function approaches [tex]x=3[/tex], the function will lead to infinity (positive or negative).

So, the function will form a vertical asymptote at [tex]x=3[/tex].

Option D: [tex]x=3[/tex] is correct.

Answer:

(-6,-2)

Step-by-step explanation:

Hello! Lets get started!

By looking at this problem, we see that both equations equal 2. This makes this problem much easier!

While there are a few methods you could solve this, I will use substitution. First, I need to find what x is in terms of y!

There are many different ways you could do this, here are two:

-x = 2-2y ==> x = -2+2y

-x + 2y = -3x + 8y ==> 2x = 6y ==> x = 3y

For this problem, I am going to use the second answer, x = 3y, as it is simpler!

We need to substitute 3y in for x in either equation; I am going to use the first equation, -x + 2y = 2.

-3y + 2y = 2

-y = 2

y = -2

Now, lets solve for x!

-x + 2(-2) = 2

-x - 4 = 2

-x = 6

x = -6

After plugging the answers into both equations, we see that they are in fact true!

Therefor, our final answer is (-6, -2)

Answer:

The measure of [tex]MN[/tex] :

[tex]MN = 8[/tex]

Step-by-step explanation:

To find the measure of [tex]MN[/tex], add the measure of [tex]RO[/tex] and [tex]ES[/tex] together and divide it by 2 to get the actual measure of [tex]MN[/tex]:

[tex]RO =[/tex] 10

[tex]ES =[/tex] 6

[tex]MN =[/tex] unknown

-Finding the measure of [tex]MN[/tex]:

[tex]10 + 6 = \frac{16}{2} = 8[/tex]

[tex]MN = 8[/tex]

So, the measure of [tex]MN[/tex] would be [tex]8[/tex] .

Answer:

[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]

Step-by-step explanation:

There are a couple of  equivalent expressions to the function [tex]t+0.07t[/tex]. For example:

[tex]t+0.07t[/tex]

Factor:

[tex]t+0.07t=t(1+0.07)[/tex]

If you add the terms inside the parentheses:

[tex]t(1+0.07)=t(1.07)[/tex]

Basically you can add the like terms from the start and get the same result.

[tex]t+0.07t=1.07t[/tex]

Therefore:

[tex]t+0.07t=t(1+0.07)=t(1.07)=1.07t[/tex]

Answer:

y=|x+2|+1

Step-by-step explanation:

the equation for absolute value is y=a|b(x-h)|+k, however, in this case the equation is just y=|x-h|+k

the x value is shifted left 2 so it's |x+2|

the y value is shifted 1 up so it's +1

the equation for the graph is y=|x+2|+1

Answer:

y =|x+2|+1

Step-by-step explanation:

Answer:

Let one no. be 1x

Area of sector: 48π in^2; Option D

Step-by-step explanation:

~ We can see that the bolded portion of the circle must be the the sector that we need to compute the area of... ~

Let us plan out this problem. If we were to find the area of the circle provided a radius of 12 inches, we could create a proportionality between the degree of the sector, and the degree of the circle ( 360 ) and the area of the sector and the area of the circle.

1. To calculate the area of this circle, let us apply the formula πr^2, such that r is 12 inches ( and let us keep π in terms of π ) ⇒ π * ( 12 )^2 ⇒ 144 * π ⇒ Area of Circle: 144π

2. Let us see this as a proportionality:

Degree of sector/ Degree of circle = Area of sector/ Area of circle

3. Now let us say x ⇒ Area of the sector. Substitute values into this formula, and solve for x through algebra:

120 / 360 = x / 144π,

120 * 144π = 360 * x,

17,280π = 360 * x,

x = 17,280π / 360,

Area of sector: 48π in^2

Answer:

x=6 y=-5

Step-by-step explanation:

6x+5y=11

X=1-y

6x=6(1-y)

6x=6-6y

6-6y+5y=11

6-y=11

y=-5

x=1-y

x=1-(-5)

x=6

so,

x=6

y=-5

Answer:

[tex]y = ( - 5) \\ x = 6[/tex]

Step-by-step explanation:

[tex]x = 1 - y \\ 6x + 5y = 11 \\ \\ \\ 6(1 - y) + 5y = 11 \\ 6 - 6y + 5y = 11 \\ - 6y + 5y = 11 - 6 \\ - y = 5 \\ y = - 5[/tex]

[tex]x = 1 - y \\ x = 1 - ( - 5) \\ x = 1 + 5 \\ x = 6[/tex]

Let's check whether the answer is correct.

[tex]6x + 5y = 11 \\ 6 \times 6 + 5 \times ( - 5) = 11 \\ 36 - 25 = 11 \\ 11 = 11[/tex]

Answer:

[tex]25\pi[/tex] or about 78.54 units

Step-by-step explanation:

Since the arc measures 90 degrees, since 90/360=1/4 the segment is 1/4 of the area of the circle. The whole area of the circle is [tex]\pi 10^2=100\pi[/tex], meaning that the area of the segment is [tex]25\pi[/tex] square units, or about 78.54. Hope this helps!

Answer:

x = -1 and x = 5

Step-by-step explanation:

What are the solutions of the equation (x – 3)² + 2(x – 3) -8 = 0? Use u substitution to solve.

(x – 3)² + 2(x – 3) -8 = 0   -------------------------------------------------------(1)

To solve this problem, we will follow the steps below;

let u = x-3

we will replace x-3 by u in the given equation:

(x – 3)² + 2(x – 3) -8 = 0  

u² + 2u -8 = 0  ----------------------------------------------------------- --------------(2)

We will now solve the above quadratic equation

find two numbers such that its product gives -8 and its sum gives 2

The two numbers are 4 and -2

That is; 4×-2 = -8    and 4+(-2) = 2

we will replace 2u by (4u -2u)  in equation (2)

u² + 2u -8 = 0

u² + 4u - 2u -8 = 0

u(u+4) -2(u+4) = 0

(u+4)(u-2) = 0

Either  u + 4 = 0

            u = -4

or

u-2 = 0

u = 2

Either u = -4    or u = 2

But  u = x-3

x = u +3

when u = -4

x = u + 3

x = -4 + 3

x=-1

when u = 2

x = u + 3

x = 2 + 3

x=5

Therefore, x = -1  and  x =5
