What is the simplest form of this expression y2 (3y + 4) + 5y3

Answer:

18

Step-by-step explanation:

3x + (z + 2y) - 12, if x = 3, y = 8 and z= 5.

3*3 + (5+2*8) - 12

9 + (5 + 16) - 12

9 + 21 - 12

30 - 10 - 2

20 - 2

18

Answer:

18

Step-by-step explanation:

First what you would do is plug in the numbers.

3x3+(5+2x8)-12

Then you would multiply 2 times 8 and get 16. Then add 16 and 5 and get 21.

3x3+(21)-12

Then you add 3 times 3 and get 9.

9+21-12

Then you solve left to right. Then you add 9 and 21 and get 30. Last you subtract by 30 by 12 and get 18.

Answer:

D

Step-by-step explanation:

The required line is perpendicular bi sector. So it goes through the midpoint of AB. Find the midpoint of  AB

Midpoint [tex](\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2})\\[/tex]

Midpoint of AB = [tex](\frac{-2 + [-4]}{2} , \frac{8+2}{2})[/tex]

                        [tex]=(\frac{-6}{2} , \frac{10}{2})\\\\=(-3 , 5)[/tex]

Find the slope of AB, [tex]m_{1}[/tex]

slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\[/tex]

         [tex]=\frac{2 - 8}{-4-[-2]}\\\\=\frac{-6}{-4+2}\\\\=\frac{-6}{-2}\\\\=3[/tex]

Slope of the perpendicular line to AB = [tex]\frac{-1}{m_{1}}[/tex]   = -1/3

The required line passes through (-3, 5) and has slope -1/3

Equation of required line : y - y1 = m (x -x1)

[tex]y - 5 = \frac{-1}{3} (x - [-3])\\\\y-5=\frac{-1}{3} ( x +3)\\\\y-5=\frac{-1}{3}x + 3 *\frac{-1}{3}\\\\y-5=\frac{-1}{3}x-1\\\\y=\frac{-1}{3}x-1+5\\\\y=\frac{-1}{3}x + 4[/tex]

y = –1∕3x + 4

Answer: $36

Step-by-step explanation:

3 times 2 times 2 = 12

4 times 2 times 3 = 24

add 12 and 24

answer = $36!

Answer:

x = 6

Step-by-step explanation:

3(x + 2) =24

Divide each side by 3

3/3(x+2) = 24/3

x+2 = 8

Subtract 2 from each side

x+2-2 = 8-2

x = 6

Answer:

B

Step-by-step explanation:

inertia is the tendency to do nothing or remain unchanged

Answer:

B

Step-by-step explanation:

I used the quadratic formula

Answer:

B

Step-by-step explanation:

Given

(x + 5)² = 48 ( take the square root of both sides )

x + 5 = ± [tex]\sqrt{48}[/tex] = ± [tex]\sqrt{16(3)}[/tex] = ± 4[tex]\sqrt{3}[/tex] ( subtract 5 from both sides )

x = - 5 ± 4[tex]\sqrt{3}[/tex] → B

Answer:825

Step-by-step explanation:

Answer:

−30=5(x+1)

Step 1: Simplify both sides of the equation.

−30=5(x+1)

−30=(5)(x)+(5)(1)(Distribute)

−30=5x+5

Step 2: Flip the equation.

5x+5=−30

Step 3: Subtract 5 from both sides.

5x+5−5=−30−5

5x=−35

Step 4: Divide both sides by 5.

5x5=−355

x=−7

Answer:

x=−7

Answer:

x = -7

Step-by-step explanation:

Since this problem has the distributive property, we can simplify the problem.

-30 = 5x + 5

Now we have to subtract 5 from both sides because of the +5.

-35 = 5x

To find the answer, we have to move all the real numbers to one side, the variable on the other. To do this, we can simply divide both sides by 5.

-7 = x

x = -7

Answer:

Step-by-step explanation:

Area of a parallelogram is base times height. So 15x4

It’s 60in^2

So D

Answer:

D. 60 inches^2

Step-by-step explanation:

The area of a parallelogram can be found using:

a=bh

We know that the height is 4 inches, and the base is 15 inches. Therefore, we can substitute 4 in for h and 15 in for b.

a=4*15

Multiply 4 and 15

a=60

Area is always units^2. We know the units are inches, therefore the area is:

60 inches^2, or choice D

Answer:

A. 16 pieces

Step-by-step explanation:

If Jodi learned to sing a total of 4 pieces over the course of 2 weeks of voice lessons, after 8 weeks of voice lessons, Jodi be able to sing 16 pieces.

2 x 2 =4

8 x 2= 16

Therefore the answer is 16.

Hope this helps and I explained it well enough !

Answer:

y=-2x-1

Step-by-step explanation:

Since the m term in this equation (the number that comes right before the x) is -2, that means that the slope of this line is -2.

Answer:

#4: 4 hits

Step-by-step explanation:

At first, you are given the ratio 1/37 which you can scale to 148 by dividing and multiplying both by. So you divide 148/37 to reach 4 and then multiply 4 by 1 to find out that about four hits will prbably be made.

Answer:

OLinear Function

Step-by-step explanation:

In general ,A linear function has the form y = ax + b

so ,the function :

m = 0.25k + 5  is linear .

We just changed

m to y

x to k

a to 0.25

b to 5

Answer:

C

0 No, since the slopes are different.

Step-by-step explanation:

First, solve the second equation.

-6y=-16-4x

6y=16+4x

y=16/6+4/6x

y=2/3x+8/3

Next, look at the equation of a line's format.

y=mx+b

This means y=(m=slope)*x+b[when x=0, y=b]

In the first equation, y=3x-17, we can see that m=3, and b=-17

In the second equation, y=2/3x+8/3, m=2/3, and b=8/3

We know that m is the slope, and 3 does not equal 2/3.

Lines are only parallel when their slopes are the same

Therefore, the two lines are not parallel since the slopes are different.

Answer:

True

Step-by-step explanation:

The points (2,3) and (2,-6) are undefinable because it makes a vertical line. The slope cannot be defined.

Answer:

A' = (-3, 3)

Step-by-step explanation:

If the points are as follows:

A = (-3, -1)

B = (-2, -3)

C = (1, -1)

When reflecting across a y axis the x values remain the same.

When reflecting across y = 1 the y values will remain equal distant from y = 1.

A' = (-3, 3) y value = |-1 - 1| = 2 + 1 = 3

B' = (-2, 5) y value = |-3 - 1| = 4 + 1 = 5

C' = (1, 3) y value = |-1 - 1| = 2 + 1 = 3

Answer:

A' = (-3, 3)
