Answer:

( 2x+5) (5x-2)

Step-by-step explanation:

Answer:

x=-16

y=40

Step-by-step explanation:

y=-4x-24

y+2x=8

its the same y. Use substitution

(-4x-24)+2x=8

-2x-24=8

-2x=32

x=-16

We found x!

substitute x in either equation

y+2x=8

y+2(-16)=8

y-32=8

y=40

Answer: (-16, 40)

Step-by-step explanation: Using substitution, you can but the first y=-4x-24 into the second equation y+2x=8. So, you take what y is (which is -4x-24) and substitute it for the second y in the equation y+2x=8.

Your equation should now look like this (-4x-24) + 2x = 8.

You can then solve -4x -24 +2x =8. Combine like-terms (-4x+2x) to get -2x-24=8. Then use inverse operations and add 24 from both sides (so from the -2x-24 side and 8 side). This will then give you -2x=32. divide both sides from -2x to get:

x = -16

Then, plug in x= -16 into the first equation (y= -4 (-16) - 24). Then use PEMDAS and multiply -4 and -16 to get +64. Subtract 24 to get:

y = 40

Answers:

In 2003, there were 32 ...

The model predicts ... 40 ...

... 8 below what the model predicted

In 2003, there were 32 ...

-> We find the x-axis of 2003 and look up until we hit the line, then we find the y-coordinate for that point

-> 32

The model predicts ... 40 ...

-> The green 8 with an arrow shows the prediction

-> 40 - 8 = 32

-> 40

... 8 below what the model predicted

-> The green 8 shows the difference in the prediction and the actual participation

-> 8

Answer:

We conclude that:

[tex]3\cdot \:2\begin{pmatrix}-2&3&0\\ -4&2&6\\ 6&-5&6\end{pmatrix}=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}[/tex]

Hence, option B is correct.

Step-by-step explanation:

Given the expression

[tex]3\times 2\begin{pmatrix}-2&3&0\\ \:-4&2&6\\ \:6&-5&6\end{pmatrix}[/tex]

solving

[tex]3\times 2\begin{pmatrix}-2&3&0\\ \:-4&2&6\\ \:6&-5&6\end{pmatrix}[/tex]

Scalar Multiplication: Multiply each of the matrix elements by a scalar

[tex]=\begin{pmatrix}3\cdot \:2\left(-2\right)&3\cdot \:2\cdot \:3&3\cdot \:2\cdot \:0\\ 3\cdot \:2\left(-4\right)&3\cdot \:2\cdot \:2&3\cdot \:2\cdot \:6\\ 3\cdot \:2\cdot \:6&3\cdot \:2\left(-5\right)&3\cdot \:2\cdot \:6\end{pmatrix}[/tex]

Simplify each element

[tex]=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}[/tex]

Therefore, we conclude that:

[tex]3\cdot \:2\begin{pmatrix}-2&3&0\\ -4&2&6\\ 6&-5&6\end{pmatrix}=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}[/tex]

Hence, option B is correct.

Step-by-step explanation:

The circumference of a wheel is directly scaled to its radius.  We're told that Kevin's tricycle wheel is eight inches in radius, and Monica's bicycle wheel is 16 inches in radius.  Because 16 is equal to 2×8, we know that Monica's wheel is twice as big as Kevin's.

Answer:

4

Step-by-step explanation:

Since both of these numbers are negative, it means that the answer will be negative, since 2 negatives make a positive, since now you know that, you can easily do 32/8 which is 4.

-32/ -8 = 4

Check....

-8 * 4 = -32

-32 / 4 = -8

When there is a negative number and a positive number being multiplied or divided by, it will always result in a negative number.

Answer:

36 feet long.

Step-by-step explanation:

If the longest wall in the living room is referring to the side that I have drawn over in white and red in the attached image, or if it is the leftmost wall, then that wall is 36 feet long. For every half inch, it is 6 feet, so because there are 6 'half inches' in 3, you multiply 6 feet by the 6 half inches there are, and get 36. There are simpler ways to solve it but I can't take a picture of my work, so I hope this helps. Good luck.

The actual length of the longest wall in the living room is  36 feet.

The blueprint is a scale drawing of the apartment. A scale drawing is a smaller diagram of a large image. A scale drawing is reduced by constant dimensions.

Looking at the given image, the longest wall is 3 inches.

The length of the longest wall in the apartment : (3 in x 6) / 0.5

=18 / 0.5

= 36 feet

Answer:

a= -10

Step-by-step explanation:

To do this you would need to isolate a, or make a stand alone on its side of the equation

a-2=-12    Original equation

a-2+2 = -12+2     Isolating the variable(adding the 2 will cancel the -2 on the left side of the equation)

a= -12+2             Simplification

a= -10                 The answer!!!
