30+30 is a hour and half of 30 is 15 so do this 8+8 and the add half of 8 and it is 4 so the full thing is 8+8+4+20

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

The answer is 8.

Proportion is defined as the difference between two ratios or fractions that are equal to each other.

The given proportion is

6/x = 21/28

x =  (6*28)/21

x=(6*4)/3

x=8

Hence the solution for the given proportion is 8.

Answer/Step-by-step explanation:

Given,

10x - 3y = 3

3x + 10y = 30

Rewrite both equation in slope-intercept form, y = mx + b.

Where, m = slope of the line.

Thus,

✔️10x - 3y = 3

-3y = -10x + 3

y = 10/3x - 1

Slope of this line would be 10/3

✔️3x + 10y = 30

10y = -3x + 30

y = -3/10x + 3

The slope of this line is -³/10.

✔️The two lines are pendivukar to each other because the slope of one is the negative reciprocal of the other.

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.

Answer:

There are 30 students in class

Step-by-step explanation:

Let x be the total number of students

Then according to the given statement,

40% of x is 12

this can be expressed mathematically as:

[tex]12 = 40\%\ of\ x\\12 = 0.40 * x[/tex]

we can simply use this equation to find the total number of students

[tex]12 = 0.40x[/tex]

Dividing both sides by 0.40

[tex]\frac{0.40x}{0.40} = \frac{12}{0.40}\\x = 30[/tex]

Hence,

There are 30 students in class

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.
