Use the Distributive Property and simplify the expression. 4 + 2(3x – 1) + 9

1 answer:

First expand the brackets by multiply everything in them by 2
2(3x-1)=
6x-2
then add the 4 and the 9 to -2 and you get
6x+11 so therefore its a

Helps help and explain it too me im just not getting it :)

Answer:

Step-by-step explanation:

The answer is H because when is says JKLM is similar to PQRS it is say that the sides JK is equal to PQ, that the side KL is equal to the side QR, that the side LM is equal to RS and the side MJ is equal to SP. When trying to use proportions to find out if a figure is similar to another figure you have to divide a side that is congruent to another side length. For example side QR is congruent to side KL and side PS is congruent to the side JM so if you were to QR/KL it would be equal to PS/JM because the figures are similar if that makes sense. ( sorry if this doesn't make sense it's hard to explain this concept virtually.)

Please refer to step-by-step.

Step-by-step explanation:

Let's solve all of these one at a time.

15. -2x - y = -5

To find the x-intercept, we need to equate the value of y to 0.

-2x - 0 = -5

$\dfrac{-2x}{-2}=\dfrac{-5}{-2}$

$x=2.5$

To find the y-intercept, we need to equate the value of x to 0.

-2(0) - y = -5

Now since we cannot have a negative value, we need to divide both sides by -1.

$\dfrac{-y}{-1}=\dfrac{-5}{-1}$

$y=5$

To find the slope form, we can simply transpose the value of -2x to the other sides of the equal sign.

-y = 2x - 5

Now we cannot have a negative value for the slope, we need to divide both sides by -1, leaving us with.

y = -2x + 5

16. 6x + 3y = -9

Let's start with the x-intercept.

6x + 3y = -9

6x + 3(0) = -9

$\dfrac{6x}{6}=\dfrac{-9}{6}$

$x=1.5$

Now we solve for the y-intercept.

6x + 3y = -9

6(0) + 3y = -9

$\dfrac{3y}{3}=\dfrac{-9}{3}$

$y = -3$

Now for the slope.

3y = -6x - 9

Now we need to divide all our variables by 3 to get y.

$\dfrac{3y}{3}=\dfrac{-6x}{3}-\dfrac{9}{3}$

$y=-2x-3$

17. x - y = 4

Let's start with the x-intercept.

x - y = 4

x - 0 = 4

$x=4$

Now we solve for the y-intercept.

x - y = 4

0 - y = 4

-y=4

$\dfrac{-y}{-1}=\dfrac{4}{-1}$

$y = -4$

Now for the slope.

x - y = 4

-y = -x + 4

We need to divide all our variables by -1 to get y.

$\dfrac{-y}{-1}=\dfrac{-x}{-1}+\dfrac{4}{-1}$

$y=x-4$

18. 3x + 4y = 12

Let's start with the x-intercept.

3x + 4y = 12

3x + 4(0) = 12

$\dfrac{3x}{3}=\dfrac{12}{3}$

$x=4$

Now we solve for the y-intercept.

3x + 4y = 12

3(0) + 4y = 12

$\dfrac{4y}{4}=\dfrac{12}{4}$

$y = 3$

Now for the slope.

3x + 4y = 12

4y = -3x + 12

$\dfrac{4y}{4}=-\dfrac{3x}{4}+\dfrac{12}{4}$

$y=-\dfrac{3x}{4}+3$

19. -7x + 2y = -16

Let's start with the x-intercept.

-7x + 2y = -16

-7x + 2(0) = -16

$\dfrac{-7x}{-7}=\dfrac{-16}{-7}$

$x=-2\dfrac{2}{7}$

Now we solve for the y-intercept.

-7x + 2y = -16

-7(0) + 2y = -16

$\dfrac{2y}{2}=\dfrac{-16}{2}$

$y=-8$

Now for the slope.

-7x + 2y = -16

2y = -7x - 16

$\dfrac{2y}{2}=-\dfrac{7x}{2}-\dfrac{16}{2}$

$y=-\dfrac{7x}{2}-8$

20. x - 5y = 55

Let's start with the x-intercept.

x - 5y = 55

x - 5(0) = 55

x = 55

Now we solve for the y-intercept.

x - 5y = 55

0 - 5y = 55

$\dfrac{-5y}{-5}=\dfrac{55}{-5}$

$y=-11$

Now for the slope.

x - 5y = 55

-5y = x + 55

$\dfrac{-5y}{-5}=-\dfrac{x}{-5}+\dfrac{55}{-5}$

$y=-\dfrac{x}{5}-11$
