-98=7(n-7)

-98=7n-49

7n=-98+49

7n=-49

Therefore n=-7, as 7(-7)=-49.

Answer:

$2$

Step-by-step explanation:

Given:

$-2(1-4x)=3x+8$

Let's distribute the parenthesis

$-2+8x=3x+8$

Let's subtract $-3x$ from both sides

$-2+5x=8$

Let's add $2$ to both sides

$5x=10$

Now, let's divide both sides by $5$ to get $x$ alone

$x=2$

How much is point (-24,-12) dilated by to get to (-18,-9)?

Anna [14]

Answer:

Dilation factor = 0.75.

Step-by-step explanation:

One point on the xy-plane is (-24,-12). The transformation is the dilation which is done on the point and the image is given by (-18,-9). Dilation changes the size of the shape according to the dilation factor. If the original x-coordinate is -24, then the image will be calculated by multiplying the original point with the dilation factor. Therefore, -18= -24 * k, where k is the unknown dilation factor. Simply solve the equation for k.

24k = 18.

k = 18/24 = 3/4 = 0.75.

Similarly, 12k = 9. k = 9/12 = 3/4 = 0.75.

So the point (-24,-12) dilated by k=0.75 to get to (-18,-9)!!!
