Its C.
Triangle A is straight up and down and then when you rotate it 90 degrees at point C,It becomes point B.
To solve this, you basically just look at what point it is rotated at, then figure out how far it is rotated.
Hope this helps :)

My first expression answer is y=5 -2x How do I plug it into x-y=1 ?? The Y

Lemur [1.5K]

Answer:

All you need to do is make sure the first expression is solved for y (which it is), and then substitute it into the second expression in place of any occurrences of y:

given the second expression:

x - y = 1

We'll replace y with it's value in the first expression:

x - (y) = 1

x - (5 - 2x) = 1

Now we can expand the resulting equation:

x - 5 + 2x = 1

So neither of the answers provided are correct.

You can then solve for x:

x - 5 + 2x = 1

x - 5 + 5 + 2x = 1 + 5

x + 2x = 6

3x = 6

3x/3 = 6/3

x = 2

After that, you can find y by plugging x into either of the two original equations:

y = 5 - 2x

y = 5 - 2(2)

y = 5 - 4

y = 1

Solve for n: -1/2 (n + 8) +3/4

vlabodo [156]

$\frac{1}{2} (n+8) + \frac{3}{4}$

$\frac{1(n+8)}{2} + \frac{3}{4}$

$\frac{n+8}{2} + \frac{3}{4}$

$\frac{2(n+8)}{4} + \frac{3}{4}$

$\frac{2(n+8) + 3}{4}$

$\frac{2n + 16 +3}{4}$

$\frac{2n + 19}{4}$

A seamstress uses 3/4 yards of material to make a uniform top for band members. If there are 6 3/4 yards of material left on the

dalvyx [7]

Answer:

She can make 9 uniform tops from the material left.

Step-by-step explanation:

Given:

Yards of material left on the bolt = $6\frac{3}{4}$

Material requirement for a uniform top for band members = $\frac{3}{4}\ yd$

To find the number of tops that can be made from the material left.

Solution:

In order to find the number of tops that can be made from $6\frac{3}{4}$ yards of material, we need to divide $6\frac{3}{4}\ yd$ by $\frac{3}{4}\ yd$ .
