Answer:

Step-by-step explanation:

It seems this system of equations would be solved easier using the elimination method (the x and y values are lined up).
Multiply everything in the first equation by -2 (we want the 4x to be able to cancel out with a -4x).

Now line up the equations (they are already lined up - convenient) and add them from top to bottom.

The -4x and 4x are opposites, so they cancel out.
Adding 6y and 2y gives you 8y, and adding -12 and 4 gives you -8.

Divide both sides by 8.

Since you have the y-value you can substitute this in to the second (or first equation, it doesn't necessarily matter) equation.

Simplify.

Add 2 to both sides.

Divide both sides by 4.

The final answer is
.

Multiply the number of pencils by the length to get total centimeters first, then convert to meters:
24 x 19 = 456 cams.
1 meter = 100 cm
Divide total cm by 100 to get meters
456 / 100 = 4.56 meters
Answer is B, -6 - -6 = 0 7-3=4 0/4 =0
A’s slope has no meaning
C’s slope is 1
D’s slope is -14/-18
Answer:
p = 4√5
Step-by-step explanation:
To solve for P, we can use the Pythagorean theorem.
a²+b²=c²
(8)²+(p)²=12²
64+p²=144
p²=80
√p=√80
p = 4√5
X=60 and if you plug in 60 to that equation, it equals 15.
1/4 x 60 =15
Hope this helps!
