Solve the system of equations.

Mathematics
1 answer:
irinina [24]3 years ago
8 0

Answer:

x=0 y=4

Step-by-step explanation:

12x−5y=−20

y=x+4

substitute y in the first equation with x+4 (the second equation gives you the value of y straight away)

12x-5*(x+4)=-20

12x-5x-20=-20

7x=0

x=0

use this value of x in the second equation

y=0 + 4 = 4

One of the legs of a right triangle measures 8 cm and its hypotenuse measures 14 cm.
Ugo [173]

Answer:

about 11.5 cm.

Step-by-step explanation:

I know the measurement of the other leg is about 11.5 cm. I know because I used the Pythagorean theorem.

a^2+b^2=c^2.

"a" and "b" are the values of the legs of the triangle, while "c" is the measure of the hypotenuse. We know that 8cm is the measure of one of the legs, and 14 cm is a measure of the hypotenuse.

8^2+b^2=14^2 simplified: 64+b^2=196

Then, I subtracted 64 on both sides, so I would have "b" by itself.

b^2=132

Next, I found the square root of both b^2 and 132, so I would find the true value of "b."

b=11.4891252931

So, the measure of the other leg rounded to the nearest tenth is about 11.5.
