Answer:

x= 2

y = 20

Step-by-step explanation:

y = 6x + 8

y = –4x – 2

y = 4 (6x + 8 )

y = 6 (–4x – 2)

y = 24x + 32

y = –24 -12

___________

y = 20

input that back into the equation to find x

20 = 6x + 8

20 - 8 = 6x

12 = 6x

x= 2

If a circle has circumference c, what is it’s are in terms of C

Scilla [17]

$\text {Circumference = } 2 \pi r$

$c = 2 \pi r$

$\text {r = } \dfrac{c}{2 \pi }$

$\text {area = } \pi r^2$

Sub r into area:

$\text {area = } \pi ( \dfrac{c}{2 \pi } )^2$

$\text {area = } \dfrac{\pi c^2}{4 \pi^2 }$

$\text {area = } \dfrac{\ c^2}{4 \pi }$

What is the measure of cº? A. 7.5° B. 15 C. 30° D. 45

mylen [45]

Answer:

x = 15

Step-by-step explanation:

The sum of the angles in a triangle is 180º

3x + 5x + 4x = 180

Combine like terms

12x = 180

Divide both sides by 12

x = 15

C = 5x

C = 5 * 15

C = 75º
