What is the equation in point-slope form of the line passing through (−2, 0) and (2, 8)? (1 point) y = 2(x + 2) y = 2(x − 2) y =

Sonja [21]

Answer: $y=2(x+2)$

Step-by-step explanation:

The slope of the line is

$y=\frac{8-0}{2-(-2)}=\frac{8}{4}=2$

Using the point (-2, 0) to substitute into point-slope form, we get the equation to be $\boxed{y=2(x+2)}$

Two sides of a triangle are equal in length and double the length of the shortest side. The perimeter of the triangle is 36 inch

chubhunter [2.5K]

Answer:

Two equal sides = 14.4 inches each

Shortest side = 7.2 inches

Step-by-step explanation:

a + b + c = 36

a = b

a = 2c

then:

c = a/2

a + a + a/2 = 36

2a + a/2 = 36

4a/2 + a/2 = 36

5a/2 = 36

a = 2*36/5

a = 72/5

a = 14.4

a = 2c

14.4 = 2*c

c = 14.4/2

c = 7.2

a = b

b = 14.4

Check:

14.4 + 14.4 + 7.2 = 36
