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 $\boxed{y=2(x+2)}$

your gym membership cost $33 per month after an initial membership fee. you paid a total of $228 after 6 months. writer an equat

grin007 [14]

Answer:

what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9-month total cost of $327

Step-by-step explanation:

cost = $33 per month + fee

1. c(m) = 33m + f

33(6) + f = 228

198 + f = 228

f = $30 membership fee

c(m) = 33m + 30

2. at 9 months: 33(9) + 30 = $327

hopefully this helps :)

When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?

Fantom [35]

The answer is Multiply each side by −8, subtract 35 from each side

 $- \frac{1}{8}(x+35)=-7$

Multiply each side by -8:
 $(-8)(- \frac{1}{8})(x+35)=(-8)(-7) \\ \\ 
1(x + 35) = 56 \\ 
x + 35 = 56$

Subtract 35 from each side:
 $x + 35 -35 = 56-35 \\ \\ 
x + 0 =21 \\ \\ 
x = 21$
