Answer:

Step-by-step explanation:

First, you should replace the variables with the numbers. So,

2(6)-[6-(4+2)/6]

Don't worry, it'll look less confusing later! Next, solve the parentheses that are in the very middle.

2(6)-[6-6/6]

2(6)-[6-1]

12-5

I really hope this helps you!!! Have an amazing day c:

The graph represents the cost y (in dollars) to open an online gaming account and buy x games. Write an equation in slope-interc

Luba_88 [7]

Answer:

y = 10x + 15

Step-by-step explanation:

you pick two points on the line

I picked (3,45) and (6,75)

you subtract the two x’s and y’s

75 - 45 = 30 (30 is the rise) you go up from 45 to 75

6 - 3 = 3 (you move 3 times to the right to get to the 6) so 3 is the run

slope = rise/run so 30/3 = 10

The y-intercept is the place you start on the graph so that is 15

Which value of c would make the following express completely factored? 8x+cy

Artist 52 [7]

The answer is B, 7.

$\sf 8x+2y$

We can factor a 2 out of this: $\sf 2(4x+y)$

$\boxed{\sf 8x+7y}$

We can't factor anything.

$\sf 8x+12y$

We can factor a 4 out of this: $\sf 4(2x+3y)$

$\sf 8x+16y$

We can factor an 8 out of this: $\sf 8(x+2y)$

So your answer is B, 7.
