Answer:

“Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate.”

“Look at the graph of the relationship. Count the number of units up and the number of units to the right one must move to arrive at the next point on the graph. Write these two numbers as a fraction.”

“Look at the graph of the relationship. Find the x-value of the point that corresponds to y = 2. That value is the unit rate.”

“Look at the graph of the relationship. Find two points which have y-values that are one unit apart. The unit rate is the difference in the corresponding x-values.”

What is the step by step equation to solve 5 (y + 2/5) = -13
Temka [501]

5( y + 2/5) = -13

Distribute the 5 by multiplying the 5 by each term inside the set of parentheses:

5y + 2 = -13

Subtract 2 from both sides:

5y = -15

Divide both sides by 5:

Y = 3

The answer is y = 3

HELP PLEASEEEEE URGENT
gregori [183]

Answer:

5

Step-by-step explanation:

1) Solve for the slope(m):

(y2-y1) / (x2-x1)

pick any

(-3 - (-5) )/ (1 - 0)

(-3 + 5) / (1 - 0)

2/1 = 2

2) b(intercept) value is found when x = 0:

x = 0, y = -5,

b = y

b = -5

3) Plug it in:

y = mx + b

y = 2x - 5

4) when the value is 5, x = 5:

y = 2x - 5

y = 2(5) - 5

y = 10 -5 = 5

What is the value of the product of -20/48 times 6 in simplified form
KATRIN_1 [288]
-20/48 x 6 =   \frac{-20}{48}    x  \frac{6}{1}

I would cancel out the 6 in the numerator and the 48 in the denominator 
Now I have <u />\frac{-20}{8}  or <u />\frac{-5}{2} reduced.

-5 ÷ 2  = -2 1/2 and that is the answer in simplest form

What is the area of the shape
Radda [10]

Answer:

A= 18

Step-by-step explanation:

To find the height, find the blocks inside the shape that is completely attached (they have to be in a straight vertical line).  In this case, you can see that three vertical blocks in the middle of the shape is completely attached.  That means your height is 3.

To find the width, look at the how many horizontal boxes make up the top.  6 block inside the shape corispond with 6 blocks on top of the shape, so the width is six.

Multiply 6 by 3 to get 18.
