1. Substitute
<span><span>−2x+3=13x−4</span><span>
2. Solve for x
x = 7/15

3. Substitute x into the equation
y = 31/15

The answer is

Since both the expressions in x are equal to y then they are equal to each other, so

-2x + 3 = 13x - 4

-15x + 3 = -4

-15x = -7 

x = 7/15

and y = -2(7/15) + 3 =  31/15  = 2 1/15

I need help writing an equation with x,y for the table.
Karolina [17]

Answer:

Number 5 is ' 2(x) + 1 = y '

I dont know how to solve number 6.

Step-by-step explanation:

you take your x variables and compare them to each other and compare them to the y variables. each x variable goes into the y variable 2 times. thats where the 2(x) comes from. then once yiu do that for all your x variables, you must look to see what they have in common. in this case all of them are one digit less than the y value. so you add that to your equation and it become ' 2(x) + 1 = y '

Mazyrski [523]

Answer:

a) The rate of change is 3.5

b) The rate of change represents the price of a single cookie. $3.5

Step-by-step explanation:

a) To determine the rate of change along the graph, select a pair on the graph as;

(2,7)  and (8,28)

Rate of change, m= change in y/change in x

m=28-7/8-2 = 21/6 =7/2 = 3.5

b)

The equation of the relationship can be written as;

y=3.5 x + 0  where y is the amount collected and x is the number of cookies sold.

The slope here represents the price per cookie in $, $3.5
