Answer:

-7

Step-by-step explanation:

To find x, substitute the values and solve.

R = 2x + 9y

It becomes:

2x  + 27 = 13

Rearrange and solve

2x = -14

x = -7

Hope this helps

Answer:

x=-7

Step-by-step explanation:

We are given the expression:

R=2x +9y

We want to find x when R=13 and y=3. Therefore, we must substitute the numbers in for the variables.

13=2x+9(3)

Multiply 9 and 3.

13=2x+27

Now we must solve for x by isolating x on one side of the equation.

27 is being added to 2x. The inverse of addition is subtraction, so subtract 27 from both sides.

13-27=2x+27-27

13-27=2x

-14=2x

x is being multiplied by 2. The inverse of multiplication is division, so divide both sides by 2.

-14/2=2x/2

-14/2=x

-7=x

x=-7

A linear function h models a relationship in which the dependent variable decreases 2 units for every 3 units the independent va
ratelena [41]

Answer:

Slope=-2/3,  y-intercept=2, x-intercept=3

Step-by-step explanation:

Let the independent variable be x and dependent variable be y

y=h(x)

h is a linear function so it is represented in the general form of y=mx+c where

m is slope and c is the y-intercept.


Given "the dependent variable decreases 2 units for every 3 units the independent variable increases."

When x increases by 3, y decreases by 2

So the slope = rate of change of y / rate of change of x = -2/3


Given h(0)=2, h(0)=m(0)+c=2

c=2


Combining slope and y-intercept, y=-2/3*x+2

x-intercept is when y=0

0=-2/3*x+2

2/3*x=2

x=2*3/2=3

x-intercept=3
