Answer:

x+3-12/8

Step-by-step explanation:

h(x)=-3/8x+12

y=h(x) let

y=-3/8x+12

here,

put at x at y and put y at x

x=-3/8y+12

8y=x+3-12

y=x+3-12/8

Answer:

The value of x is 8

The measure of angle A is 42 degrees

A and B are consecutive interior angles

Step-by-step explanation:

Since A and B are consecutive interior angles you combine both equations and have it equal to 180

16x+10+5x+2=180

21x+12=180

21x=168

x=8

Plug 8 into the equation across from A

16(8) +10

128+10

138 degrees

Since angle A is supplementary you do 180-138= 42 degrees

the monthly contract seems pretty good

Step-by-step explanation:

why pay 30 cent or 10 cent per min when you can just pay monthly cause eventually you going to be paying the same amount . hope this helpsssssss. brainliest:)

Answer:

The answer is No.

Step-by-step explanation:

Due to 19.16 - 4 equaling 15.16, it isn't correct. 15.16 doesn't equal 15.02.

Answer:

Thank you ☺️☺️

Lets solve your equation step-by-step

2(x+3)=x-4

Step 1 :Simplify both sides of the equation

2(x+3)=x-4

(2)(x)+(2)(3) =x+-4 (distribute)

2x+6=x+-4

2x+6=x-4

Step 2: Subtract x from both sides

2x+6-x=x-4-x

x+6=-4

Step 3: Subtract 6 from both sides

x+6-6=-4-6

Answer: x=-10

Step-by-step explanation: 2+2 is 4

The correct option is Option C: The function shown on the graph has a greater rate of change and a higher starting point.

The rate of change of function is the change in the value of the function with respect to x value.

rate of change of function f(x)= df(x)/dx= f'(x)

Here the function given in the question is y=2x-5

rate of change of function= f'(x)= df(x)/dx= dy/dx= d(2x-5)/dx= 2

the starting point of the function f is y-intercept of the function.

the y-intercept of the function is the point where the function touches the y-axis which can be calculated by putting x value is equals to 0.

y= 2x-5

⇒y= 2*0-5

⇒y= -5

The starting point of function is -5.

Given the graph has slope = |y-intercept| / |x intercept|

= 4/1 =4

rate of change of graph = slope of graph= 4

similarly, the y-intercept of the function is the point where the function touches the y-axis which can be calculated by putting x value is equals to 0.

The y-intercept of the graph= the starting point of the graph= -5

Therefore the function in the graph has a higher rate of change as well as a higher starting point.

From the above, it is clear that the correct option is Option C: The function shown on the graph has a greater rate of change and a higher starting point.

Answer: {y,x}={2,8}

// Solve equation [2] for the variable  y

 [2]    y = -2x + 18

// Plug this in for variable  y  in equation [1]

  [1]    (-2x+18) - x = -6

  [1]     - 3x = -24

// Solve equation [1] for the variable  x

  [1]    3x = 24

  [1]    x = 8

// By now we know this much :

   y = -2x+18

   x = 8

// Use the  x  value to solve for  y

   y = -2(8)+18 = 2

Solution :

{y,x} = {2,8}

Answer:  x = -7

Step-by-step explanation:

x = -7 will be a vertical line passing through all y values, and perpendicular to y = 5

The attached graph shows the lines and the point.

Step-by-step explanation:

we can proceed to model the cost of Billy's Boat Rental Company

let y be the cost

let x be the number of rentals

y=105+9.5x----1

Also, the cost of Billy's Boat Rental Company

y=14.75------2

the question is "How many times does a person have to rent a boat for the cost to be the same amount at both rental companies"

we have to equate the two cost and solve for x

105+9.5x=14.75

105-14.75+9.5x=0

90.25+9.5x=0

9.5x=-90.25

divide both sides by 9.5 we have

x=-90.25/9.5

x=9.5

Step-by-step explanation:

If you have $65.00 and 1 dvd costs $15.00 that leaves you with $50.00 and each CD costs $12.00 just multiply by 12s until you get to 50 or close so there you can buy 4 CDs and have 2$ left.

Answer:

The correct answer would be 3x/5y

Step-by-step explanation:

You are substracting, and the denominator is the same for both 5x/5y and 2x/5y, so it will remain the same (5y). This only leaves you needing to substract 5x-2x, which equals 3.

5x/5y-2x/5y= 3x/5y

Step-by-step explanation:

Answer:

1) The dependent variable is the monthly charge and the independent variable is the $110 to open the membership.

2)The dependent variable is the monthly charge because it will change depending on how many months you plan to keep your membership.

3)This relationship is linear because it will go up by $30 every month.

4)You could create a graph off of this information because all you would need to do is graph the cost each month.

5)I would need the number of month that I would keep the membership going and the amount that i have already paid.

Answer:

(-4,3)

Step-by-step explanation:

Answer:

P = -4, 3

Step-by-step explanation:

Locate the x-axis (horizontal) location of point P, starting from zero

Point P's x-axis = -4

Now locate the y-axis (vertical) location of point P, starting from zero

Point P's y-axis = 3

Combine the two axes in a coordinate equation.

Point P = (-4, 3)

Note that zero is located at the intersection of the two axes.

Answer: 6.89 per pound (assuming you meant which is the better deal)

Step-by-step explanation:

4x+7(3x-3) = 9-5x (equation)

4x+21x-21 = 9-5x (simplify)

25x-21 = 9-5x (combine like terms)

30x-21 = 9 (add 5x to each side)

30x = 30 (add 21 to each side)

x = 1 (divide each side by 30)
