\\ \sf\longmapsto 3(h-9)+2h=h-27+4h

\\ \sf\longmapsto 3h-27+2h=5h-27

\\ \sf\longmapsto 5h-27=5h-27

\\ \sf\longmapsto 5h-5h=-27+27

\\ \sf\longmapsto 0=0

The expression has no solutions

Answer:

  • h - any real number

Step-by-step explanation:

  • 3 (h−9) + 2h = h − 27 + 4h
  • 3h - 27 + 2h = 5h - 27
  • 5h - 27 = 5h - 27
  • 0 = 0

h = any number

Question 4 i need help on!!
MrMuchimi

Answer:

C  20

Step-by-step explanation:

Set up equations:

Laguna's Truck Rentals

y = 2x + 20

Where x is the number of miles driven and y is the total price

<em>How did we get to this equation?</em>

Well, the company charges $2 for every mile driven. Therefore, by multiplying 2 and x, you will find the price paid per mile. The 20 (which represents $20) is the one-time payment you pay for simply using the service.

Salvatori's Truck Rentals

y = 3x

Where x is the number of miles driven and y is the total price

<em>How did we get to this equation?</em>

For this company, you only pay for how many miles you drive. There isn't a one-time payment like there is for Laguna's Truck Rentals. Therefore, you only need to multiply the price per mile ($3) by the number of miles driven (x).

Set the equations equal to each other:

2x + 20 = 3x

<em>Why would you do this?</em>

We need to set the equations equal to each other because we need to find the point at which the prices are the same. When two things are the same, they are equal. Therefore, we get rid of the y variable (which represents the total price) because we want to find the value of x when the equations are equal to one another.

Solve:

2x + 20 = 3x

Subtract 2x on both sides:

2x + 20 = 3x

-2x           -2x

20 = x

When x is equal to 20, or when the number of miles driven is 20, the total price of the Truck Rental services is the same.

Hope this helps :)

HELP i don’t know what the slope is or how to do this!!!
nadya68 [22]

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

m =  \frac{rise}{run} =  \frac{y2 - y1}{x2 - x1}

Sally says it is possible to draw a triangle with these side length
professor190 [17]

Step-by-step explanation:

The longest side of a triangle cannot be longer than the sum of the two shorter sides. So if the 5cm and 12cm sides are the shorter sides, the third one cannot be longer than the 17cm. ... So 12cm is not longer than 5cm plus the length of the third side, and therefore the missing side cannot be shorter than 7cm.
