Answer:

y = 5x+ 19

Step-by-step explanation:

For parallel lines, the slopes are the same.

y= mx+c

By substituting the values, we get

9=5(-2)+c

19= c

Thus, the equation is y = 5x+19

Answer:

x>3 but x<5 so x=4

4-3=1

4+2=6

4-5=-1

but |-1|=1

Luis hizo un viaje en el coche en el cual consumio 20 l de gasolina. el trayecto lo hizo en dos etapas en la primera consumio 2/

algol13

Answer: $24\ liters$

Step-by-step explanation:

Let be "x" the amount of gasoline in liters that the car's tank had at the beginning of the trip.

1. In the first part of the trip the amount of gasoline the car used can be expressed as:

$\frac{2}{3}x$

2. After the first part of the trip, the remaining was:

$x-\frac{2}{3}x=\frac{1}{3}x$

3. In the second part of the trip the car used $\frac{1}{2}$ of the remaining. This is:

$(\frac{1}{3}x)(\frac{1}{2})=\frac{1}{6}x$

4. The total amount ot gasoline used in this trip was 20 liters.

5. Then, with this information, you can write the following equation:

$\frac{2}{3}x+\frac{1}{6}x=20$

6. Finally, you must solve for "x" in order to find its value. This is:

$\frac{2}{3}x+\frac{1}{6}x=20\\\\\frac{5}{6}x=20\\\\5x=120\\\\x=24$

IS IT CORRECT ILL MARK YOU BRAINLIST

Andrews [41]

Step-by-step explanation:

1 is wrong, because if it says the sum of 5 times the number m and 12 that means its 5(m+12)=27

because its the sum and then 5 times that

2. You got the right answer, its five times x squared plus 2 is 22

The volume of a rectangular prism is 420 cubic centimeters. The length, L, is 6 centimeters and the width, W, is 14 centimeters.

Harman [31]

Answer:

5 centimeters

Step-by-step explanation:

We know the equation to find volume is V = B x h, where B is the base of the prism. (It is also known as the simple V = l x w x h.)

No matter what equation you use, you will end up with V = l x w x h, since the base of a rectangular prism is length x width. So, we're going to plug in our known information to get 420 = 6 x 14 x h.

Then, we're going to multiply 6 x 14 to get 84. Now we have 420 = 84 x h. To isolate the h (in order to find what it is), we must divide both sides by 84.

420/84 = 5, so whats left of the equation is 5 = h, meaning your height is 5 centimeters.
