let x is the number

twice a number is 2x

Four more than twice a number: 2x + 4

Four more than twice a number is 8 :

2x +4 = 8

If solve for x then

2x + 4 = 8

subtract 4 to both sides

2x +4 - 4 = 8 -4

Simplify

2x = 4

Divide both sides by 2

2x/2 = 4/2

Simplify

x = 2

The sum of two numbers is 19 . When the second number is subtracted from the first number, the difference is 17 . Find the two

zhenek [66]

Answer:

19 and 2

Step-by-step explanation:

Let x represent the first number and y represents second number

x + y = 19

x - y = 17 add two equations up

2x = 36 divide both sides by 2

x = 19 and since the difference is 17 the other number is 2

One day at 3:00 a.m., the temperature was -13°F in Kodiak, Alaska. At 10:00 a.m., the temperature was 22°F. What was the average

suter [353]

-13 to 0 = 13 degrees changed. 0 to 22 is 22 degrees changed. 13 + 22 = 35 degree change.

10-3 = 7.

So there was a change of 35 degrees across 7 hours

35/7 = 5 degrees per hour.

Graph the parabola 3x^2+6x-24

brilliants [131]

We have the following function:
F (x) = 3x ^ 2 + 6x-24
We observe that it is a quadratic equation.
The graph is therefore a parabola.
Its cut points are:
(-4, 0)
(2, 0)
Answer:
See attached image to see graph of the function
