If 3 is added to twice a number, the result is 17. Find the number
Crank

Answer:

7

Step-by-step explanation:

The text of this expression is:

"If 3 is added to twice a number, the result is 17. Find the number"

Let's call x the number we want to find.

Twice the number is equal to

2x

So, if we add 3 to 2x, we get

3+2x

And we know that this is equal to 17:

3+2x=17

Now we can solve the equation to find x: first, we subtract 3 from both sides

3+2x-3=17-3\\2x=14

Now we divide both sides by 2:

\frac{2x}{2}=\frac{14}{2}\\x=7

The lines graphed below are parallel. The slope of the red line is -4/3. What is the slope of the green line?
miss Akunina [59]
I believe the correct answer from the choices listed above is option C. The slope of the green line would be -4/3. Parallel lines <span> are </span>lines<span> in a plane which do not meet; that is, two </span>lines<span> in a plane that do not intersect or touch each other at any point. These lines should have equal slopes. Hope this answers the question.</span>

Solve algebraically: <br> Y = x^2 + 5x - 17 <br> Y = x - 5
Ksenya-84 [330]

Answer:

2

Step-by-step explanation:

What you could do is fill in 2 for the equation and y would equal -3 so for the first one it's like

y= 2^2 + 5(2) -17

y= 4 + 10 - 17 which turns into y= -3

In the second y it would be something like

y= 2 - 5 which would equal y= -3

so x=2
