what is the answer if f(x) = 2x-4 if f(x)= -2
Answer:
x = 1
Step-by-step explanation:
Since we know f(x) = -2, we can replace f(x) with -2 in our function and then solve for x:
[tex]-2 = 2x -4[/tex]
Let's add 4 to both sides.
[tex]2 = 2x[/tex]
And then divide both sides by 2.
[tex]x=1[/tex]
And that's value of x, or the answer to our equation. Hopefully this was helpful... if you have more questions, let me know! :)

IM NOT PLAYING JUST GIMME THE ANSWER!
A rope 63 feet long is cut into two pieces. One of the pieces is three times longer than the other piece. Which system of equations yields the length of the short rope, s, and the long rope, l?
A) s + l = 63 l = 3s
B) s + l = 63 s = 3l
C) s + l = 63(3) l = 3s
D) s + l = 63(3) s = 3l
The system of equations that yields the length of the short rope, s, and the long rope, l will be A. s + l = 63 l = 3s
Based on the information given in the question, the equation to use will be:
l = 3s ...... i
s + l = 63 ...... ii
Substitute equation i into ii
s + l = 63
s + 3s = 63
4s = 63
s = 63/4
s = 15.75
l = 3s = 3 × 15.75 = 47.25
The correct system of equations yields the length of the short rope, s, and the long rope, l will be;
⇒ s + l = 63
And, l = 3s
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A rope 63 feet long is cut into two pieces.
The length of the short rope = s,
And, The long rope = l
Now,
Let the length of the short rope = s,
And, The long rope = l
Here, The length of rope = 63 feet
So, We can formulate;
⇒ s + l = 63
And, One of the pieces is three times longer than the other piece.
So, We can formulate;
⇒ l = 3s
Thus, The correct system of equations yields the length of the short rope, s, and the long rope, l will be;
⇒ s + l = 63
And, l = 3s

They want to remove the decimals.
Since the smaller value has 2 decimal places they need to multiply both by 100
So that 0.15 x 100 = 15.

I need help with this question!
Answer:
y=58
x=32
Step-by-step explanation:
two remote interior angle is congruent, equal, to the exterior angle. so 50+88 is equal to y+86. add the two numbers and set the equations equal to each other. 138=y+86. then subtract 86 from both sides. y=58. knowing that y is 58 we can now solve for x. the interior angles of a triangle always equal 180. 58+90, the right angle, equals 148. 180-148=32 therefor x=32

3) Write an equation relating the minutes, x,
to the number of pages, y.
4) Use the equation in problem #3 to find the number of pages for 72 minutes.
3) y=3.5x
4) 3.5(72) = 252 pages for 72 min.
First we divide 21 by 6 to find the how many pages there is in 1 min. (we got 3.5) then we multiply (3.5) by the number of minutes (72) and we get 252 pages for 72 minutes.
Hope that helped:)
