Answer:
Infinite: 2x+7=2+7
One solution= 2x-5= 10
No solution= 2x+7=2x-6
Step-by-step explanation:
Answer:
x=-17/5
Step-by-step explanation:
1. Simplify -6x-3x+4+4x−6x−3x+4+4x to -5x+4−5x+4.
21=−5x+4
2. Subtract 44 from both sides.
21−4=−5x
3. Simplify 21-4 to 17.
17=-5x
4. Divided both sides by -5.
-17/5=x
5. Switch sides.
x=-17/5
Hope this helps.
The inverse function of
is
<h3>How to determine the inverse function?</h3>
The function is given as:

Rewrite as;

Swap the positions of x and y

Multiply through by -2

Square both sides
4x^2 = y + 3
Subtract 3 from both sides
y = 4x^2 - 3
Express as an inverse function

Hence, the inverse function of
is
