Answer:
Step-by-step explanation:
1. Replace F(x) with y.
2. Interchange x and y in y = 2x + 1: x = 2y + 1
3. Solve this result for y: 2y = x - 1, or y = (x - 1)/2
4. Replace y with:
-1
F (x):
-1 x - 1
F (x) = -----------

The answer is 8. You just go backward from 9 and swap all the signs. "Divide" is now multiply, "subtract" is now add, "multiply" is now divide
Going left to right:
9 x 6 + 2 / 7
Answer:
The y-intercept is -36.
The answer is C.
Step-by-step explanation:
To find the y-intercept, you should plug in 0 for x.
= -36
The y-intercept is -36.
The answer is C.
Answer:
x= -1, -9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/4x2+5/2x+21/4=3
Step 2: Subtract 3 from both sides.
1/4x2+5/2x+21/4−3=3−3
1/4x2+5/2x+9/4=0
For this equation: a=0.25, b=2.5, c=2.25
0.25x2+2.5x+2.25=0
Step 3: Use quadratic formula with a=0.25, b=2.5, c=2.25.
x=−b±√b2−4ac/2a
x=−(2.5)±√(2.5)2−4(0.25)(2.25)/2(0.25)
x=−2.5±√4/0.5
x=−1,−9
