A.x = 10
B. x = 9
C.x = 11
D.x = 8
You can find the value of x in the function f(x) = 3x - 7 when f(x) = 20 by isolating x in the equation. This process leads to an answer of x = 9.
To solve this problem, you need to substitute the given function's value f(x)=20 into the equation and solve for x.
So, you have the equation 3x-7=20. In the next step, you add 7 to both sides to isolate 3x on one side, which gives you 3x=27.
Finally, divide both sides by 3 to find the value of x. Doing so, you get x = 27/3, which simplifies to x = 9.
Therefore, when f(x) = 20, the value of x is 9, which matches answer option B.

The answer is : 1/16th
I hope that's help !
Answer:
The Slope is -5/2
Y-intercept is -25
The equation is y=(-5/2)x-25
Step-by-step explanation:
Choose a first point and a second point
Remember points are (x,y)
Use (y₂ - y₁)/(x₂ - x₁)
y-intercept: The initial value of a linear relationship, the place that a linear equation crosses the y axis, represented by the letter b, the point (0,b).
Linear Relationship -the equation that represents a straight line often represented by y=mx+b where m is the slope and b is the y-intercept.
