Answer:
Step-by-step explanation:
Subtract x from both sides.
Square both sides.
Subtract x²-6x+9 from both sides.
Factor left side of the equation.
Set factors equal to 0.
Check if the solutions are extraneous or not.
Plug x as 2.
x = 2 works in the equation.
Plug x as 6.
x = 6 does not work in the equation.
Answer:
8 2/3lbs
Step-by-step explanation:
6 1/2×1 1/3=6 3/6+2 1/6
=8 4/6= 8 2/3
The linear function that goes through the points (2,-4) and (-4,2) is:
y = -x + 2.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
A linear function going through the points (2,-4) and (-4,2) would intersect the parabola at these points, hence these points would be the solution for the system of equations.
The slope of the line is:
m = (-4 - 2)/(2 - (-4)) = -1.
The line goes through point (2,-4), that is, when x = 2, y = -4, which we use to find the y-intercept b.
y = -x + b
-4 = -2 + b
b = -2.
Hence the equation is:
y = -x + 2.

Answer : Image 3
Which table shows a function that is decreasing over the interval (−2, 0)?
We look at the interval -2 to 0 on x
In option 1 table , f(x) is 0 then -5 and then becomes 0
It means -2 to -1 , f(x) decreases but from -1 to 0 y values increases
In option 2 table , f(x) is increasing from -15 to -5
In option 3 table, f(x) values goes on decreasing over the interval -2 to 0
So , option 3 table shows a function that is decreasing over the interval (−2, 0)
