Answer:
y=-8
Step-by-step explanation:
First, rewrite the equation in slope-intercept form:
Now just look at the slope-intercept form and your y-intercept is -8, and your slope is .
If you don't know what slope-intercept form is it is y=mx+b where m is your slope and b is your y-intercept.
Hope this helps! :)
The value of is
Explanation:
Given that the function is
We need to determine the value of
<u>The value of Opposite side of the triangle:</u>
The formula for is given by
The value of opposite side can be determined using the formula,
Thus, the value of opposite side is 4
<u>The value of </u><u>:</u>
The formula for is given by
Substituting the values, we have,
Thus, the value of is
<u>The value of </u><u>:</u>
The formula for is given by
Substituting the values, we have,
Thus, the value of is
Hence, the value of is
We want to solve
√(2x+4) - √(x) = 2
Write equation as
√(2x+4) = √x + 2
Square each side.
2x + 4 = x + 4√x + 4
x = 4√x
x - 4√x = 0
√x (√x - 4) = 0
Either
√x = 0 => x = 0
or
√x = 4 => x = 16
Test for extraneous solutions.
When x = 0:
√(2x+4) - √x = 2 (Correct)
When x = 16:
√(2x+4) - √x = √(36) - √(16) = 6 - 4 = 2 (Correct)
A plot of f(x) = √(2x+4) - √x - 2 = 0 confirms hat the solutions are correct.
Answer: B. x = 0 and x = 16.
√(2x+4) - √(x) = 2
Write equation as
√(2x+4) = √x + 2
Square each side.
2x + 4 = x + 4√x + 4
x = 4√x
x - 4√x = 0
√x (√x - 4) = 0
Either
√x = 0 => x = 0
or
√x = 4 => x = 16
Test for extraneous solutions.
When x = 0:
√(2x+4) - √x = 2 (Correct)
When x = 16:
√(2x+4) - √x = √(36) - √(16) = 6 - 4 = 2 (Correct)
A plot of f(x) = √(2x+4) - √x - 2 = 0 confirms hat the solutions are correct.
Answer: B. x = 0 and x = 16.
