Answer:
Step-by-step explanation:
2x²+8=80
2x²=80-8=72
x²=72/2=36
x=±√36
x=±6
so x=6 is one solution other is x=-6
Two lines that are parallel have the same slope. In its slope-intersect form, we can write the equation of a line with slope m and y-intercept b as:
Step 1
Write the given equation in slope-intercept form and identify its slope m.
Thus:
Step 2
Find the equation with the same slope m = -2. We need to identify which of them has -2 multiplying the variable x.
Answer
From the given options, the only one with the same slope m = -2, therefore parallel to the given line, is:
First, let's identify if it's increasing or decreasing.
Since the graph is going downwards, it's decreasing.
Next, is the graph linear or nonlinear?
This graph is definitely not a line, so it's nonlinear.
Your answer is nonlinear decreasing.
Have an awesome day! :)
<span>1. If (-1, y) lies on the graph of y = 3^(x+1), then y = 3^(-1 + 1) = 3^0 = 1
2. If (x, 1/100) lies on the graph of y = 10^x, then 1/100 = 10^x
10^-2 = 10^x
x = -2
3. If (-1, y) lies on the graph of y = 2^2x, then y = 2^2(-1) = 2^(-2) = 1/4
4. The relationship between the graphs of y = 2^x and y = 2^-x is reflections over the y-axis.
5. If (3, y) lies on the graph of y = -(2x), then y = -2(3) = -6
6. All are not exponential
7. If (-2, y) lies on the graph of y = 4^x, then y = 4^(-2) = 1/4^2 = 1/16
8. If (-3, y) lies on the graph of y = 3^-x, then y = 3^-(-3) = 3^3 = 27
9. If (-3, y) lies on the graph of y = 3^x, then y = 3^(-3) = 1/3^3 = 1/27
10. If (-3, y) lies on the graph of y = (1/2)^x, then y = (1/2)^(-3) = 2^3 = 8</span>
