Answer:
(x - 10)(x + 10)
Step-by-step explanation:
x^2 - 100
= x^2 - 10^2
= (x - 10)(x + 10)
Answer:
y < 1/2x - 3
Step-by-step explanation:
You can write the inequality equation for the graph using the form y = mx + b. The inequality line has a y-intercept at (0,-3). This means b = -3. It also has a slope of 1/2 since the line moves up 1 and over 2 to the next point on the line.
This means the lines equation is y = 1/2x - 3. But since this is an inequality, you must use an inequality sign. Since the line is dashed it is not equal to. Your options are < and >. Use the point (0,0) to test which sign is appropriate.
y < 1/2x - 3 y > 1/2x - 3
0 < 1/2(0) - 3 0 > 1/2(0) - 3
0 < -3 0 > -3
The answer is y < 1/2x - 3 since (0,0) doesn't make it true and (0,0) is not shaded in the graph. This means it is not a solution.
69/100 is not correct because 69 cannot be simplified into 6 if 100 is being factored by 10s
The data in the table represents a <span>C. exponential function. In an exponential function, as x-values increase, y-values get greater and greater. The y-values increase more rapidly as x-values increase linearly.</span>
