The equation for the graph above is y=x+0
<span>9a + -3(2a + -4) = 15
Reorder the terms:
9a + -3(-4 + 2a) = 15
9a + (-4 * -3 + 2a * -3) = 15
9a + (12 + -6a) = 15
Reorder the terms:
12 + 9a + -6a = 15
Combine like terms: 9a + -6a = 3a
12 + 3a = 15
Solving
12 + 3a = 15
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 3a = 15 + -12
Combine like terms: 12 + -12 = 0
0 + 3a = 15 + -12
3a = 15 + -12
Combine like terms: 15 + -12 = 3
3a = 3
Divide each side by '3'.
a = 1
Simplifying
a = 1</span>
Its D
Because the rate of change is 1.5 and 1.5x10 is 15
Answer:
Remainder = 27
Step-by-step explanation:
We can use the Remainder Theorem here. This says that the remainder when f(x) is divided by x - a is f(a).
So here f(-1) will give us the remainder:-
f(-1) = 4(-1)^2 - 7(-1) + 16
= 4 + 7 + 16
= 27
If we did the long division we'd get the alternative form
4x - 11 + 27/(x + 1).
The graph of the two given system of inequalities y > 2x - 5

<h3>How to graph Inequalities?</h3>
We are given two inequalities;
y > 2x - 5
y < -3x
The graph that represents the 2 inequalities has been attached and from the graph, we see that;
- The slope of the dotted line is negative
- The x- intercept of the dotted line is the point (0,0)
- The y- intercept of the dotted line is the point (0,0)
The solution of the system of inequalities is the shaded pink area between the two dotted lines.
