Answer:
a. (0, -2)
b. (1, -2)
c. (2, -2)
d. (3, -2)
e. (4, -2)
f. The y-value of the coordinate is always -2. The x-value of the coordinate is always what x is stated to equal.
Step-by-step explanation:
Since the linear equation y = -2 doesn't have a slope, it will be shown as a continuous horizontal line along, touching the y-axis at it's -2 unit.
Same could be said with the various x-equations, except they will be shown as continuous vertical lines.

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² - 7x
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 3(-2)² - 7(-2)
- Exponents: f(-2) = 3(4) - 7(-2)
- Multiply: f(-2) = 12 + 14
- Add: f(-2) = 26
Answer: 37
Step-by-step explanation:
The radius is 14, if the diameter is 28. The radius is half of the diameter
Answer:
126 in^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) h
A = 1/2 ( 12+16)*9
A = 1/2 (28) *9
= 126
