Answer:
42
Step-by-step explanation:
Shanice: 88
Greg: (88 - 4) ÷ 2 = 84 ÷ 2 = 42
Answer:
C. f(5) = 13 and f(-3) = -3
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 3
x = 5
x = -3
<u>Step 2: Evaluate</u>
x = 5
- Substitute: f(5) = 2(5) + 3
- Multiply: f(5) = 10 + 3
- Add: f(5) = 13
x = -3
- Substitute: f(-3) = 2(-3) + 3
- Multiply: f(-3) = -6 + 3
- Add: f(-3) = -3
Answer:
The box must be 3 inches in height
Step-by-step explanation:
In this question, we are concerned about calculating the height of the supplies box.
To be able to get the value for the volume, we need to use the mathematical formula.
Since It is a rectangular prism, the volume V = l * b * h
where l, b and h are the length, breadth and height respectively. Now , it is the measurement of the base that is l * b, hence the base area in this question is 6 * 5 = 30 inches^2
The height of the supply box is thus 90/30 = 3 inches high
Y= 2x +3
First, you find the slope. ( use slope formula)
y2 - y1 / x2 - x1 = m (slope)
Then just put the y-axis in, add or subtract (depends on the sign)
