Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x + 3
f(-5) is x = -5
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-5) = 4(-5) + 3
- Multiply: f(-5) = -20 + 3
- Add: f(-5) = -17
Answer: y-intercept: (0,-6)
Answer:

3 shirts at 25.99 each : 3 * 25.99 = 77.97
plus sales tax of 5.5% : 77.97 + .055(77.97) = 77.97 + 4.29 = 82.26
A = cross sectional area of the pipe. When the pressure is expressed in terms of the equivalent height of a column of that fluid, as is common with water, the friction loss is expressed as S, the "head loss" per length of pipe, a dimensionless quantity also known as the hydraulic slope.
