Answer:
A graphing calculator is more accurate than graphing by hand. If the slope and/or y-intercept is a fraction or decimal, it is more difficult to accurately graph by hand.
Step-by-step explanation:
Look at my attachment to see the four functions on the graph.
f --> g . . . . . shift the graph down one unit
f --> h . . . . . shift down 2 units, and double the slope
f --> d . . . . . shift up 2 units, and reduce the slope by half
Answer:
5x + 10y
5*4 + 10*5
20+50 = $70
Step-by-step explanation:
Answer:

General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
12 = 5/2b
<u>Step 2: Solve for </u><em><u>b</u></em>
- Rewrite: 5/2b = 12
- Divide both sides by 5/2: b = 24/5
<u>Step 3: Check</u>
<em>Plug in b to verify it's a solution.</em>
- Substitute: 12 = 5/2(24/5)
- Multiply: 12 = 12
Answer:
-2x = -60
Isolate x and simplify.
2x = 60
x = 30
Straight vertical line through x=30.
