Answer:
y = 1/2x + 3
Step-by-step explanation:
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = 1/2x + b
2 = 1/2(-2) + b
2 = -1 + b
3 = b
y = 1/2x + 3
Best of Luck!

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -4x² + 6x - 4
f(5) is x = 5
<u>Step 2: Evaluate</u>
- Substitute: f(5) = -4(5)² + 6(5) - 4
- Exponents: f(5) = -4(25) + 6(5) - 4
- Multiply: f(5) = -100 + 30 - 4
- Add: f(5) = -70 - 4
- Subtract: f(5) = -74
Answer:
She has to cut another piece = 7.75 inches
Total length = 4x + 7.75
This is what y represent, so
y = 4x + 7.75
The graph of the equation is continuous
Answer: x = 1
Step-by-step explanation:
substitute 1 for x
1/2(10(1)+6) = -2(1)+10
1/2(10+6) = -2+10
5+3 = -2+10
8=8
