Rewrite the given y – 8 = 1/2(x – 4), replacing "y" with "f(x)."
Then f(x) – 8 = 1/2(x – 4)
Multiply all 3 terms by 2 to eliminate the fraction (1/2):
2f(x) = 16 + x - 4
Combine like terms: 2f(x) = x + 12
x + 12
Divide both sides by 2: f(x) = -----------
2
Note that this is equivalent to f(x) = (1/2)x + 6. Important: Use parentheses as indicated.
Answer:
-94
Step-by-step explanation:
t² + 21t - 56
(-2)² + 21(-2) - 56
4 - 42 - 56
-38 - 56
-94
Best of Luck!
9) pi/3 = 180 /3 = 60⁰
the other angle = 90-60=30⁰
10) 2pi/9 = 360/9 = 40⁰
the other angle = 90+40=130⁰
11) arc length = 2pi * r * (θ/360)
= 2pi * 16 * (270/360)
= 75.4 km
12)arc length = 2pi * r * (θ/360)
3 * 180/4 = 135⁰
135/360 =0.375
2pi * 6 * 0.375 =14.13 in
13) arc length = 2pi * r * (θ/360)
= 9 *2pi *(255/360) =40.05 mi
14)arc length = 2pi * r * (θ/360)
=23.56 mi
Just take away a zero so it'll be 170000 kilometers :)) hope I helped!
