Answer:

Step-by-step explanation:
In this case, the <em>y-intercept</em><em> </em>and <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] are given to us, so just put it in Slope-Intercept Form:

If you want it in <em>Standard Form</em>:
y = 4x - 21
- 4x - 4x

Answer:
2x² + 6
Step-by-step explanation:
f(g(x)) = 2(g(x))
= 2(x² + 3)
= 2x² + 6
Answer:
2.4 cm
Step-by-step explanation:
The formula we would use
S = rθ
Where S = Arc length
θ = central angle in radians
r = radius of the circle or length of the radius.
From the question, we can see that if
If C = a point on circle A
The Segment BC = The arc length of the circle = 12cm
∠BAC = central angle in radians = 5 radians.
Since, S = rθ,
Length of the radius = S/θ
= 12cm/5 radians
Length of the radius = 2.4 cm
Answer:
-8/3
Step-by-step explanation:
To solve for x-intercept, we set y as 0.
0 = 3x + 8
-8 = 3x
-8/3 = x
The x-intercept of the line is -8/3.
