Answer:
A. 1/2x + 6 = 10
D. 3/2x - 4 = 11
Step-by-step explanation:
x = 8
1/2 (8) + 6 = 10 CORRECT
x = 6
1/4 (6) - 1/2 = 2 This is incorrect for the correct answer is 1
x = 12
2/5 (12) + 1/5 = 9 This is incorrect for the correct answer is 5
x = 10
3/2 (10) - 4 = 11 CORRECT
A=pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
A≈353.25 ft^2
y=-3x + 4
Slope intercept form is y=mx+b
m = slope
b = y-intercept
If you look on the graph, you can see that 4 is the point in which it is <em>intercepted </em>on the y-axis, so that is the y-intercept. This means that b is 4.
b=4
y=-3x+4
Answer:
0.3 ? I'm not sure sorry.
F ( x ) = 2 x + 3
g ( x ) = x²
Part 1 : f ( g ( x )) = f ( x² ) = 2 x² + 3
Part 2 : g ( f ( x ) ) = g ( 2 x + 3 ) = ( 2 x + 3 )² = 4 x² + 12 x + 9
Part 3:
Both parts represent the composition of functions. In the first part we are plugging function x² into f ( x ) and in the second part we are plugging
2 x + 3 into g ( x ).
