f(g(x)) You plug in g(x) for x
f(x) = 2x + 3
f(g(x)) = 2(g(x)) + 3
f(g(x)) = 2(4x - 5) + 3
f(g(x)) = 8x - 10 + 3
f(g(x)) = 8x - 7
g(f(x)) You plug in f(x) for x
g(x) = 4x - 5
g(f(x)) = 4(f(x)) - 5
g(f(x)) = 4(2x + 3) - 5
g(f(x)) = 8x + 12 - 5
g(f(x)) = 8x + 7
Step-by-step explanation:
What is 40% of 400?
- Convert the problem to an equation using the percentage formula: P% * X = Y
- P is 40%, X is 400, so the equation is 40% * 400 = Y
- Convert 40% to a decimal by removing the percent sign and dividing by 100:40/100 = 0.4
- Substitute 0.10 for 10% in the equation: 40% * 400 = Y becomes 0.4 * 400 = Y
- Do the math: 0.4 * 400 = 160
- Y = 160
- So 10% of 150 is 160
- Double check your answer with the original question: What is 40% of 400? Multiply 0.4 * 400 = 160
Answer:
Option C) $10.40
Step-by-step explanation:
Initial hourly wage = 8 $
raise = 30%
therefore, final hourly wage = (30/100*8) + 8
= 2.4 + 8 = 10.4$
Answer:
y = -3x + 18
Step-by-step explanation:
The slope intercept form of a line is expressed as y = mx+c
m is the slope
b is the intercept
Get the slope
Given the equation of a line 9x + 3y = 6
Rewrite
3y = -9x + 6
y = -9x/3 + 6/3
y = -3x + 2
Hence the slope of the line is -3
Get the y-intercept
Substitute m = -3 and (5,3) into y = mx+b
3 = -3(5) + b
3 = -15 + b
3 + 15 = b
18 = b
b = 18
Get the required equation
y = mx+b
y = -3x + 18
This gives the required equation
There is 94.11 meters in 100 yards how I got the answer is because I know that there is 0.9144 in 1 yard. I hope this helps and someone deleted my response so that is why I am responding again.!!!
