Answer:
f (g(x)) = 12x + 8
g(f(x)) = 12x + 48
Step-by-step explanation:
These are composition of functions.
(Unless I am reading your notation wrong) Are the functions multiplying eachother? Is the F actually a lower case f ?
Simply do some substitutions.
f (g(x)) = 2 ( 6x) + 8 = 12x + 8
g (f (x) ) = 6 (2x + 8) = 12x + 48
A^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
find the square root of 400
c = 20 miles
Answer:
-6 is the y intercept.
the number added or subtracted from the x in the slope intercept form is always the y intercept
Step-by-step explanation:
plz mark me brainliest
Slope-intercept form is:
y = mx + b
"m" being the slope, "b" being the y-intercept(when x = 0)
You first isolate the "y" in the given equation.
y - 2 = 3(x + 7) Multiply the 3 into (x + 7)
y - 2 = 3x + 21 Add 2 on both sides to get "y" by itself
y = 3x + 23
For the equation of the line to be perpendicular to the given equation, the slope has to be the opposite(you flip the sign and the number of the given slope)
For example:
slope = -2
the perpendicular line's slope = 1/2(positive)
slope = 4/5
the perpendicular line's slope = -5/4(negative)
The given slope is 3 or , when you flip the sign and the number, the perpendicular line's slope is
Now you need to find b, to do so you plug in the point (4,2) into the equation
Add 4/3 on both sides
Make the denominators the same
Your equation is:
