Answer:
f( g(x)) = 18 *x*x + 6
g( f(x)) = 6xx + 18
Step-by-step explanation:
we want f (g(x)) and g( f(x))
f = 2xx + 6 g = 3x
f( g(x)) = 2 *(3x)*(3x) + 6 = 18 *x*x + 6
g( f(x)) = 3*(2 xx + 6 ) = 6xx + 18
Step-by-step explanation:
gradient/slope = 3
y-intercept
2x - 3y = 4
3y = 2x - 4
y = 2/3x - 4/3
so y-intercept is double -4/3 so... -4/3x2 = -8/3
the equation of the line is
y = 3x - 8/3 or 9x - 3y = 8
Answer:
A system of linear equations is a system made up of two linear equations. To solve the system of equations, you need to find the exact values of x and y that will solve both equations. One good way to do this is to graph each line and see where they intersect.

Answer: The shirt originally cost 125 dollars.
Step-by-step explanation: The shirt on sale is 25% off. So first multiply 25 by 5 and you get 125. So 125 is the originall price. Her final cost is 25 dollars. Last step: 125 divided by 5 equals 25 dollars.
