Answer:
y = 11x
Step-by-step explanation:
We have two points so we can find the slope
(1,11) and (2,22)
m = (y2-y1)/ (x2-x1)
= (22-11)/(2-1)
= 11/1
The slope is 11
We can use the point slope form to get an equation
y-y1 = m(x-x1)
y-11 = 11(x-1)
Distribute the 11
y-11=11x -11
Add 11 to each side
y-11+11 = 11x-11+11
y = 11x
Answer:
x=1/3, x=-2/3
Step-by-step explanation:
9x^2 +6x -3x -2=0
6x and -3x add up to 3x. You need four terms to factor.
Then you factor=
3x(3x+2)-1(3x+2)=0
(3x-1)(3x+2)=0
Then you can make two equations
3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.
3x-1=0
3x=1
x=1/3
3x+2=0
3x=-2
x=-2/3
So your answers are x=1/3, x=-2/3
hope this helps!
The function for x=3 is 1
For the composite function g(f(x)), the function f(x) goes first in terms of evaluation. This is the inner most function. You would read it from right to left in terms of determining the order of evaluation.
