Answer:
3x^2+14x-2 if you meant f(x)=3x^2+10x and g(x)=4x-2
and I think C was meant to read 3x^2+14x-2
Please correct me if I have mistranslated. Thank you kindly.
Step-by-step explanation:
I kind of wonder if you meant f(x)=3x^2+10x and g(x)=4x-2.
(f+g)(x)=f(x)+g(x)
=(3x^2+10x)+(4x-2)
=3x^2+10x+4x-2
=3x^2+(10x+4x)-2 I paired 10x and 4x together because they are like terms
=3x^2+14x-2
Answer:
Third choice
Step-by-step explanation:
They are asking us to find the inverse of y=5x. To do this you just switch x and y and then remake y the subject of the equation (solve for y.)
y=5x
x=5y (I switch x and y)
x/5=y ( I divided both sides by 5)
Then you just replace y with the f^-1(x) thing
f^-1(x)=x/5
or
f^-1(x)=1/5x
Is there a picture that you can provide with this? I would be glad to try and help.
Answer:
Whats the Question
Step-by-step explanation:
We are given D (7, -3) and D'(2, 5).
SAppy the transformation
D'(x,y) → D(x-5, y+8).
Then
x=7 → x=7-5 = 2
y=-3 → y=-3+8 = 5
Answer: D (x-5, y+8) → D'
