Y=7 because there is no slope and the Y intercept is at 7.
Answer:
The answer is A. AB and AC are congruent
Answer:
x=4
y=2
You can substitute the equations like y=1/2x and -x+y+2.
Answer:
You only have to sort (numbers with numbers and variables with variables) then do the operations (+/-).
Step-by-step explanation:
![5 + 9f - 10 + 5 \\ - 5 + 9f + 5 \\ 0 + 9f \\ 9f](https://tex.z-dn.net/?f=5%20%2B%209f%20-%2010%20%2B%205%20%5C%5C%20%20-%205%20%2B%209f%20%2B%205%20%5C%5C%200%20%2B%209f%20%5C%5C%209f)
Answer:
(g-f) (-1)= sqrt(15)
(f/g)(-1)= 0
(g+f)(2)=sqrt(3)-3
(g*f)(2)=-3*sqrt(3)
Step-by-step explanation:
We have to eval the expressions given in the point indicated.
Lets start by the first equation
(g-f)(-1)= g(-1) - f(-1)=
= ![\sqrt{15}](https://tex.z-dn.net/?f=%5Csqrt%7B15%7D)
Now, lest continue with the others
(f/g)(-1)= f(-1)/g(-1)= (1-1)/sqrt(15)=0
(g+f)(2)=g(2)+f(2)=sqrt(3)-3
(g*f)(2)=g(2)*f(2)=sqrt(3)*(-3)=-3sqrt(3)
