Answer:
x = 28
Step-by-step explanation:
Answer:
(4,12)
(-1,-3)
Step-by-step explanation:
x^2 - y = 4
y = 3x
Use substitution. Substitute 3x for y in the first equation
x^2 - (3x) = 4
x^2 -3x =4
Subtract 4 from each side
x^2 -3x -4 = 4-4
x^2 -3x-4 =0
Factor
(x-4) (x+1) =0
Using the zero product property
x-4 =0 x+1 =0
x=4 x=-1
Now to find y for each x solution
x=4
y =3x = 3(4) =12
(4,12)
x=-1
y =3x = 3(-1) =-3
(-1,-3)
Question 1:
These questions are getting harder.
The answer is the second choice because we know that angle TSU and angle RUS are congruent since UR and TS are parallel.
Question 2:
Use that "matching".
The answer is the second choice and the choice above the last choice.
Have an awesome day! :)
