It’s the second one! I’m 100% sure lol it’s easy
First, make sure that all the variables are in one side. The first equation is gonna be x-y=3
Second, we are going to eliminate the y because it is much easier, but you can also eliminate the x
We have to add both equation because the y in the first equation is negative and in the second equation it’s positive.
We are left with 3x=9
Therefore, x=3
Last, substitute x= 3 in one of the equations
Y=6
P.O.I is (3,6)
Answer:
11.7
Step-by-step explanation:
3(2+q)+15
First you distribute 3 with 2 and q
(3)(2)+(3q)+15
And that gives you 6+3q+15
Next you combine like terms
6+3q+15
(3q)+(6+15) leave 3q the way it is and then add 6+15
And the answer is 3q+21
Answer:
x=17
Step-by-step explanation:
There are two congruent angles so we can double the given values and set that equal to 360. After setting that equal to 360 you find that x is equal to 17, then you plug that into the original equations and get your angles
