Hope this helps a little.
Answer:
-1
Step-by-step explanation:
4u-5v=23
-2(2u+4v=16) We multiply by -2 here to destroy u's.
4u-5v=23
-4u-8v=16 we addition both processes
-13v=39 so, v=-3
4u-5(-3)=23, 4u=8 so, u=2
u+v= -3+2= -1
Answer:
x = -1 or x = -11
Step-by-step explanation:
f(x)= 2|x+6|-4
2|x+6|-4 = 6
2|x+6| = 6+4
2|x+6|=10
|x+6| = 10/2
|x+6| = 5
x+6 = ±5
x = ±5 - 6
x = -1 or x = -11
Hey there!
Complementary angles add up to 90 degrees.
We are given
An angle of 79 degrees
and we're asked to find the complement of the angle.
So let's set up an equation:
79+x=90
where x=the unknown angle
Subtract 79 from both sides:
79-79+x=90-79
x=11
Hence, the measure of the unknown angle is

Hope everything is clear.
Let me know if you have any questions!

From googling linear pair you we now that both angles add to 180.
2x + (2y - 10) = 180
You are missing out information since there are two unknowns, x and y. To solve two unknowns we need to equations. If you would like to comment what the other equation could be i.e. there could be another 'linear pair' rule that I don't know about - which is likely - I'd reply and solve it better for you.
