Answer:
5) m∠DEF = 18
Step-by-step explanation:
I cant answer the rest because they require a protractor
Answer:
(-3,-8)
Step-by-step explanation:
okay so what we can do here is elimination
we can do this first by multiplying the entire second equation by 2
so then it would become
2(5x-2y=1)
10x-4y=2
now we can add the two equations together which will eliminate y
so
-8x+4y=-8 plus
10x-4y=2 equals
2x=-6
we did that by combining like terms
next we can simplify that
x=-3
now we can plug that into the equation
-8(-3)+4y=-8
simplify
24+4y=-8
4y=-32
y=-8
our answer would be
(-3,-8)
bro i read it wrong that's my bad hold on ill get the right one rq
X=75/17 i did the math and got that answer
We can explicitly find the inverse. If 
is the inverse of 
, then
Solve for the inverse :
Then when x = -6, we have
Alternatively, we can first solve for x such that 
. Then taking the inverse of both sides, 
. (The difference in this method is that we don't compute the inverse for all x.)
We have
