Please mark as brainliest. I really need it.
(x,y)=(2,1) where the two lines intercept
so for the first equation you go on the y line and dot -4 then count up 5 times then right 2 times since it’s rise over run
for the second line start at positive 3 on the y line then it’s -1/1 which is up once and left once cause of the negative
Answer:
2x+7/6
Step-by-step explanation:
an normal function would be mapping x to y, since this is the inverse we would map y to x
f(x) and y are the same so I will take f(x) as "y"
1)3x-7/2=y
3y-7/2=x
solve/isolate "y" in 3y-7/2=x to get the value of "y"
3y-7/2=x
add "7/2" to both sides
3y-7/2+7/2=x+7/2
3y=x+7/2
divide both sides by "3"
3y/3=x/3+7/2/3
simplify:
y=2x+7/6
hope this helps!
Answer:
Length of DE is 25.
Step-by-step explanation:
Right, so this is something called midsegment theorem. ΔDBE is similar (but not congruent) to ΔABC because of the angles they share. Since DE is described as a midsegment, this means BE=EC and BD=DA; so ΔDBE is half the size of ΔABC, meaning its side lengths are also half that of the larger triangle.
