Answer:
what grade is this
Step-by-step explanation:
I'm very confused is this algebra?
Answer:
B
Step-by-step explanation:
m(slope) = y2 - y1 / x2 - x1
-6 - - 6 / 7 - 3
= 0 / 4 = 0
26 x 72 = 1872
40 + 420 + 12 = 472
1872 - 472 = 1400 (the answer)
You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time.
Solving for x: </span><span>9/x-4/y=8 Mult all 3 terms by xy to eliminate the fractions.
9(xy)/x - 4xy/y = 8xy => 9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y)
then 9y = x [ 4(1+2y) ]
9y
therefore x = ------------
4(1+2y)
Solve for y using a similar approach.

Answer:
c=4
Step-by-step explanation:
–2c = –c − 4
add c to both sides
-1c=-4
divide both sides by -1
c=4
