Just add the two equations together.
2b = 18
b = 18/2
b = 9
9 = k + 10
9 - 10 = k
k = - 1
Answer:
its the 1st one
Step-by-step explanation:
they need to know what the Total
Answer:
The second option you listed: x + y = 4 gives the same line as H, and therefore renders infinite number of solutions (as many as every point on the line)
Step-by-step explanation:
We need to look for the equation that exactly matches the given one :
2 x + 2 y = 8
notice dividing both sides of this equation by "2" we get:
x + y = 4
SO this equation represents exactly the same line as 2 x + 2 y = 8 does, and therefore their graphs overlap completely
3(w+3)^2 would be your answer.
40% of 400 would be 160.
40% is 0.4
so
0.4*400 = 160
to prove my work
400/160 = 0.4 = 40%
