Step-by-step explanation:
you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.
if yes, it was a solution, and if just only one is false, then it was not a solution.
(3, -2) in
y + 4x = 10
5x - y = 13
so,
-2 + 4×3 = 10
-2 + 12 = 10
10 = 10 true
5×3 - (-2) = 13
15 + 2 = 13
17 = 13 false
so, it was NOT a solution.
Answer: 2.625
Step-by-step explanation:
All you have to do is divide 5 by 8 which gives you .625 and then you put the 2 in front of the decimal amd you get your answer.
Answer:
Step-by-step explanation:
base*hight
-59 = -(b − -55)
Pretend that there is a -1 in front of the bracket.
-59= -1(b--55)
Multiply the bracket by -1
-59= -1(b)-1(--55)
-59= -b-55
Move -55 to the other side. Sign changes from -55 to 55
-59+55= -b-55+55
-59+55= -b
-4= -b
Multiply by -1
-4(-1)= -b(-1)
4= b
Answer: b= 4
