Answer: x=8
Step-by-step explanation:
15*8 = 120 + 20 = 140
140+40 = 180 a perfect line
Answer:
a = 9
Step-by-step explanation:
So in this case you just cross multiply
8 : 12 = 6 : a
6(12) = 8(a)
72 = 8a
Divide both sides by 8
a = 9
Graph A shows a single solution where the two lines cross paths. Graph B shows a case where there are no solutions as the lines will never touch. Graph C is the correct answer as it shows the two lines constantly intercepting each other, creating an infinite number of solutions.
Answer:
x= 1
y= -2
This is the solution, so the answer is D
