Answer:
Only one solution
Step-by-step explanation:
Given that there is a coordinate plane (say xy)
Two lines are given.
One line crosses the y axis at 3 and has a slope of negative 1.
hence equation of I line is y = -x+3
The other line crosses the y axis at 3 and has a slope of two thirds.
So equation is y = 2x/3 +3
Since the two lines lie in the same plane and are having different slopes, they intersect at one point.
Eliminate y to get
-x+3=2x/3+3
Or x=0
y=3
Hence solutionis (0,3) for the system.
you want to be at least 70% of his max of 180
at least would be >=
70% = 0.7
x >= 0.7 x 180
or 180*0.70 = 126 so x>= 126
C is the correct answer
Answer:
x=14
Step-by-step explanation:
to find x you have to isolate it so you divide 3 by both sides and that leaves you with the answer
I think 30c+3d would be the correct answer.

Answer:
2662.50
Step-by-step explanation:
Let s represent her old salary. Then we have ...
0.065s = 162.50
s = 162.50/0.065 = 2500
Then her new monthly salary is ...
new salary = old salary + raise
new salary = 2500 +162.50
new salary = 2662.50
