Answer:
the answer is 80
Step-by-step explanation:
QR=ST: 7x+3=5x+25
2x=22
x=11
7(11)+3=80 5(11)+25=80
Answer:
An hour
Step-by-step explanation:
assuming the speed adds the half hour, three times the speed would take out an hour and a half (going by half hour marks)
Step-by-step explanation:
Clearly, there is a common difference between the monthly employment rates:
8.7% - 8.9% = -0.2%
8.5% - 8.7% = -0.2%
8.3% - 8.5% = -0.2%
a) So, for every month x, the percentage will go down 0.2%, starting at 8.9%. So, we can make this equation:
y = -0.2x + 9.1, where x = 1 would be October 2011.
January 2013 is 16 months after October 2011, so:
y = -0.2(16) + 9.1
y = 5.9%
b) To find when the unemployment rate will be zero, we set the equation equal to zero:
0 = -0.2x + 9.1
-0.2x = -9.1
x = 45.5 months
So, rounding up, the U.S. would reach a zero unemployment rate in 46 months or around September 2014? Not completely sure.
Part A) 70 and then 700
Part B) 10
Answer:
B, C, and D
Step-by-step explanation:
The solution is the point where the two lines are touching, as they will only meet once in their infinite length.
The x value is the location on the x-axis where that one solution will meet. in this case, the x value is hard to see, but it is in-between 3 and 4 according to the graph making B, true.
The y value is in-between -1 and -2 if you move the solution point to the left a lot which makes C, true.
We know that the x value is between 3 and 4 of which are both positive which makes D true.
