Answer:
C. Parallel because the slopes are the same
Step-by-step explanation:
The slope of line AB is 28/14 when divide both by 14 you get 2/1 or in other words 2.
For line CD The slope is 4/2 which is the same as 2. Both the lines have the slope of 2 so that means they are parallel.
Hope that helps and have a great day!
Answer:
8
Step-by-step explanation:
77+50=127
180-127=53
7x-3=53
7x=53+3
7x=56
x=56/7
x=8
To obtain the function for g(x), multiply all of f(x) by 8
G(x) = 8*f(x)
G(x) = 8*(1/x)
G(x) = 8/x
The final answer is choice B
Answer:
-3/2
(2x-14)/3
(-2,-6)
Step-by-step explanation:
I solved the first one for you already ( -3/2)
To make a line perpindicular to another line they need to intersect at a 90 degree angle. To do this the slope of the lines have to be the negative reciprical (take the fraction, flip it, and apply a negative sign to it)
If you do this to -3/2 you get 2/3
If we follow our y=mx+b equation from before we (so far) have
2/3x+b=y
which means that we just need to solve for b
We also know that it crosses the point (7,0) which means that if we plug in 7 for x and 0 for y we can solve for b
we have
(2/3)*7+b=0
Solve for B
14/3+b=0
b= -14/3
Which means our equation looks like this
(2x-14)/3
our two equations look like this
(-3/2)x-9
(2x-14)/3
We need to find where their coordinates are the same (where they intersect)
We can do this by setting them equal to each other and then solving for x
we have
(-3/2)x-9=(2x-14)/3
solve for x
-4.5x-27=2x-14
-13= 6.5x
x= -2
Now that we know what x equals we can plug this into any of our two beginning equations
(-3/2)*-2-9=y
3-9=y
-6=y
Which means our coordinates are (-2,-6)

The exact answer is 183,617,760. Rounding to the nearest convenient numbers, which would make it 5,750,000 x 30, the estimated answer would be 172,500,000
