Answer:
(a) (6, 2)
Step-by-step explanation:
The system of equations has one of them in y= form, so it lends itself to solution by substitution.
__
Using the equation for y to substitute into the first equation, we have ...
2x -y = 10
2x -(-1/2x +5) = 10 . . . . . substitute for y
2x +1/2x -5 = 10 . . . . . eliminate parentheses
5/2x = 15 . . . . . . . . . add 5, collect terms
x = 6 . . . . . . . . . . . multiply by 2/5
Using the equation for y, we have ...
y = -1/2(6) +5 = -3 +5
y = 2
The solution is (x, y) = (6, 2).
Answer:
The value of the x-coordinate is -3.5.
Step-by-step explanation:
To determine the x-coordinate you have to look at how far the point is on the x-axis which is the sideways line of the graph.
Point W is between -3 and -4 on the x-axis which would make the x-coordinate -3.5.
Hope this helps!
It would be 67,437,000,000 since the eight in 67,436,(8)28,104 rounds the 6 up to a 7.
Answer:
7.5 feet and 90 inches
Step-by-step explanation:
you take 2.5 and multiply it by 3 because there are 3 feet in a yard to get 7.5. then take 7.5 and multiply it by 12 to get 90 inches
