Answer:
I think is C
Step-by-step explanation:
PLEASE MARK ME AS BRAINLIEST
Using the elimination method, multiply the first equation by 60 and the second one by 30 (least common denominators)
30x-45y=11...(1)
12x+5y=9...(12)
Multiply the second equation by 9, to eliminate y
30x-45y=11
+ 108x+45y=81
———————-
138x=92
x=92/138 (reduce fraction with 46)
x=2/3
Substitute x=2/3 into equation 2
12(2/3x)+5y=9
y=1/5
Therefore, the solution to the system is C. (2/3, 1,5)
Answer:
(1,2)
or
x = 1
y = 2
Step-by-step explanation:
To solve the system of two linear equations by graphing, plot the graphs of both lines (linear equation represents the line).
1. The line with the equation intersects the y-axis at point (0,7) and the x-axis at point . Connect these to points with the straight line.
2. The line with the equation intersects the y-axis at point (0,4) and the x-axis at point . Connect these to points with the straight line.
he point of intersection (1,2) of these two lines is the solution to the system of two linear equations.
Answer:
see below
Step-by-step explanation:
2/m=24
Multiply each side by m
2/m*m =24*m
2 = 24m
Then divide each side by 24
2/24 = 24m/24
1/12 =m
Answer:
The slope would be 4/3 or 1 1/3.
Step-by-step explanation:
When you put the coordinates in the point-slope formula, you will get -5 - (-13) over 7 - 1. The answer becomes 8/6 but if simplified, it becomes 4/3 or 1 1/3 as a mixed fraction.
