Answer:
Step-by-step explanation:
The Midpoint formula is
where all of those x's and y's come from the coordinates of points L and M. Filling in:
First multiply 2x - 5 by 3 amd will open the brackets
3(2x-5)-4=33
6x - 15 - 4 = 33
6x - 19 = 33
Take -19 to other side and its sign will be become +
6x = 33 + 19
6x = 52
x = 8.6
Step-by-step explanation:
Points are (8,5) and (-12,-9)
The equation of a line passing through two points is given by :
or
But he writes the equation 7x – 10y = 3 which is not matching with the one we have calculated. It means that model calculated by Devon is not good.
Answer:
i think it's
x is greater than or equal to -8
Step-by-step explanation:
Answer:
The solution of the given system of equations is (-6.667,7.667).
Step-by-step explanation:
The given equations are
...(1)
....(2)
put x=0 to find the y-intercept.
Therefore y-intercept of equation (1) is (0,1).
Therefore y-intercept of equation (2) is (0,-19).
put y=0 to find the y-intercept.
Therefore x-intercept of equation (1) is (1,0).
put y=0 to find the y-intercept.
Therefore x-intercept of equation (1) is (-4.75,0).
Draw the graph of both lines by joining their x and y-intercept.
From the graph it is noticed that both the line intersect each other at (-6.667,7.667).
Therefore solution of the given system of equations is (-6.667,7.667).
