I think what's your trying to say is 419-200? If so it's 219
Answer:
You can't find y in this way
Step-by-step explanation:
You should know the value of x
But you can say
Y=7x
Answer:
7 x = -35
Step-by-step explanation:
Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.
- 7 x = negative 35
- 7 x = 35
7 x = negative 35
7 x = 35
In this problem we need to add the equations below i.e.
11x-3y = -17 and -4x+3y=-18
Adding both equations,
11x-3y+(-4x)+3y = -17+(-18)
7x= -35
or
7 x = negative 35
Hence, the correct option is (c).
<span>The slope of a line is defined as the rate of change on the vertical axis, divided by the rate of change on the horizontal axis, Δy/Δx. So for a horizontal line, the rate of change on the y axis is zero, this means that it's slope will be 0/Δx and for vertical line, x-axis does not change, which make the denominator 0 Δy/0.</span>
