The x-intercept is -6
Step-by-step explanation:
In order to find the x-intercept, we put y = 0 and to find the y-intercept we put x = 0
In the given method, x is put equal to zero instead of y as x-intercept had to be found.
Given equation is:
Dividing both sides by -2
The x-intercept is -6

B and D because it doesnt matter how you write the equation you still get the same answer,
don't forget to rate my answer 5 stars and thank me
Answer:
x = 2±sqrt(11)
Step-by-step explanation:
x^2 -4x - 7 =0
Add 7 to each side
x^2 -4x -7+7 =0+7
x^2 -4x =7
To complete the square take the coefficient of the x term and divide by 2 and then square it. Add it to both sides
-4 /2 = -2 then square
(-2)^2 = 4
Add 4 to both sides
x^2 -4x+4 =7+4
x^2 -4x+4 = 11
Factor the left side into (x-b/2)^2
(x-2)^2 =11
Take the square root of each side
sqrt((x-2)^2) =±sqrt(11)
x-2 = ±sqrt(11)
Add to to each side
x-2+2 = 2±sqrt(11)
x = 2±sqrt(11)
Hope this helps but I think the answer could be : 157+25m=50+60m
