Answer:
7
Step-by-step explanation:
2x-4=10
2x=10+4
2x=14
x=14/2
x=7
1)
-2(3x+4)=-6x-8≠-6x+8
2)
2(-3x+4)=-6x+8
3)
5(x+1)-11x+3=5x+5-11x+3=-6x+8
4)
x+2-7x+6=-6x+8
5)
8-6x=-6x+8
Answer: The expressions 2,3,4 and 5 are equivalents.
Answer:
y = - 4x
Step-by-step explanation:
Here, it is given that the slope of a line is - 4 and the y-intercept is 0.
Now, if the slope of a straight line is m and the y-axis intercept is c, the by slope-intercept form the equation of the straight line is given as
y = mx + c ......... (1)
Therefore, in our case m = - 4 and c = 0 and using equation (1), the equation of the given straight line is
y = - 4x (Answer)
