Answer:
The x-intercept is -7/5.
Step-by-step explanation:
Firstly, you must know what is intercept<em>.</em><em> </em><em>I</em><em>n</em><em>t</em><em>e</em><em>r</em><em>c</em><em>e</em><em>p</em><em>t</em> is the line where it touches the axis. When a line touches the one axis, the other axis <em>m</em><em>u</em><em>s</em><em>t</em><em> </em>be zero. So in this question, it given to us to find the x-intercept which means that y coordinate is zero. We have to let y equals to zero and solve for the value of x :
Let y = 0,
5x - y = -7
5x - 0 = -7
5x = -7
x = -7/5(improper fraction) or -1 2/5(mixed no.)

Answer:
The answer is D. 14
Step-by-step explanation:
If you were to plug in 14 for x, it would look something like this:
=
Solve 14-4
=
if you were to multiply 5 and 7 by 2, you would get
.
This makes the equation true, because
10/14 does equal itself (10/14)
