Answer:
x = 2
Step-by-step explanation:
Set the equations equal to each other
x + 2 = -3x + 10
+ 3x + 3x Add 3x to both sides
4x + 2 = 10
- 2 - 2 Subtract 2 from both sides
4x = 8 Divide both sides by 4
x = 2

Answer:
The equation of the line in the slope-intercept form is:
Step-by-step explanation:
The slope-intercept form of the equation of a line is
As y intercept is -8, we have
Since the line is parallel to 
, then it has the same slope.
Let's put this equation in form and find the slope
Thus, the slope is :
Now we can finish the equation of the line in the slope-intercept form
∵ , b = -8
Therefore, the equation of the line in the slope-intercept form is:
This is the concept of proportionality, given that z is directly proportional to x and inversely proportional to y then:
zαx/y
z=(kx)/y
where;
k is the constant of proportionality given by:
k=zy/x
but when x=3 and =6 then z=9.5
therefore:
k=(9.5*6)/3
k=19
hence the formula for z will be:
z=(19x)/y
the value of z when x=8 and y=12 will be:
z=(19*8)/12
z=12 2/3
