X/9 -1=5 X=? 9y+1=7 Y=? 3z/7 + 3=-7 Z=
2 answers:
1.
x/9 -1 = 5
add 1 to both side of the equation
x/9 = 6
multiply both side of the equation by 9
x = 54
2.
9y + 1 = 7
subtract 1 from each side of the equation
9y = 6
divide both side of the equation by 9
y =
divide the numerator and the denominator by 3 in order to simplify your fraction
y =
3.
3z/7 + 3 = -7
subtract 3 from each side of the equation
3z/7 = -10
multiply both side of the equation by 7
3z = -70
divide both side of the equation by 3
z =
There you go! I really hope this helped, if there's anything just let me know! :)

The graph which best represents the new function is a linear function on a coordinate plane as shown in the image below.
<h3>How to determine the graph of the new function?</h3>First of all, we would determine the slope of the linear function as follows:
Slope, m = ⅔.
Multiplying by -4, the new slope is:
Slope = ⅔ × -4
Slope = -8/3 or 2.7.
For the equation of this line, we have:
y - y₁ = m(x - x₁)
y - 0 = -8/3(x - 3)
y - 0 = -8/3x + 8
y = -8/3x + 8
Decreasing the y-value by 1, we have:
y = -8/3x + 8
y = -8/3x + 8 - 1
y = -8/3x + 7
Therefore, we would have a linear function on a coordinate plane as shown in the image attached below.
