Answer:
x=8
Step-by-step explanation:
2.25x=1.5x+6
-1.5x -1.5x
0.75x=6
3/4x=6
x=6*4/3
x=24/3
x=8
The results will always equal a positive

The relationship between y and x is y = 5x + 15.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are the variables, m is the rate of change (slope) and b is the initial value of y (y intercept).
From the table, using point (5, 40) and (25, 140):

The relationship between y and x is y = 5x + 15.

Answer:
2x^2 - 7
we can plug any values of x into this The domain is All Real x.
The graph will be a parabola opening upwards with a minimum value when x = 0 and f(x) will be = -7
so the range is f(x) <= -7 or (-∞, -7]
