Add 2x to both sides,
3x+9=18
Subtract 9 from both sides. 3x=9
Divide both sides by 3.
x=3
The answer would be 28 square inches because you would multiple the length (4 inches) and the width (7 inches) to each other.
y=2x-0.5
Step-by-step explanation:
Given the expression of Δy in terms of Δx as;
Δy=4/2 Δx
Given y=2.5 and x =1.5 then substituting in the equation above will give;
y-2.5=2(x-1.5)
y-2.5=2x-3
y=2x-3+2.5
y=2x-0.5

Answer:
-8/3
Step-by-step explanation:
To solve for x-intercept, we set y as 0.
0 = 3x + 8
-8 = 3x
-8/3 = x
The x-intercept of the line is -8/3.
