Answer:
x = 3
Step-by-step explanation:
set up proportion based on corresponding sides of similar triangles:
15 / 10 = 15 + x / 12
cross-multiply:
10(15 + x) = 15(12)
150 + 10x = 180
10x = 30
x = 3
Each pizza would be 15 dollars.
Each sandwich would be 8 dollars.
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have two points (2, 0) and (-2, -4). Substitute:
Therefore we have the equation of a line
Put the coordinates of the point (2, 0) to the equation:
<em>subtract 2 from both sides</em>
