f(x) = 7x + 13
f(-3) = 7(-3) + 13
f(-3) = -21 + 13
f(-3) = -8
Light travels at 186,000 miles per second. Light takes about 11⁄3 seconds to travel from the earth to the moon. Calculate the distance between the earth and the moon based on the speed of light.
First of all we must multiply the speed of light by the time it takes to travel to the from here to the moon. The quantity is 682,000 miles.

Answer:
x − y = −3
Step-by-step explanation:
To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.
Ax+By=C
Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.
1x+3=y
Move all terms containing variables to the left side of the equation.
Multiply x by 1.
x+3=y
Move y to the left side of the equation because it contains a variable.
x+3−y=0
Move 3 to the right side of the equation because it does not contain a variable.
x−y=−3
