First we have the following equation:
a - b = 0
We clear one of the variables depending on the other:
a = b
Therefore we have to for the following expression:
a + b
We can substitute one of the variables, obtaining:
a + a = 2a
Equivalently:
b + b = 2b
Answer:
a + b = 2a
or
a + b = 2b

=

Cross multiply
12x=900 Divide both sides by 12.
x=75 hammers to begin with.
Explanation:
Slope-intercept form: → 
m: represents the slope and is constant.
b: represents the y-intercept.
Rise/run.



<u><em>But the slope is -2.</em></u>
Hope this helps!
Thanks!
Answer:
f(x) = -5x - 14
Step-by-step explanation:
this table represent a straight line : y = mx +c
first find m which is the slope
m = (-24 - -19)/(2-1) = -5
then find c
-19 = -5(1) + c , c = -14
thus f(x) = -5x -14
