The point-slope form of a line is:
y-y1=m(x-x1), where m=slope and (x1,y1) is any point on the line.
y+3=(-1/4)(x-8)
Answer:
x=4
Step-by-step explanation:
Let the cherry pies be c and the pumpkin pies be p:
Shawna: c + 3p = 55
Amanda: 3c + 3p = 69
We want to find the cost of c + p. To do this, the easiest way is to divide the second equation by 3:
(3c + 3p)/3 = 69/3
c + p = 23
Therefore, 1 cherry pie & 1 pumpkin pie cost $23.
Let x be the population in 1950. Now re-rea the problem and translate the English into math language:
12.6 Mil = 1 Mi + 4x
12.6 - 1 = 4x
4x = 11.6
x = 11.6/4
x = 2.9 Mil
