A because 1×2 is 2 than 2×2 is 4
Answer:
The price of pretzels in 1975 = $1.80
Step-by-step explanation:
To answer this question we are assuming the steady rate means linear.Let x be the year and y be the price.
We need to find the slope
m = (y2-y1)/(x2-x1)
= (4.80-4.05)/(2015-2005)
=.75/10
= .075
The slope is .075
We can use the point slope form of the equation
y-y1 = m(x-x1)
y-4.80 = .075(x-2015)
Distribute
y - 4.80 = .075x -151.125
Add 4.80 to each side
y - 4.80+4.80 = .075x -151.125+4.80
y = .075 x - 146.325
We want to find out how much pretzels were in 1975. Put in x=1975
y = .075(1975) -146.325
y = 148.125-146.325
y=1.80
Answer:
12 is the y intercept and -3x is the slope
Step-by-step explanation:
Answer:
580742.5, in words: five hundred eighty thousand seven hundred forty-two and a half.
Multiply: 1489 * 390 = 580710
Divide: 65 / 2 = 32.5
Add: 580710+32.5 = 580742.5
