The slope is 1/3 because in order to get from point (3,1) to (6,2) you need to rise 1 and go over 3
Since 4>1, this represents exponential growth.
Answer is 7.
55+5X=90
5X=90-55
5X=35
X=35/5
X=7
A) Teresa is correct; y=2ˣ grows at an increasingly increasing rate, while the other two grow at a constantly increasing rate. This means y=2ˣ will surpass the other two.
Supreme sold 29 tires. Set it up like this, with Supreme as your x and Prestige as y: 48x + 56y = 2008. This is an equation in terms of money, with x being the number of Supreme tires sold at $48 each and y being the number of Prestige tires sold at $56 each. We know that Prestige sold 11, so sub it for y and do the math: 48x = 2008 - 616; x = 29
