Answer:
a) $2.40
b) $16.80
c) y = -2.40x +16.80
Step-by-step explanation:
a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4
Dylan spends $2.40 at lunch every day.
__
b. The y-intercept can be found from the formula ...
b = y1 -m(x1)
b = 12 -(-2.40)(2) = 16.80
Dylan's dad gives him $16.80 at the beginning of each week.
__
c. The slope-intercept equation is ...
y = mx + b
y = -2.40x +16.80
Answer:
D. 25%
Step-by-step explanation:
f(x) = 2 * (1.25)^x
This is in the form
y = a b^x
where b is 1 plus the growth rate
b = 1.25 = 1+growth rate
1.25 = 1 + growth rate
.25 = growth rate
25% = growth rate
