Answer:
any # where -2<=x<7
Step-by-step explanation:
(x-7) would be negative and (x+3) positive, resulting in f(x) being negative.
Step-by-step explanation:
2 days= 24 hours in 1 day, so multiply that by 2 to get 48 hours total.
Now find the amount of time the wild fire doubles by dividing 48 total hours by 6. So it will double 8 times
The size was 1 acre. Let's multiply by 2, 8 times
1
2
4
8
16
32
64
128
The fire will cover 128 acres in two days.
203---- 100%
x-----148%
x=203*148/100=203*1.48=300.44
30$ originally - 21$ paid = 9$ discount
> divide the discount by the original price, multiply by 100 to get the percent decrease.
100 x (9$ / 30$) = 30% discount
> So the shoes where on sale for 30% off the original price.
for the equation:
100 x (30-21)/30 = % decrease
