Answer:
1.17
Step-by-step explanation:
5-(2.18+1.65)
The answer is the first option: it has the same domain as the function f(x) = - √(-x).
The domain is the set of x-values for which the function is defined.
The square root function is defined only for zero and positve values.
- x is positive when x negative.
So the domain for - √(-x) and √(-x) are the same: x less than or equal to zero.
Step-by-step explanation:
to compare day 1 with day 2 :
100% = 8
1% = 100%/100
25% = 25×1% = 100% × 25/100 = 8 × 1/4 = 2
so, on day 2 he walks 8+2 = 10 laps.
on day 3 he walks then 10-1 = 9 laps.
so, now, to calculate the % decrease compared to day 2
100% = 10
1% = 100%/100 = 0.1
how many % is represented by this 1 lap he was walking less ?
1 / 1% = 1 / 0.1 = 10%
so he had a 10% decrease from day 2 to day 3.
Answer:
Step-by-step explanation:
part A:
okay so you saved $300 and choose to spend $50 a week
the 300 is positive and is the y-intercept since thats the amount of money you start with
and the 50 is negative because that is being spent and is the slope
so the equation is:
y = -50x + 300
part B:
the graph will be on the bottom
the (6, 0), aka the x-intercept, shows that in 6 weeks you will be out of money
the (0, 300), aka the y-intercept, shows that in the beginning of summer you have $300
part C:
the y-intercept is 300; it represents the amount of money you have in the beginning of the summer
