r = 1/15
a branliest from the answer will be appreciated
Answer:
<h3>The answer is option D.</h3>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
Slope of the line using points ( 5 , - 1) and
( - 5 , 2) is
m = 2+1/ -5-5 = - 3 / 10
Equation of the line using point ( 5 , - 1) is
y + 1 = -3/10(x - 5)
y = -3/10x + 3/2 - 1
The final answer is
<h3>y = - 3/10x + 1/2</h3>
Hope this helps you.
Answer:
Step-by-step explanation:
Without the variable x, your "f(x) = 3(18)*" is not a function. If you meant
f(x) = 3(18)^x, then the domain is "the set of all real numbers," and the range is (0, infinity).
the initial value is 3: f(0) = 3(18)^0 = 3(1) = 3
740-707.60=32.40
707.60-675.20=32.40
675.20-642.80=32.40
so that means every month you are paying 32.40$ bill. to get how many months you can pay phonebills without depositing any more money devide the 740/32.40=22.83 but you can not pay bill for the 0.83 month so answer will be 22 months
