Let
be the line that passes through both points.
We know that
and
. So:

Solving the system, we get that a= -1 and b = 6.
So the line is equal to
.
Answer:
y=-2
Step-by-step explanation:
you are solving for the variable y
add 3 to the opposite side, so it cancels out
y=-5+3
y=-2
Step-by-step explanation:
it will be x in terms of y or vice versa
Answer:
Growth rate = ln(1.1)/2
Step-by-step explanation:
Given:
P1 = 1.1 P0
Number of year n = 2
Computation:
P1 = P0[eⁿˣ]
x = growth rate
So,
1.1 P0 = P0[eⁿˣ]
1.1 = eⁿˣ
1.1 = e²ˣ
By taking log
Growth rate = ln(1.1)/2
Answer:
Less than 4.70 GB
Step-by-step explanation:
Let x = # of GB that Janelys uses that month. Since Janelys wants to pay less than $70 given that the flat rate for subscribing to that company's data per month is $46.50 and each GB costs $5 to use, the inequality can be written as:
5x + 46.50 < 70
5x < 23.50 Subtract $45.60 from each side.
x < 4.70 GB Divide 5 from each side.
Thus, (if it is whole numbers) Janelys can use 4 GB while staying within her budget or (if decimals are fine) anything less than 4.70 GB. Hope this helped! :D
