Answer:
y = 5x + 20
Step-by-step explanation:
Answer:
Y=5x+20
Because 20 is a fee that is in constant value and shouldn't be correlated with the amount of months using the subscription. 5 is the amount charged every month you keep the subscription. Y is outcome of cost, and x is the amount of months.
Answer:
1.4959787 × 10^8
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.
Follow the steps below to see how 149,597,870 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 149,597,870
New Number: 1.49597870
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 1 . 4 9 5 9 7 8 7 0
Decimal Count: 1 2 3 4 5 6 7 8
There are 8 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10^b
a = 1.4959787 (Please notice any zeroes on the end have been removed)
b = 8
Now the whole thing:
1.4959787 x 10^8
Step 4
Check your work:
10^8 = 100,000,000 x 1.4959787 = 149,597,870
Hope this helped.
The subject of this question is Mathematics. The inequality n + 7 ≤ 9 can be solved by subtracting 7 from both sides. The solution is n ≤ 2.
The subject of this question is Mathematics. The question involves solving an inequality involving a number, n, that is added to 7 and is less than or equal to 9. To find the possible values of n, we can subtract 7 from both sides of the inequality:
n + 7 ≤ 9
n ≤ 9 - 7
n ≤ 2
So, the values of n that satisfy the inequality are any number less than or equal to 2.
