Answer:
$45
Step-by-step explanation:
$7.50 * 4 = $30
$15 + $30 = $45
Hope this helps
A real world example of this equation might look something like this:
John Smith wanted to subscribe to Vague Co. In order to subscribe, there is an initial fee of $60, and an additional fee of $25 for each month that he's subscribed. However, John found another company he wanted to subscribe to, Random Inc., which had an initial fee of $20 and an additional fee of $35 per month. After doing a bit of math, John found that the cost to subscribe to both companies is equal for x months. How many months would it take for the costs of both subscriptions to be equal?
60 + 25x = 35x + 20 Given
60 = 10x + 20 Subtract 25x from both sides
40 = 10x Subtract 20 from both sides
4 = x Divide both sides by 10
It would take 4 months for the costs of a subscription to Vague Co. and Random Inc. to be equal.
We can also think of this problem as f(x) + g(x). Therefore, all we need to do is add the two functions together.
x + 4 + 3x^2 - 8 || Write it out!
3x^2 + x + 4 - 8 || Rearrange in order of decreasing exponents. No need to combine and rearrange all at once!
3x^2 + x - 4 || Combine like terms!
Hope this helps!! :)
Area = length x width and volume = length x width x height soo you would have to multiple 4 and 25 and that’s 100
Answer:
8 ohms
Step-by-step explanation:
given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use either of the given conditions
y = 10 when x = 12 or y = 5 when x = 24, hence
k = 10 × 12 = 120
y = ← equation of variation
when x = 15, then
y = = 8
