what is the growth factor of y=34×4^x, the initial amount of y=15×3^x and the decay factor of y=17×0.2^x
11Alexandr11 [23.1K]
So the growth factor is the base of the exponential term, so the base of y = 34 * 4^x is 4.
the initial amount is the amount at x = 0
y = 15 * 3^xy = 15 * 3^0y = 15 * 1y = 15 is the initial amount
the decay factor of y=17×0.2^x is same as the growth factor, it is 0.2

Find the value of x.<br> 5x (x+24)
nlexa [21]

Answer:

5x^2+120x

Step-by-step explanation:

5x(x+24)

Step 1: Use distributive property to expand the expression. Multiply 5x separately  with all the terms inside the bracket.

Step 2: 5x(x) = 5x^2

5x(24) = 120x

Answer: 5x^2+120x

Note: If you need to further solve it, you can factor it.

To Factor;

5x^2+120x

Step 1: Factor out the common: 5x

Step 2: 5x times x = x^2

            5x times 24 = 120x

Therefore,

Factored answer: 5x(x+24)

Hope this helps.

Lin's family has completed 90% of a trip. They have traveled 45 miles. How far is the trip?
Lina20 [59]

Answer:

50 miles

Step-by-step explanation:

90% completed (in percentage)

45 mi completed (in miles)

Thus, we can say:

45 is 90% of what number??

This "what number" is the total (what we are trying to find). Now, we let this "what number" part be equal to "x". Also, we know "IS" means "=" and "OF" means "*". Thus we can write:

45 is 90% of what number??

45 = 90% * x

90% converted to decimal is:

90/100 = 0.9

Thus, the equation becomes:

45=0.9x

Solving for x:

45=0.9x\\x=\frac{45}{0.9}\\x=50

The trip is 50 miles

Consider the following expression. +9x+5y+26y Select all of the true statements below
Ugo [173]

Answer:

9x + 31y

Step-by-step explanation:

9x + 31y is the most simplified version of your expression! I believe your question is missing some information but I would love to help in any way I can. Here is how I simplified +9x + 5y + 26y into its simplest form.

Step 1: Add like terms (Add the numbers together with the same terms)

9x + ( 5y + 26y)

Step 2: After adding like terms, you'll be left with 9x + 31y

9x + 31y
