1 answer:
nikdorinn [45]3 years ago

Answer:

4 = a

0 < b <1

Step-by-step explanation:

y = a* b^x

We know that when x=0  y = 4

4 = a * b^0

4 = a * 1

4 = a

That means a = 4

y = 4 * b^x

We also know that it is decreasing which means b must be between 0 and 1

0 < b <1

5(5t + 1) = 25t-7<br> Can someone help me with this solution??
masha68 [24]
Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest

5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false

Answer:

<h2>- 2 {x}^{5}  {y}^{7}</h2>

Last option is correct.

Step-by-step explanation:

- 2 {x}^{3}  {y}^{4}  {x}^{2}  {y}^{3}

Multiply the terms with the same base by adding their exponents

- 2 {x}^{3 + 2}  {y}^{4 + 3}

Add the numbers

- 2 {x}^{5}  {y}^{7}

Hope this helps..

Best regards!
