I don't think there is any difference, because 8-15=-7, and 8+(-15)=-7, because if you remove the parentheses, you will also get 8-15.

Please mark brainiest! Will really really appreciate it!

Answer:

$a = 5$

$b = .05$

Step-by-step explanation:

Given

$y = 5\ .05^x$

Required

Determine a and b

An exponential function is represented as:

$y =ab^x$

By comparing: $y =ab^x$ with $y = 5\ .05^x$

$a = 5$

$b = .05$

Natali5045456 [20]

Answer:

Step-by-step explanation:

The speed one (c) is a red herring. Nothing we can see measures her speed.

The only graph that could possibly represent the right answer is D (first graph from the right). It shows that she topped 1/2 way up. It also shows that she took her time about coming down when she was at the top.

The only thing we don't know is A. What's on the vertical axis?

Tammy has scored 82, 78, and 93 on her previous three tests. What score does she need on her next test so that her average (mean

Lyrx [107]

Answer:

She needs a grade of 71 on her next text.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is the sum of all values in the data-set divided by the number of values.

Tammy has scored 82, 78, and 93 on her previous three tests.

Thus, her grades are 82, 78, 93 and x, in which x is her grade in the fourth test.

There are 4 tests.

What score does she need on her next test so that her average (mean) is 81?

We have to find x when the mean is 81. So

$\frac{82 + 78 + 93 + x}{4} = 81$

$253 + x = 324$

$x = 324 - 253$

$x = 71$

She needs a grade of 71 on her next text.
