Problem 3

Murljashka [212]

Answer:

$-\frac{2}{5}$

Step-by-step explanation:

Given expression:

2x + 5y = -10

The equation of a straight line is;

y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

Now;

let us write the given expression in slope intercept format;

2x + 5y = -10

5y = -2x - 10

y = $-\frac{2x}{5}$ - 2

So, the slope of the line is $-\frac{2}{5}$

The distance from the Earth to Saturn averages 886 million (886,000,000) miles. Write this number in scientific notation.

kiruha [24]

Answer:

8.86 x 10^8

Step-by-step explanation:

Scientific notation means that you represent the standard form of a number like this:

number less than ten x 10 to the ___ power

In standard form, the decimal point is at the end of 886,000,000.

You have to move the decimal point to the left until it creates a number less than 10, but greater than 1:

8.86,000,000

You count how many decimal places you moved it. In this case, it is 8.

So your answer becomes 8.86 x 10^8

Choose all equivalent expression(s).

ElenaW [278]

<u>Given</u>:

The given expression is $a b^{-3 x}$

We need to determine the equivalent expression.

<u>Equivalent expression:</u>

Let us determine the equivalent expression.

The equivalent expression can be determined by simplifying the given expression.

Hence, let us apply the exponent rule to simplify the given expression.

Thus, applying the exponent rule, $a^{-b}=\frac{1}{a^{b}}$ , we get;

$a(\frac{1}{b^{3x}})$

Rewriting the expression, we get;

$a(\frac{1^{3x}}{b^{3x}})$

Simplifying, we get;

$a\left(\frac{1}{b}\right)^{3 x}$

Thus, the equivalent expression is $a\left(\frac{1}{b}\right)^{3 x}$

Hence, Option C is the correct answer.
