Suppose that y varies directly with x and y=10 when x=-20. What is y when x =15?
USPshnik [31]

Answer:

15/2

Step-by-step explanation:

You want to first find the connection between the first statement, y=10 and x=20. The connection is that Y is X divided by 2. Then you want to just do the same equation to the y and keep it a fraction. (Hint. a fraction is the same as what you do to divide, its just the equation before you find your answer.) so your answer is 15/2.

Hope its right, and i hope this helped.

What’s the distance between (4,-9) and (5,3)
laila [671]

Answer: Distance = √145

Concept:

Here, we need to know the concept of the distance formula.    

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

<u>Given information</u>

(x₁, y₁) = (4, -9)

(x₂, y₂) = (5, 3)

<u>Given formula</u>

Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

<u>Substitute values into the formula</u>

Distance = \sqrt{(5-4)^2+(3+9)^2}

<u>Simplify values in the parentheses</u>

Distance = \sqrt{(1)^2+(12)^2}

<u>Simplify exponents</u>

Distance = \sqrt{1+144}

<u>Simplify by addition</u>

Distance = \sqrt{145}

Hope this helps!! :)

Add 5/9+7/9 . Simplify the answer and write a mixed number
Step2247 [10]

Hello there!

First you had to solving by the fractions parts.

\frac{5}{9}+\frac{7}{9}=\frac{12}{9}

Then you reducing by the fraction parts of 12/9.

\frac{12}{9}=\frac{4}{3}

And finally, you simplify by the fraction parts of 4/3.

\frac{4}{3}=1 \frac{1}{3}

Solution by Formulas

Applying the fractions formula for addiction.

\frac{(5*9)+(7*9)}{9*9}

\frac{45+63}{81}

=\frac{108}{81}

Simplifying 108/81 and the answer is

=1 \frac{1}{3}

Hope this helps!
