5x-4y when x=-2 and y=3

scoray [572]

Answer:

=-22

Step-by-step explanation:

first you fix the x and y into the eqution.

5(-2)-4(3)

Mulitiply and divide (left to right)

5(-2)=-10

mulitply and divide (left to right)

4(3)=12

so the would make the problem look like this

-10-12

add and subtract (left to right)

-10-12=-22

28:42=x:54 what is the value of x.

Arlecino [84]

<h2>Step-by-step explanation:</h2>

We need to think, 28 / 42 = x / 54.

We need to do a proportion for this problem!

First, line up both fractions, then put a equal sign between both fractions.

28 / 42 = x / 54.

We multiply in a diagonal and then we divide by the one without a diagonal.

28 and 54 are a diagonal.

We multiply both numbers!

54 x 28 = 1,512.

Then, we divide by 42.

1,512 / 42 = 36.

Therefore, x = 36.

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!! :)

Please let me know if you have any questions
