Evaluate the expression when x = -2/3 and y= 2/9 x-4y

Mathematics
1 answer:
Ratling [72]3 years ago
6 0

Answer:

-14/9

Step-by-step explanation:

We can plug -2/3 in for x and 2/9 in for y:

-2/3-4(2/9)

-2/3-8/9

We need the fractions to have the same denominator so we can convert -2/3 into -6/9

-6/9-8/9

-14/9

Help please ! Math problem
morpeh [17]

Let's solve your equation step-by-step.

5=(−4)(8)+b

Step 1: Simplify both sides of the equation.

5=(−4)(8)+b

5=−32+b

5=b−32

Step 2: Flip the equation.

b−32=5

Step 3: Add 32 to both sides.

b−32+32=5+32

b=37

A rectangular pool is 6 meters wide and 8 meters long. If you swim diagonally across the pool, how many meters would you be swim
Vitek1552 [10]

If you swim diagonally across the rectangular pool, the distance you swim is 10 meters.

<u>Given the following data:</u>

  • Width of rectangle = 6 meters
  • Length of rectangle = 8 meters

To determine the distance you swim in meters, we would apply Pythagorean's theorem since the width is along the x-axis while the length is along the y-axis.

Note: The diagonal side of the rectangular pool represents the hypotenuse.

Mathematically, Pythagorean's theorem is given by the formula:

Hypotenuse^2 = Opposite^2 + Adjacent^2

Substituting the given parameters into the formula, we have;

Hypotenuse^2 = 6^2 + 8^2\\\\Hypotenuse^2 = 36+64\\\\Hypotenuse^2 = 100\\\\Hypotenuse = \sqrt{100}

Hypotenuse = 10 meters.
