Hi Jasmine

x²/y + x²/z
if x = 10, y=-5 , z = -2
Evaluate x, y,z
10^2/-5 + 10^2/-2
10²/-5 + 10²/-2
- 70

I hope that's help !

Answer:

The answer is -70.

Step-by-step explanation:

In order to determine the answer, we have to know about "replacing variables". In any expression which contains variables, we can replace them by values to get different results.

So, in this case, we have the variables "x", "y" and "z", and also we have the values to replace every variable.

Replacing those values:

$\frac{x^2}{y}+\frac{x^2}{z}\\ \\x=10\\y=-5\\z=-2\\\\\frac{(10)^2}{(-5)}+\frac{(10)^2}{(-2)}\\ \frac{100}{(-5)}+\frac{100}{(-2)}\\ -20-50\\-70$

Finally, the value of the expression is -70.

A student council sells 44 bouquets for $176. Which equation represents the

vesna_86 [32]

Answer:

$y = 4x$

Step-by-step explanation:

Given

$x = 44$

$y = 176$

Required

Determine the relationship between x and y

First, we calculate the unit rate, using:

$y = kx$

Where k is the unit rate.

Substitute 176 for y and 44 for y

$176 = k * 44$

Divide both sides by 44

$\frac{176}{44} = \frac{44*k}{44}$

$\frac{176}{44} = k$

$4 = k$

$k = 4$

Substitute 4 for k in $y = kx$

$y = 4x$

Hence, the relationship between x and y is: $y = 4x$

Ivahew [28]

Answer:

The answer is D

Step-by-step explanation:

You can find it by expanding the equation in the form of y = mx + b :

y - 4 = 3(x + 1)

y - 4 = 3x + 3

y = 3x + 3 + 4

y = 3x + 7

Then, looking at the equation "b" is a y-intercept. The line that touch/passes through y-axis is called y-intercept. From the equation, we know that 7 is the y-intercept.

By looking at the diagram, only Graph D is suitable for this equation because the line has touches 7 at y-axis.

Are 22 42 60 a right triangle or not?

Lelechka [254]

Answer:First things first, let's explain what a right triangle is. The definition is very simple and might even seem obvious for those who already know it: a right-angled triangle is a triangle where one and only one of the angles is exactly 90°. The other two angles will clearly be smaller than the right angle because the sum of all angles in a triangle is always 180°.

In a right angled triangle the sides are defined in a special way. The side opposing the right angle is always the biggest in the triangle and receives the name of "hypotenuse". The other two sides are called catheti. The relationship between the hypotenuse and each of the cathetus is a very simple one, as we will see when we will talk about Pythagoras' theorem.

Hypotenuse calculator

If all you want to calculate is the hypotenuse of a right triangle, this page and its right triangle calculator will work just fine. However, we would also recommend to use the specific tool we have developed at Omni Calculators: the hypotenuse calculator. The hypotenuse is opposite the right angle and can be solved by using the Pythagorean theorem. In a right triangle with cathetus a and b and with hypotenuse c, Pythagoras' theorem states that: a² + b² = c².

To solve for c, take the square root of both sides to get c = √(b²+a²). This extension of the Pythagorean theorem can be considered as a "hypotenuse formula". A Pythagorean theorem calculator is also an excellent tool for calculating the hypotenuse.

Let's now solve a practical example of what it would take to calculate the hypotenuse of a right triangle without using any calculators available at Omni:

Obtain the values of a and b,

Square a and b,

Sum up both values: a² + b²,

Take the square root of the result,

The square root will yield a positive and negative result. Since we are dealing with length, disregard the negative result,

The resulting value is the value of the hypotenuse c.

Now let's see what the process would be using one of Omni's calculator, for example, the right triangle calculator on this web page:

Insert the value of a and b into the calculator

Obtain the value of c immediately

As a bonus, you will get the value of the area for such a triangle.
