Which set of ordered pairs is not a function?

2 answers:

6 0

The answer is the third one because you can't have several ordered pairs that have the same y. I hope this was what you were looking for! Hoped this helped you!

Rewrite the following expression.

faust18 [17]

We have been given the expression

$x^{\frac{9}{7}}$

We have the exponent rule

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

Using this rule, we have

$x^{\frac{9}{7}}= x^{9^{(\frac{1}{7})}}$

Now, using the fact that $x^{\frac{1}{n}}=\sqrt[n]{x}$ , we get

$x^{\frac{9}{7}}= \sqrt[7]{x^9}\\
\\
x^{\frac{9}{7}}=\sqrt[7]{x^7\times x^2}\\
\\
x^{\frac{9}{7}}=x\sqrt[7]{x^2}$

D is the correct option.

Create a linear function that has a rate of change of -4 and a solution at (-5,2)

san4es73 [151]

You would use the point-slope equation of y-y₁=mx(x-x₁)

So the rate of change is the slope and equals m, so m=-4

and has a solution at (-5,2) which would be the (x₁, y₁) and then it is just plugging in the numbers

y - (2) = (-4)(x - (-5))

y - 2 = -4 (x+5)

y - 2 = -4x - 20

y = -4x - 18

The sum of three numbers is 855. One of the numbers, x, is 50% more than the sum of the other two numbers. What is the value of

Snowcat [4.5K]

Answer:

The value of x = 513

Step-by-step explanation:

Let x, y, and z be the three numbers

Given

$x+y+z=855$

Assuming x be the number which is 50% more than the sum of the other two numbers.

i.e.

(150)% of (y+z) = 1.5(y+z)

y + z = x/1.5

As we know that

$x + y + z = 855$

substituting y + z = x / 1.5 in the equation

$x+\frac{x}{1.5}=855$

Multiply both sides by 1.5

$x\cdot \:1.5+\frac{x}{1.5}\cdot \:1.5=855\cdot \:1.5$

$1.5x+x=1282.5$

$2.5x=1282.5$

Divide both sides by 2.5

$\frac{2.5x}{2.5}=\frac{1282.5}{2.5}$

$x = 513$

Therefore, the value of x = 513
