d. (2,2)

please explain how you got your answer.

Answers

Answer 1

Answer:

b

Step-by-step explanation:

[tex]3x - 2y = 12 \\ 2x + 2y = 3 \\ 2y = 3 - 2x \\ 3x - (3 - 2x) = 12 \\ 3x - 3 + 2x = 12 \\ 5x = 15 \\ x = 3 \\ 2y = 3 - 6 = - 3 \\ y = - \frac{3}{2} [/tex]

according to the property √a/√b=√a/b, which choice is equivalent to the quotient below? √72/2​

Answers

6 would be the answer

According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.

What is square root?

The square root of a number is the value of power 1/2 of that number. In other words, it is the number whose product by itself gives the original number.

Given

[tex]\sqrt{\frac{72}{2} }[/tex]

= [tex]\sqrt{36}[/tex]

= 6

According to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex]

[tex]\sqrt{\frac{72}{2} }[/tex] = [tex]\frac{\sqrt{72} }{\sqrt{2} }[/tex]

= [tex]\frac{6\sqrt{2} }{\sqrt{2} }[/tex]

= 6

Thus, according to the property [tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex], [tex]\sqrt{\frac{72}{2} }[/tex] = 6.

Please someone help me quick!!!! It's about Domain and range, Please! Anyone!

Answers

Answer:

Step-by-step explanation:

They already said the domain of f(x) is x≥0.

The smallest value of f(x) is f(0) = 9.

Range of f(x) is y≥9.

The radicand of a square root must be non-negative, so the domain of f⁻¹(x) is x≥9.

The range is y≥0.
