Which function has a domain of x 25 and a range of y s3?

Mathematics

lions [1.4K]3 years ago
3 0

Answer:

Step-by-step explanation:

The function  has a domain x ≥ 5.

This is because the function remains real for (x - 5) ≥ 0 as negative within the square root is imaginary.

Hence, (x - 5) ≥ 0

⇒ x ≥ 5

Now, for all x values that are greater than equal to 5 the value of  will be negative.

So,  

⇒  

⇒ y ≤ 3

Therefore, the range of the function is y ≤ 3. (Answer)

Answer:

a:b = -17:1

Step-by-step explanation:

Given

\frac{a-3b}{a+2b} = \frac{4}{3}

Required

Find a:b

\frac{a-3b}{a+2b} = \frac{4}{3}

Cross Multiply

3(a-3b) = 4(a+2b)

Open brackets

3a - 9b = 4a + 8b

Collect Like Terms

3a - 4a = 8b+9b

-a = 17b

Divide through by -b

\frac{-a}{-b} = \frac{17b}{-b}

\frac{a}{b} = \frac{17}{-1}

\frac{a}{b} = \frac{-17}{1}

Represent as a ratio

a:b = -17:1

x = 9

Step-by-step explanation:

Each angle equals 60 since it is an equilateral triangle

7x-3 = 60

add 3

7x = 63

divide by seven on both sides

x = 9

I hope this helps!!
