Mathematics

6 0

Answer:

Step-by-step explanation:

To see if (2,2) is a solution, substitute them into the inequality and see if it is true.

2 is our x value, and 2 is also our y value

y < 4x – 6

2< 4(2)– 6

2 < 8 – 6

2 < 2

This statement is false. 2 is not less than 2, so (2,2) is not a solution to this equation.

What are the domain and range of the logarithmic function f(x) = log7x? Use the inverse function to justify your answers.

S_A_V [24]

Answer:

Step-by-step explanation:

Since log is defined by all positive real numbers

therefore domain is all positive real number that is ( 0,∞)

Range is given by real numbers

inverse of the given function is (10^x)/7

Whose domain is all real numbers and range is all positive real number

And since we know that domain of function and range of its inverse

& range of a function and domain of its inverse is same

which we are getting in the problem

so answer is justified

Jaclyn estimates that the square root of 50 in the following way: √50 = 2√25 = 2*5 = 10

Harman [31]

Answer:

Jacklyn is wrong because

$\sqrt{50} \ne2 \sqrt{25 }$

Step-by-step explanation:

We have that :Jaclyn estimates that the square root of 50 in the following way:

$\sqrt{50} = 2 \sqrt{25}$

$\sqrt{50} = 2 \times 5$

$\sqrt{50} = 10$

Jacklyn is wrong because she made an error at

$\sqrt{50} = 2 \sqrt{25}$

The correct expression is

$\sqrt{50} = \sqrt{2 \times 25}$

This gives:

$\sqrt{50} = \sqrt{ 25} \times \sqrt{2}$

$\sqrt{50} =5 \sqrt{2}$
