Answer:

$\frac{25}{16}$

Step-by-step explanation:

$(-\frac{5}{4})^2\\\\ \text {Apply power of a fraction rule: } (\frac{a}{b})^x=\frac{a^x}{b^x}\\\\(-\frac{5}{4})^2 = \frac{-5^2}{4^2}=\frac{25}{16}\\\\\boxed{(-\frac{5}{4})^2=\frac{25}{16}}$

If a line has a slope of 2 and contains the point (-2, 1), what is its equation in

Lapatulllka [165]

Answer:

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = 2 and (a, b ) = (- 2, 1 ) , then

y - 1 = 2(x - (- 2)) , that is

y - 1 = 2(x + 2)

Which of the following best describes an irrational number?

Furkat [3]

Answer:

Option D is correct.

D- A number that cannot be expressed as a fraction, , where p and q are integers

Step-by-step explanation:

Irrational number:

An irrational number can not be expressed as a fraction or ratio of integers, like $\frac{p}{q}$ where p and q are integers

And also it can not be expressed as terminating decimal or repeating decimal

Example of the irrational number is given below.

$\sqrt{8}= 2.82842$

$\pi = 3.14285..$

$\sqrt{3}= 2.82842$

Therefore option D (A number that cannot be expressed as a fraction, , where p and q are integers) is correct .
