Answer 1
Answer:

Answer:

d.$\overline{BC}$

Step-by-step explanation :

We are given that a circle of center O.

We have to find the segment that is secant.

Secant : If a line which intersect the circle at two points.Then the line segment  is called  secant.

a.$\overline{OA}$

It is false because segment OA intersect the circle at one point A only.

b.$\overline{CD}$

It is false because segment CD intersect the circle at point D only.

c.$\overline{BC}$

It is true because it intersect the circle at two points .

d.$\overline{AB}$

It is false because it intersect the circle at one point A only.

Answer:c.$\overline{BC}$

Which ordered pairs in the form (x, y) are solutions to the equation 4x – 5y = 24?

Choose all answers that are correct.

A. (-9,-12)

B. (1,-4)

C. (4,8)

D. (6,0)

Answers

The ordered pairs are  (-9,-12) and (6,0) satisfying the equation 4x – 5y = 24. The correct option is A and D.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given expression is 4x – 5y = 24. We will check the points as:-

4x – 5y = 24

Use:- (-9,-12)

( 4 x -9 ) - ( 5 x 12)  = 24

-36 - 60 = 24

24 = 24

4x – 5y = 24

Use:- (6,0)

( 4 x 6 ) - 0 = 24

24 = 24

Therefore, the ordered pairs are  (-9,-12) and (6,0) satisfying the equation 4x – 5y = 24. The correct option is A and D.
