Students in Ms. Bell’s geometry class created posters of geometric definitions. Which of the following is the most precise definition?


A. Parallel lines are lines that do not intersect.

B. A line segment is part of a line that has an endpoint.

C. Perpendicular lines are lines that intersect at a right angle.

D. An angle is formed by two lines, two segments or two rays in one plane.

Answers

Answer:

C

Step-by-step explanation:

D is missing 2 ideas.

An angle can be formed by a mixture of the types of figures quoted.An angle has common or shared endpoint.

B: to me is unclear. A line does not have an endpoint. A ray does.

A: you need to mention that the lines are coplanar.

I think, brief though it is, C is the most complete and at the same time simplest choice.

Find the sum of the even numbers from 1 to 300
a) 14,280
b) 22,650
c) 16,100
d) 15,460

Answers

Answer:

The answer is 22,650

So, option b for you

Step-by-step explanation:

To find the sum of even numbers from 2 to 300, the formula we use is,

N ( N + 1 )

Where N is given by,

N = [( first number + last number)/2] - 1

So here, N = [ (2 + 300 ) / 2 ] - 1 = 150

And hence Sum = 150 * 151 = 22650

2- 7/8 (48x-8)+4=3(5x-19)

Answers

9514 1404 393

Answer:

infinite solutionsx = -2

Step-by-step explanation:

1. The equation simplifies as follows:

  5(x +2) =10 +5x

  5x +10 = 5x +10 . . . . . eliminate parentheses, write in standard form

  0 = 0 . . . . . . . . . . . . . . subtract 5x+10 from both sides

This is true for all values of x. Any value of x is a solution to this equation. There are an infinite number of solutions.

__

2. 7/8(48x -8) +4 = 3(5x -19) . . . . given

  42x -7 +4 = 15x -57 . . . . . . . . eliminate parentheses

  25x = -50 . . . . . . . . . . . . . add 7-15x to both sides

  x = -2 . . . . . . . . . . . . . . divide by 25

Check

  7/8(48(-2) -8) +4 = 3(5(-2) -19) . . . . substitute for x

  7/8(-96 -8) +4 = 3(-10 -19)

  7/8(-104) +4 = 3(-29)

  -91 +4 = -87 . . . . . . . . . . true

A student says that if 5x2 = 20, then x must be
equal to 2. Do
you agree or disagree with the
student? Justify your answer.

Answers

Answer:

I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:

5(-2)(2) = ?

-10 x 2 = ?

? = -20

-20 ≠ 20

Step-by-step explanation:

Justificaiton:

5(x)(2) = 20

10(x) = 20

10/10(x) = 20/10

x = 2

Second Justification:

5(x)(2) = 20

5/5(x)(2) = 20/5

2x = 4

2x/2 = 4/2

x = 2

Use the graph of f(x) to explain the relationship
between the real zeros of f(x) and its intercept(s).

A. f(x) has one real zero at --2 because the graph of the
function has an intercept at (0.-2).
B. f(x) has two real zeros at -4 and -2 because the
graph of the function has intercepts at (-4,0) and (0,
-2).
C. f(x) has no real zeros because the graph of the
function does not pass through (0,0).
D. f(x) has one real zero at 4 because the graph of the
