23. Describe the slopes of perpendicular lines
Answer:
The slopes of two perpendicular lines are negative reciprocals of each other. This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2.
The slopes of perpendicular lines when multiplied together gives the product as -1.
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
Suppose the two perpendicular lines have equations as follows,
y = m₁x + c₁ and y = m₂x + c₂.
Suppose m₁ = tan θ
Then, m₂ = tan (90° + θ)
Apply the trigonometric identity to obtain,
m₂ = tan (90° + θ) = -cot θ
Now, m₁ × m₂ = tan θ × -cot θ = -1
Thus, the products of slopes is -1.
Hence, the product of slopes of two perpendicular lines is -1.

Stacy reasons that since dilations change lengths they also change angles by the same factor. Is she correct? If not, explain why, I will list brainlist if you reply fast
Answer:
Stacy is incorrect. Dilations do not affect the angles of a given figure since dilations create parallel lines and the angles on parallel lines are congruent.

"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question. In this lesson, I'll concentrate on the "plug and chug" aspect of evaluation: plugging in values for variables, and "chugging" my way to the simplified answer.

-7x – 2y = 14
6х + бу = 18
Answer:
es 8 ksnfjskausksufbab 726+47272774
Answer:
(x. y) =(4, 7)
Step-by-step explanation:
-7 x - 2 y = 14
6 x + 6 y = 18
Solve the equation
x = - 2/7 y
6 x + 6 y = 18
Substitute the value of x
6 ( - 2 - 2/7y) + 6 y = 18
Solve the equation
y = 7
Substitute the value of y
x = - 2 - 2/7 x 7
Solve the equation
x = - 4
A possible solution is
(x, y) = (- 4, 7)
Check the solution
- 7 x ( - 4) - 2 x 7 = 14
6 x ( - 4) + 6 x 7 = 18
Simplify
14 = 14
18 = 18
The ordered pair is the solution
(x, y) = ( - 4, 7)
