One could analyze the ideas expressed in papers and lectures of experts. Since these people are well educated and creditable, their ideas should be taken seriously. In this case, the author argues that people should pay for the things that they own. By finding a credible expert that shares the same opinion, the idea can be verified.

The length of a rectangle is 4x + 5 and the width is 8x - 4. what is the perimtleter?

Luda [366]

Hi there!

Since the formula for finding the perimeter of a rectangle is length×2 + width × 2, we can follow this rule.

2 (4x + 5) + 2 (8x - 4)
= 8x + 10 + 16x - 8
= 24x + 2

So, the perimeter is 24x + 2.

Hope this helps!

Triangle △ABC is reflected across line n to create △ A'B'C', What is the measure of ∠C?

Ilya [14]

The measure of ∠C is 54°.

<h3>To solve the problem :</h3>

let us assume that line n is a mirror.

∴ ∠A = ∠A' = 59°

∠B = ∠B' = 67°

∠C = ∠C'

According to property of triangles :

Sum of all angles of a triangle is 180°.

∴ A + B + C = 180°

59 + 67 + C = 180

C = $180 - (59 +67)$

C = 54°

<h3>∴ The measure of ∠C is 54°.</h3>

A) What is the equation of the line that passes through the given pair points in slope-intercept form?

lesya [120]

A)

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (2, 5.1) and (-1, -0.5). Substitute:

$m=\dfrac{-0.5-5.1}{-1-2}=\dfrac{-5.6}{-3}=\dfrac{5.6}{3}=\dfrac{56}{30}=\dfrac{28}{15}$

Therefore we have:

$y=\dfrac{28}{15}x+b$

Put the coordinates of the point (-1, -0.5) ot the equation:

$-0.5=\dfrac{28}{15}(-1)+b$

$-0.5=-\dfrac{28}{15}+b$ <em>multiply both sides by 2</em>

$-1=-\dfrac{56}{15}+2b$ <em>add $\dfrac{56}{15}$ to both sides</em>

$\dfrac{41}{15}=2b$ <em>divide both sides by 2</em>

$b=\dfrac{41}{30}$

Answer: $\boxed{y=\dfrac{28}{15}x+\dfrac{41}{30}}$

-------------------------------------------------------------------------

B)

We have the points (-2, 3) and (3, -4).

Calculate the slope:

$m=\dfrac{-4-3}{3-(-2)}=\dfrac{-7}{5}=-\dfrac{7}{5}$

Therefore we have:

$y=-\dfrac{7}{5}x+b$

Put the coordinates of the point (-2, 3) to the equation of a line:

$3=-\dfrac{7}{5}(-2)+b$

$\dfrac{15}{5}=\dfrac{14}{5}+b$ <em>subtract $\dfrac{14}{5}$ from both sides</em>

$\dfrac{1}{5}=b\to b=\dfrac{1}{5}$

Answer: $\boxed{y=-\dfrac{7}{5}x+\dfrac{1}{5}}$

The image of the point (-3, 8) under a translation is (1, 10). Find the coordinates of

Dafna11 [192]

Answer:

(9, - 2 )

Step-by-step explanation:

Given (- 3, 8 ) → (1, 10 )

That is the x- coordinate of the image is 4 more than the original.

The y- coordinate of the image is 2 more than the original, so

Translation rule is (x, y ) → (x + 4, y + 2 ), thus

(5, - 4 ) → (5 + 4, - 4 + 2 ) → (9, - 2 )
