70 POINTS! ∆ABC is reflected across the x-axis, then rotated 90° clockwise about the origin, and finally reflected across the li

madam [21]

Answer:

A'(1, 1); B'(3, 2); C'(1, 2)

Step-by-step explanation:

The original points are A(1,1 ), B(2, 3) and C(2, 1).

Reflecting the triangle across the x-axis will negate every y-coordinate; this maps

(1, 1)→(1, -1); (2, 3)→(2, -3); (2, 1)→(2, -1)

Rotating the figure 90° clockwise about the origin switches the x- and y-coordinates and negates the x-coordinate; this maps

(1, -1)→(-1 -1); (2, -3)→(-3, -2); (2, -1)→(-1, -2)

Reflecting across the line y=x will negate both the x- and y-coordinates; this maps

(-1, -1)→(1, 1); (-3, -2)→(3, 2); (-1, -2)→(1, 2)

An airplane is loaded with cargo and ready to take off. Before it departs, an unknown number of 8 pound boxes, b, will be taken

Monica [59]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Number of 8 pounds before boxes to be removed from cargo = b

Weight in pound of crate to be loaded into cargo = 600 pounds

To achieve a balance , no more Than 400 pounds may be taken off the plane

Hence,

Number of pounds removed must not be more than 400 pounds

(8 pounds * b) ≤ 400

8b ≤ 400

Divide both sides by 8

b ≤ 50

Write an equation for each situation and then solve your equation.

motikmotik

Answer:

Q1. 20x = 200. The value of x is 10

Q2. 7 - 3x = 1. The value of x is 2.

Step-by-step explanation:

In order to find an equation, you have to let the number be any variable, such as m or n or z. So I will let the number be <em>x variable</em>. Then the question says a number is multiplied by 20 is equals to 200 :

Let number = x,

$x \times 20 = 200$

$20x = 200$

$20x \div 20 = 200 \div 20$

$x = 10$

Same for the next question. Given that a number multiplied by 3 :

Let number = x,

$x \times 3 = 3x$

Then subtracted by 7 equals to 1 :

$7 - 3x = 1$

$7 - 3x - 7 = 1 - 7$

$- 3x = - 6$

$- 3x \div - 3 = - 6 \div - 3$

$x = 2$
