-(x+2) = (-x-2)

3(7x-8) = 21x-24

7(x+3)-5x = 2x+21

These are the equations simplified
Hope this helped :)

In 1986, the Chicago Bears beat the New England Patriots by 36 points in the Super Bowl. If a total of

bulgar [2K]

First subtract the difference of the points from total points:

56-36 = 20

Now divide 20 points by 2 teams:

20/2 = 10

Now add 36 to 10: 36 + 10 = 46

The final score was 46 to 10

Chicago got 46 points New England got 10 points.

Step-by-step explanation:

Alternate exterior angles are two angles that are congruent to each other:

1. Set the two angles equal to each other: 7x-4 = 6x+5

2. Combine like terms and solve for x: x = 9

Determine whether the ordered pair (1, 1) is a solution of the inequality. y ≤ -3x+1

solong [7]

Answer: $\textsf{(1, 1) is NOT a solution of the inequality}$

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

Given: $y \le-3x + 1$

Find: $\textsf{Determine if (1, 1) is a solution of the inequality}$

Solution: In order to determine if (1, 1) is a solution we need to plug in 1 for the x values and 1 for the y values and see if the equation evaluated to true.

Plug in the values

$y \le-3x + 1$

$1 \le-3(1) + 1$

Simplify

$1 \le-3 + 1$

$1 \le-2$

As we can see the expression states that 1 is less than or equal to -2 which is false therefore (1, 1) is NOT a solution of the inequality.
