Answer:

Question 9: 35    Question 10: 10

Step-by-step explanation:

Use BEDMAS (Brackets Exponents Division Multiplication Addition Subtraction).

Question 9:

Start with the brackets.

10 x 4 - (7 - 2)

= 10 x 4 - (5)

Then, multiply 10 and 4.

= 40 - 5

Solve the subtraction.

= 35

Question 10:

Start with the brackets.

1 - (2 - 3) + 8

= 1 - (-1) + 8

= 1 - - 1 + 8

(Two negatives = a positive)

= 1 + 1 + 8

Add the numbers.

= 10

The endpoints of a side of rectangle ABCD in the coordinate plane are at A(3, 5) and B(5, 1). Find the equation of the line that
andreyandreev [35.5K]

Answer:

2x + y = 16

Step-by-step explanation:

In rectangle side AB and side CD are parallel, so the slope of both the lines will be same it means that they are parallel to each other.

slope of line AB:

\textrm{m}=\frac{\textrm{y}_{A}-\textrm{y}_{B}}{\textrm{x}_{A}-\textrm{x}_{B}}\\\textrm{m}=\frac{5-1}{3-5}=\frac{4}{-2}=-2\\\therefore \textrm{m}=-2

slope of line CD = slope of line AB = -2

∴ equation of line CD:

\textrm{y}-\textrm{y}_{C}=\textrm{m}(\textrm{x}-\textrm{x}_{C})\\ \textrm{y}-2=-2(\textrm{x}-7)\\2\textrm{x}+\textrm{y}=16
