What is the perimeter of ABC with vertices A (-2,9) , B (7,-3) , C (-2,-3) in the coordinate plane?

docker41 [41]

9514 1404 393

Answer:

D. 36 units

Step-by-step explanation:

Using the distance formula, we find the length of AB to be ...

d = √((x2 -x1)² +(y2 -y1)²)

d = √((7-(-2))² +(-3-9)²) = √(81 +144) = √225 = 15

The line BC is horizontal, so its length is the difference of the x-coordinates:

BC = 7 -(-2) = 9

The line AC is vertical, so its length is the difference of the y-coordinates:

AC = 9 -(-3) = 12

The sum of the lengths of the sides of the triangle is ...

P = 15 + 9 + 12 = 36

The perimeter is 36 units.

State all integer values of x in the interval (2,8) that satisfy the following inequality:

lidiya [134]

Answer:

3,4,5,6 and 7

Step-by-step explanation:

Given

$5x + 4 \ge 19$

Required

State the values of x within 2 and 8

$5x + 4 \ge 19$

Collect Like Terms

$5x \ge 19 - 4$

$5x \ge 15$

Divide both sides by 5

$\frac{5x}{5} \ge \frac{15}{5}$

$x \ge 3$

(2,8) is an open interval which means that 2 and 8 are not inclusive of the values of x.

So:

The values of $x \ge 3$ are: 3,4,5,6 and 7
