Answer:

  (a) isosceles

  (b), (c) scalene

Step-by-step explanation:

The lengths of the sides can be found from the distance formula:

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.

We find triangle (a) has two sides the same length, so it is isosceles.

The other two triangles have three different side lengths, so they are scalene.

It is impossible to specify an equilateral triangle using rational coordinates.

Answer:

x ≥ 1

Step-by-step explanation:

3 + 4x ≥ 7

3 - 3 + 4x ≥ 7 - 3

4x ≥ 4

4x / 4 ≥ 4 / 4

x ≥ 1

Answer:

Step-by-step explanation:

(x^2+8x+8)+(-10x^2+5x) = (x^2-10x^2) + (8x+5x) + 8

= -x^2 +13x + 8

Answer:

-9x^+13x+8

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

Let the numbers be 2x,5x and 7x respectively.

2x+5x+7x=28

14x=28

x=28/14=2

Therefore the numbers are 2(2)=4,5(2)=10 and 7(2)=14

The smallest number is 4

Answer:

Y=2x-3/4

Step-by-step explanation:

1) put all the information you have in Y=mx+b form

2) y=2x-3/4

2 is the slope and -3/4 is the y intercept

Answer:

y= 11+x

Step-by-step explanation:

Given data

Larry earned $11 walking his neighbors' dogs on Saturday

Also, he earned some extra amount say x dollars on Sundays

let the total earnings be y

Therefore the total earnings can be expressed as

y= 11+x

Answer:

With a z score of 1.75, mean of 28 and standard deviation of 8

1.75=(Xi-28)/8

14=(Xi-28)

42 = Xi

Step-by-step explanation:

Answer:

AROC =6

Step-by-step explanation:

Let f(x)=6x-9

When x=2

f(2) =6(2)-9 = 3

When x=0

f(0)=6(0)-9 =-9

So, average rate of change AROC=[tex]\frac{3-(-9)}{2-0} =\frac{12}{2}[/tex] =6

So, AROC=6

You don't need to, I'm just glad I could help. ^^

Answer:

30°

Step-by-step explanation:

The circumscribed angle is half the difference of the intercepted arcs

arc ELD = 360° - 150° = 210° , then

angle = [tex]\frac{1}{2}[/tex] (210 - 150)° = 0.5 × 60° = 30°

Answer:

30

Complete question :

From the set {24, 36, 72}, use substitution to determine which value of x makes the inequality true.

x ÷ 12 < 3

Answer:

24

Step-by-step explanation:

Given the inequality : x ÷ 12 < 3

Substitute the values in the set for X and test the inequality expression if it hoods true for each of the substituted value.

x = 24

24 ÷ 12 < 3

2 < 3 (true)

x = 36

36 ÷ 12 < 3

3 < 3 (false)

x = 72

72 ÷ 12 < 3

6 < 3 (false)

Answer:

8n - 15

Step-by-step explanation:

for finding the nth term we need to figure out the difference between the numbers:

3,11,19 = difference of 8

multiples of 8:

8,16,24,32,40...

the nth term would be 8n - 5 because in order to get to 3 from 8, we minus 5

Answer:

ok I will help you because I am a nice person:)

Answer:

Step-by-step explanation:

an = 3 + (n-1)11

an = 3 + 11n - 11

an = -8 + 11n OR 11n - 8

Answer:

15 dogs

Step-by-step explanation:

dogs : cats : rabbits

5 : 2 : 1

? : ? : 3

1 rabbit = 2 cats

2 cats = 5 dogs
