<span>For three numbers to represent lengths of the sides of a triangle, the sum of each pair must be greater than the remaining side.

A)
3 + 4 = 7
3 + 5 = 8
5 + 4 = 9

B)
2 + 5 = 7
2 + 8 = 10
5 + 8 = 13

C)
2 + 12 = 14
2 + 15 = 17
15 + 12 = 27

D)
3 + 3 = 6
3 + 7 = 10
3 + 7 = 10

In all these, only A have the sum of the numbers greater than the numbers itself. So the answer is A.

Find the slope intercept equation of the line<br><br> PLEASE HELP ME!!!!!

Alexxx [7]

Answer:

y = -x + 6

Step-by-step explanation:

<u>Slope-intercept form:</u>

y = mx + b, where m is slope and b is y-intercept

We see on the graph y-intercept is b = 6, point (0.6)

To find the slope we need a second point, choosing point (5, 1)

<u>Using slope formula:</u>

m = (1- 6)/(5 - 0) = -5/5 = -1

<u>So the line is:</u>

y = -x + 6

Create a number pattern that follows the rule

vazorg [7]

Answer:

The pattern form is 8,15,34,71 which follows the rule $x^3+7$

Step-by-step explanation:

Given : Rule $x^3+7$

To find : Create a number pattern that follows the rule. Use at least three terms in the pattern ?

Solution :

Rule $x^3+7$

Put n=1,

$x^3+7=(1)^3+7$

$x^3+7=1+7=8$

Put n=2,

$x^3+7=(2)^3+7$

$x^3+7=8+7=15$

Put n=3,

$x^3+7=(3)^3+7$

$x^3+7=27+7=34$

Put n=4,

$x^3+7=(4)^3+7$

$x^3+7=64+7=71$

The pattern form is 8,15,34,71 which follows the rule $x^3+7$
