Answer:

Yes

Step-by-step explanation:

To make a triangle the 2 smaller sides must join together to become greater than or equal to the biggest side.

8+7=15

Therefore,

side lengths 8, 7, and 15 do create a triangle.

Hope this helps

Answer:

No, this can cannot create a triangle because to create a triangle you need two sides greater than one of the side and since 8+7=15 and 15 cannot be equal to 15 and it had to be more than 15 or so.

Possible ways to create triangle

a+b>c

a+c>b

b+c>a

If the function rule is y equals 3x - 4 what is range when the domain is 7?

nika2105 [10]

Domain is another word for the x value. so, this question just asking us to solve for y when x = 7

first, substitute in x

y = 3(7) -4

and then solve for y

y = 21 - 4
y = 17

so, the range is 17 when the domain is 7
