Which set of three numbers could be better he side lengths of a triangle

The sides of a real triangle satisfy the <em>triangle inequality</em>, which just says any two sides add up to more than the third.  It's strictly more; if two sides add up to exactly the third that's called a <em>degenerate triangle</em>.  It's not a real triangle because the vertices are three collinear points.

The triangle equality fails when the sum of the two smallest sides fails to exceed the the largest side.

A.  4+6=10, degenerate triangle, not a real triangle

B.  4+7>7, isosceles triangles are real, SELECT

C. 4+3<10, not a real triangle

D. 4+7=11, degenerate triangle again

What’s the axis of symmetry?
Sloan [31]

Answer:

x = -1

Step-by-step explanation:

With the axis of symmetry, think of it as where you would slice this line in half, and both sides would look identical to each other. Since this is a quadratic function, this would be at where the vertex is.

The vertex is the part of the line where it "turns" around and starts going the other way. So vertex of this line is at (-1, 3).

Therefore, the axis of symmetry is at x = -1. This is since the function is pointing either up/down, and any value that is x = _ is a vertical line.

Suri's age is 4 less than 3 times her cousin's age. Suri is 17 years old. Which method can be used to find c, her cousin's age?
Mila [183]

Answer:

7 years

Step-by-step explanation:

Suri's age=17 years

Her cousin's age =c

Suri's age is 4 less than 3 times her cousin's age

4 less than 3 times her cousin's age means subtract 4 from 3 times her cousin's age

17=3c - 4

Find c which is her cousin's age

Add 4 to both sides

17+4=3c - 4 + 4

17+4=3c

21=3c

Divide both sides by 3

21/3=3c/3

7=c

Therefore,

C= 7

Her cousin's age = 7 years
