B. Rob would like to create a triangle that is

Phantasy [73]

Answer:

$14y + 9$

Step-by-step explanation:

Perimeter of the given triangular above = sum of all its sides.

$= (y + 9) + 2y + (4y - 1) = y + 9 + 2y + 4y -1$

Collect like terms

$= y + 2y + 4y + 9 - 1$

$= 7y + 8$

If Bob creates a new triangle that is 7 less than twice of the perimeter of the triangle above, the expression of the new triangle would be:

$2(7y + 8) - 7$

Simplify

$2*7y + 2*8 - 7$

$14y + 16 - 7$

New perimeter = $14y + 9$

For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.

Trava [24]

11 = 1.375 * 8
22 = 1.375 * 16
33 = 1.375 * 24
Therefore y varies directly with x.
Answer: C ) yes; y = 1.375 x
