It would be c because you would subtract 13 on both side and the equation would be x - 13 = 16

How many roots do u thinn
hram777 [196]

Answer:

  • 2 roots
  • 1 root

Step-by-step explanation:

Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).

  y = a(x -h)^2 +k

has leading coefficient "a" and vertex (h, k).

__

<u>f(x) = 1/3(x +5)^2 +7</u>

  vertex: (-5, 7), opens downward

The vertex is above the x-axis, so there are two real roots.

__

<u>f(x) = -5(x -3)^2</u>

  vertex: (3, 0), opens downward

The vertex is on the x-axis, so there is one real root.

What table shows a proportional relationship between x and y?
Aleonysh [2.5K]

Answer:

C

Step-by-step explanation:

A proportional relationship exists where the outputs and inputs have a constant of proportionality. This is a ratio of y/x that is the same between all x and y values in a table.

a. x: 0,1,2 y:2,5,8

2/0 = 0, 5/1 = 5 not proportional

b. x: 0,1,2 y:0,1,4

1/1 = 1, 4/2 = 2 not proportional

c. x: 0,1,2 y:0,3,6

3/1 = 3, 6/2 = 3 YES proportional

d. x 0,1,2 y:2,3,7

2/1 = 2, 3/2 = 1.5 not proportional
