The graph of the parent function X^2 is a parabola, keeping this in mind you know that the graph will have two rays coming from the vertex, 

I find it useful to plot points for these problems, but if you have a TI calc then it'll be easier to see the graph right away. 

Answer: 2

Find three consecutive even integers such that six times the sum of the first and the third is twenty - four greater than eleven
dedylja [7]

Answer:

1st = 22

2nd = 24

3rd = 26

Step-by-step explanation:

1st = x

2nd = x +2

3rd = x + 4

6(x + x + 4) = 24 + 11(x + 2)

6(2x + 4) = 24 + 11x + 22

12x + 24 = 46 + 11x

x + 24 = 46

x = 22

x + 2 = 24

x + 4 = 26

write the equation in point slope form of the line that is perpendicular to 3x-2y=-8 going through the point (-6,5
tatiyna

Answer:

y-5 = -2/3 (x+6)

Step-by-step explanation:

-2y = -3x -8

2y = 3x + 8

2/2 y = 3/2 x + 8/2

y = 3/2 x + 4


slope of a perpendicular line

- 2/3


y-5= -2/3(x-(-6)

y-5 = -2/3 (x+6)

Assume a class has 17 members.
Helga [31]
A) 4080
B) 6188

A is a permutation, since order would matter:
P(17, 3)=\frac{17!}{(17-3)!}=\frac{17!}{14!}=4080

B is a combination, since order does not matter:
_{17}C_5=\frac{17!}{5!12!}=6188
