Instructions?  Pls don't make your helpers guess.

First problem:  f(x) = -(x+4)^2 + 1

a) First, graph g(x) = x^2 (a parabola).  Then reflect your graph in the x-axis, because of the "-" sign.  This will give you the graph of h(x) = -x^2.

b) Now move the entire graph 4 units to the LEFT.  This will give you the graph of j(x) = -(x+4)^2.

c) Now move the entire graph of j(x) UP by one unit.  
This will give you the desired graph, of f(x).

The difference of the square of a number and 36 is equal to 5 times that number. Find the positive solution.
exis [7]

Answer:

x=-4, x=9

Step-by-step explanation:

We write this into words:

difference = subtraction

square = ^2

a number = x

is equal to = =

5 times that number = 5x

x^2-36 = 5x

write in standard form

x^2-5x-36

what adds to -5 and multiplies to -36?

-9 and 4!

(x-9)(x+4)

x-9 = 0

x= 9

x+4 = 0

x=-4

Bob can type 2 letters in 4 hours while bill can do it in six. How many hours will it take them, working together, to type six l
Mnenie [13.5K]

Answer:

7hr 12 min

Step-by-step explanation:

Given that

Bob  can type 2 letters in 4 hours

while on the other hand bill can do it in six hours

We need to find out the no of hours in which they type 6 hours

So,

Bob's rate is

= 2 ÷ 4

= 1 ÷ 2 letter per hour

And,  

Bill's rate is

= 2 ÷ 6

= 1 ÷ 3 letter per hour

Now

Together rate is

= 1 ÷ 2 + 1 ÷ 3 = 5 ÷ 6 letter per hour

We know that

rate × hours = production

Let us assume the hours be x

So,  

(5 ÷ 6)x = 6

x = (6 ÷ 5) × 6

x = 36 ÷ 5

= 7 1 ÷ 5

= 7hr 12 min

Kobotan [32]

Answer:

I’m sorry if I’m wrong

Step-by-step explanation:

A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636

as a fraction it would be 36/99, divide both numbers by 9 to get 4/11

B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666

as a fraction that would be 33/90 , divide both by 3 to get 11/30

C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25
