Answer:

8 minutes

Step-by-step explanation:

To answer this, set the function y = 9.5x + 62.1 = to 138.1 and solve the resulting equation for x:

9.5x + 62.1 = 138.1

We must isolate x.  Start this process by subtracting 62.1 from both sides of this equation, obtaining:

9.5x = 76

Now divide both sides of this equation by 9.5:

x = 76/9.5 = 8

The water  reaches 138.1 degrees F after 8 minutes.

In a pen with rabbits and chickens someone counted 25 heads and 80 legs a rabbit has four legs and each chicken has 2 legs, how
Komok [63]
I just kind of sat here playing with numbers i dont really know a shortcut but the answer is 10 chickens and 15 rabbits 
10*2= 20 each chicken has two legs so thats 10 heads 20 legs
15*4=60 each rabbit has four legs so thats 15 heads 60 legs
15+10=25 heads
20+60=60 legs

please help me to solve this word problems leading to quadratic equation: A girl is 6 years younger than her brother. the produc
vova2212 [387]

Answer:

Brother is 70.5 and sister is 64.5

Step-by-step explanation:

you will need to set up a simple equation and give out variables.

Girls age = 6-x

Brother's age= x

the you will take those 2 and add them and place them equal to 135:

6-x+x=135

6-2x+6=135+6

The 6 cancels out

2x=141

2x/2=141/2

x=70.5

The brother's age would be 70.5 then and the girl's would be 64.5

The graph of the cube root parent function y =3^sqrt x
umka2103 [35]

Answer:

f(x) =  \sqrt[3]{x + 6} + 1

Step-by-step explanation:

Whenever addition or subtraction occurs within the cube root, it moves horizontally; the opposite is done for the translation, thus if it is addition, which in this case it is, instead of moving the positive direction, the function moves the negative direction.

As opposed to addition or subtraction outside of the cube root, it moves vertically, and in this case, it is translated exactly as stated. Here it states addition, thus the graph moves up in one unit.

The origin of the parent function is at ( 0, 0), in contrast, the origin of the function is at ( -6, 1 )

By using what we know, we can determine that the answer will be f(x) =  \sqrt[3]{x + 6} + 1 since we know that the inside of the cube root should be the opposite of the x value and the outside of the cube root should be the same.
