Suzette ran for 1.6 hours and biked for 2.4 hours.

Let x = total hours Suzette ran.

Let y = total hours Suzette biked.

The equation to solve the question will be:

x + y = 4 ...... i

6.5x + 14y = 44.75 ....... ii

From i, y = 4 - x

Put the value of y into equation ii

6.5x + 14y = 44.75

6.5x + 14(4 - x) = 44.75

6.5x + 56 - 14x = 44.75

Collect like terms

6.5x - 14x = 44.75 - 56

-7.5x = -11.25

x = 11.25/7.5

x = 1.6 hours

Since x + y = 4

1.6 + y = 4

y = 4 - 1.6

y = 2.4 hours.

Suzette ran for 1.6 hours and biked for 2.4 hours.

Answer:

Step-by-step explanation:

1. -7 = w + 5

w = -12

(-12 + 5 = -7)

2. -4p + 38 = 10

           -38     -38

-4p = -28

/-4        /-4

p = 7

3. -3 1/2 = -1 1/4b

   /1.25      /1.25

-2 4/5 = -b

2 4/5 = b

or

2.8 = b

What is 3x²+5x+25 when x equals 3
Ksivusya [100]

Answer: 67

Step-by-step explanation:

3x^2 + 5x + 25

x = 3

3(3)^2 + 5(3) + 25

3^2 = 9

3(9) + 5(3) + 25

3 * 9 = 27

27 + 5(3) + 25

5 * 3 = 15

27 + 15 + 25

27 + 15 = 42

42 + 25 = 67

This graph shows transformations between f(x) = 10x and g(x) = a · 10x. Identify the following functions. p(x) = 4 · 10x q(x) =
wel

Anwers:

1. line A

2. line D

3. line B

4. line C

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

Given the original function:

f(x) = 10x

and g(x) = a · 10x is the general from of all transformed functions from the above original function.

  • p(x) = 4 · 10x

The graph of this function is stretched vertically => line A

  • q(x) = –4 · 10x

The graph of this function is stretched vertically and is reflected through the x-asix => line D.

  • r(x) = (1/4) x 10x

The graph of this function is compressed vertically => line B

  • s(x) = (-1/4) x 10x

The graph of this function is compressed vertically and is reflected through the x-asix => line C

Hope it will find you well.
