Fin k if y =kx2, and y=25 when x =5​

Mathematics
1 answer:
slavikrds [6]3 years ago
6 0

Answer:

k = 1

Step-by-step explanation:

Given

y = kx^2

Required

Find k, when: y=25;x=5

We have:

y = kx^2

Substitute 25 for y and 5 for x

25 = k * 5^2

25 = k * 25

Divide both sides by 25

\frac{25}{25} = \frac{k * 25}{25}

\frac{25}{25} = k

1 = k

k = 1

<em>Hence; the value of k is 1</em>

granola bite contains 27 calories. Most of the calories come from grams of carbohydrates. The rest come from other ingredients.
azamat

Answer:

5 1/2

Step-by-step explanation:

The calories contained are from grams of carbohydrates and other ingredients

One gram of carbohydrate contains 4 calories

The equation 4c + 5 = 27 represents the relationship between these quantities.

1. 5 from the equation represent calories from other ingredients

2. Neither 8 nor 3 is the solution to the equation

4c + 5 = 27

When 8 is the solution

4(8)+5=27

32+5=27

37=27

When 3 is the solution

4(3)+5=27

12+5=27

17=27

Neither 8 nor 3 is the solution to the equation because 8 gives a higher calories in the granola bite and 3 gives a lower calories in the granola bite.

3. Solution to the equation

4c + 5 = 27

4c= 27-5

4c = 22

Divide both sides by 4

c=22/4

=5 2/4

=5 1/2

The solution to the equation is 5 1/2
