Mother gives birth to a 8 pound baby. Every 4 months, the baby gains 3 pounds.If x is the age of the baby in months, then y is the weight of the baby in pounds.

Find an equation of a line in the form y = mx + b that describes the baby's weight.

Answers

Answer 1
Answer:

Hello!

The equation, y = mx + b is slope-intercept form. In this equation, m is the slope, and b is the y-intercept.

If the baby was exactly 8 pounds when it was born, then the y-intercept is (0, 8) because at zero months, the baby was eight pounds. To find the rate of change, we can use the the y-intercept (0, 8), and the weight of the baby at four months, which is (4, 8 + 3) → (4, 11).

Since we have two points, we can use the slope formula ((y_(2)-y_(1))/(x_(2)-x_(1))) to find the rate of change.

(8 -11)/(0-4) = (-3)/(-4) = (3)/(4).

The rate of change is 3/4.

Therefore, the equation that describes the baby's weight is y = 3/4x + 8.

A batch of chicken required 3 1/3 cups of flour if a fast food restaurant was making 4 3/7 batches, how much flour would they need ?

Answers

Answer:

14(16)/(21) cups of flour

Step-by-step explanation:

1 batch of chicken required 3 1/3 cups of flour

3(1)/(3) =(3 \cdot 3 + 1)/(3) =(10)/(3)

the fast food restaurant was making 4 3/7 batches.

We need to find how much of flour they need to make 4 3/7 batches

4(3)/(7) =(4 \cdot 7 + 3)/(7) =(31)/(7)

1 batch requires (10)/(3) cups of flour

(31)/(7) batches requires (31)/(7) \cdot (10)/(3)

(310)/(21)=14(16)/(21)
3 1/3 x 4 3/7 

= 10/3 x 31/7 = 310/21 = 14 16/21
