a bean plant grows at a constant rate for a month. after 10 days, the plant is 30 centimeters tall. after 20 days, the plant is
ANTONII [103]

Answer:

(y-30)=2(x-10)

Step-by-step explanation:        

We have been given that a bean plant grows at a constant rate for a month. after 10 days, the plant is 30 centimeters tall. after 20 days, the plant is 50 centimeters tall.

First of all we will find slope of our line using given points.

m=\frac{y_2-y_1}{x_2-x_1}

Upon substituting coordinates of our given points in slope formula we will get,

m=\frac{50-30}{20-10}

m=\frac{20}{10}=2

Therefore, slope of our given line is 2.    

Since the equation of a line in point slope form is (y-y_1)=m(x-x_1).

Upon substituting m=2 and coordinates of one point in above equation we will get,

(y-30)=2(x-10)

Therefore, the equation that models the height of the plant (y) after x days will be (y-30)=2(x-10).

Type the answers in the boxes below.
Vaselesa [24]

Let m and h represent hours Mai spends mowing and hauling, respectively. Then (m+h) will be the number of hours Priya spends babysitting. In order for their earnings to be equal, we must have  

 7m +14h = 8.40(m+h)

 Subtract 7m+8.40h:  5.60h = 1.40m

 Divide by 1.40:  m = 4h

Then the total number of hours worked by either person is

 m + h = (4h) +h = 5h

When only whole numbers of hours are worked, the smallest number of hours that will make earnings equal is 5h, with h=1, or 5 hours. In that time, each will earn 5×$8.40 = $42.

Therefore, each of them must work 5 hours and earn $42 before they go to the movies and Mai will work 4 hours mowing and 1 hour hauling.
