A) The equation of the line is: y-1250=35(x-30)

B) The slope is the amount of money earned for one hour of work

Step-by-step explanation:

A)

In order to find the linear function that models the relationship between the number of hours worked and the money earned, we need to find the slope of the function.

Here we have:

Number of hours worked = x = independent variable

Money earned = y = dependent variable

Therefore, the slope can be found as

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

where:

x_1 = 30 h

y_1 = 1250 is the money earned when x = 30 h

x_2 = 55 h

y_2 = 2125 is the money earned when x = 55 h

Substituting,

m=\frac{2125-1250}{55-30}=35

Now we can find the equation of the line using:

y-y_1 = m(x-x_1)

And susbtituting,

y-1250=35(x-30)

B)

In part A, we found that the slope of the line is

m = 35 $/h

The slope of the line represents the rate of increase of the dependent variable (the money) with respect to the rate of increase of the independent variable (the number of hours worked).

In other words, the slope of the line represents the amount of money earned by a worker during one hour of work. So, this means that if the technician works 1 hour, he earns 35$; if he works 2 hours, he earns 70$; and so on.

Deisha can build a fence in 15 hours, and Travis can build a fence in 12 hours. How long will it take them together to build a f
Basile [38]

Answer:

6\frac{2}{3}

Step-by-step explanation:

Deisha's build rate = 1 fence per 15 hours = 1/15 fences per hour

Travis's build rate = 1 fence per 12 hours = 1/12 fences per hour

Working together, their combined rate is 1/15 + 1/12 = 3/20 fences per hour

So it takes them 20/3 = 6 2/3 hours per fence

The height of a triangle is 8 cm more than the base. If the area is 24 cm2, find the height and base of the triangle.
Elden [556K]

Answer:

height = 12 cm

base length = 4 cm

Step-by-step explanation:

area of a triangle

base length × height / 2

x = height

y = base length

x = y + 8

24 = y × (y + 8) / 2

48 = y × (y + 8) = y² + 8y

squared equation

y² + 8y - 48 = 0

solution

y = (-b ± sqrt(b² - 4ac))/(2a)

a = 1

b = 8

c = -48

y = (-8 ± sqrt(64 - 4×-48))/2 = (-8 ± sqrt(64 + 192))/2 =

= (-8 ± sqrt(256))/2 = (-8 ± 16)/2 = -4 ± 8

y1 = -4 + 8 = 4 cm

y2 = -4 - 8 = -12

but a negative base length did not make any sense, so only y = 4 remains.

x = y + 8 = 4 + 8 = 12 cm
