Brooke found the equation of the line passing through the points (–7, 25) and (–4, 13) in slope-intercept form as follows.
Arturiano [62]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

m = \frac {y2-y1} {x2-x1}

We have the following points:

(x1, y1): (- 7,25)\\(x2, y2): (- 4,13)

Substituting the values:m = \frac {13-25} {- 4 - (- 7)} = \frac {-12} {- 4 + 7} = \frac {-12} {3} = - 4

Thus, the line is of the form:

y = -4x + b

We substitute one of the points and find "b":

13 = -4 (-4) + b\\13 = 16 + b\\b = 13-16 = -3

Finally we have to:

y = -4x-3

Answer:

The equation es y = -4x-3

Determine the shaded areas part 2​
shutvik [7]

9514 1404 393

Answer:

  (a) cannot be determined

  (b) 44 cm^2

  (c) 87 m^2

  (d) 180 m^2

  (e) 132 m^2

Step-by-step explanation:

(a) missing a horizontal dimension

__

(b) The difference between the bounding rectangle and the lower-left cutout is ...

  (8 cm)(7 cm) -(3 cm)(4 cm) = (56 -12) cm^2 = 44 cm^2

__

(c) The difference between the bounding rectangle and the center cutout is ...

  (13 m)(7 m) -(4 m)(1 m) = (91 -4) m^2 = 87 m^2

__

(d) The difference between the bounding rectangle and the two cutouts is ...

  (20 m)(25 m) -(16 m)(20 m) = (20 m)(25 -16) m = (20 m)(9 m) = 180 m^2

__

(e) The difference between the bounding rectangle and the two cutouts is ...

  (14 m)(12 m) -(12 m)(3 m) = (12 m)(14 -3) m = (12 m)(11 m) = 132 m^2

Stacy placed an order for 4 2/5 sacks of brown lentils and 1 sack of green lentils. How much more brown lentils did Stacy order?
OlgaM077 [116]

Stacy ordered 3\frac{2}{5} more sacks of brown lentils.

Step-by-step explanation:

Given,

Sack of brown lentils ordered = 4\frac{2}{5}=\frac{22}{5}

Sack of green lentils ordered = 1

Difference = Sacks of brown lentils - Sacks of green lentils

Difference = \frac{22}{5}-1

Difference = \frac{22-5}{5}

Difference = \frac{17}{5} = 3\frac{2}{5}

Stacy ordered 3\frac{2}{5} more sacks of brown lentils.
