Answer:

So the slope is -5/2.

Step-by-step explanation:

  1. You want to look at the line to find the slope of it.
  2. For slope you want to find rise/run. This is the same as: change in y/change in x. awe have 2 points (the blue dots) to find slope.
  3. With this, let's find the change in y and the change in x.
  • For those 2 dots, the change in y is down 5, which means -5 (if it was up 5 it would be 5)
  • For change in x, it is to the right 2, which means 2 (if it was 2 to the left then it would be -2).
  • Therefore, the slope would be change in y/change in x which is -5/2 (the 3rd option)

Factor by grouping. 9c^3-12c^2+18c-24
xeze [42]

Answer:

9c^3 - 12c^2 - 18c - 24= [3c^2 - 6][3c - 4]

Step-by-step explanation:

Given

9c^3 - 12c^2 - 18c - 24

Required

Factor

Group into 2

[9c^3 - 12c^2] - [18c + 24]

Factorize each group

3c^2[3c - 4] - 6[3c - 4]

Factor out 3c - 4

[3c^2 - 6][3c - 4]

Hence:

9c^3 - 12c^2 - 18c - 24= [3c^2 - 6][3c - 4]

The perimeter of the base of a regular quadrilateral prism is 60 cm, the area of a lateral face is 105 cm2. Find: the volume of
Harman [31]
Since the base is a regular quadrilateral, each of its 4 sides must have length
  s = P/4
  s = (60 cm)/4 = 15 cm

The area of one lateral face is the product of side length and height.
  A = s×h
  105 cm² = (15 cm)×h
Then the height of the prism is
  h = (105 cm²)/(15 cm) = 7 cm

The area of the base is then
  B = s²
  B = (15 cm)² = 225 cm²

The volume of the prism is the product of its base area and height.
  V = Bh
  V = (225 cm²)×(7 cm) = 1575 cm³


The volume is 1575 cm³.

L 5.2.3 Quiz: Two-Variable Systems: Substitution
Misha Larkins [42]

Answer:

We get x=3 and y=21

The ordered pair will be: (3,21)

Step-by-step explanation:

We need to use the substitution method to solve the system of equations.

y = 10x-9\\y = x + 18

For substitution method we substitute the value of x or y from one equation to other.

Let:

y = 10x-9--eq(1)\\y = x + 18--eq(2)

Putting value of y from equation 2 into equation 1

y=10x-9\\Put\:y=x+18\\x+18=10x-9\\x-10x=-9-18\\-9x=-27\\x=\frac{-27}{-9}\\x=3

So, we get value of x=3

Now, for finding value of y, We substitute the value of x

Find value of x from equation 2

y=x+18\\x=y-18

Now, putting value of x in equation 1

y=10x-9\\Put\:x=y-18\\y=10(y-18)-9\\y=10y-180-9\\y-10y=-189\\-9y=-189\\y=\frac{-189}{-9}\\y=21

So, we get value of y=21

So, We get x=3 and y=21

The ordered pair will be: (3,21)
