For this case we have that the slope of a line is given by:

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

We have the following points:

(x1, y1) = (- 2,19)\\(x2, y2) = (5, -9)

Substituting:

m = \frac {-9-19} {5 - (- 2)}\\m = \frac {-28} {5 + 2}\\m = \frac {-28} {7}\\m = -4

Thus, the slope-intercept form equation is given by:

y = -4x + b

We substitute any of the points to find the cut point with the y axis.

-9 = -4 (5) + b\\-9 = -20 + b\\b = -9 + 20\\b = 11

So, we have:

y = -4x + 11

What is the sum of the measures of the interior angles formed by the boundary of this team pennant?
Debora [2.8K]
I think the correct answer from the choices listed above is option C. The <span>sum of the measures of the interior angles formed by the boundary of this team pennant should be 180 degrees since all triangles has a sum of interior angles which is 180 degrees. Hope this answers the question.</span>

What is the solution of quadratic system of equations ?
kobusy [5.1K]

Answer:

(- 1, 1) and (- 5, - 35)

Step-by-step explanation:

since both equations express y in terms of x, equate the right sides

x² + 15x + 15 = - x² + 3x + 5 ( subtract - x² + 3x + 5 from both sides )

2x² + 12x + 10 = 0  ( divide all terms by 2 )

x² + 6x + 5 = 0 ← in standard form

(x + 1)(x + 5) = 0 ← in factored form

equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 5 = 0 ⇒ x = - 5

substitute these values into either of the 2 equations and solve for y

x = - 1 : y = (- 1)² + 15(- 1) + 15 = 1 - 15 + 15 = 1 ⇒ (- 1, 1 )

x = - 5 : y = (- 5)² + 15(- 5) + 15 = 25 - 75 + 15 = - 35 ⇒ (- 5, - 35 )

None of the given options

. Gold has a density of 19.32 g/cm3. If a square pyramid has a base edge length of 5 cm, height of 6 cm, and a mass of 942 g, is
trapecia [35]

Answer:

The answer to your question is: It is not made of gold.

Step-by-step explanation:

Data

density = 19.32 g/cm³

side = 5 cm

height = 6 cm

mass = 942 g

Formula

                          V = \frac{1}{3} L^{2}  h

L² = 5 x 5 = 25 cm²

                          V = \frac{1}{3} 25 x 6

                          V = 50 cm³

density = 942 g / 50 cm³

            = 18.84 g/cm³  

It is not made of gold because the density calculated is lower than the density reported in books.
