What is the slope of the line that passes through the points (-10, -8)(−10,−8) and (-8, -16) ?(−8,−16)? Write your answer in sim

photoshop1234 [79]

The slope of the line that passes through points ( -10, -8 ) and ( -8, -16 ) is -4.

Explanation:

Points given = ( -10, -8) and ( -8, -16)

Slope = ?

( -10, -8 ) : x1 = -10 and y1 = -8

( -8, -16 ) : x2 = -8 and y2 = -16

We know,

slope = y2 - y1 / x2 - x1

Slope = -16 - ( -8) / -8 - (-10)

slope = -16 + 8 / -8 + 10

slope = -8 / 2

slope = -4

Therefore, slope of the line that passes through points ( -10, -8 ) and ( -8, -16 ) is -4.

The angles of a triangle add up to 180 degrees. The second angle is 30 degrees larger than the smallest angle. The third angle i

Rudik [331]

Answer:

Step-by-step explanation:

first angle = x

second angle = x+30

third angle = 4x

x + (x+30) + 4x = 180

6x + 30 = 180

6x = 180 - 30

6x = 150

x = 150:6

x = 50

One integer is 3 more than 5 times another. The product is 54, what are the two integers?

densk [106]

Answer:

The two integers are 18 and 3.

Step-by-step explanation:

Consider the provided information.

It is given that One integer is 3 more than 5 times another.

Let us consider the integer is x.

Then 3 more than 5 times of x is:

$3+5x$

The product of the provided two numbers is 54. i.e.

$x(3+5x)=54$

$3x+5x^2=54$

$5x^2+3x-54=0$

Use the formula of the quadratic equation:

For the equation $ax^2+bx+c=0$ the solutions are:

$x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

By comparing the obtained equation with the above equation, it can be concluded that a = 5, b = 3 and c = -54. Substitute the these values in the above formula.

$x_{1,\:2}=\frac{-3\pm \sqrt{3^2-4\cdot \:5\left(-54\right)}}{2\cdot \:5}$
