The to bottom numbers will be the same because it's an isosceles triangle 55+55=110 angles in a triangle add up to 180 so 180 - 110 = 70

A line passes through the two points (-4,6) and (2,-5). Calculate the following parts:

Viktor [21]

A line passes through the two points (-4,6) and (2,-5). 11x +6y - 80 = 0 is the given line equation.

<h3>What is the slope of a line which passes through points ( p,q) and (x,y)?</h3>

Its slope would be:

$m = \dfrac{y-q}{x-p}$

The slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

The slope m of the line is given as

$m = \dfrac{y-q}{x-p}\\\\ m = \dfrac{-5-6}{2+4}\\\\ m = \dfrac{-11}{6}$

The equation of a line is

$( y -y_0) = m (x - x_0)\\\\( y -6) = \dfrac{-11}{6} (x+4)\\\\6( y -6) = (-11) (x+4)\\\\6y -36 = (-11x +44)\\\\11x +6y - 80 = 0$

Hence, the equation is 11x +6y - 80 = 0

Evaluate the function at the indicated values. f(x)= 6x^2+ 5x -12

seropon [69]

Step-by-step explanation:

We need to find the value of the function at the indicated value.

$f(x)= 6x^2+ 5x -12$

Indicated values are : f(-7), f(0), f(6), f(7)

To find f(-7), put x = -7 in the given function

$f(-7)= 6(-7)^2+ 5(-7) -12=247$

To find f(0), put x = 0 in the given function

$f(0)= 6(0)^2+ 5(0) -12=-12$

To find f(6), put x = 6 in the given function

$f(6)= 6(6)^2+ 5(6) -12=234$

To find f(7), put x = 7 in the given function

$f(7)= 6(7)^2+ 5(7) -12=317$

Hence, this is the required solution.
