Answer:

y = -3x - 2

Step-by-step explanation:

Step 1: State what is known

Slope = m = -3

y-intercept = b = -2

Step 2: Substitute information into y = mx + b

y = (-3)x + (-2)

y = -3x -2

Therefore the equation in slop intercept form is y=-3x-2

Answer:

Step-by-step explanation:

Replace m with -3, which is the slope

replace b with -2, = y-intercept into the equation y=mx+b.

$m = -3\\y - intercept = -2\\Slope\: intercept \: form :\\y =mx+c\\y = -3x-2$

Function p gives the perimeter of an equilateral triangle of side length s. It is represented by the equation p(s)=3x

babunello [35]

Answer:

A) p(s) means that the perimeter of the triangle is 60 units.

B) A value to make the equation true is s = 20

Step-by-step explanation:

In the equation p(s) = 60, 60 represents the perimeter of the equilateral triangle.

To find a value of s that makes the equation p(s) = 60 true, plug in 60 as p(s) and solve for s.

p(s) = 3s

60 = 3s

20 = s

So, s = 20 will make the equation true

I need help on this asap i'll give you so many points!!

Ierofanga [76]

So. The total of the interior angles of a triangle, are equal to 180°. So...add them together, and solve for X.

30x+60=180
30x=120
x=4

The distance adjacent to the smallest angle is the smallest.

Carrie=70°
Nayla=87°
Maria=23°

So...the distance across from Maria.

Carrie and Nayla are closest to each other.
