PSYCHO15rus [73]

Answer:

the angle is 245°

Step-by-step explanation:

that is a pentagon, (a shape with 5 sides)

we know 4 of the angles in the pentagon

the sum of those 4 angles is

58°+100°+112°+25°=295°

to find a shapes total amount of °, the equation is (n-2)x180°

(5-2)x180°

=540°

540°-295°=245°

x=245°

Write the slope-intercept form of the equation for the line.
umka21 [38]

Answer:

y = (- 7/8)*x - 1.5

Step-by-step explanation:

One point is (-4,2) and the other one is (4,-5)

The first step is to find the slope.

m = (y2 - y1) / (x2 - x1)

  • y2 = 2
  • y1 = -5
  • x2 = -4
  • x1 = 4

Solution

<em><u>Find the slope</u></em>

m = (2 - - 5) / (-4 - 4)

m = (2 + 5) / (- 8)

m = 7 / - 8

So far what you have is y = (-7/8)x + b

Find the y intercept.

Use (4,-5)

y = (-7/8)x + b

x = 4

y = - 5

-5 = (-7/8) * 4 + b

-5 = -7/2 + b

-5 = - 3.5 + b                    Add 3.5 to both sides.

-5 + 3.5= - 3.5+ 3.5 + b

- 1.5 = b

The graph of y = x^3 -9x^2 - 16x +1 has a slope of 5 at two points. Find the coordinates of the points.
Troyanec [42]
We are given with the equation y = x^3 -9x^2 - 16x +1. It is said that when the slope is 5, there are two points tangent to the graph. the slope is equal to the y'.y' = 3x2 -18x -16 = 5     3x2 -18x - 21 = 0x1 = 7 and x2 = -1The two points are (7,-209) and (-1,7)
