Paladinen [302]3 years ago
6 0

Answer:

17 degrees.

Step-by-step explanation:

Total sum of angles on a triangle always make 180

112+51=163

180-163=17

Mrac [35]

Answer:

Missing Value Is 4 .

Step-by-step explanation:

According To The Question, We Have

  • A model with 4rows*4squares & 4rows*7squares

        Equation is 16+28 = X*(4+7)

        Solve the above Equation, We get 44=X*11 ⇔ X=4

Hey can you help me fast I am at a 83 and I need to get to a 90 on this.
jeyben [28]

Answer:

2/5

Step-by-step explanation:

First by looking, you have a slope going upward to the right so it is a positive slope.

Two points on the line that seem to go directly through the grid at the intersection points are ( -60, -90) and ( 40, -50).

Slope is Rise (y axis) over the Run (x axis).  The numbers above have x first and y second.

So the rise is the total distance between -90 and -50 which is 40.

The run is the total distance between 40 and -60 which is a total of 100.

It takes 40 units to get back to the 0 mark on the x axis and the another 60 units to get to the -60 point.

So you slop is 40/100.  You can simplify this down to 4/10 or even further to give you 2/5.

Slope Intercept Form And Equations From Graphs
r-ruslan [8.4K]

Answer:

1. Choice B

2.  Choice C

3.  X=-2

4.  Choice A

5. y = 5/2 x + 5

Step-by-step explanation:

1.  

   the slope is down 3 over 2     m =-3/2

point slope form

y-y1= m (x-x1)

y-y1 = -3/2 (x-x1)

Choice B


2.  (-3,-1)  (1/2,2)

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

m=(2--1)/(1/2--3)  = (2+1)/(1/2+3) = 3/(3.5) =  multiply top and bottom by 2

  m = 6/7

point slope form

y-y1 = m(x-x1)

y--1 = 6/7 (x--3)

y+1 =6/7 (x+3)

multiply by 7

7y+7 = 6(x+3)

7y+7 = 6x+18

subtract 7y from each side

7 = 6x-7y+18

subtract 18 from each side

-11=6x-7y

Choice C


3.  x=-2

This is a vertical line, the value of x never changes


4.   (-1,2) (1,-4)

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

      = (-4-2)/(1--1) = -6/(1+1) = -6/2 = -3

point slope form

y-y1 = m(x-x1)

y-2 = -3(x--1)

y-2 = -3(x+1)

y-2 = -3x-3

add 2 to each side

y = -3x-1

Choice A


5.  (-2,0)  (0,5)

the y intercept is 5

slope is change in y over change in x

slope =(y2-y1)/(x2-x1)  = (0-5)/(-2-0) = -5/-2 = 5/2

slope intercept form

y= mx+b

y = 5/2 x + 5
