I need help, I don’t understand how to do this
torisob [31]

ANSWER:

                 m∠1 = 60°

                 m∠2 = 60°

                 m∠3= 120°

EXPLANATION:

The purple arrows indicate that side are parallel, so we know that that triangle NMP is the same as triangle NOP. If they are they same then we know that ∠1 and ∠2 equal 60° since the opposing angles equal 60°.

For ∠3 we look at the opposing angle and now know it is 60°. Since ∠3 and the opposing angle make a straight line which equals 180°. We can figure out ∠3 by subtracting 60 from 180 = 120°.

Find the equation of the linear function represented by the table below in slope intercept form
7nadin3 [17]

Answer:

the slope is "1"

the y-intercept is "5"

y = x + 5

Step-by-step explanation:

In order to find the slope, we use the slope formula with any pair of points, for example: (1, 6) and (3, 8):

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

in our case:

slope = (8 - 6) / (3 - 1) = 2/2 = 1

then the slope is "1".

Now we write the general "slope-intercept" equation of a line using the slope we found:

y = m x + b

y = 1 x + b

and now use one of the points (for example (3, 8) to find the intercept "b":

(8) = 1 (3) + b

8 - 3 = b

b = 5 (y intercept)

Then the equation of the line can be written as:

y = x + 5

I need to know where to put it on the number line! Please help ​
mina [271]

Answer:

Graph uploaded!

Step-by-step explanation:

<u>First, let's simplify the inequality before graphing it on the line.</u>

  • 2x + 4 < 8
  • => 2x < 8 - 4
  • => 2x < 4
  • => x < 2

<em>Now, let's graph it on the line. Please consider looking at my graph.</em>

Hoped this helped!
