What is the value of x

Mathematics
2 answers:
Finger [1]2 years ago
8 0

Answer:

I. x=8

Step-by-step explanation:

lines form 180° angles so

140 +5x= 180 ; subtract 140 from both sides

5x= 180-140; divide both sides by 5

x= 40/5 = 8

Answer:

8

Step-by-step explanation:

Lines have angles that are equal to 180. Therefore, because we already have 140 of the 180 necessary, we can subtract 140 from 180 to get 40. 40 divided by 5 is 8.

Hope that this helps!

Can someone please help me with 19a?
Mila [183]

Answer:

d(t) = 60t

Step-by-step explanation:

When d = 0, t = 0 as well, so the y-intercept in 0. The slope of the line would be 60.

Hope this helps!

Factor k^2 +3x-10 .....
Svetach [21]

Answer:

I think you mean: x^2 + 3x - 10, then

x^2 + 3x - 10

= x^2 + 5x - 2x - 10

=x(x + 5)  - 2(x + 5)

=(x - 2)(x + 5)

Hope this helps!

write the linear equation from the given information in slope intercept form passing through (-2,8) and perpendicular to y=2x+5​
Leto [7]

Answer:

y  =  -\frac{1}{2} x + 9

Step-by-step explanation:

Given parameters:

  Coordinates = (-2,8)

Equation of the line  y  = 2x + 5;

Unknown:

Linear equation of a line perpendicular = ?

Solution:

From the given expression, a line perpendicular will have a negative inverse of the slope given.

           y  = 2x + 5

Equation of a line  is y = mx + c;

y and x are the coordinates

  m is the slope

   c is the intercepts

    y  = 2x + 5 ;

 The slope is 2;

  A line perpendicular will have a slope of -\frac{1}{2}  

 Since y = 8 and x  = -2, let us find c;

     8  = 2 x -\frac{1}{2}  + c

    8 = -1 + c

     c  = 8+1 = 9

The equation of the line is;

       y  =  -\frac{1}{2} x + 9
