find the x- and y-intercept of the line. 5x – 4y = 40 a. x-intercept is –4; y-intercept is 5. b. x-intercept is –10; y-intercept
pashok25 [27]
5x - 4y = 40

x intercept is when y = 0

5x - 4*0 = 40

5x = 40

x = 40/5

x = 8             x intercept = 8

y intercept is when x = 0

5*0  - 4y = 40

-4y = 40

y = 40/-4

y = -10

y intercept = -10


x intercept = 8, <span>y intercept = -10</span>

Help me really quick
kati45 [8]

If you can't figure out how to do it, you can always use your answer choices, so for example, use choice a (21 degrees). Plug in 21 for x for both equations. So for the first equation that would be 7(21)-1= 146 and second equation 3(2)-9= 54. Then you would add the results, 146+54=200. In that case, choice 21 is wrong because both of these angles should equal to 180 since it is a supplementary angle. I hope that helped.

Answer please need belp ???
Stells [14]
Since a triangles angles add up to 180 you would add the other sides and then
180-161=19
So angle 1 is 19 degrees
