-5(y-15=3x) = -5y+75=-15x
add 15x to both sides and subtract 75 to both sides
-5y+15x=-75
5y-2x=-3
13x=-78
divide 13 to both sides
x=-6
y-15=3(-6)
y-15=-18
add 15 to both sides
y=-3
so the answer is (-6,-3)
I hope that this helped you sweetie :)
here if 20 degree angle is in base line then we would take sin of 20
because sin theta = height / hupotaneous
sin 20 = height/ 10
height = 10 times sin 20 = 10 times *0.34 = 3.4
But if angle 20 in on the line making height of the triangle then the base line of angle 20 degree would be the height of triangle )
we would take : cos 20 =base / hypotaneous
cos 20 = base / hypotaneous
cos 20 = base / 10
base = 10 cos 20 = 10 * 0.93 = 9.3
As per the given question if 20 degree angle lie on horizontal line answer should be 3.4
OR if angle 20 degree lie on vertical line then answer is 9.3
Answer:
-(3x^2 + 16x + 5)
-(3x+1)(x+5)
Step-by-step explanation:
-1(3x^2+15x+x+5)
-1(3x^2+16x+5)
-3x^2-16x-5
Answer:
46
Step-by-step explanation:
180 minus 105 minus 29
Answer:
The midpoint of MN is <u>(7,1)</u>
Add the x coordinates 7+7=14 then you divide that by 2 giving you 7.
Then you add the y coordinates together 6+(-4)=2 then divide by 2 and that gives you 1. Therefore the answer is (7,1)
