Answer:
(x1,y1)=(−2,2)
(x2,y2)=(0,−2)
Use the slope formula:
m=
y2−y1
/x2−x1
=
−2−2
/0−−2
=
−4
/2
=−2
Answer:
m=−2 This is the slope
So,the slope intercept form for 2 points is y-y1=m(x-x1) m=slope
y-y1=m(x=x1)
y-2=-2(x-(-2) ( - and - is +) So,the final equation is:
y-2=-2(x+2)
I hope this help you :)
Answer:
60 km
Step-by-step explanation:
The closure speed of the trains is 30+30 = 60 km/h. Since their initial distance apart is 60 km, it will take 1 hour for them to collide.
The bird flies for 1 hour at 60 km/hour, so flies a total distance of 60 km before being crushed in the collision.
Answer:
125°
Step-by-step explanation:
ABC + CBD = 180
(Supplementary angles)
8x - 41 + 9x + 17 = 180
17x = 204
x = 12°
CBD = 9(12) + 17 = 125°
Answer:
x=9
y=12
Step-by-step explanation:
. Substitute the given value of x into the equation so... -5(2y-15)+4y=3
. y=12
. Substitute the given value of y into the equation x=2y-15 so... x=2 x 12-5
. x=9
.The possible solution of the system is the ordered pair (x,y) so... (x,y)=(9,12)
