Multiply the first equation by -2 to eliminate a variable so it becomes:
-12x+8y=48
4x-8y=-32
Add them together.
-8x=16
x=-2
Plug it in one equation.
6(2)-4y=-24
12-4y=-24
-4y=-12
y=3
Ordered pair is: (-2,3)
Answer:
C 117
Step-by-step explanation:
<2 = 63
<4 = <2 vertical angles
<4 + <7 = 180
63 + <7 = 180
subtract 63 from each side
<7 = 117
Answer: The sphere is 0.002548 cm travel up the plane.
Step-by-step explanation:
Since we have given that
Inclination angle = 30°
Translational speed = 0.25 m/s
As we know that
and
Length of solid sphere is given by
So, it becomes,
And
So, it becomes,
Hence, the sphere is 0.002548 cm travel up the plane.
The answer would be -2
(4-10)-(8 ÷(-2))
(-6)-(-4)
-6+4
-2
Answer:
a = 9
Step-by-step explanation:
a+11=20
Subtract 11 from each side
a+11-11 = 20-11
a = 9
