2(x+a)^2+3(z+a)+1
2(x²+a²)+3z+3a+1
2x²+2a²+3z+3a+1
Since there aren't any like terms, you can't simplify it any more.
Answer:
Fish A is 4 inches.
Fish B is 5 inches.
Step-by-step explanation:
22=3a+2b
and
32=3a+4b
So,
a=4 and b=5
Answer: John has an object suspended in the air. It has a mass of 50 kilograms and is 50 meters above the ground. Calculate the object's potential energy.
Step-by-step explanation:
Calculate the potential energy for a 2 kg basketball dropping from a height of 3.5 meters with a velocity of 9.8 m/sec².
The solid line indicates that the line itself is included in the solutions. That the shaded area is to the left, or under, the line means that y≤the line.
To find the equation of the line you first find the slope or m using any two points.
m=(y2-y1)/(x2-x1) in this case you are given (2,-5) and (-2, 3) so
m=(3--5)/(-2-2)
m=8/-4
m=-2
So far for y≤mx+b we have:
y=-2x+b using either point we can solve for b, I'll use (2,-5)
-5=-2(2)+b
-5=-4+b
-1=b
So the line is:
y=-2x-1 and since y≤ the line:
y≤-2x-1
The answer for this is C.
