Answer:
(9, 9)
Step-by-step explanation:
midpoint of (-4,15) and (22,3)

I think the average spend is 11 km. i don't know for sure..
Answer:
0=0
Step-by-step explanation:
6(2x+4)=4(3x+6)
Step 1: Simplify both sides of the equation.
6(2x+4)=4(3x+6)
(6)(2x)+(6)(4)=(4)(3x)+(4)(6)(Distribute)
12x+24=12x+24
Step 2: Subtract 12x from both sides.
12x+24−12x=12x+24−12x
24=24
Step 3: Subtract 24 from both sides.
24−24=24−24
0=0
When the car is moving, it has Kinetic Energy. As soon as the car entercount with the spring, its Kinetic Energy will transfer to Elastic Potential Energy.
<span>KE = EPE </span>
<span>1/2mv^2 = 1/2kx^2 </span>
<span>change the speed into m/s </span>
<span>50 km/hr = 13.9 m/s </span>
<span>1/2(1200)(13.9)^2 = 1/2k(2.2)^2 </span>
<span>now you do the math to solve for k.
k= 115926/2.42
K= 47903.30</span>
