Answer:
No, (8, -3) is not a solution.
Step-by-step explanation:
2x + 3y = 12
(substitute the variables for the point; x = 8 & y = -3)
2(8) + 3(-3) = 12
16 - 9 = 12
7 ≠ 12
Find the circumference to see how much of the wheel is touhing the ground
c=2pir
c=2pi1.9
c=2.8pi
2.8pi=distance per 1 rotation
number of rotations per second times 2.8pi=12feet per second
dvide both sides by 2.8pi
number of rorations per second=12/2.8pi
number of roations per second=6/1.4pi
number of roations per second=3/0.7pi
number of roations per second=30/7pi
aprox
number of roations per second=1.364 rotations per second
Answer:
12x+3y+3
Step-by-step explanation:
Let's simplify step-by-step.
4x+2y+6+7x+3y−4+x−2y+1
=4x+2y+6+7x+3y+−4+x+−2y+1
Combine Like Terms:
=4x+2y+6+7x+3y+−4+x+−2y+1
=(4x+7x+x)+(2y+3y+−2y)+(6+−4+1)
=12x+3y+3
