Part A: 6 and 4x are the two factors because the initial equation was 30+20x but they factored out a 5 from both 30 and 20 to make the new equation
Part B:there are 3 terms in this expression
Part C:The coefficient of the variable X is 4

The sum of 2 and the quotient of 3 and y
Answer:
y = -3x - 27
Step-by-step explanation:
0 = -3[-9] + b
-27 = b
y = -3x - 27

The answer is not infinity.
<span>Consider FBDs of each mass with the direction of motion of m1 as positive </span>
<span>m1*g-T=m1*a </span>
<span>T-m2*g=m2*a </span>
<span>assuming mass less cord and mass less, friction less pulley </span>
<span>the accelerations are equal </span>
<span>a=(T-m2*g)/m2 </span>
<span>m1*g-T=m1*(T-m2*g)/m2 </span>
<span>do some algebra </span>
<span>m1*g-T=m1*T/m2-m1*g </span>
<span>2*m1*g=T*(1+m1/m2) </span>
<span>2*m1*m2*g=T*(m2+m1) </span>
<span>2*m1*m2*g/(m2+m1)=T </span>
<span>now take the limit of T as m1->infinity </span>
<span>T=2*m2*g </span>
<span>this is intuitively correct since the maximum acceleration of m1 is -g, the cord transfers the acceleration to m2, which is being acted on by gravity downward and an upward acceleration of g. Therefore the maximum acceleration of m1 is 2*g upward. </span>
Answer:
19.2 in. or 48000 feet (based on the scale)
Step-by-step explanation:
divide 6 by 2 and multiply by 100 (because that's the scale). You should get 300. Then, divide 3.2 by 2 and multiply by 100. You should get 160. Then, because the area would be 300*160, your answer is 48000
