Step-by-step explanation:
The area A of the tire in contact is 7"×5" = 35 sq inches and we know that each tire has a pressure of 30 psi so the weight of the car in tons is
Hey!
Our point slope formula is y-y1 = m(x-x1)
Therefore, we can plug our values from the slope and the set of points.
We have:
y-7 = -3/2(x--4)
Subtracting a negative is the same thing as adding, so we have:
y-7 = -3/2(x+4)
Hope this helps!
<h2>Intersection and Union of Sets</h2><h3>
Answer:</h3>
<h3>
Step-by-step explanation:</h3>
Given:
The Union (
) of sets 
and 
is just a set containing all the elements of sets and . However, elements that are present in both sets should not repeat in the Union of Sets as the elements of a set should distinct be from each other.
Part i:
The Intersection (
) of sets and is just a set containing all the elements that are both present in sets and .
Part ii:
Part iii:
<span>1/2+(-2/3)
Multiply until both fractions have the same common denominator
3/6 - 4/6
Subtract the numerator but NOT the denominator
Final Answer: -1/6</span>
<span>The nonpermissible replacement is when the denominatory equals zero. In this case, when x=-.5, the denominator equals zero. Therefore, -.5 is the nonpermissible replacement. </span>
