The maximum air pressure is 43 pounds per square inch  and the minimum air pressure is 41 pounds per square inch

The minimum air pressure is the least amount of air pressure that must be in the tire. The maximum air pressure is the greatest amount of air pressure that must be in the tire.

In order to determine the minimum air pressure, I would subtract the range of air pressure that can be allowed in the tire from the recommended pressure.

recommended pressure -  range of air pressure

41 - 2 =  39 pounds per square inch.

In order to determine the maximum air pressure, I would add the range of air pressure that can be allowed in the tire from the recommended pressure.

recommended pressure +  range of air pressure

41 + 2 =  43 pounds per square inch

This can be summarised with the equation: 41 ± 2

A student worked out the following problem to find
polet [3.4K]
We have that

y=x²<span>+3x-5
</span>y=4x+1

using a graph tool
see the attached figure

the solution are the points
(-2,-7)
(3,13)

<span>the solution obtained by the student
</span>(-2,0)
(3,0)<span>
is incorrect because the values ​​of the coordinate y are incorrect
</span>the values of x are correct
x1=-2
x2=3

<span>with those values ​​of x obtained, the student had to substitute it in any of the two equations to obtain the value of y
</span>so
for x=3
y=4x+1------> 4*(3)+1-----> y=13

for x=-2
y=4x+1------> 4*(-2)+1-----> y=-7

I brought 16 packs of cola to a party and each pack had 8 cans. My friend brought 6 cans of juice. How many cans did they bring
umka2103 [35]
You would get 134 since you have to multiply 16 and 8 since 8 is the number of cans in a pack. then you add the 6 extra cans of juice

Susan and John are buying cold drinks for a neighborhood picnic. Each person is
givi [52]

Answer:

Susan has suggested a correct method to calculate the amount of money

Step-by-step explanation:

Here we must check what each person is calculating. First, we consider Susan's method. She has suggested that we multiply the cost per soda, that is dollars/soda by the number of sodas required, we get the total cost.

Assuming that 18 sodas are required and each costs $0.20, the total cost according to Susan is $3.60.

John suggests we divide the cost of a 12 pack of soda by the number of sodas required. Considering a 12 pack of soda costs $12 and the same amount of sodas, 18, are required, we get that each soda costs $0.66.

Looking at these answers, we see that Susan has suggested a correct method to calculate the amount of money needed to buy a number of sodas. John has suggested the amount each person would have to contribute if everyone at the party was trying to buy a 12-pack of soda; regardless of whether more or less than a 12-pack is required.

Tcecarenko [31]

The product of the expression (\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1}  is the expression \frac{2}{k+2}

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the expression:

(\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1} \\\\This\ can\ be\ simplified\ to:\\\\(\frac{2(2k+1)(k-2)}{(k+2)(k-2)(2k+1)}) \\\\=\frac{2}{k+2}

The product of the expression (\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1} is the expression \frac{2}{k+2}
