Answer:

x^2-9x+8

Step-by-step explanation:

(2x^2-5x+3)-(-x^2+4x-5)

Open the bracket first

2x^2-5x+3+x^2-4x+5

Collect like terms

2x^2+x^2-5x-4x+3+5

x^2-9x+8

So the final answer is x^2-9x+8

2x - 3y = 12<br> x = 4y + 1
aliya0001 [1]

Answer:

x = 9, y = 2 is the solution of the given system.

Step-by-step explanation:

Here, the given set of equation is :

2 x - 3 y = 12

x = 4 y + 1

Now, from equation (2) we see that x = 4 y + 1.

Substitute the value of y from (2) in the first equation. we get:

2 x - 3 y = 12  ⇒ 2 (4 y + 1) - 3 y = 12

or, 8 y + 2 - 3 y = 12

or, 5 y = 12- 2  = 10

or, y = 10/ 5 = 2

or, y = 2

Now, x = 4 y + 1   ⇒ x  =  4(2)  + 1 = 8 + 1 = 9, or x = 9

Hence, x = 9, y = 2 is the solution of the given system.

you are filling your tire with air. the recommended pressure is 41 pounds per square inch. you read your owner's manual and find
emmainna [20.7K]

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
