Find the values of x and y in the picture. Express answers in simplest radical form. (square root form)
Ilia_Sergeevich [38]

Answers:

x = 8

y = 15*sqrt(2)

===========================================================

Explanation:

This is a 45-45-90 triangle. The right triangle is isosceles.

This means the two legs 3x-9 and x+7 are the same length

3x-9 = x+7

3x-x = 7+9

2x = 16

x = 16/2

x = 8

If x = 8, then each leg is...

3x-9 = 3(8)-9 = 24-9 = 15

x+7 = 8+7 = 15

Each leg is 15 units long to help confirm we have the correct x value.

---------------

The hypotenuse y is exactly sqrt(2) times that of the leg length.

Therefore, y = 15*sqrt(2) since earlier we found each leg is 15 units long.

15*sqrt(2) = 21.213 approximately

A bank charges $0.25 per check and its monthly fees are $10. If Jerome issues 10 checks in a month, how much will a monthly chec
blsea [12.9K]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of checks.
 y: total cost.
 We now write the linear function that represents the problem.
 We have then:
 y = 0.25x + 10

 Then, Jerome issues 10 checks in a month.
 Therefore, we evaluate the function for x = 10.
 We have then:
 y = 0.25 (10) + 10

y = 2.5 + 10

y = 12.5
 Answer:
 
a monthly checking account will cost him about:
 
y = 12.5 $
