Answer:
Step-by-step explanation: X and Y represent the digits.
The tens digit is twice the units digit.
The digit in the Tens place has 10× its base value, so we can set up equations to model the information given.
10x +y 10y +x are Original & Reversed numbers
X = 2y means the Tens digits is twice the units digit.
10y + x +2 = 10x +y - 34 models the statement: The reversed number plus two is 34 less than the original number.
Substitute 2y for x to solve for y
10y +2y +2= 10(2y) + y -34
Distribute and combine like terms
12y + 2 = 20y +y - 34
34 +2 = 21y -12y
36 = 9y Divide both sides to find the value of y.
4 = y
X = 2(4) Substitute 4 for y to find x
X = 8
Original number: 84 Reversed number: 48
Substitute into equation model
48 +2= 84 -34
50 = 50
True!

this is such a bad graph i honestly could not give you an exact answer
Answer:
if it's 2/3r^4 heres the answer
Step-by-step explanation:
1.) 2/3 times r raised to the 4th power
2.) the product of 2/3 and r raised to the 4th power
3.) 2/3 multiplied by r raised to the 4th power
4.) 2/3 of r raised to the 4th power
you can pick one of the many choices I've listed!! youre welcome :)
Sqrt55. Use the pythagorean theorem; 3^2 + x^2 = 8^2
