Answer:
so x=5y

reciprocal of x=1/x then

sum of reciprocals means 1/x+1/y=2/5

subsitute x=5y for x in 1/x+1/y=2/5 and get

1/5y+1/y=2/5

multiply 1/y by 5/5 to make it 5/5y so you can add since the denomenators (bottom number) are the same

1/5y+5/5y=2/5

6/5y=2/5

multiply both sides by 5y

6=2y

divide both sides by 2

3=y

put this into x=5y so

x=5(3)

x=15

y=3

reciprocal of x=1/x then

sum of reciprocals means 1/x+1/y=2/5

subsitute x=5y for x in 1/x+1/y=2/5 and get

1/5y+1/y=2/5

multiply 1/y by 5/5 to make it 5/5y so you can add since the denomenators (bottom number) are the same

1/5y+5/5y=2/5

6/5y=2/5

multiply both sides by 5y

6=2y

divide both sides by 2

3=y

put this into x=5y so

x=5(3)

x=15

y=3

What is the answer to 2x >/= -6 + x-1<0 ?

hich function is the same as y = 3 cosine (2 (x + StartFraction pi Over 2 EndFraction)) minus 2? y = 3 sine (2 (x + StartFraction pi Over 4 EndFraction)) minus 2 y = negative 3 sine (2 (x + StartFraction pi Over 4 EndFraction)) minus 2 y = 3 cosine (2 (x + StartFraction pi Over 4 EndFraction)) minus 2 y = negative 3 cosine (2 (x + StartFraction pi Over 2 EndFraction)) minus 2

Which operation should be completed first ? 36÷4×3-2

Dahlia is trying to decide which bank she should use for a loan she wants to take out. In either case, the principal of the loan will be $19,450, and Dahlia will make monthly payments. Bank P offers a nine-year loan with an interest rate of 5.8%, compounded monthly, and assesses a service charge of $925.00. Bank Q offers a ten-year loan with an interest rate of 5.5%, compounded monthly, and assesses a service charge of $690.85. Which loan will have the greater total finance charge, and how much greater will it be? Round all dollar values to the nearest cent.a. Loan Q’s finance charge will be $83.73 greater than Loan P’s. b. Loan Q’s finance charge will be $317.88 greater than Loan P’s. c. Loan P’s finance charge will be $20.51 greater than Loan Q’s. d. Loan P’s finance charge will be $234.15 greater than Loan Q’s.

**Answer:**

multiplicative inverses

6 ≤ 4 + (-2x)

6 (-4) ≤ 4 - 2x - 4

4 and 4 cancels out

2 ≤ -2x

-1≥x

When you divide by a negative number, the inequality sign turns to the other side.

6 (-4) ≤ 4 - 2x - 4

4 and 4 cancels out

2 ≤ -2x

-1≥x

When you divide by a negative number, the inequality sign turns to the other side.

You should collect the variable on the left side since you can't have two variables of the same letter on each side.so you would take the variable from the right side and subtract it from the left. So subtract x on both sides. Your new problem is 2x-10 is greater than or equal to 0. Now you add 10 on both sides. Your new problem is 2x is greater than or equal to 10. Now divide by 2 on both sides. Your answer would be x is greater than or equal to 5

Well if one pound of yogurt cost 55 (cents?)

Two yogurts cost $1.10

Three yogurts cost $1.65

Four yogurts cost $2.20

Five yogurts cost $2.75

And finally...

Six yogurts cost $3.30

Hope this helps!

-7nx + 2nx + 2n + 7x ...combine like terms

-5nx + 2n + 7x

-5nx + 2n + 7x

5nx+2n+7x which is combined like terms all you do is cut the problem down.

2w-3>14

Try to follow my steps:

1). Copy the problem:
