Which equation, when solved, results in a different value of x than the other three?

Mathematics
1 answer:
Ivahew [28]4 years ago
4 0

Answer:

  see below

Step-by-step explanation:

It is only necessary to compare the equations, not to solve them. The first three equations are equivalent, either because the terms were rearranged, or because they were all multiplied by -1.

The last equation is not equivalent, because some terms are multiplied by -8/7 and others are not. When different things are done on either side of the equal sign, it changes the equation, resulting in a different solution.

You deposit $50,000 in a savings account. After 10 years, your balance is $65,000. What is your interest rate?
otez555 [7]

Answer:

r = .03 or 3%

Step-by-step explanation:

Interest = Principal x Rate x Time

15000 = 50000(10)r

15000 = 500000r

r = 15/500

r = .03 or 3%

Does (5, 10)make the inequality y ≥ 10x+5 true
Salsk061 [2.6K]

Answer:

It is False.

Step-by-step explanation:

When you substitute the coordinates into the inequality equation :

y \geqslant 10x + 5

let \: x = 5,y = 10

10 \geqslant 10(5) + 5

10 \geqslant 55 \: (false)

Therefore, 10 isn't greater than 55.
