To solve the inequality, you need to isolate/get the variable "x" by itself in the inequality:

-4x < 20      Divide -4 on both sides to get "x" by itself

\frac{-4x}{-4}   when you multiply/divide a negative number to both sides of the inequality, you have to flip the inequality sign

x > -5

Your answer is the 4th option

What is the solution for x in the equation -4x+5x-7=10+3x-2x
jarptica [38.1K]
You combined the x’s together then u wanna move all the x’s to one side then after that you would want to do the opposite of -7, so then you add 7 to 10 and then you would divide everything by 2 and get x=8.5

Find the difference:
VLD [36.1K]

Answer: The difference cannot be found because the indices of the radicals are not the same.

Step-by-step explanation:

To find the difference you need to subtract the radicals. But it is important ot remember the following: To make the subtraction of radicals, the indices and the radicand must be the same.

In this case you have these radicals:

\sqrt[ {8ab}^{3} ]{{ac}^{2} }- \sqrt[ {14ab}^{3}]{{ac}^{2} }

You can observe that the radicands are the same, but their indices are not the same.

Therefore, since the indices are different you cannot subtract these radicals.

14. Veronica is choosing between two health clubs.
trapecia [35]

Answer:

The total cost for  each health club would be the same after 4 months.

Step-by-step explanation:

Answer:

The total cost for  each health club will be the same after 4 months.

Step-by-step explanation:

For studio A:

Membership fee = $22.00

Monthly Fee = $24.50

The equation for studio A:

  • A = 22 + 24.5x

For studio B:

Membership fee = $47.00

Monthly Fee = $18.25

The equation for studio B:

  • B = 47 + 18.25x

Let 'x' be the month of membership

We must have to find the value of month or 'x' for which the total cost at each health studio is the same.

i.e. when A = B

Hence, the expression will be

A = B

22 + 24.5x = 47 + 18.25x

Please note that if we put x=4, the L.H.S and R.H.S of the equations become the same

i.e.

22 + 24.5(4) = 47 + 18.25(4)

      22 + 98 =  47 + 73

         120 = 120

so, at x=4 the equations become the same.

Therefore, the total cost for  each health club would be the same after 4 months.
