Use the equation sqrt4x +15 =3 sqrtx How many potential solutions are there

There is one solution

Step-by-step explanation:

sqrt(4x+15)=3(sqrt(x) )

divide each side by sqrt(x)

sqrt(4x+15)/sqrt(x) = 3

sqrt((4x+15/x)) = 3

square each side

(4x+15)/x = 3^2

(4x+15)/x = 9

multiply by x

4x+15 = 9x

subtract 4x on each side

15 = 5x

divide by 5

3=x

Have a Great night!

There is one potential solutions and no extraneous solutions. The solution to the equation is x = 3.

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
