Answer:

x= -2, x = 5

Step-by-step explanation:

\sqrt{5x+11}-1=x

\sqrt{5x+11}=x+1

5x+11=(x+1)^2

5x+11=x^2 + 2x + 1

0=x^2 + 2x + 1-5x-11

0=x^2 -3x-10

0=(x+2)(x-5)

x= -2, x = 5

Rashon has a dimes and y nickels. He has no less than 12 coins worth at most $0.95
Soloha48 [4]

A possible solution of the system of inequalities is 5 dimes and, 8 nickels

<h3>How to determine a possible solution?</h3>

From the question, the given parameters are:

Number of coins = Not less than 12

Worth = At most $0.95

Represent dime with x and nickels with y

So, we have the following inequalities

x + y >= 12

0.1x +0.05y <= 0.95

Next, we plot the graph of the inequalities (see attachment)

From the graph, we have a possible solution to be (5, 8)

This is so because this point is in the shaded region

Becca and Kimberly are running at a constant speed in a marathon. Becca runs at 4.5 miles per hour. Kimberly’s progress is shown
Georgia [21]

Answer:

Part A: Kimberly

Part B:

Becca = 22.5 miles, Kimberly = 25 miles

Step-by-step explanation:

Part A:

Given that Becca runs at a constant speed of 4.5 miles per hour, use the table to find the constant speed that Kimberly runs, and compare who runs faster.

Let x = time

y = distance

k = speed = y/x

Equation for each person can be written as: y = kx

Therefore:

✔️Equation for Becca if k = 4.5

y = 4.5x

✔️Find k (speed) of Kimberly using (2, 10):

Speed (k) = y/x

k = 10/2

k = 5 miles per hour

Equation for Kimberly would be:

y = 5x

Comparing their speed, Kimberly runs faster because she covers more miles per hour than Becca does.

Part B:

For Becca, substitute x = 5 into Becca's equation, y = 4.5x

Thus:

y = 4.5*5 = 22.5 miles

For Kimberly, substitute x = 5 into Kimberly's equation, y = 5x

Thus:

y = 5*5 = 25 miles
