You could buy 15 bags of mulch with $105.
To find the answer, plug in 0 for x since you aren't buying any bags of sand and then you have 7y=105 and divide by 7 to find y which is 15.

Answer:

The true statements:

The only value that is in the domains of both functions is 0.

The range of g(x) is all values less than or equal to 0.

==================================

Step-by-step explanation:

See the attached figure:

As shown: f(x) = √x with blue color

When f(x) is reflected across the x-axis the result will be (-√x) with red color.

Then the is reflected result across the y-axis to create the graph of function g(x) = -√(-x) with green color.

<u>Domain </u>of f(x) = [0,∞) & <u>Range</u> of f(x) = [0,∞)

<u>Domain </u>of g(x) = (-∞,0] & <u>Range </u>of g(x) = (-∞,0]

So, according to previous, we will check the statements:

1) The functions have the same range. <u>(Wrong)</u>

2) The functions have the same domains. <u>(Wrong)</u>

3) The only value that is in the domains of both functions is 0. <u>(True)</u>

4) There are no values that are in the ranges of both functions. <u>(Wrong)</u>

5) The domain of g(x) is all values greater than or equal to 0. <u>(Wrong)</u>

6) The range of g(x) is all values less than or equal to 0. <u>(True)</u>

0.12x - 1.5= 0.24x - 0.06
Sophie [7]

To solve this equation, lets move all of the variables to one side of the equation and the constants to the other.

0.12x - 1.5 = 0.24x - 0.06

Subtract 0.12x from both sides of the equation

-1.5 = 0.12x - 0.06

Add 0.06 to both sides of the equation

-1.44 = 0.12x

Divide both sides by 0.12 to isolate x

x = -12
