Step-by-step explanation:

no, because a square root is not a rational function, it is not a polynomial.

but the function has to be a fraction of 2 polynomials.

no matter what we do (we can e.g. multiply numerator and denominator by sqrt(x)), we cannot get rid of the square root in the overall function. we can move it up to the numerator and back down to the denominator, but it airways stays and converts at least one part of the fraction into simmering that is not a polynomial.

therefore, no.

Kelly is going two work two part-time jobs during the school year. When she works for her dad, she will make $8.00 per hour. Whe

finlep [7]

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of hours Kelly works for her dad per week and y represent the number of hours Kelly works in the daycare center per week.

Since she wants to make $84 per week, hence:

8x + 14y ≥ 84 (1)

Also, she can work a maximum of 10 hours per week, hence:

x + y ≤ 10 (2)

Using equation 1 and 2 and plotting the constraints on geogebra online graphing tool, the solution to the problem is at points:

A(0, 6), B(0, 10) and C(9.3, 0.7)

Answer these 6 questions

Dmitry [639]

Answer:

$1)13x - 15 = 12x + 16 \\ 13x - 12x = 15 + 16 \\ x = 31$

$2)9x - 19 = 2x - 5 \\ 9x - 2x = 19 - 5 \\ 7x = 14 \\ \frac{7x}{7} = \frac{14}{7} \\ x = 2$

$3)16x - 35 = 7x - 8 \\ 16x - 7x = 35 - 8 \\ 9x = 27 \\ \frac{9x}{9} = \frac{27}{9} \\ x = 3$

$4)6x - 5 = 13 - 3x \\ 6x + 3x = 5 + 13 \\ 9x = 18 \\ \frac{9x}{9} = \frac{18}{9} \\ x = 2$

$5)4x - 9 = 6 - x \\ 4x + x = 9 + 6 \\ 5x = 15 \\ \frac{5x}{5} = \frac{15}{5} \\ x = 3$

$6)5x - 2 = 10 - x \\ 5x + x = 2 + 10 \\ 6x = 12 \\ \frac{6x}{6} = \frac{12}{6} \\ x = 2$

hope this helps
