Answer:

Option A. is the solution

Step-by-step explanation:

The equation of the line is y = - 9x + 4

We will plug in the values of each ordered pair given in the options. If they satisfy the equation, will be the solution of the eqaution.

Option A.

(10, -86)

-86 = - 9(10) + 4

-86 = -90 + 4

-86 = -86

Therefore, this ordered pair is the solution of the equation.

Option B.

(-4, -58)

-58 = -9(-4) + 4

-58 = 36 + 4

-58 = 40

Not the solution of the equation.

Option C.

(6, -41)

-41 = -9(6) + 4

-41 = -54 + 4

-41 = -50

Not the solution of the equation.

Option D.

(-6, 57)

57 = -9(-6) + 4

57 = 54 + 4

57 = 58

Not the solution of the equation.

a certain shade of blue is made by mixing 1.5 quarts of blue paint with 5 quarts of white paint. If you need a total of 16.25 ga

Law Incorporation [45]

we know the blue and white paints are on a 1.5 : 5 ratio, thus, if we have a total of 16.25 gallons of paint to be split along that ratio, we can simply divide 16.25 by (1.5+5) and distribute accordingly.

$\bf \cfrac{blue}{white}\qquad \stackrel{ratio}{1.5:5}\qquad \cfrac{1.5}{5}~\hspace{5em}\cfrac{1.5\cdot \frac{16.25}{1.5+5}}{5\cdot \frac{16.25}{1.5+5}}\implies \cfrac{1.5\cdot \frac{16.25}{6.5}}{5\cdot \frac{16.25}{6.5}} \\\\\\ \cfrac{1.5\cdot 2.5}{5\cdot 2.5}\implies \cfrac{3.75}{12.5}\qquad \qquad \boxed{\stackrel{blue}{3.75}~:~\stackrel{white}{12.5}}$
