 x -3y = 4  multiplie both sides by -2 => -2x +6y = -8 
2x +Qy = 8

-2x +6y = -8
 2x +Qy = 8
------------------ assume the same terms 
  0 6y +Qy = 0

6y +Qy = 0 

Qy = -6y  divide both sides by y and will get 

Q = -6

PLEASE HELP! What is the ratio of the volumes of two spheres, if the ratio of their radii is 13: 9
DiKsa [7]

Answer:

V_1 : V_2= 2197 : 729

Step-by-step explanation:

Let the volumes of both the spheres be V_1, \:V_2 and their radii be r_1, \:r_2 respectively.

\huge r_1 : r_2= 13 : 9 (given)

\implies\huge \frac{r_1}{r_2}= \frac{13}{9}.....(1)

\huge \frac{V_1}{V_2}=\frac{\cancel {\frac{4}{3} \pi} r_1^3}{\cancel {\frac{4}{3} \pi} r_2^3}

\huge \frac{V_1}{V_2}=\frac{ r_1^3}{r_2^3}

\huge \frac{V_1}{V_2}=\bigg(\frac{ r_1}{r_2}\bigg) ^3..... (2)

From equations (1) & (2), we have:

\huge \frac{V_1}{V_2}=\bigg(\frac{13}{9}\bigg) ^3

\huge \frac{V_1}{V_2}=\frac{2197}{729}

\huge \therefore V_1 : V_2= 2197 : 729

Thus, the ratio of the volumes of two spheres would be 2197 : 729.

Write an equation of the line that passes through the point (5,-4) and has a slope of 2.
Romashka-Z-Leto [24]

Answer:

Point slope formula: (y + 4) = 2(x - 5)

Slope intercept formula: y = 2x - 14

Step-by-step explanation:

Point slope formula: (y + 4) = 2(x - 5)

Slope intercept formula: y = 2x + b, -4 = 10 + b, b = -14

y = 2x - 14

Joseph needs to find the quotient of 3.216 ÷8. In what place is the first digit in the quotient?
ExtremeBDS [4]
If you do long division you will see that 8 cannot go into 3 it will go into 3.2 so the first digit will be in the tenths place 0.4... no need to finish the division since all the question asks is the place of the first digit
