5x-2y=30 complete the missing value in the solution to the question (8, )
natali 33 [55]

Answer:

(8,5)

Step-by-step explanation:

5x-2y=30

lets substitute "8" as x and see where that takes us

5(8)-2y=30

40-2y=30

subtract 40 on both sides

-2y=-10

divide by "-2" on both sides

y=5

(8,5) is your answer

Find all constants a such that the vectors (a, 4) and (2, 5) are parallel.
Nezavi [6.7K]

Answer:

\displaystyle a = \frac{8}{5}.

Step-by-step explanation:

Two vectors (x_1,\, y_1) and (x_2,\, y_2) are parallel to one another if and only if the ratio between their corresponding components are equal:

\displaystyle \frac{x_1}{x_2} = \frac{y_1}{y_2}.

Equivalently:

\displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2}.

For the two vectors in this equation to be parallel to one another:

\displaystyle \frac{a}{4} = \frac{2}{5}.

Solve for a:

\displaystyle a = \frac{8}{5}.

\displaystyle \frac{8}{5} would be the only valid value of a; no other value would satisfy the \displaystyle \frac{x_1}{y_1} = \frac{x_2}{y_2} equation.
