Answer:

y=40

Step-by-step explanation:

A direct variation is a relationship between two numbers where the output equals the input times a constant.

The equation for a direct variation can be written as

y=kx

We can figure out the y value of the second coordinate by finding out what the constant (k) is. We can do that by plugging in the first coordinates into the equation.

y = kx

10 = 6k

10/6 = k

We can solve for y by plugging this constant, and the second coordinate into the equation.

y=kx

y=10/6(24)

y=40

IRISSAK [1]

Answer:

A = 7.7

b = 26

Step-by-step explanation:

$(3.5 \times 10^{16})(2.2 \times 10^{10}) = A \times 10^b \\ 3.5 \times 2.2 \times 10^{16} \times 10^{10}= A \times 10^b \\ 7.7 \times {10}^{16 + 10} = A \times 10^b \\ 7.7 \times {10}^{26} = A \times 10^b \\ equating \: like \: terms \: on \: both \: sides \\ A = 7.7 \\ 10^b = {10}^{26} \\ \implies \: b = 26$
