Answer: 2 log y - log 25

<u>Step-by-step explanation:</u>

Notes: Division expands to subtraction.  Exponent expands to multiplication.

log\bigg(\dfrac{y}{5}\bigg)^2\\\\\\=log\bigg(\dfrac{y^2}{5^2}\bigg)\\\\\\=log(y^2)-log(5^2)\\\\\\=\large\boxed{2log(y)-log(25)}

A. Use the points (5, 1273) and (10, 2546) to write an equation for the line.
pantera1 [17]

Using the points (5, 1273) and (10, 2546), equation for the line is 5y =  1273x.

<h3>Define equation.</h3>

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.

Given,

Coordinates (5, 1273) and (10,2546)

For slope, m

m = y₂ - y₁/ x₂ - x₁

m = 2546 - 1273/10 -5

m = 1273/5

Equation in y = mx form,

y = 1273/5 x

Cross multiplying,

5y =  1273x
