What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

A ratio shows us the number of times a number contains another number. The value of x in the given expression can be found using the ratios. Therefore, The value of x makes this proportion true 3/x=15/40 is,

3 / x = 15 / 40

3 × 40 = x × 15

120 = 15x

x = 120/15

x = 8

Hence, The value of x makes this proportion true 3/x=15/40 is 8.

Answer 2

Answer: If you would like to solve the equation 3 / x = 15 / 40 for x, you can calculate this using the following steps:

3 / x = 15 / 40 /*x
3 = 15 / 40 * x /*40
3 * 40 = 15 * x /15
x = 3 * 40 / 15
x = 8

The correct result would be 8.

The image of a parabolic mirror is sketched on a graph. The image can be represented using the function y = x2 + 2, where x represents the horizontal distance from the maximum depth of the mirror and y represents the depth of the mirror as measured from the x-axis. How far away from the maximum depth is a point on the mirror that is inches in depth? 3 inches 4 inches 5 inches 6 inch

Answers

The equation of the parabola is
y = x2 + 2
where x represents the horizontal distance from the maximum depth of the mirror and y represents the depth of the mirror as measured from the x-axis

We are asked to solve for the distance from the center of the parabola or simply the value of y given a value of x of 2 inches.

Substituting:
y = 2^2 + 2
y = 6 inches

its not 6 i put that and got it wrong
