Which statement best explains why y=4−6x is a function? question 3 options: it is a linear equation. the slope is a factor of the y-intercept. each x value has one and only one y value. the solutions to the equation can be written as ordered pairs.

The correct answer option is: Each x value has one and only one y value.

Step-by-step explanation:

A relationship from a set of inputs to a set of outputs where each input has exactly one corresponding output value is said to be a function.

Here, we are given which happens to be a function as no x value is repeated and there is only one corresponding y value to it.

Therefore, option c is the correct answer.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
