Select the equation of the line parallel to y=-2x – 7 the equation and that passes through the point (3, 1).
O y=-2x-2
O y=-2x + 7
O y=-2x +6
O y = 3x -8
O None of the other answers are correct

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

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:

maya’s expression will generate the wrong sum because she violated the commutative property.

step-by-step explanation:

i suppose it should be (y=2x-5)
