Answer two questions about equations a and b a) x/4 +1 = -3
b) x+ 4 = -12

PART 1-

How can we get equation B from equation A?
Choose one
A) rewrite one side (or both) using the distributive property

B) Rewrite one side (or both) by combing like terms

C) Multiply/divide only one side by a non-zero constant.

D) Multiply/divide both sides by the same non-zero constant.

PART 2:
-based on the previous answer, are the equations equivalent? in other words, do they have the same solution?

Choose One

A) Yes
B) No

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

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:
