How do functions work? Could someone explain how to know which questions are functions or not
belka [17]

Answer:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a speceified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x  equals 2.

Step-by-step explanation:

here is a step by step equation:

f(x) = x + 7

if:

x=2

then:

f(2) = 2 + 7 = 9

A function is linear if it can be defined by

f(x) = mx + b

Makes sense? Hope I helped

plus I'm in middle school learning this also.

What is the simplified expression for -3(2x- y) + 2y + 2(x+y)2
Step2247 [10]

Answer:

7y-4x.

Step-by-step explanation:

I think that the last 2 shouldn't be there and the third option should be 7y-4x or all the options are incorrect.

-3(2x- y) + 2y + 2(x+y)

= -6x+3y + 2y+2x+2y

= -6x+2x+3y+2y+2y

= -4x+7y.

If you are framing a photo that is 4in by 7 in, and you want the frame to be the same width all around, and the total area of th
aliina [53]

Answer:

<em>3.36in</em>

Step-by-step explanation:

The total surface area of the cardboard is expressed as;

TSA = 2(LW + LH + WH)

L is the length = 4in

W is the width

H is the height = 7in

TSA = 130in²

Substitute the given values into the formula and get the width W

TSA = 2(LW + LH + WH)

130 = 2(4W+4(7) + 7W)

130 = 2(11W+28)

130 = 22W+56

22W = 130 - 56

22S = 74

W = 74/22

<em>W = 3.36in</em>

<em>hence the width of the photo is 3.36in</em>
