Ihave no idea how to do these problems. i keep on getting them confused somehow. a sista out! ❤️

You use the process of substitution to solve these problems

2y = 4x + 12 simplify

y = 2x + 6

now why can be plugged into the second equation

2x - (2x + 6) = -6

2x - 2x - 6 = -6

-6 = -6

therefore x is zero

plug it in

2y = 0 + 12

y = 6

what we realize though is

2y = 4x + 12

y = 2x + 6 (multiply by two to receive 2y = 4x + 12)

They are the same graph so there are infinite solutions but plugging in (-4,2) shows it is not a solution.

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
