Mira picked two numbers from a bowl. the difference of the two numbers was 4, and the sum of one-half of each number was 18. the system that represents mira’s numbers is below. x – y = 4 x + y = 18 which two numbers did mira pick? (10, 8) (18, 4) (20, 16) (40, 32)

 The correct option is (C) (20, 16).

Step-by-step explanation:  Given that Mira picked two numbers from a bowl. The difference of the two numbers was 4, and the sum of one-half of each number was 18.

We are to find the two numbers that Mira pick.

Let a and b be the two numbers that Mira pick.

Then, according to the given information, we have

From equation (i), we have

Substituting the value of x from equation (iii) in equation (ii), we get

Now, from equation (iii), we get

Thus, the two numbers that Mira pick are 20 and 16.

Option (C) is CORRECT.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
