Write the linear system that corresponds to the given augmented matrix. use x 1x1 and x 2x2 to represent the terms from the first and second columns of the matrix, respectively. type the equation that corresponds to the first row in the first answer box, the equation that corresponds to the second row in the second answer box, and the equation that corresponds to the third row in the last answer box. 1 x 1 equals 71x1=7 nothing nothing (simplify your answers. type your answers in standard form.)

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
