Step-by-step explanation:
question 4
y=2x^2-5x+9
y= 2x^2+5x-1
y= 2x^2-5x+9=2x^2+5x-1
x=1
y= 2×1^2+5×1-1
y=6

Step-by-step explanation:
Since there are six groups of student and each group consists of 3 students, therefore, the total number of students is 18. All of them sold 162 balloons. In order to know how many balloons each student sold, we just have to divide 162 by 18 and the answer is 9. Hope this answers your question.

Ok let’s start off easy, the x and y stand for the missing number once you find those missing numbers you chose if the problems both used a same number if so it’s equivalent.if you had to use different numbers to get the answer it would be inconsistent and if you used even numbers to get the even answer than it would be consistent.i hoped that helped!
