So see if u can factor out the trinomial.
it's factorable.
(x+3)(×-2)
so divide that factors by (×-2)
(×-2)(×+3)
---------
(×-2)
the (×-2) cancel out, leaving x+3
Answer:
30 students
Step-by-step explanation:
3 students = 10% of the class.
x students = 90% of the class.
(If more, less divides. Let x be the subject. Since we know 10% of the class already, we have to find the remaining 90% that is 100% - 10% = 90%.)
x = 90%/ 10% × 3 students. ( the percentage signs cancel out and so do the zero's.)
x= 9/1 × 3 students ( 9/1 is the same as 9)
x= 27 students
(To find the total, you must add the 10% of the students to the remaining 90% of the students in the class.)
Total number of students in the class = 27 students + 3 students
= 30 students
Answer:To get the graph of the given parabola, we will use the equation of the parabola to check if given points in options are lying on that parabola or not. If they lie on the graph of parabola, then they would satisfy the equation, else not. We will use vertex form of parabola to get its vertex.
Thus, by below shown calculations, we have
Option A: On a coordinate plane, a parabola opens up. It goes through (-6, 0), has a vertex at (-2, -8), and goes through (2,0)
For #2 you would count how many where the red dashed line is! Which is 3! Then you would count where the blue dashed line is! Which is 4! So then it would be 4/3(4 over 3) For the slope! Hope this helps! :)
