Answer:
there are several methods to "solve a quadratic"
you can look them all up...
Graphing, factoring, completing the square, taking roots, quadratic formula are the common methods....
given the way you are asking the question I think that you are supposed to use the quadratic formula ..
please look at the image of the formula and
realize that you problem has
a=-1
b=2
c=6
just plug in those numbers into the formula and you will get the results in the "answer"
NOTE is written as ix ( )
Step-by-step explanation:
x= <u>-2+√ (2)²- (4)(-1)(-6) </u>
(2)(-1)
and
x= <u>-2-√ (2)²- (4)(-1)(-6) </u>
(2)(-1)
Answer:
it will be 90 i hope it weark
Step-by-step explanation:
1/2y - 2/3x= -2
1/2y = 2/3 x -2
2*(1/2y) = 2*(2/3 x) -2*2
y = (4/3)x - 4
Slope is 4/3.

Step-by-step explanation:
Answer:
No
Step-by-step explanation:
To solve this question,you will have to represent the variables with a specific letters so as to make the solving easier
Ok...let the soap be y and the lotion be x
2y+5x=20...(1)
6y+15x=50...(2)
Multiply (1) by 15
30y+75x=300...(3)
Multiply (2) by 5
30y+75x=250...(4)
If we should compare both (3) and (4) there is no way to eliminate any of these variables... because to solve this problem we will have to use elimination methods
Therefore it is not possible to get the actual price of any of them that is the soap and the lotion
