The formula to finding a discriminant would be b^2-4ac, the b value of this trinomial being -5, the a value being 2, the c value being 3. Then, you plug the values in the equation and solve: (-5)^2-4(2)(3)
This would simplify to 1, meaning there are two solutions since the discriminant value is positive. If it is 0, there is one solution, if it is negative, then there are no real solutions.

because it says monthly fix cost and mothly means x
Answer:
x+3y = 6
or, x = 6-3y.................(1)
3x+5y =6..........(2)
Substituting x = 6-3y in equation (2),
3 (6 - 3 y)+5 y =6
or, 18 - 9y +5y=6
or, y = 3
x = 6 - 3y = 6- 3.-3 = -3
Hello!
For #1, the LCD is (A) 12 since both numbers go into 12 as their minimal number.
For #2, the missing number is (B) 4 because 1/4*4/4=4/16.
For #3, the answer is (B) 3 because you have to crossmultiply 20n(4*15) to find the answer.
for #4, the correct answer is (A) 4/5 is less than 5/6 because when converted into fractions with a common denominator, 24/30 is less than 25/30.
For #5, the LCD is 36; therefore, the answer is (A) because the fractions in the answer are properly converted to their new denominator.
I really hope I helped!
