Make them common denominator
3/5 = 6/10
1/2 = 5/10
6/10 + 5/10 = 11/10 = 1 1/10
Answer:
The discriminant of the quadratic equation is 0
Step-by-step explanation:
Here, we want to calculate the discriminant of the given quadratic equation
Mathematically, we have the discriminant calculated by the following formula;
D = b^2 - 4ac
where;
b represents the coefficient of x which is -2
a is the coefficient of x^2 which is 1/7
c is the last number which is 7
Substituting these values;
D = (-2)^2 -4(1/7)(7)
D = 4 - 4
D = 0
Answer:
Step-by-step explanation:
Y = -1/4x+6, when y= 4
Same as saying
4 = -1/4x+6 , where y = 4
Multiply both sides by (4x+6)
4(4x+6) = -1
Opening the parentheses
16x + 24 = -4
16x = -4-24
16x = -28
Divide both sides by 16
X = -28/16
X = - 7/4
Ans = -7/4
