Answer: 0
Step-by-step explanation:
We know that if the number of real solutions the quadratic equation depends on the discriminant:-
- If d = 0, then equation will have exactly one real number solution .
- If d > 0 then equation will have exactly two real number solutions.
- If d < 0 then the quadratic equation will have no real solutions. There will be two complex number solutions.
Therefore, if a quadratic equation has exactly one real number solution.
Then, the value of its discriminant= 0.
Y = mx + b
slope(m) = 7
(5,30)...x = 5 and y = 30
now we sub and find b, the y int
30 = 7(5) + b
30 = 35 + b
30 - 35 = b
-5 = b
so ur equation is : y = 7x - 5 <==
The answer would be D) x = 11.
Add 5 to both sides (5x = 50 + 5)
Simplify 50 + 5 to 55 (5x = 55)
Divide both sides by 5 (x = 55/5)
Simplify 55/5 to 11 (x = 11)
