If the value of a is negative, then the range will be (-∞, k) and if the value of the a is positive then the range will be (k, ∞).
<h3>What is a quadratic equation?</h3>
It's a polynomial with a worth of nothing.
There exist polynomials of variable power 2, 1, and 0 terms.
A quadratic condition is a condition with one explanation where the degree of the equation is 2.
Domain and range of linear and quadratic functions
Let the linear equation be y = mx + c.
Then the domain and the range of the linear function are always real.
Let the quadratic equation will be in vertex form.
y = a(x - h)² + k
Then the domain of the quadratic function will be real.
If the value of a is negative, then the range will be (-∞, k) and if the value of the a is positive then the range will be (k, ∞).

Answer:
ΔJLK≅ ΔMLN
Step-by-step explanation:
SSS
The problem is to find how many students have either blond hair or glasses and then divide that by the total number of students; that will find the probability.
Since 7 have blonde hair and 9 have glasses, that would be a total of 16 persons if there were no overlap; that is, no blonde wears glasses and nobody who wears glasses is a blonde.
But there are 4 persons who have both blond hair and wears glasses. That means, of the 7 who are blondes, 3 of them do not wear glasses. And, of the 9 who wear glasses, 5 of them are not blondes.
So we have 3 who are blondes without glasses, 5 who wear glasses who are not blondes, and 4 blonds with glasses, for a total of 12 persons.
The probability is, therefore, 12/26 or 6/13.
Answer:
3. B.
1. 3551.
Step-by-step explanation:
3. For two equations to have infinite solutions, the equations must be the same.
y = -5x + 6
5x + y - 6 = 0
Multiply the whole thing by 2.
10x + 2y - 12 = 0
B.
1. Michelle rides roller coasters 3 times and plays the super swing 5 times, which means that A = 3 and B = 5.
Marty rides the roller coasters 5 times and plays the super swing 1 time. That means C = 5 and D = 1.
So, your answer will be 3551.
Hope this helps!
