Answer:

  y = -3x^2 +3x +6

Step-by-step explanation:

For roots p and q, the equation can be written as ...

  y = a(x -p)(x -q)

The value of 'a' must be determined so that the product <em>apq</em> is equal to the y-intercept. One could say that the formula is ...

  y = (y-intercept)/(pq)·(x -p)(x -q)

For your given values of p = 2, q = -1, y-intercept = 6, this becomes ...

  y = 6/(2(-1))(x -2)(x +1)

  y = -3(x^2 -x -2) . . . . . simplifying a bit

  y = -3x^2 +3x +6

WILL RATE BRAINLIEST !!!!!!!!     Which pair of triangles can be proven congruent by the HL theorem?
Fofino [41]

Answer: Its the third pair which can be proven by the HL theorem


Step-by-step explanation:

HL theorem states that if hypotenuse and one leg of two right triangles are congruent then the triangles are said to be congruent.

In first picture there is two right triangle with equal hypotenuse but not any leg. So HL theorem cannot be applied.

In second picture there is no right triangle. So HL theorem cannot be applied

In third triangle there is two right triangle with equal hypotenuse and legs therefore by HL theorem they are congruent.

In fourth picture they are not right angle. So HL theorem cannot be applied

The sum of two consecutive integers is 105 find the integers
zzz [600]

The integers are 52 and 53

<em><u>Solution:</u></em>

Consecutive numbers are numbers that follow each other in order. They have a difference of 1 between every two numbers

Let the two consecutive integers be x and x + 1

Given that, sum of two consecutive integers is 105

Therefore,

x + x + 1 = 105

Combine the like terms

2x + 1 = 105

2x = 105 - 1

2x = 104

Divide both sides of equation by 2

x = 52

Thus, another integer = x + 1 = 52 + 1 = 53

Thus the integers are 52 and 53
