Question 13 I don’t know how to do it
Gekata [30.6K]

Answer:

y = - \frac{1}{4} (x - 1)²(x + 2)(x + 6)

Step-by-step explanation:

The roots from the graph are

x = - 6 , then factor is (x + 6)

x = - 2 , then factor is (x + 2)

x = 1 ( multiplicity 2 ) , then factor is (x - 1)² then

y = a(x - 1)²(x + 2)(x + 6) ← a is a multiplier

To find a substitute any point on the graph into the equation

Using (0, - 3 ), then

- 3 = a(- 1)²(2)(6) = 12a ( divide both sides by 12 )

- \frac{1}{4} = a

Then

y = - \frac{1}{4} (x - 1)²(x + 2)(x + 6)

Answer:

9+x< -17

(make sure there's a line under the less than sign to make it work to)

Step-by-step explanation:

the product of 9 and x describes an addition problem, so it would be 9+x. after you put the less then or equal to sign and then -17.

Hope this helps

Drawing Conclusions: Geometry
leonid [27]
AE and EC are congruent because it's given that E is the midpoint of AC. However, DE and EB cannot be congruent because it does not state that point E is the midpoint of DB.

You cannot assume that all the triangles DEA, AEB, BEC, and CED are all congruent just from being given that E is the midpoint of AC. You would need to be given other information such as "Quadrilateral ABCD is a parallelogram. "
