Answer:

I beleive X=2

Area is 24

Step-by-step explanation:

X=2 because the side with B has 4cm and on the other it has 6 but the 4 can be put into 6 and 6-4 is 2 if that made any sense

The area is 4 times 2= 8 and then 8 times 2 is 16

16+8=24

What is the equation in vertex form of the quadratic function with a vertex at (-1, -4) that goes through (1, 8)?

cestrela7 [59]

Answer:

y = 3(x+1)^2 - 4

Step-by-step explanation:The general form of the equation of a quadratic function whose vertex is (h,k) and whose leading coefficient is a is:

y - k = a(x-h)^2, or

y = a(x-h)^2 - k

Substituting the coefficients of the vertex (-1, -4), we get:

y = a(x + 1)^2 - 4

Substituting the coordinates of the given point, (1,8), we get:

8 = a(1+1)^2 - 4, which simplifies to:

8 = a(2)^2 - 4, or

8 = 4a - 4. Then 4a = 12, and a = 3.

Thus, the desired equation is y = 3(x+1)^2 - 4 (answer j).

A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable. True or

vesna_86 [32]

The answer is true
Let's imagine that we have the following function function:
 $y = x ^ 2 
$
We have to:
Independent variable: x
Dependent variable: y
For x = -1:
 $y = (- 1) ^ 2 = 1 
$
 For x = 1:
 $y = (1) ^ 2 = 1 
$
 We observe that the independent variable can only obtain one result.

True
