Answer:

addition property of equality

Step-by-step explanation:

The equation y – 9 + 9 = –17 + 9 is an example of which property

A.Substitution Property of Equality:

In this property we substitute some particular value for the variable.

B.Addition Property of Equality

This property states that when we add any number to one sides of the equation we do the same on the other side

y – 9 + 9 = –17 + 9

In the equation , 9 is added on both sides of the equation. So it is an example of addition property of equality

C.Reflexive Property of Equality

Reflexive property states that the number is equal to itself

D. Symmetric Property of Equality

It states that if a=b then b=a

You add 9 to both sides to get:
y – 9 + 9 = –17 + 9

so it's Addition Property of Equality

Answer:

Step-by-step explanation:

First, find the ratio between the triangles. To do this, divide any side of the big triangle by corresponding side in the small triangle. I chose 35. So, 35/10 = 3.5. 3.5 is the ratio between the triangles. Multiply 3.5 by 8 to get 28, the length of the missing side. :)

For which interval is the function increasing Choose two answers that are correct

kaheart [24]

Answer:

-8 ≤ x ≤ - 6

2 ≤ x ≤ 6

Step-by-step explanation:

Increasing part of the function can be easily determined from the graph.

Note that increasing function means for each successive values of 'x', the values of 'y' keep increasing.

From the graph, we see that the function is increasing in the interval $- 8 \leq \ x \leq -6$

Between -6 and -4, the graph is constant and takes the value 4.

After that it decreases till x = -2 until it becomes a constant function again on x = 2.

Then, it again increases from x = 2 till x = 6. This is represented by the interval

$2 \leq x \leq 6$ .

Then it again decreases.

So, OPTION A and C are the answers.
