Answer:

A. Commutative Property of Addition

Step-by-step explanation:

Given equation,

9 + 8 = 8 + 9

If a and b are any real numbers,

By the commutative Property of Addition

a + b = b + a

By the identity Property of Addition

a + 0 = a

By the distributive Property,

a(b+c) = ab + ac

By the associative property of addition,

a + (b + c ) = (a + b) + c

Hence, OPTION A is correct.

Answer:

Commutative Property of Addition

Step-by-step explanation:

I assume you mean 9+8=8+9

In that case it is the Commutative Property of Addition.

That means you can switch the numbers around and it will stay the same value.

when x increases by 2 units, then also y increases by more or less 2 units.

when x increases by 3 units, then also y increases by more or less 3 units.

it is not precise, but a good approximation model.

ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions
77julia77 [94]

Answer:

C. It has been stretched horizontally.

Step-by-step explanation:

According to the diagram, the parabola has not been reflected in any way, nor has it been translated, since the parabola is pointing up in a smile, and the vertex is still at the origin.

The parabola does appear to be stretched, since the parent function had points at (1, 1), and (2, 4), but this parabola does not contain those points.

Since the parabola appears to be flatter than the parent function, we can say that C. It has been stretched horizontally.

Hope this helps!
