Answer:
A) AA similarity
Step-by-step explanation:
AA stands for "angle, angle" and means that the triangles have <u>two</u> of their angles equal.
SAS stands for "side, angle, side" and means that we have two triangles where the ratio between two sides is the same as the ratio between another two sides and we we also know the included angles are equal.
SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio.
Here we can easily see that two angles are equal
- ∠CYK and ∠KZP
- ∠CKY and ∠PKZ (they're cross angles)
Therefore it's AA similarity
Answer:
Step-by-step explanation:
11) 3(x-5) + 2(x -1)
distributive multiplication: 3x - 15 + 2x - 2
group like terms : 3x + 2x - 15 - 2
Simplify: 5x - 17
12) arrow is from -3 going towards the right side, meaning greater value. since the circle above -3 is hollow it means that it is not included or not equal.
x > -3
13) 3x + 2y : x = -3 ; y = -4
substitute x and y by its values : 3(-3) + 2(-4) ⇒ -9 - 8 = -17
14) f(n) = -1 + 3(n-1) :
-1 is the first term ; 3 is the common difference ; n is the term you are searching for.
example: n = 4
f(4) = -1 + 3 (4-1) ⇒ f(4) = -1 + 3(3) ⇒ f(4) = -1 + 9 ⇒ f(4) = 8
8 is the fourth term in the sequence.
15) y = 3x² + 4 ; x = -2
y = 3(-2²) + 4
y = 3(4) + 4
y = 12 + 4
y = 16
