Answer:

(1, 1), (2, 4), (3, 9), (4, 16)

Step-by-step explanation:

You recognize that, of the numbers in Y, 20 is not a square. You also recognize that the remaining values of Y correspond to the squares of the values of X:

(x, x^2) = {(1, 1), (2, 4), (3, 9), (4, 16)}

Triangle STV has vertices S (-3, -2) , T (-4, 3) and V (-2, 3). If (x, y) arrow (x+2, y-3), what are the vertices of its image?

jeka94

Answer:

see below

Step-by-step explanation:

The mapping tells you how to find the vertices of the image:

(x, y) ⇒ (x +2, y -3)

S(-3,-2) ⇒ S'(-3 +2, -2 -3) = S'(-1, -5) . . . . . matches choice D

T(-4, 3) ⇒ T'(-4 +2, 3 -3) = T'(-2, 0)

V(-2, 3) ⇒ V'(-2 +2, 3 -3) = V'(0, 0)

Answer:

5√2

Step-by-step explanation:

Finding distance :-

d = √{ ( 1 -6)² + (4+1)²}
d = √{ -5² + 5² }
d = √{ 25 + 25}
d = √50
d = 5√2

Answer:

Equation: x + (x+ 1) = 67

Step-by-step explanation:

We want to find two consecutive integers.

Let them be labeled as x and x + 1

We want x + (x + 1) = 67

x is the smaller number

x + 1 is the largest

We can solve for x.

x + (x + 1) = 2x + 1 = 67

2x = 66

x = 33

The largest integer is 34
