Find each union or intersection. Let X = {1, 4, 9}, Y = {x | x is an odd whole number less than 10}, and Z = {2, 4, 6, 8}.
X U Y
X U Z
X n Y
X n Z
Y n Z
Answer:
X ∪ Y = 1, 3, 4, 5, 7, 9,
X ∪ Z = 1, 2, 4, 6, 8, 9
X ∩ Y = 1, 9
X ∩ Z = 4
Y ∩ Z = ∅
Explanation:
X = [1, 4, 9]
Y = [1, 3, 5, 7, 9]
Z = [2, 4, 6, 8,]

Answer:
P1P2 = P1P3 = 2√2P2P3 = 4isosceles right triangle (both)Step-by-step explanation:
The length of a side can be found using the distance formula:
d = √((x2 -x1)^2 +(y2 -y2)^2)
For P1P2, this gives ...
d = √((0-(-2))^2 +(1-(-1))^2) = √(4+4) = √8
P1P2 = 2√2
__
The same ∆x and ∆y apply to P1P3, so we know ...
P1P3 = 2√2
__
The lengths of P1P2 and P1P3 are the same, so the triangle is isosceles.
__
The length of P2P3 can be found by subtracting the y-coordinates:
P2P3 = 1 -(-3)
P2P3 = 4
__
We note that the slope of P1P2 is 2/2 = 1, and the slope of P1P3 is -2/2 = -1. The product of these slopes is (1)(-1) = -1, so we know those lines are perpendicular. The triangle is a right triangle.
Which of the binomials below is a factor of this trinomial?
x² + 14x + 40
O AX-9
O B. 32 + 10
O C. X* 14
D. X+4.
Answer:
D. x + 4Step-by-step explanation:
Let's factor the trinomial:
x² + 14x + 40 = x² + 4x + 10x + 40 = x(x + 4) + 10(x + 4) = (x + 4)(x + 10)x + 4 is between the answer options
Correct option is D.

WILL GIVE BRAINLIEST! What is the equation of the line passing through the points (4, 7) and (7, 13) in slope-intercept form?
Answer:
y = 2x - 1
Step-by-step explanation:
To get slope:
m = y2 - y1 / x2 - x1
m = 13 - 7 / 7 - 4
m = 6 / 3
m = 2
To get y-intercept:
y = mx + b
13 = 2(7) + b
13 = 14 + b
13 - 14 = b
-1 = b
Put it together:
y = 2x - 1

Solve the equation for all values of x in simplest form (x + 3)^2 = -16
Answer:
x = -7 or x = 1
Step-by-step explanation:
Given expression:
(x + 3)² = -16
Problem;
Solve for x;
Solution:
To solve for x; we use the factorization method;
Take -16 to the left of the equation;
(x + 3)² = -16
(x + 3)² + 16 = 0
(x+ 3)² + 4² = 0
if x² + y² = (x + y)(x - y)
So;
(x + 3 + 4) (x + 3 - 4) = 0
(x + 7)(x - 1) = 0
x + 7 = 0 or x - 1 = 0
x = -7 or x = 1
