Answer:
(x-2,y-4), (x-2,y-3) and (x-4,-y3)
Step-by-step explanation:
The rule is (x,y)-->(-x,-y) so
(x2,y4)=(x-2,y-4)
(x2,y3)=(x-2,y-3)

Determine if each set of numbers can be the lengths of the sides of a right triangle:
Answers
Solution:
The side lengths can only be classified as a right triangle if it is a Pythagorean triple. To classify the side lengths as a Pythagorean triple, it must satisfy "c² = b² + a²".
Where:
c = Longest side (Hypotenuse)b = Lega = LegChecking (5, 12, 13):
c² = b² + a²13² = 12² + 5²169 = 144 + 25169 - 144 = 2525 = 25 (Yes)Checking (12, 35, 20√3):
(20√3)² = 35² + 12²(20√3)(20√3) = 1225 + 1441200 = 1225 + 144 (No)Checking (5, 10, 5√5):
(5√5)² = 10² + 5²125 = 100 + 25125 = 125 (Yes)Checking (8, 12, 15):
15² = 12² + 8²225 = 144 + 64 (No)Checking (20, 99, 101):

Find the volume of the triangular prism shown below:
Answers
Answer:
18 cm³
Step-by-step explanation:
To find the volume of a triangular prism, find the area of the cross-section (in this case, the triangle) and multiply it by the length.
The area of the triangle is 1/2 × 4 × 3 = 6 cm²
Now, multiply 6 by 3 to get 18 cm³

How you solve this by using solving proportions
Answers
3/(x + 4) = (x + 2)/5
Multiply both sides by 5 :
5 × 3/(x + 4) = 5 × (x + 2)/5
15/(x + 4) = x + 2
Multiply both sides by x + 4 :
(x + 4) × 15/(x + 4) = (x + 4) × (x + 2)
Provided that x + 4 ≠ 0, we can cancel the factors of x + 4 on the left side:
15 = (x + 4) (x + 2)
Expand the product on the right side:
15 = x² + 6x + 8
Move everything to one side:
0 = x² + 6x - 7
We can factorize easily in this case
0 = (x + 7) (x - 1)
Then
x + 7 = 0 or x - 1 = 0
⇒ x = -7 or x = 1

A line passes through the points (3,16) and (6,19). Write a linear function rule in terms of x and y for this line.
Answers
Answer:
y=1x+13
Step-by-step explanation:
First find the slope of the line. Slope is (y2-y1)/(x2-x1). Plug in 19 for y2, 16 for y1, 6 for x2, 3 for x1. So (19-16)/(6-3) is 3/3 or 1. The slope of the line is 1.
take the equation y=mx+b and plug 1 in for the slope (m). Then plug in one set of points. Using (3,16) into y=1x+b, 16=1(3) + b. Solve for b. B is 13. So the linear equation is y=1x+13.

I need help with 2(4/3)x8x15+280919 we couldn’t use calculator
Answers
Answer:
281,319.005
Step-by-step explanation:
Because 2 and 4/3=3 and 1/3
Because since the numerator= 4 and the denomeyer is 3 we can add another whole number so 2 and 4/3 can add whole so 2 + 1=3 wholes with 1 left over so 3 1/3.
Next we do 3 1/3 x 8 which=26.667 also known as 26 2/3
Because 2/3=66.667.
Next we so 26 and 2/3 x 15=400.005
And last 400.005 + 280,919=281,319.005
