Answer:

answer is no, not a right triangle

Step-by-step explanation:

if it is a right triangle then the sum of the square of the two smaller legs will equal the square of the longest leg

does 8² + 12² equal 15²?

64 + 144 = 225

208 ≠ 225

answer is no, not a right triangle

Image point B (4,-8) was transformed using the translation (x-2,y+3) what were the coordinates of B?
PilotLPTM [1.2K]
The coordinates of the image point are given to be B(4, -8). We are to find the coordinates of pre-image that is the coordinates before the translation.

The translation made was (x-2, y+3) 

This means, the x coordinate was moved 2 units to left and y coordinate was moved 3 units above. 

So, the coordinates of original point will be, 2 units to right of B and 3 units down of B.

So the coordinates will be (6, -11)

If f(x) = 3x + 2, what is f(5)?
iVinArrow [24]

Hi there!

\large\boxed{f(5) = 17}}

f(x) = 3x + 2, find f(5):

To find f(5), we simply substitute in 5 for x:

f(5) = 3(5) + 2

f(5) = 15 + 2

f(5) = 17

Triangle ABC has side lengths 10, 14, and 26. Do the side lengths form a Pythagorean triple? Explain.
uysha [10]
By <span>Pythagorean triple
a²+b²=c²,
c should be longest side
10²+14²=26²
100+196=676
296</span>≠676
so sides do not form  Pythagorean triple, it is not a right triangle
