NEED SOME HELP HERE!!

Mathematics
1 answer:
Stolb23 [73]3 years ago
5 0

Answer:

6 and 8

Step-by-step explanation:

Pythagorean theorem: a² + b² = c²

Given this,

(3x)² + (4x)² = 10²

9x² + 16x² = 100

25x² = 100

Divide both sides by 25

x² = 4

x = 2

Substitute this into 3x and 4x.

3x = 3 * 2 = 6

4x = 4 * 2 = 8

Thus, the answer is 6 and 8

A segment has one endpoint at (-4,1) and it's midpoint at (3,0). What is the x-coordinate of the other endpoint?
nikklg [1K]

Answer:

(10; -1)

the x-coordinate of the other endpoint is (x;y)

because the segment has midpoint at (3;0)

=> x - 4 = 3.2 = 6

y + 1 = 0.2 = 0

<=> x = 10

y = -1

=> the other endpoint is (10; -1)

WHAT DOES THIS MEAN I DONT UNDERSTAND
Art [367]

Answer:

the goal is to try and get x alone. For the 1st problem, x=3.

Step-by-step explanation:

3x + 1 = 10      Subtract 1 both sides to cancel out the 1 on the left side. 10-1 = 9

3x = 9             To get x alone here, Divide 3 on both sides. 9/3 = 3

x = 3                Now x is alone, which means x = 3.

This is right because if you plug x with 3, the sum = 10.

(3*3) + 1 =10

9 + 1 = 10

So, that's how you know 3 is the right answer.
