A line has a slope of 2. It passes through the points (1, 2) and (3, y) . What is the value of y? y=
malfutka [58]

Answer:

6

Step-by-step explanation:

To solve this , we use the equation of finding a slope wig a line.

m = (y2 - y1)/(x2 - x1)

From the question, we know that:

y2 = y

x2 = 3

y1 = 2

x1 = 1

m = 2

Hence,

2= (y - 2)/(3 - 1)

2 = (y - 2)/2

4 = y - 2

y = 2 + 4 = 6

10 + 6x + 2x - 7 = 35<br> Help me pls and ty
lutik1710 [3]

Answer:

<h2><em><u>x = 4</u></em></h2>

Explanation:

10 + 6x + 2x - 7 = 35

  • Add Similar Elements: 6x + 2x = 8x

10 + 8x - 7 = 35

  • Group Like Terms

8x + 10 - 7 = 35

  • Subtract: 10 - 7 = 3

8x + 3 = 35

  • Subtract 3 From Both Sides

8x + 3 - 3 = 35 - 3

  • Simplify

8x = 32

  • Divide Both Sides By 8

8x / 8 = 32 / 8

<h2><u><em>x = 4</em></u></h2>

Use the Pythagorean theorem to determine which of the following give the measures of the legs and hypotenuse of a right triangle
Masteriza [31]

Answer: 3, 4,5 and 17, 15,8

give the measures of the legs and hypotenuse of a right triangle.

Step-by-step explanation:

In order for the measures of the legs and hypotenuse given to form a right angle triangle, they must be Pythagorean triples. A Pythagoras triple is a set of numbers that perfectly satisfy the Pythagorean theorem. The Pythagorean theorem is expressed as

Hypotenuse² = opposite side² + adjacent side². We will apply the theorem to each set of numbers given.

1) 3, 4, 5

5² = 3² + 4² = 9 + 16

25 = 25

It is a Pythagorean triple

2) 4, 11, 14

14² = 11² + 4² = 121 + 16

196 = 137

It is a Pythagorean triple

3) 9, 14, 17

17² = 14² + 9² = 196 + 81

289 = 277

It is not a Pythagorean triple

4) 8, 14, 16

16² = 14² + 8² = 196 + 64

256 = 260

It is not a Pythagorean triple

5) 8, 15 , 17

17² = 15² + 8²

289 = 225 + 64

289 = 289

It is a Pythagorean triple

Therefore, 3, 4,5 and 17, 15,8

give the measures of the legs and hypotenuse of a right triangle.
