First find slope
(2-4)/(3+1) = -2/4 = -1/2
Use point (3,2)
y-y1 = m(x-x1)
Plug everything in
y-2 = -1/2(x-3)

Solution: A

Answer:

The Answer is A, or y-2=-1/2(x-3)

Step-by-step explanation:

First you multiply -1/2 by the (x-3) and that gives you -1/2x +1.5.

Then you can move the -2 over which then makes it positive, you add that to the 1.5 and your y intercept is 3.5.

Your slope ends up being -1/2

Y-intercept ends up being 3.5

Hope I helped:)

Write each of the numbers 1, 4, 9, 16, and 25 as a base raised to the second power. Explain why these numbers are sometimes call
vodka [1.7K]
First, we can raise each number to the second power by multipying it by itself. :)
1^2=1
4^2=16
9^2=81
16^2=256

These numbers are called "perfect squares" because their square roots are whole numbers, rather than decimals. For example, If you had a square with an area of 16, the side legnths of the square would be the whole (thus "perfect") number 4. For this reason, 16 (4^2) is considered a "perfect square" number. I hope that makes sense!! :)

  • Left to Right

<u>Geometry</u>

  • [Right Triangles Only] tan∅ = opposite over adjacent

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use trig to find the missing side length.

<u>Step 2: Identify Variables</u>

<em>POV from the angle measure</em>

Angle = 23°

Opposite Leg = 25

Adjacent Leg = <em>x</em>

<em />

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Substitution [tangent]:                    tan23° = 25/x
  2. Multiply <em>x</em> on both sides:                xtan23° = 25
  3. Isolate <em>x</em>:                                          x = 25/tan23°
  4. Evaluate:                                          x = 58.8963
  5. Round:                                             x ≈ 58.9

What does AC=?<br> Round your answer to the nearest hundredth. <br><br> Please help
faltersainse [42]

Answer: About 3.06

Step-by-step explanation:

  We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

  Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

      cos(θ) = \frac{adjacent}{hypotenuse }

      cos(40) = \frac{x}{4}

      0.766 ≈ \frac{x}{4}

      3.06 ≈ x

      x ≈ 3.06

Again again please help
ANEK [815]

Answer:

x = 1

Step-by-step explanation:

2x−2+6x=6

Combine 2x and 6x to get 8x.

8x−2=6

Add 2 to both sides.

8x=6+2

Add 6 and 2 to get 8.

8x=8

Divide both sides by 8.

x = \frac{8}{8}

Divide 8 by 8 to get 1.

x=1

Hope it helps and have a great day! =D
