Find the length of GH!

Mathematics
2 answers:
Sati [7]3 years ago

Answer:

A

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = G(6, 5) and (x₂, y₂ ) = H(8, 9)

GH = \sqrt{(8-6)^2+(9-5)^2}

      = \sqrt{2^2+4^2}

      = \sqrt{4+16}

      = \sqrt{20} ≈ 4.5 → A

Distance formula is square root of (x2-x1)^2 plus (y2-y1)^2
Which is the square root (6-8)^2 plus (5-9)^2
Which is 4.47
Which is approximately 4.5 hope this helps ;)

How do I Simplify 4a – 7b + 2ab – a + b (I need step by step cause I'm trying to learn this)
Alex

Step-by-step explanation:

Ok. First of all, we need to follow the order of operations: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. We don't have any parentheses, exponents, or division to resolve, so you can skip those. So now you have: Multiplication, Addition, and Subtraction. We have multiplication in each term, but each term is fully simplified, so we have Addition and Subtraction left.

With that out of the way, let's go ahead and rearrange this equation so it is easier to solve. (<em>Note: we can only rearrange terms that are positive because subtraction is not commutative. But we can turn negative terms into "positive" terms by the method shown below.</em>)

4a - 7b + 2ab - a + b

4a + (-7b) + 2ab + (-a) + b (<em>Now the terms are all positive, so we can rearrange them, but they still have the same value.</em>)

4a + (-a) + 2ab + (-7b) + b

3a + 2ab + 7b

And there we go. Our answer is fully simplified. If you can understand this, you'll be able to simplify without isolating and rearranging the terms each time.

Hopefully this was helpful and not confusing.

What is the equation of a line passing through (-3,7) and having a slope of -1/5<br> PLEASE HELP
OLEGan [10]

Answer:

y = -1/5x +32/5

Step-by-step explanation:

The slope intercept form of the equation of a line is

y = mx+b

we know m = -1/5

y = -1/5x+b

We know a x and y on the line

7 = -1/5(-3) +b

7 = 3/5 +b

Subtract 3/5 from each side

35/5 -3/5 = b

32/5 =b

So the equation is

y = -1/5x +32/5
