Which points of the following points are solutions to the equation 3x-4y-8=12

Natali [406]

Answer:

(0, -5), (4, -2), (-16, -17)

Step-by-step explanation:

I attach your full question in the image below

The equation is

3x-4y-8=12

Which can be rewritten as

3x-4y =12 +8

3x-20 = 4y

y = (3/4)*x - 5

We need to check each individual case

(0,-5)

y = (3/4)*(0) - 5

y = -5

True

(4,-2)

y = (3/4)*(4) - 5

y = -2

True

(8,2)

y = (3/4)*(8) - 5

y = 1

False

(-16,-17)

y = (3/4)*(-16) - 5

y = -17

True

(-1,-8)

y = (3/4)*(-1) - 5

y = -23/4

False

(-40,-34)

y = (3/4)*(-40) - 5

y = -35

False

(0,-5) (4,-2) and (-16,-17) are the solutions

Answer:

c = 5√5

Step-by-step explanation:

When we have a right triangle, there is a property about its measurements that is always true, and its called the "Pythagorean Theorem"

First, let's understand the basic terms we use to describe the sides of a triangle:

we can call one leg "a", the other leg "b" and the slanted side "c"

("c" is also called the hypotenuse--and it's always opposite the 90-degree angle)

the pythagorean theorem:

a² + b² = c²

here, our "a" is 5, our "b" is 10 {and we don't know what c is}

let's try plugging these values into our formula:

a² + b² = c²

5² + 10² = c²

25 + 100 = c²

125 = c²

now, we know what c² is--but we want to know c,

so we must take the square root of both sides

√125 = √c²

√125 = c

now, while √125 is our answer, we can simplify further!

this is because 125 can be made up of 5 · 25

so, $\sqrt{125} = \sqrt{5*25}$

and

$\sqrt{5*25}=\sqrt{5}*\sqrt{25}$

we can take out the square root of 25 (5):

$=\sqrt{5}*5$

we write this as such: $5\sqrt{5}$

so, in simplest radical form, c = 5√5

(√125)

hope this helps!! have a lovely day :)

What is the missing step in this proof?

garri49 [273]

I'm not really sure what I'm looking at... is it possible for you to take a better picture so I can look at the diagram if there is one + the rest of the steps?
