Let's start working with equation A:

y = 3x - 2

Slope intercept form:

y = 3x - 2

Slope

m = 3

Equation B:

3x + y = 5

Slope intercept form:

y = -3x + 5

Slope

m = -3

Now, let's graph the slope intercept form of both equations, as follows:

As we can confirm, A and B, are neither parallel nor perpendicular

3 times the sum of a number n and 12 is 45
Jet001 [13]
In order to solve this question we first have to break down the terms.

Sum = Adding
Times = Multiplying.

The question states "3 times the sum of a number n and 12 is 45". In written form, it would be the following:

3(12+n) = 45

To solve this you first divide both sides by three and you'd be left with the following:

(12+n) = 15.

Then subtract 12 from both sides. Leaving you with:

n = 3

Find the values of the variables
Jlenok [28]

Answer:

You can use Pythagoras theorem to calculate x:

12² + 14² = x²

144 + 196 = x²

           x² = 340

           x   = √340 ≈ 18,44

Adam had 91dollars. If he spent 21 dollars on new books, what is the ratio of the money he still has to money he's spent.
tankabanditka [31]

Answer:

3/13

Step-by-step explanation:

ratio is another way to say fraction, so we have 21/91.  This can be reduced if we divide by 7: 21/7 = 3, 91/7 = 13.  Now we have 3/13.  You can write it as 3:13 or 3/13.
