Mathematics

3 0

Answer:

x =  -  \frac{2}{3}  \:  \:  \: y =  \frac{14}{3}

Step-by-step explanation:

Since we know -7x=y we use the substitution method and plug it in the top equation.

x + - 7x = 4

- 6x = 4

x =  -  \frac{4}{6}

or x=-2/3

Then plug it back in the the bottom equation

- 7( \frac { - 2}{3} ) = y

y=14/3

What is the highest common factor of 27 and 36?
snow_lady [41]
Hello there!

The highest common factor, also known as the greatest common factor, or GCF, is the biggest factor that both numbers have in common.

Let's factor out our numbers.

27;
1 x 27
3 x 9

36;
1 x 36
3 x 12
4 x 9
6 x 6

Both of these numbers have these in common:
1, 3, 9.

Since 9 is the highest number in common, it is our GCF or highest common factor.

I hope this helps!

Rearrange the formula to make a the subject
PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

p = (3n + a)/(n + a)

Cross multiply

p(n + a) = 3n +a

pn + pa = 3n + a

pa - a = 3n - pn

a(p - 1) = n(3 - p)

Dividing by p - 1

a = n(3 - p)/(p - 1)

PLEASE PLEASE PLEASE HELP!!!!! 95 points!!!
zysi [14]

The "rule" being described here is nothing more than the input/output of a mathematical function.


For every input 'x' value supplied, you only need to subtract three to it. For every input 'y' value, you only need to add four to it.


Example: I'll use variable 'm' to represent this function. Variable 'p' will represent the current input point.


m(p) = p[x - 3, y + 4] = p[-7 - 3, 0 + 4] = p[-10, 4]. 'p[]" is just the point.

I tried my best hope that help!
