What is value of x and y if Y=-2x+8 and Y=3x-7

Mathematics
1 answer:
iren [92.7K]3 years ago
3 0

Answer:

X=5 y=-2

Step-by-step explanation:

Set them equal to each other so...

-2x+8=3x-7

Simplify by balancing out the equation so

-5x=-1

So x=5

Now plug it into either y equation

-2(5)+8

-10+8

Y=-2

Hope this helps!

What expression shows the relationship between the value of any term and n, its position in the sequence for the given sequence?
mafiozo [28]
Answer: -3n-2. 

Because for the first term, for example, plug in 1, you'll get -3(1)-2=-3-2=-5, which is the first one. Try it with all terms.

Is the set of integers closed under division? Explain why or why not.
MrMuchimi

The set of integers is not closed under the operation of division because when an integer is divided by another, the results are not limited to only integers i.e. zero and decimals are possibilities

<h3>How to determine the true statement?</h3>

Integers are numbers without decimal points

When integers are divided, the possible results are:

  • Zero
  • Decimal
  • Integers

The decimal and the zero possibilities imply that the set of integers is not closed under the operation of division

This is so because when an integer is divided by another, the results are not limited to only integers i.e. zero and decimals are possibilities

Given that g(x) = x^5 - 5x^4 + 10x^3 - 10x^2 + 5x - 1, find g^-1(x).
Ivan
First Factor.

(x-1)^5 = x^5 -5x^4+10x^3 -10x^2+5x-1

g(x) = y = (x-1)^5

Find inverse by solving for 'x'

x-1 = y^{1/5} \\  \\ x = y^{1/5} +1 \\  \\ g^{-1} (x) = x^{1/5} + 1
