Answer 1

Answer:

1) 1

2) (2,3)

3) x⁴

Step-by-step explanation:

1)

We have the expression:

$7x+1$

The degree of an equation is the largest exponent of the equation.

We can rewrite our expression as:

$=7x^1+1x^0$

1 is the largest exponent.

Thus, our degree is 1.

2)

We have the system of equations:

$x+y=5\\3x-y=3$

To solve, we can use substitution.

From the first equation, subtract x from both sides:

$y=5-x$

Substitute this into the second equation:

$3x-(5-x)=3$

Simplify:

$3x-5+x=3$

Add 5 to both sides:

$3x+x=8$

Combine like terms:

$4x=8$

Divide both sides by 4:

$x=2$

So, x is 2.

Substitute this back into the first equation:

$x+y=5$

Substitute x for 2:

$2+y=5$

Subtract 2 from both sides:

$y=3$

Our solution is (2,3)

3)

We have the expression:

$\frac{x^4}{x^0}$

Anything to the zeroth power (except for 0) is 1. Assuming x is not 0:

$=x^4/1\\=x^4$

And that's the simplest it can get.

Answer 2

Answer:

$\Huge \boxed{\mathrm{1. \ 1}} \\ \\ \\ \Huge \boxed{\mathrm{2. \ (2,3)}} \\\\\\ \Huge \boxed{{3. \ x^4 }}$

Step-by-step explanation:

The degree is the largest exponent on the variable.

$7x^1 + 1x^0$

The largest exponent on the variable is 1.

The degree is 1.

System of equations:

$x+y=5 \\ \\ 3x-y=3$

Solving y for the first equation.

Subtracting x from both sides.

$y=5-x$

Substitution method.

$3x-(5-x)=3$

Distribute negative sign.

$3x-5+x=3$

Combining like terms.

$4x-5=3$

Adding 5 to both sides.

$4x=8$

Dividing both sides by 4.

$x=2$

Substitution method.

$y=5-2 \\ \\ \\ y=3$

$\displaystyle \frac{x^4 }{x^0 }$

Subtract exponents with same bases when dividing.

$x^{4-0}$

$x^4$
