1) The given expression 7x^4 + 5x^2 + x - 9 is a polynomial.

2) The given expression 7x^6 - 4x^3 + 1/x is a trinomial.

<u>Step-by-step explanation</u>:

1) 7x^4 + 5x^2 + x - 9

The number of terms in the above expression is 4.
An algebraic expression with more than 3 terms is known as polynomial.
<u>The degree is the power of the x term in a expression</u>
first term = 7x^4 has a degree of 4.
second term = 5x^2 has a degree of 2.
third term = x has a degree of 1.
fourth term = 9 is a constant term with no degree.

2) 7x^6 - 4x - 1/x

The number of terms in the above expression is 3.
An algebraic expression with 3 terms is known as trinomial.
first term = 7x^6 has a degree of 6.
second term = 4x has a degree of 1.
third term = 1/x has a degree of -1.

Answer:

$u^{6}$

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$ , then

u³ × u³ = $u^{(3+3)}$ = $u^{6}$

Which BEST describes the system of equations? y = 4x + 3 y = 2x − 4 A) Consistent B) Inconsistent C) Consistent and Dependent D)

cestrela7 [59]

Answer:

D) Consistent and Independent

Step-by-step explanation:

The system of equations,

$a_{1} x+b_{1} y+c_{1} =0$ and

$a_{2} x+b_{2} y+c_{2} =0$

is consistent and independent if $\frac{a_{1} }{a_{2}} \neq \frac{b_{1} }{b_{2}}$

The system is consistent and dependent if $\frac{a_{1} }{a_{2}} =\frac{b_{1} }{b_{2}} =\frac{c_{1} }{c_{2}}$

The system is inconsistent if $\frac{a_{1} }{a_{2}} =\frac{b_{1} }{b_{2}} \neq \frac{c_{1} }{c_{2}}$

Now, in the given system

4x - y + 3 = 0 and

2x - y - 4 = 0

$\frac{a_{1} }{a_{2}} =\frac{4}{2} =2$

$\frac{b_{1} }{b_{2}} =\frac{-1}{-1} =1$

So, $\frac{a_{1} }{a_{2}}\neq \frac{b_{1} }{b_{2}}$

Hence, the given system is consistent and independent.

Using the distributive property what is 2(-5+3) as an equivalent expression

photoshop1234 [79]

Answer:

-4

Step-by-step explanation:

Because when distrubuting first you distribute 2(-5) which gives you -10 and then you distribute 2 into 3 which is 2(3) which gives you 6. So now you have -10+6. So you can further simplify that into -4. We get -4 because -10 + 6 is -4. And the 4 is negitive because there are more negitives than positives.
