Answer:

The product of a fourth degree polynomial and a third degree polynomial is a 7th degree polynomial (just add the two degrees). Why is this the case? Remember, when you multiply variables with common bases, you add the exponents. Since the degree of a polynomial is just the largest exponent, you're really just adding the degrees when you multiply

Please help with this math homework question below.

<u>Given</u>:

The given equations are $-6 x+4 y=22$ and $y=11-4 x$

We need to determine the pair of numbers that is a member to the system of equations.

<u>Pair of numbers:</u>

The pair of numbers can be determined by solving the system of equations.

Let us use the substitution method to solve the equations.

Substituting $y=11-4 x$ in the equation $-6 x+4 y=22$ , we have;

$-6 x+4 (11-4x)=22$

$-6 x+44-16x=22$

$44-22x=22$

$-22x=-22$

$x=1$

Thus, the value of x is 1.

Substituting x = 1 in the equation $y=11-4 x$ , we get;

$y=11-4(1)$

$y=11-4$

$y=7$

Thus, the value of y is 7.

Hence, the pair of numbers that is a member of both the equations are (1,7)

Explain? How to slove it

Neko [114]

The answer is F because you use the square's measurements as the base of each triangle then multiply each triangle then divide by 2. The multiply by 4 because there are four triangles and multiply 12 by 12 to get 144 because it is the base and the height of the square.

True or False? Tell whether the pair of ratios form a proportion. 4/5 and 5/6 Please explain why you chose what you chose

ivann1987 [24]

Answer:

False. The products from cross multiplication are different.

Step-by-step explanation:

To know if a pair of ratios form a proportion, cross multiply. If the products are equal, they are a proportion.

Write like this to see top (numerator) and bottom (denominator) clearly.

$\frac{4}{5} =\frac{5}{6}$

Multiply each numerator with the other side's denominator:

4 X 6 = 24

5 X 5 = 25

Are they equal? No. 24 ≠ 25

Therefore it's not a proportion.
