What is 8q+12=4(3+3q)
Elena-2011 [213]

Answer:

q = 0

Step-by-step explanation:

8q + 12 = 4( 3 + 3q )

Distributive property

8q + 12 = 4 ( 3 + 3q )

8q + 12 = 12 + 12q

Inverse operations

8q + 12 = 12 + 12q

-8q               -8q

12 = 12 + 4q

-12  -12

0 = q

q = 0

In 2017, solar and wind electricity generation totaled 218 thousand megawatt hours (MWH) Wind generated 2 thousand MWH more than
Lyrx [107]

Answer:

W=191,000MWH S=27,000MWH

Step-by-step explanation:

OK, let's W be wind electricity generated and S, solar electricity generate.

TOTAL GENERATED: <u>218,000mwh = W + S </u>

RELATION BETWEEN W AND S: <u>W = 2,000mwh + 7S</u>

We have now two equations:

218,000 = W + S

W = 2,000 + 7S

Put th value of W into the 1st equation in order to find S:

218,000 = 2,000 + 7S + S

218,000 = 2,000 + 8S

218,000 - 2,000 = 8S

216,000 = 8S

S = 216,000/8

S = 27,000mwh

Now, we find W.

W = 2,000 + 7*27,000mwh

W = 2,000 + 189,000mwh

W = 191,000mwh

Is the function f(x)^2-3x^4+3/4 x-7 a polynomial function? If so, please state its degree and the leading coefficient.
Svet_ta [14]
Yes, it is a polynomial function, because it is a function consisting of several terms that can't be added together without knowing x. 

It is a 4th degree polynomial, since it's highest degree term, the term with the highest exponent, (3x⁴), which has a degree of 4.
