Answer: YES

Step-by-step explanation:

8p - 2q = 14

8(1) - 2(-3) = 14

8 - -6 = 14

8 + 6 = 14

14 = 14

TRUE

(p, q) = (1, -3)

Plug in the corresponding numbers to the corresponding variable

8p - 2q = 14

8(1) - 2 (-3) = 14

Simplify. Remember to follow PEMDAS. First, multiply

8 x 1 = 8

-2 x -3 = 6

8 + 6 = 14

Finally, add

(8 + 6) = 14

14 = 14 (True)

Yes, (1, -3) is a solution for 8p - 2q = 14

Find the degree of the monomial. -1.75k2

HACTEHA [7]

Answer:

The degree of this monomial is 2.

Step-by-step explanation:

This is because the degree of a monomial (or a polynomial, binomial) is equal to the degree (exponent) of the term in the monomial. In polynomials, it would be the degree of the term with the HIGHEST degree.

-1.75k^2

The exponent is two, so the degree is two.

Hope this helped!!!

The drama club was selecting which carnival booths to sponsor at the fall carnival from a list of nine. How many different ways

denis-greek [22]

Answer:

Option B

Step-by-step explanation:

Here we have to apply " combination and permutation. " It is given that the drama club had to choose three booths from a selection of 9, considering the possible ways to choose so. This is a perfect example of combination. In nCr, n corresponds to 9, respectively r corresponds to 3.

$\mathrm{n\:choose\:r},\\nCr=\frac{n!}{r!\left(n-r\right)!},\\\\\frac{9!}{3!\left(9-3\right)!} =\\\frac{9!}{3!\cdot \:6!} =\\\\\frac{9\cdot \:8\cdot \:7}{3!} =\\\frac{504}{6} =\\\\84\\\\Solution = Option B$

Hope that helps!
