Answer:

X = 9

Step-by-step explanation:

4 + 3 + 4 + 6 + 1 + x / 6 = 4.5

18 + x / 6 = 4.5

cross multiply

18 + x = 4.5 × 6

18 + x = 27

collect like terms

x = 27 - 18

x = 9

Which function is equivalent to F(x)=-4(x+7)^2-6?
Gemiola [76]

\huge\mathfrak\orange{answer}

Simplify this quadratic function given in vertex form into standard form by simplifying the exponents and adding like terms.

f(x) = \red{-4(x+7)^2 - 6}

f(x) = -4(x^2 + 14x + 49) - 6

f(x) = -4x² - 64x - 196 - 6

\underline{f(x) = -4x² - 64x - 202}

(good luck :) and mark me brainliest if you're satisfied with my answer)

In triangle NQL, point S is the centroid, NS = (x + 10) feet, and SR = (x + 3) feet.
olya-2409 [2.1K]
Where R is the median between Q and L:

From my understanding of a triangle's centroid, it divides an angle bisector into parts of 2/3 and 1/3. In the given problem, these divisions are NS and SR. Therefore, twice SR would be equal to NS. From here, we can get the value of X, to solve for SR.

NS = 2SR
(x + 10) = 2(x + 3)
x + 10 = 2x + 6
x = 4

Therefore, SR = (x + 3) = 7

How do you get the average of something
kogti [31]
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
