Answer:

349

Step-by-step explanation:

We know that a₁ (the first term) is 6 and d (the common difference) is 13 - 6 = 7.

Explicit formula: aₙ = a₁ + (n - 1)d = 13 + (n - 1) * 7 = 7n - 1

Therefore, a₅₀ = 7(50) - 1 = 349

Answer:

-2/5

Step-by-step explanation:

Slope is rise over run according to my former algebra teacher, but I learned it differently (still correct tho).

The first moves 2 units down so negative 2, and moves 5 units right, so -2/5 since the rise is -2, and run is 5.

The second one moves 2 x-units for every 1 y-unit, so the slope is 2,

mamaluj [8]

Answer: x²+8x+16

Step-by-step explanation:

(x+4)^2=(x+4)(x+4)

Now use distributive property to expand (x+4)(x+4):

(x+4)(x+4)=x²+4x+4x+4(4)

x²+4x+4x+4(4)=x²+8x+16

The population of Virginia is 24% less than the population of Georgia,. If the population of Georgia is 10.5 million what is the

zlopas [31]

The population of Virginia is 7,980,000 people.

Let the population of Virginia be V.

Let the population of Georgia be G.

<u>Given the following data:</u>

Population of Georgia = 10.5 million

To find the population of Virginia:

Translating the word problem into an algebraic expression, we have;

24% percent less:

$\frac{24}{100}$ × $10500000$

$24$ × $105000$

24% of G = 2,520,000

Now, we can find the population of Virginia:

$V = G - 2,520,000$

$V = 10,500,000 - 2,520,000$

<em>V = 7,980,000 people.</em>

Therefore, the population of Virginia is 7,980,000 people.
