Answer:

a=2

Step-by-step explanation:

8a +9=3a +19

Subtract 9 from both sides

-9=      -9

8a=3a +10

Subtract -3a from both sides

5a=10

5a=10

5a divided by both sides

5/5

10/5=2

a=2

Why do test makers refer to the first term in a sequence as a sub zero sometimes as opposed to a sub 1?
Kaylis [27]

The first term in a sequence is sometimes referred to as a_0 as opposed to a_1 because a_0 represents the initial value

<h3>How to explain the sequence statement?</h3>

The question refers to the difference between the terms

a_o and a_1

The terms in a sequence are represented by a subscript number.

Take for instance a₂ or T₂ represents the second term.

However, when the first term is represented by a₀ instead of a₁.

It means that the sequence has an initial value, other than the first term.

Even though the words "first" and "initial" are synonyms, they do not entirely represent the same thing.

Take for instance, a₀ can be used instead of a₁ in the following scenario

<em>The population of a country is 1000 in 1996 and The country experiences an increment of 250 people every year after 1996.</em>

<em />

The above means that:

a₀ = 1000 --- the initial year

a₁ = 1000 + 250 = 1250 ---- the first year after 1996 (i.e. 1997)

100 POINTS IF YOU ANSWER CORRECTLY Rotate these coordinates 180 around the origin and then translate 6 units to the left.
snow_tiger [21]
Original Coordinates: (-2, -8) (-6, -8) (-11, -1) (-7, -3)

A 180 degree rotation around the origin flips the signs of x and y, so you get:

(2, 8) (6, 8) (11, 1) (7, 3)

Then a translation to the left 6 units just subtracts 6 from all the x values:

(-4, 8) (0, 8) (5, 1) (1, 3)

Those are your points! Hope this helped!
