Find the term of the arithmetic sequence in which a 27=-1/2 and the common difference is 2.

Answers

Answer 1

Step-by-step explanation:

arithmetic sequence means that every new term is created by adding a certain constant (here 2) to the previous term.

a27 = -1/2 = a1 + (n-1)×2 = a1 + 26×2 = a1 + 52

a1 = -52 1/2 = -105/2

an = -105/2 + (n-1)×2

What is the solution to Kamal's equation?

O 7
O no solution
O infinitely many solutions

Answers

Answer:

no solution

Step-by-step explanation:

3(x-8)=x+2x+7

3x-24=3x+7

there is no solution bc both sides, when simplified, that x is not defined.

you end up canceling the 3x in both sides and so,

Save and Exit

Answers

Answer:

Locate (0,-6), move up 2, right 1

Step-by-step explanation:

Hi there!

To graph a linear function, we first locate the-intercept, then graph the next point according to the slope.

We're given that the y-intercept is -6. The y-intercept occurs when x=0, so therefore, the point (0,-6) falls on the line.

Locate (0,-6)

Now, to graph the next point, we look at the slope. The slope in this case is 2. This means every time the line travels to the right by 1 unit, it travels up 2 units.

Move up 2, right 1

1/3(12-9y) distributive property

Answers

Answer:

4 - 3y

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] (12 - 9y) ← multiply each term in the parenthesis by [tex]\frac{1}{3}[/tex]

= 4 - 3y

The simplification of 1/3(12-9y) using distributive property is 4 - 3y

What is distributive property?

According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

For example, 2( x +y ) can be simplified as 2 × x + 2 × y

= 2x + 2y. This is distributive property.

Similarly, ⅓( 12- 9y) can be simplified as

(1/3 × 12) - (1/3 × 9y)

= 4 - 3y

Therefore 1/3(12-9y) is equivalent to 4 - 3y
