7 x 500,080=7 x (500,000+80)=7 x 500,000+7 x 80=3,500,000+560=3,500,560

Enter a recursive rule for the geometric sequence.

Jlenok [28]

Answer:

$x_{n} = 5 \ * \ (-2)^{n-1}$

Step-by-step explanation:

Given the geometric sequence:

5, −10, 20, −40, ...

The first term is a = 5

And the common ratio = r = -10/5 = -2

The general rule of geometric sequence is

$x_{n} = a \ * \ r^{n-1}$

So, the rule for the given geometric sequence is:

$x_{n} = 5 \ * \ (-2)^{n-1}$

9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing

Andre45 [30]

Step-by-step explanation:

Hey there!

The equation, of a st. line that passes through point (5,9) is,

$(y - y1) = m1(y - y1)$

Put the values,

$(y - 9) = m1(x - 5)$

It is 1st equation.

Now, another equation is,

y = 3x-1.........(ii)

Comparing the equation with y = mx+c.

Slope (m2)= 3

As per the parallel lines,

m1=m2=3

Putting,

the value of m1 in equation(i)

(y-9)= 3(x-5)

y-9= 3x - 15

y = 3x - 6.

So, Krista equation is correct.

Hope it helps...

Does anyone know how to answer this?

Answer: Yes. The answer is: [C]: "1 " .
______________________________________________
Explanation:
______________________________________________
The equation for a line, in "slope-intercept format" , is:
______________________________________________
                      →    y = mx + b ;
______________________________________________
                 in which "b" = the y- intercept; or the value of 'x' when "y = 0" ;
                               "m" = the slope; which is also the coefficient of "x".
____________________________________________________
In "slope-intercept format", the "y" remains isolated on the left-hand side of the equation, with no "coefficient" (other than the "implied coefficient" of "1").
__________________________________________________________

So, if the two particular lines are parallel, and we know that the slope is "1" for EACH line; (that is, "m = 1" for each line); then the PRODUCT of the two slopes is:
____________________________________________________________
                       →    m² = m * m = 1² = 1 * 1 = 1 .
____________________________________________________________
                        → The answer is: Answer choice: [C]: "1" .
____________________________________________________________
