A pattern rule for a sequence is Start at 8, double each number and add 2. what are the first five numbers

2 answers:

8 0

(8 x 2) + 2 = 18 (18 x 2 ) + 2 = 38 (38 x 2) + 2 = 78 (78 x 2) + 2= 158.... can you see the pattern? All numbers end in 8. Thats the only pattern I see.

8, 18, 38, 78, 158. Just double the last number and add two to that (edited)

Part A
The given line passes through (-2,2) and it is parallel to the line

$4x - 3y - 7 = 0$

We need to determine the slope of this line by writing it in slope -intercept form.

$3y = 4x - 7$

$y = \frac{4}{3} x - \frac{7}{3}$
The slope of this line is
$\frac{4}{3}$

The line parallel to this line also has slope

$m = \frac{4}{3}$

The equation is

$y = \frac{4}{3} x + c$

We substitute (-2,2)

$2 = \frac{4}{3}( - 2) + c$

$c = 2 + \frac{8}{3} = \frac{14}{3}$

The required equation is

$y = \frac{4}{3} x + \frac{14}{3}$

PART B

The given line is

$4x - 3y - 7 = 0$

The slope of this line is
$\frac{4}{3}$

The slope of the line perpendicular to it is

$m = - \frac{3}{4}$

The equation of the line is

$y = - \frac{ 3}{4} x + c$

We substitute the point, (-2,2)

$2= - \frac{ 3}{4} ( - 2) + c$

$2= \frac{ 3}{2} + c$

$c = 2 - \frac{3}{2} = \frac{1}{2}$

The equation of the perpendicular line is

$y= - \frac{ 3}{4} x + \frac{1}{2}$

What is the slope of the line shown in the graph? 1) -1 2) -2 3) -1/2 4) 2

Travka [436]

I believe it would be -2 since you use rise over run. That would be -2/1

What is 6/10 simplified

Komok [63]

6/10 = 3/5

Simply divide the numerator and denominator of 6/10 by 2. 6/10 is the same as 3/5.

1. F(3)= -2(3)-5

-6-5

F(3)=-11

2. F(3)= -2(3)^2-4

-6^2-4

36-4

F(3)=32

3. F(x)=−2x−5

For: x=−2, f(x) is:f(−2)=(−2×−2)−5=4−5=−1

For: x=−1, f(x) is:f(−1)=(−2×−1)−5=2−5=−3

For: x=1, f(x) is:f(1)=(−2×1)−5=−2−5=−7

For: x=2, f(x) is:f(2)=(−2×2)−5=−4−5=−9

The Range is:

{−1,−3,−7,−9}

4. -80, -110
