Substitute each value of x in y=2x-3

so,

first box (-2)
y= 2(-2)-3
y= -4-3
y= -7

second box (0)
y= 2(0)-3
y= 0-3
y= -3

third box (3)
y=2(3)-3
y=6-3
y=3

Answer:

y= -5/2 + 17

Step-by-step explanation:

y=mx+b

A group of hikers walks 3 miles east and then 1 mile north. After taking a break, they then hike 4 miles east to their final des

geniusboy [140]

Answer:

The vector that describes their hike from their starting position to their final destination is $\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$ .

Step-by-step explanation:

In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:

(i) A group of hikers walks 3 miles east and then 1 mile north:

$\vec r_{A} = 3\,\hat{i}+1\,\hat{j}\,\,\,[mi]$

(ii) After taking a break, they then hike 4 miles east to their final destination:

$\vec r_{B} = 4\,\hat{i}\,\,\,[mi]$

The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:

$\vec r = \vec r_{A}+\vec r_{B}$ (1)

$\vec r = (3\,\hat{i}+1\,\hat{j})+4\,\hat{i}\,\,\,[mi]$

$\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$

The vector that describes their hike from their starting position to their final destination is $\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$ .

B 6x+7 3x+c 2x-1 What is the value of c in degrees

andreev551 [17]

Answer:

1.x=15

2.<A=29

Step-by-step explanation:

(2x-1)+(3x+9)+(6x+7)=180

2x-1+3x+9+6x+7=180

11x+15=180

11x=180-15

11x=165

x=165/11

x=15

2.<A=2x-1

<A=2*15-1

<A=30-1

<A=29
