Need please solving for x​

Mathematics
1 answer:
koban [17]3 years ago
6 0

Answer:

x = 15

Step-by-step explanation:

Corresponding sides of similar shapes are proportional to each other. Thus:

(10 + 2)/10 = (x + 3)/x

12/10 = (x + 3)/x

Cross multiply

12*x = (x + 3)*10

12x = 10x + 30

12x - 10x = 30

2x = 30

x = 30/2

x = 15

Answer:

  y = -x -12

Step-by-step explanation:

The slope of the line you want is the same as the slope of the line you have: -1. Then the point-slope equation of the line is ...

  y -k = m(x -h) . . . . . . line of slope m through point (h, k)

  y -(-7) = -1(x -(-5))

  y = -x -5 -7 . . . . subtract 7, eliminate parentheses

  y = -x -12 . . . slope-intercept equation

Change in speed  = (end speed) - (start speed)

                             =    (22 m/s)    -   (4 m/s)   =   18 m/s .


Magnitude of average acceleration =

                         (change in speed) / (time for the change) .

                     =                (18 m/s)  /  (3 sec)  =  6 m/s² .


That's about 0.61 G.
