It's A because if you divide any number of hours and it's corresponding distance from data table shown in A by a number to get one hour you get a distance of 25 kilometers, for example ; 2 hours and 50 kilometers, divide it by 2 to get 1 hour and 25 kilometers. Or 6 hours and 150 kilometers divided by 6 to get 1 hour and 25 kilometers Therefore it is 25 kilometers per hour .

1. Segment AB has the coordinates given.
denpristay [2]

The first image has a coordinate of  A'(1, 6) B'(-3, 7)

<h3>How to calculate the coordinates of an image after a translation?</h3>

Translation can be defined as movement in a straight line.

Given the rule: (x,y) → (x + 3, y - 1) and A(-2,7) B(-6,8)

That means:  A(x = -2, y =7) B(x = -6, y = 8)

Thus the translation will be:

A'(-2 +3, 7-1) B'(-6+3, 8-1)  = A'(1, 6) B'(-3, 7)

Therefore, the coordinate of the image is  A'(1, 6) B'(-3, 7)

Many calculators use "E" to signify "×10^( )". Thus ...

... 1.3E-2 = 1.3×10^(-2)

This number in scientific notation is equivalent to the standard form number ...

Can anyone help me I was self isolating when my class was taught this and I can't get in contact with my teacher
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

3x +2y = 13   -----------------(i)

x + 2y = 7    ----------------(ii)

Multiply the equation (ii) by (-1) and then add.

(i)              3x + 2y = 13

(ii)*(-1)      <u>-x    - 2y = -7 </u>        {Now, add and y will be eliminated}

                 2x       = 6

                        x = 6/2

x = 3

Plug in x = 3 in equation (i)

3*3 + 2y = 13

  9 + 2y = 13

         2y= 13 - 9

         2y = 4

           y = 4/2

y = 2
