Answer:

See below  

Step-by-step explanation:

(1)  t = 5c + 35  

(2) t = 10c

(a) Create a table containing a few values of x and y

  <u>t </u>    <u>5c + 35 </u>  <u>10c</u>  

  0        35          0

  2        45        20

  4        55        40

  6        65        60

  8        75        80

10         85      100

(b) Draw your axes

You should scale your axes so the graph covers most of the plot area.

The slopes of your lines are so steep that, without scaling, they will be quite steep, and it will be difficult to tell where they intersect.

The independent variable is c, so the c-axis is horizontal. The dependent variable is t, so it goes on the vertical axis.

Let the c-axis run from -2 to 12 and the t-axis from -20 to 120.

Divide the axes into convenient intervals for ease of reading (I chose units of 2 for the c-axis and 20 for the t-axis).

(2) Plot your points

Draw dots at the coordinates of each point.

(3) Draw the graphs

Draw straight lines through the points.

Extend the line in both directions to the edges of the plot area.

Your graph should look like the figure below.

With the scaled axes, it is easy to see that the two lines intersect at (7, 70).

BARSIC [14]

Answer:

Mean= 8.5

Median= 6

Step-by-step explanation:

3,4,5,6,6,7,9,28

Median= Middle (If two middle number, add and divide by 2)

Mean= (3+4+5+6+6+7+9+28) ÷8

A 32 year old mother realized that her age is twice the sum of her two children's ages. Her son, Jose is two years older than he
dexar [7]

Answer:1,15 2,14 3,13 4,12 5,11 6,10 7,9 8,8 {x,y}

Step-by-step explanation:

There would be multiple answers for this question so what you have to do is find what doubles to 32 which would be 16 so you just have to find two numbers that add to 16 so the answers could be; 1,15 2,14 3,13 4,12 5,11 6,10 7,9 8,8

HHHHHHHHHHHHHHHHHHHHHHHHHHHHEEEEEEEEEEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPPPPPPPPPPP 30 POINTS
Vinvika [58]

Answer:

7.28 units

Step-by-step explanation:

Using the Pythagorean theorem, a^{2} + b^{2} = c^{2}, we get:

2^{2}+7^{2}=c^{2}\\4+49=c^{2}\\53=c^2\\\sqrt{53}=c\\c=\sqrt{53}

\sqrt{53} ≈ 7.28

If 3t-7=5t, then 6t =
Natalija [7]
The answer is:  " -21 " .
__________________________________________
We are asked to solve for: "6t" ; which is: "6 * t" .
__________________________________________
Given:  3t − 7 = 5t ;  Solve for "t" ; then solve for "6t" ;

     3t − 7 = 5t ;   Subtract "3t" from each side of the equation;
____________________________________________
    3t − 7 − 3t  =  5t − 3t ;

to get:  -7  = 2t  ;

Divide EACH side of the equation by "2" ; to isolate "t" on one side of the equation; and to solve for "t" ;

-7/2 = 2t / 2 ;

-3.5 = t  ;  ↔  t = - 3.5 ;
____________________________________________
Now, solve for "6t" ;

  6 t = 6*(-3.5) = - 21 .   The answer is:  " -21 " .

The sum of three consecutive even integers is 642. What are the integers? (Show your work too please)
Oliga [24]

Answer:

212,214,216

Step-by-step explanation:

n+n+2+n+4=642

add the n's and 2 and 4

3n+6=642

subtract 6 from both sides

636 divided by 3

you get 212 then add 2 twice.
