Answer:
The table in the exercise can be completed with the next results:
- x y
-
2 <u>9</u>
-
4 <u>11</u>
-
6 <u>13</u>
-
8 <u>15</u>
Step-by-step explanation:
As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:
Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:
When x is 2:
When x is 4:
When x is 6:
When x is 8:
At last, <u>to obtain the graph you can use the formula made: y = x + 7</u>, and you'll obtain a graph like the attached picture, <em>where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7</em>.
To have infinitely many solutions they must describe the same line. So any multiple or fraction of the reference line would indeed describe the same line, and thus "intersect" at each and every of an infinite number of points.
2(x+y=4)
2x+2y=8 (is the same line as x+y=4)
Answer:
1/3 , 4/15 , 5/6
Step-by-step explanation:
All you have to do is plug the fractions in your calculator and you see that 1/3, 4/15, and 5/6 are repeating, but the others stop after only a couple of decimal places.
Hope this helps!
The amount of kerosene and gasoline produced is an illustration of equations.
<em>44.4 million barrels of gasoline and kerosene are produced</em>
Let
<em />
<em> Proportion of kerosene</em>
<em />
<em> Proportion of Gasoline</em>
<em />
So:
---- total barrels produced
The amount of Kerosene produced is:
The amount of Gasoline produced is:
So, the total production of both is:
<em>Hence, 44.4 million barrels of gasoline and kerosene are produced</em>
