1 journal = 280 grams
3 journals = 280 * 3
280 * 3 = 840
Total weight of 3 journals = 840 grams
Answer:
g = 15 - m/28
Step-by-step explanation:
let g = gasoline
let m = miles
since you can drive 420 miles with 15 gallons of gas, you can drive 28 miles with one gallon (= 420/15 = 28)
e.g.
you drive 100 miles, then you will have:
g = 15 - 100/28 = 15 - 3.57 = 11.43 gallons of gas left
you drive 240 miles:
g = 15 - 240/28 = 6.43 gallons
124.8 miles. 104/50=2.08. 2.08x60=124.8.
Answer:
<em>Question 1) </em>
The graph of
is attached to the answer.
The graph of such a functio lies in first and third quandrant such that the graph tends to 0 when x→∞ or when x→-∞ and graph tends to ∞ when x→0.
We can also show the values of this equation on a table:
<u> x-values</u> <u> y-values</u>
1/2 4
1 2
2 1
3 2/3
<em>Question 2)</em>
The graph of the equation
is attached to the answer.
we will get a upward parabola with this equation whose vetex is: (-1,-4).
The ordered pair on the graph could be shown with the help of a table:
<u>x-values</u> <u> y-values</u>
-1 -4
0 -3
-3 0
1 0
