Step-by-step explanation:
We have got the lines :
Both lines intercept the x-axis in the point :
In all point from x-axis the y-component is equal to 0.
We replace the I point in the lines equations:
From the first equation :
From the second equation :
Then 
Finally :
y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc
Answer:
The total price of the Rice sack is Rs 1920.
Step-by-step explanation:
The price of 1 sack of rice = Rs. 1,850
Wages Charge = Rs. 70
Now, the total price = Price of the Rice + Wages Charge
= Rs. 1,850 + Rs. 70
= Rs. 1920
or, the total price = Rs. 1920
Hence, the total price of the Rice sack is Rs 1920.
<u>Answer</u>
The first student was right.
The length of the long side is at least 13 inches.
<u>Explanation</u>
The perimeter of any figure is the distance all round.
Perimeter of a rectangle = 2(l+w). Where l is length and w is the width.
2(l + w) ≥ 30
2{(x-3) + 2} ≥ 30
2(x-3+2) = 30
2(x - 1) ≥ 30
x - 1 ≥ 15
x ≥ 16
When x = 16,
l = 16-3
= 13 inches
The length of the long side is 13 inches. The first student was right.
