75 extra minutes because $61.20-$49.95=$11.25 and $11.25/$0.15=75.
Answer:
Key features: the functions can not be parallels, this means that their respective slopes can not be equal or multiple to the other
Step-by-step explanation:
Take for instance 2 linear functions, and
If they intersect in some point in the space, say that is
Then (x1,y1)=(x3,y3), (x2.y2)= (x3,y3)
So, we can compare the two functions and get the following result;
It tells us that if M=m, we get an error, meaning that the functions are in fact parallels and there is no way that they meet in some point.
hope this helps!
Alex can buy at most 4 pounds of tomatoes
Let:
a represent pounds of tomatoes to buy
3a represent pounds of black beans to buy
Total cost of each ingredient that can be bought = number of pounds x price per pound
Tomatoes = a x $1.60 = 1.60a
Black beans = 3a x $1.70 = 5.1a
1.60a + 5.1a = 26.80
Add similar terms
6.7a = 26.80
Divide both sides of the equation by 6.7
a = 4 pounds

There were 340,000 cattle placed on feed
How many of the 340,000 cattle placed on feed were between 700 and 799 pounds?
Given the fraction of total cattle for 700 - 799 pounds is 2/5
Let x be the number of cattle between 700 - 799 pounds
We make a proportion using the fraction
Cross multiply it and solve for x
340000* 2 = 5x
680000 = 5x
Divide by 5 on both sides
So x= 136,000
There were 136,000 cattle between 700 and 799 pounds
