Answer:
Step-by-step explanation:
So let's think about what values you can take square root of...
anything but negative values!
So the first one is not correct because you can also take square root of 0,
squareroot of 0 is 0.
So because of this, C and D are both correct, E is correct because root x is an increasing function. B is incorrect because (0,0) is an intercept.
Answer:
The lowest fraction it can be simplified to is 1/8.
The companies being considered are:
The company that is concerned with corded telephones
The company that is concerned with cellphones
Let x represent the number of years since 2002 and y represent the total number of accounts
From the information given,
Considering the first company,
Initial number of accounts = 946 x 10^6
The number of accounts fell by approximately 28 million per year. This means that in x years, the number of accounts that would have been lost is
28 x 10^6 * x
= - 28x x 10^6
It is negative because it is reducing
The slope intercept form of a linear equation is expressed as
y = mx + c
where
m = rate of change
c = y intercept of value of y when x = 0
By comparing with the given scenario,
<h3>
Answer: 90 g of butter </h3>
================================================
Work Shown:
450 g of butter = 60 biscuits
450/60 g of butter = 60/60 biscuits ... divide both sides by 60
7.5 g of butter = 1 biscuit
This means each biscuit needs 7.5 grams of butter
Multiply both sides by 12 to get
7.5 g of butter = 1 biscuit
12*7.5 g of butter = 12*1 biscuit
90 g of butter = 12 biscuits
