Answer:
1.) y = 1.10(x – 1) + 1.35
Step-by-step explanation:
When x pounds of apples are purchased, the number of "additional" pounds is (x-1). The cost of those additional pounds is then added to the cost of the first pound to get ...
y = 1.10(x -1) +1.35
_____
<em>Comment on the function rule</em>
Personally, I think it is easier to write the rule as y = 1.10x +0.25, considering the first pound to have a $0.25 premium added to its otherwise $1.10 cost. This saves an operation when evaluating the formula for some value of x.
8×9＝72
5×8＝40
So the answer is 8
Hi!
Let's just take this part by part.
The sum of seven is the first part written. You can deduce from that, that it's 7 + something.
The next part is the quotient of a number x and 8. A quotient is the result of something being divided, so we can figure out that it's x / 8.
Putting it all together, you get the expression as 7 + x / 8.
Hope this helped!
The limand is continuous at
, so you can directly substitute

Did you mean to write
in the denominator by any chance? In that case, you would instead have
Corresponding parts of corresponding triangles are congruent and angle additional postulate ?
