Answer:
And if we solve for y we got:
And replacing we got:
And we got:
And for x we got:
So then the length would be 76 and the width we got 12.5
Step-by-step explanation:
For this case we have a rectangle. The perimeter is given by:
Where x represent the length and y the the width. We can set the following conditions:
And if we replace the conditions we got:
And if we solve for y we got:
And replacing we got:
And we got:
And for x we got:
So then the length would be 76 and the width we got 12.5
Answer:
2nd option because the number next to the x is the slope (3) and the added number is your intercept (4)
Step-by-step explanation:
Answer:
See attached
Step-by-step explanation:
Given function:
Table and graph are attached
Zeros are included in the graph
<u>Zero's are obtained:</u>
x = 0 ⇒ y = 8
y = 0 ⇒ Solving quadratic equation
- -2x² + 5x + 8 = 0
- x = (-5 ± √(25 + 2*4*8))/-4
- x = 3.608
- x = -1.108
So zeros are (0, 8), (3.608, 0) and (-1.108, 0)
Answer:
The larger ham is the better buy.
Step-by-step explanation:
In order to determine the better buy, divide both of the prices by their weight to get the price per pound of ham.
5.70/3 = 1.90 per lb
8.75/5 = 1.75 per lb
Therefore the 5 pound of ham is a better buy.
