Using the values provided in the table, the only equation that would be valid would be the following...
y = 12.5x + 15
That is because if we substitute any value provided in the table for x , this equation will correctly output the y value shown in the table for the attached x-value. For example, in the table 5 nights (x = 5) should have a total cost of 77.5 (y = 77.5)... Therefore, if we substitute 5 for x in the function it should give us 77.5 which it does.
Let x-------------> amount added <span>to each side </span>A-------------> area increased----------> 84 ft²
we know that A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x² 50+15x+x²=84----------> x²+15x-34=0 <span>solving the second order equation </span>x1=-17 x2=2
D-chloroplast. Chloroplasts are found in plant cells and carry out the process of photosynthesis, they are the equivalent of the “power house of the cell”, the mitochondria
Ratio of height of the flag pole to the length of its shadow = 40:9.6 = 25:6 Ratio of height of the building to the length of its shadow = x:48 = 25:6 x/48 = 25/6 x = (48 x 25)/6 = 1200/6 = 200
Therefore, the height of the building is 200 feet.
