Question:
Give all the x and y intercept of the function
Answer:
The x intercepts are x = 5 and x = -4
The y intercept is at y = -2
Step-by-step explanation:
Factorizing the numerator of the expression we find the x intercepts as follows;
Therefore, the x intercept are
x = 5 and x = -4
To find the y intercept, we put x = 0 to get y = -2
Therefore, the y intercept is at y = -2
Factorizing the denominator we find the values for which the equation is undefined
2·x³ + 2·x² - 34·x + 30 = 2·(x-1)·(x-3)·(x+5) which gives
x = 1, 3 and -5.
y=x4−7; y=2
Y=2 (2)=x.4-7
2+4x-7
4x-7=2 get the variable alone by doing the same thing to both sides
4x=9
4x/4=9/4
y=9/4
x=9/4
Answer:
$75
Step-by-step explanation:
Cost = $500
Sam has to pay a 15% tax
To compute his tax, we use the step outlined bellow
tax= 15/100*500
tax= 0.15*500
tax=$75
Hence his tax is $75
Answer: Last option.
Step-by-step explanation:
Let be "s" the unit price of the smaller box and "l" the unit price of the larger box.
According to the information given in the exercise, the smaller one is a 17-ounce box which costs $2.89. Therefore, in order to find the value of "s", you need to divide $2.89 by 17 ounces. This is:
You know that the larger box has 24 ounces and it costs $3.29.
Therefore, in order to find the value of "l", you need to divide $3.29 by 24 ounces. This is:
Finally, find the difference:
or 
Therefore, you can conclude that the larger box is better buy because it is approximately 3.3 cents cheaper per ounce.
