Answer: 150
Step-by-step explanation:
30% = 0.3
100-30=70
70% = 0.7
0.7 X 500 = 350
500-350 = 150
Answer:
undefined
Step-by-step explanation:
To find the slope of the line between two points, use the slope formula
.
and
represent the x and y values of one point the line passes through, and
and
represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:
However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
Answer:
One ticket is $164. The expression is (5*19) + (5*164) or (5*19) + 5x
Step-by-step explanation:
19*5 = 95
915 - 95 = 820
820/5 = 164
The price of one ticket is $164.
Hope this helps. Have a nice day.
Answer:
3
Step-by-step explanation:
3 would be the degree of the polynomial since it has the highest degree.
Answer:
y=ln(x/(1-x))
Step-by-step explanation:
y=e^x/(1+e^x)
Cross multiply
y(1+e^x)=e^x
Distribute
y+ye^x=e^x
Put anything with x on with side and everything without x on opposing side:
y=e^x-ye^x
Factor right hand side
y=(1-y)e^x
Divide both sides by (1-y)
y/(1-y)=e^x
Use natural log.
ln(y/(1-y))=x
The inverse is
y=ln(x/(1-x))
