40%
Because, 2/5 equals 4/10. 10x10=100, so 4x10=40, so 40%.
If xy=0 we assume x and y equal 0
so
the zeros are wehre f(x)=0
0=5(2x-5)(5x+4)
set each to zero
5 is not equal 0 so we don't do that
0=2x-5
5=2x
5/2=x
0=5x+4
-4=5x
-4/5=x
zeroes at x=5/2 and -4/5
Answer:
x<-10
Step-by-step explanation:
10-2.5x>35
2.5x>10-35
2.5x>-25
x>-25/2.5
x>-10
x<-10
Answer:
1.) $10.50 + $3.50n
2.) Replace the variable with the given number. In this case, the given number is 20.
n = 20
$10.50 + $3.50(20)
$10.50 + $70 = $80.50
So, the total cost to visit the fair is $80.50.
The table indicates a y-value of 115 when x = 0. That corresponds to the y-intercpt of the equation.
The table values increase by 64 for each increase of 2 in x-value. That corresponds to the slope (32) of the equation.
Yes, the equation and the table represent the same function.
