$15 more, than twice Friday's earnings
d is how much he earned on Friday
s is how much he earned on Saturday
2d + 15 = s
Answer:
The values of k are 2/3 and -1
Step-by-step explanation:
Product of zeros = αβ= constant / coefficient of x^2 = 4/k
Sum of zeros =α+β = - coefficient of x / coefficient of x^2= -4/k
Given
Consider a= α and b= β
can be written as if we add in the above equation.
Putting values of αβ and α+β
The values of k are 2/3 and -1
Graphs of proportional relationships pass through the origin because that's were the graph starts
1 yard is 36 inches so 3 divided by 36 = 12 so 12 inches = one third yard
get the point of discontinuity we proceed as follows;
f(x)=x+5/x^2+3x-10
f(x)=4x+5x^2-10
this can be written is such a way that they have the same denominator, here we shall have:
f(x)=(4x^3-10x^2+5)/x^2
The denominator= x^2
The numerator=4x^3-10x^2+5
The discontinuity is at the point x=0
the removable discontinuity is the the point x=2
