Ivan is a software salesman. let y represent his total pay (in dollars). let x represent the number of copies of history is fun he sells. suppose that x and y are related by the equation 70x + 2100 = y.

answer the questions below.
note that a change can be an increase or a decrease.
for an increase, use a positive number. for a decrease, use a negative number.

what is the change in ivan's total pay for each copy of history is fun he sells?

what is ivan's total pay if he doesn't sell any copies of history is fun?

what is the original number? you forgot to add it.

d.) yes, because the volume of the cone is greater than the volume of the sphere

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

t= 1/3.
