Answer:

2100 units

Step-by-step explanation:

We want to find the y-intercept of the function y=-15x+2100  which can be used to model the height, y, of a parachute jumper x seconds after she jumps from an airplane.

To find the y-intercept, you substitute x=0 into the equation.

y=-15(0)+2100

Multiply by zero to get:

y=0+2100

Add zero to obtain:

'y=2100

Therefore the y-intercept, which is the initial height is 2100

Shu Yi can't resist a sale. She recently bought a dress for $93 after it had been discounted 25%. She also purchased shoes that
klemol [59]
Dress: 93$ at 100-25%=75%
-> divide the marked down cost by the percentage to get the cost of a single percent and then multiply it with the markdown again to get the saved cost
93/75*25=93/3*1=31*1=31$
shoes 119$ at 100-15%=85%
119/85*15=119/17*3=7*3=21

add both savings together for the full sum: 31+21=52$
