What do the y intercept and the slope mean in the context of the example problem y=-4x+20

Mathematics

PtichkaEL [24]3 years ago
3 0

Answer:

Therefore,

Slope = -4\\\\y-intercept=20

Step-by-step explanation:

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

There are two intercepts:

x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.

y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.

Given:

y=-4x+20

We have General Equation for POINT-SLOPE form for a line is given as

y=mx+c

where,

m = Slope of Line

c = y-intercept

On Comparing the given Equation with Point-Slope form we have

m = Slope = -4\\\\c=20

Therefore,

Slope = -4\\\\y-intercept=20

How do you write a function of t that represents the situation(sales $10,000 increase by 65% each year)?
Shkiper50 [21]

Answer:

  s(t) = 10000·1.65^t

Step-by-step explanation:

The general form of an exponential model is ...

  f(t) = (initial value) × (1 +(fractional change))^t

where the fractional change can be positive or negative and t is the number of time units. Each time unit will correspond to the period required for the fractional change.*

__

For your problem, you have (initial value) = 10,000 and (fractional change) = 65% = 0.65 with time units of 1 year. Your function for sales (s) will then be ...

  s(t) = 10000·1.65^t

_____

* The business regarding time units has to do with problems where you get a description like "increased 30% in 4 hours." Then, if t is in hours, the multiplier of the initial value looks like 1.30^(t/4).

Based on these results, express the probability that the next customer will pay with something other than a credit card as a fra
Marina CMI [18]

Answer: 99/130

Payment made by any method except credit card is 95+4=99 and altogether there is three payment method including a credit card which sums up to 130.

So the probability is 99/130.

How many books can you get in a storage bin that is 4 feet high and 9 feet long and 11 feet wide
Ugo [173]
Well, this depends on the size of the books. We can find the volume of the bin by using...
V=bh or l x w x h
So, 9 times 11 is 99.
99 times 4 is 396, which is the volume.
You did not specify the size of the books, so all we can say is that the volume of the bin is 396 cubic feet.
