Y=3x+50
y=10x

coordinate points aren't necessary to solve a problem with the slope and y intercept given.

Answer:

The system of equations is equal to

y=3x+50

y=10x

Step-by-step explanation:

Let

x------> the number of gym visits per month

y------>  the total cost per month

we know that

The equation of the line into slope-intercept form is equal to

y=mx+b

Plan 1

y=3x+50 -------> equation A

where

the slope m is equal to m=3\frac{\$}{visit}

the y-intercept b is equal to b=\$50

Plan 2

y=10x -------> equation B

where

the slope m is equal to m=10\frac{\$}{visit}

Write 3.9 as a mixed number?
LiRa [457]

Answer:

3 9/10

Step-by-step explanation:

First the "whole number" part is 3.

The decimal part is 0.9. To convert that, keep the 9. Since the 9 is in the tenths place, it is 9/10.

Add them together: 3+9/10= 3 9/10

Final answer 3 9/10

Hope this helps

at 7 p.m. the temperature is 72 degrees F at 10 p.m. it is 52 degrees find the average rate of change in temperature
mart [117]
We will assume that we have a function relating between the time and the temperature. Any point in this function can be expressed as (x,y) where x is the time and y is the temperature (any point is expressed as (time, temperature)).

We have two points given:
<span>At 7 p.m. the temperature is 72 degrees F: First point is (7,72)
</span><span>At 10 p.m. the temperature is 52 degrees F: Second point is (10,52)

The rate of change is simply the slope of this function, this slope can be calculated as:
rate of change = (y2-y1) / (x2-x2)
we have y2= 52, y1= 72, x2= 10 and x1= 7

Substituting in the equation, we can calculate the rate of change as follows:
rate of change = (52-72) / (10-7) = -6.667 degrees/hours
Note: The negative sign indicated a DECREASE in the temperature.</span>

a company is considering purchasing the mineral rights to two different mountains. the probability that it will purchase the min
Licemer1 [7]

The probability of purchasing mineral rights to exactly one of the two mountains is 0.51.

<h3>What is probability ?</h3>

Probability turned into added into arithmetic to are expecting the possibility of an occasion occurring. Probability essentially approach how in all likelihood it's miles that some thing will happen. This is the fundamental principle of possibility and is likewise utilized in possibility distributions to examine feasible consequences of random experiments.

<h3>Calculation</h3>

Given information:

A company is considering purchasing materials:

The probability of purchasing mineral rights

Form the first mountain P1 = 0.55

From the second mountain P2 = 0.4

As the decision is made independently

So, P(P2∩ notP1) = 0.55 * 0.6

P(P2∩ notP1) = 0.33

Similarly, the value of

P(P2∩ notP1) =0.4 * 0.45

P(P2∩ notP1) = 0.15

Hence ,

P = 0.33 + 0.18

P = 0.51

Hence , the probability of purchasing mineral rights to exactly one of the two mountains is 0.51.
