Y = -3x  + 6

y - 6 = -3x

-1/3 y + 2 = x

z = x  -3

z = -1/3 y + 2 -3 = -1/3  y  - 1 

set z = 0

-1/3 y = 1

y = -3

set y = 0

z = - 1

Answer:

We are given the parametric equations as:

x = t  

y = -3t + 6  

z = t - 3

Clearly we could find a relationship between x and y as:

y= -3x+6----(1)

since x=t

Also we can find a relationship between x and z as:

z=x-3-----(2)

Now we can write a relationship between y and z as:

from equation (2) we have:

x=z+3 and putting this value of x in equation (1) to obtain:

y=-3(3+z)+6

y= -3z-3

Now we can consider three points as:

When x=1    y=3    z=-2

Rose and Dennis each open a savings account at the same time. Rose invests $2,600 in an account yielding 4.1% simple interest, a
vodka [1.7K]
The formula is
A=p (1+rt)
A future value
P present value
R interest rate
T time in years

Rose investment
A=2,600×(1+0.041×9)
A=3,559.4

Dennis investment
A=2,200×(1+0.057×9)
A=3,328.6

So Rose investment is greater than Dennis investment by
3,559.4−3,328.6=230.8

Hope it helps!

A plumber chargers $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost,
daser333 [38]

25$ is the flat fee.  50$ is the amount charged per hour.  Therefore the equation is C=25+50h where c is the total cost and h is the amount of hours.  

C=25+50h

To find the amount of money for 8 hours simply plug in 8 for h and you get 400.  Don't forget to add the flat fee of 25.  The total cost for 8 hours of service is 425.

To find the amount of money for 10 hours of work, plug in 10 for h and you get 500.  Add 25 to 500 and you get 525 for a total of 10 hours of work.

Hope this helped...
