Answer: $214.2

Step-by-step explanation:

Given : The hourly rate = $7.65

The total hours work done by Maureen = 28

Now, the total amount she earn last week will be :-

\text{Total amount=Number of days}\times\text{Hourly rate}\\\\\Rightarrow\ \text{Total amount}=28\times\$7.65\\\\\Rightarrow\ \text{Total amount}=\$214.2

Hence, the total amount she earn last week=$214.2

Answer:

a) P(0, <u>2</u>), Q(<u>4</u>, 0)

b) Please find attached the plot of the points P and Q on a chart made with MS Excel

c) Please find the graph of the line that represent the function 4·x + 2·y = 8 for values of x from -2 to 3 made with the Insert Chart feature on MS Excel

Step-by-step explanation:

The given equation for the line is 4·x + 2·y = 8

a) The coordinates of P = P(0, _)

Therefore, the point 'P', which is the point where the variable y = 0, is the point the (straight line) graph intercepts the x-axis (the x-intercept)

When y = 0 from the given equation, we get;

4·x + 2·y = 8

At the point y = 0;

4·x + 2 × 0 = 8

x = 8/4 = 2

x = 2

∴ The coordinates of P = P(0, _) = P(0, <u>2</u>)

Similarly, when x = 0, we get;

4·x + 2·y = 8

At the point x = 0;

4 × 0 + 2·y = 8

y = 8/2 = 4

y = 4

∴ The coordinates of Q = Q(_, 0) = Q(<u>4</u>, 0)

b) Rewriting the given equation in terms of 'y' gives;

y = (8 - 4·x)/2 = 4 - 2·x

y = 4 - 2·x

With the help of MS Excel, the points P and Q are plotted in the attached graph

c) The line of the graph of the function 4·x + 2·y = 8 for values of x from -2 to 3 can be added by Changing the Chart Type to 'Scatter with Smooth Lines and Markers' within MS Excel as presented in the included graph of the line.

Math definitely isn't my greatest subject, if anyone knows how to do this and can explain it to me please help!
Law Incorporation [45]

Answer:

y-1 = 5/3(x-3)

Choice C

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

(3,1) (6,6)

m = (6-1)/(6-3)

m = (5/3)

the point slope form of a line is given by

y-y1 = m(x-x1)

You have point (3,1)

y-1 = 5/3(x-3)

Choice C
