4 ten thousands is the same as how many tens.
=> Okay, let’s do this:
=> Let’s first show the scientific notation of the given number
=> how many tens are there in 10 000 (10 000 / 10) = 1000
Thus there are 1000 tens in 10 000
=> 10 x 10 = 100 * 10 = 1000 * 10 = 10 000
=> 4 x 10^4
Let’s try checking if we have the correct answer
=> 4 x 10 000
=> 40 000

Four ten thousands is the same as:
Four thousand tens
Heard of the commutative property where you can rearrange the multiplicands and you end up with the same product?

4 * 10 * 1000 = 4 * 1000 * 10
4 * 1000 = 4000 tens

Answer:

a) P(0, 2), Q(4, 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, 2)

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(4, 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.
