I need help with this table if anyone can help me it would be my blessing to you and could you maybe show me how to do it?

Ghella [55]

given that

3m -9n =24

when n= -1

substitute it in the equation

thus

3m -9(-1)=24

solving for m

3m +9 =24

3m =24-9

3m=15

dividing through by 3

3m/3 =15/3

m =5 . thus when n= -1 , m=5

also put n=1 into the equation

3m -9(1) =24

3m -9 =24

3m= 24+9

3m =33

dividing through by 3

3m/3 = 33/3

m=11

thus when n= 1, m=11

lastly, put n= 3 into the equation

3m -9(3) =24

3m -27 = 24

3m = 24+27

3m =51

dividing through by 3

3m/3 =51/3

m =17. Thus when n = 3 , m= 17.

1) Anna and Jason have summer jobs stuffing envelopes for two different companies. Anna earns $20 for every 400 envelopes she fi

Margarita [4]

Answer:

The answer is below

Step-by-step explanation:

A) i)

For Anna initially, she has $0 from making 0 envelopes. Anna earns $20 for every 400 envelopes. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (400, 20). Using the equation of a line:

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-0=\frac{20-0}{400-0}(x-0)\\\\y=\frac{1}{20} x$

The table is:

x: 200 400 600 800 1000

y: 10 20 30 40 50

ii)

Jason has $0 from making 0 envelopes. For every 250 envelopes he has $10. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (250, 10). Using the equation of a line:

$y-0=\frac{10-0}{250-0}(x-0)\\\\y=\frac{1}{25} x$

x: 200 400 600 800 1000

y: 8 16 24 32 40

The graph is plotted using geogebra online graphing

b) From the table of Anna and Jason we can see that Anna makes more stuffing than Jason for the same number of envelopes.

c) Anna has a savings of $100 initially. Hence this can be represented by the points (0, 100) and (250, 10). Using the equation of a line:

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-100=\frac{20-0}{400-100}(x-0)\\\\y=\frac{1}{15} x+100$

Therefore from the graph there is a y intercept at 100. That is the earnings starts initially is $100.

The equation of a line is given as y = mx + b, where m is the slope and b is the y intercept (initial value of y at x = 0)

For the first graph, the slope is 1/20 with an initial value of 0 while for the second graph the slope is 1/15 with an initial value of 100

D) The trend line pass through the points (10, 10) and (100, 40), hence:

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-10=\frac{40-10}{100-10}(x-10)\\\\y-10=\frac{1}{3} (x-10)\\\\y=\frac{1}{3}x+\frac{20}{3}$
