How do I graph 3x=-12y + 3. Need to know how to plot

1 answer:

6 0

Separate put the y on one side so that it would be 12y=3x+3, then divide the entire equation by 12 so you get y=(3/12)x+(3/12), and 3/12 is simplified to 1/4, so the equation would be y=(1/4)x+1/4 so the y intercept is 1/4 and the slope is 1/4.

ian invested an amount of money at 3% per annum compound interest. At the end of 2 years the value of the investment was £2652.2

Scorpion4ik [409]

Answer:

the amount of money Ian invested is P = £2,500

Step-by-step explanation:

The standard formula for compound interest is given as;

$A = P(1+r/n)^{nt} \\P = \frac{A}{(1+r/n)^{nt}} ...........1\\$

Where;

A = final amount/value

P = initial amount/value (principal)

r = rate yearly

n = number of times compounded yearly.

t = time of investment in years

For this case, Given that;

A = £2652.25

t = 2 years

n = 1 (semiannually)

r = 3% = 0.03

substituting the given values into equation 1;

$P = \frac{A}{(1+r/n)^{nt}} ...........1\\P = \frac{2652.25}{(1+0.03)^{2}} \\P = \frac{2652.25}{(1.03)^{2}} \\$

P = £2,500

the amount of money Ian invested is P = £2,500

The table shows the height of a softball that Hallie threw in the air. Is the relationship shown linear? Why or why not?

andrew11 [14]

Answer:

Not a linear relationship

Step-by-step explanation:

Given

The attached table

Required

Linear or not

To do this, we simply calculate the slope of the table at different intervals.

Slope (m) is calculated as:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Let:

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (0.5,7.2)$

So, the slope is:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{7.2 - 0}{0.5-0}$

$m = \frac{7.2}{0.5}$

$m = 14.4$

Let:

$(x_1,y_1) = (1,10.7)$

$(x_2,y_2) = (2,12.2)$

So, the slope is:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{12.2 - 10.7}{2 - 1}$

$m = \frac{1.5}{1}$

$m = 1.5\\$

See that the calculated slopes are not equal.

Hence, it is not linear
