Answer:

y=-3x-1

Step-by-step explanation:

12x+4y=-4

Slope intercept y=mx+b

Subtract 12x from both sides

4y=-4-12x

Divide each side by 4

y=-1-3x then just reorder to match slope intercept form

y=3x-1

The graph of a proportional relationship passes through (12,16) and (1,y). find y

anastassius [24]

Answer:

4/3

Step-by-step explanation:

A proportional relationship is a relationship that crosses through the origin or (0,0). This means the slope of the line can be found by subtracting the points (12,16) and (0,0) in the slope formula.

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{16-0}{12-0}= \frac{16}{12}=\frac{4}{3}$

So the slope is 4/3 and must be the value between any two points on the line.

This means the function moves from (0,0) to (1, 4/3).

Compute Δy and dy for the given values of x and dx = Δx. (Round your answers to three decimal places.) y = ex, x = 0, Δx = 0.4

kobusy [5.1K]

Answer:

0.492

Step-by-step explanation:

According to the given situation, the calculation of Δy and dy is shown below:-

$y = e^x, x = o, \Delta x = 0.6$

$dy = f'(x) = e^x$

$dy = e^x dx$

$= e^x (0.4)$

$dy = 0.4e^x$

$\Delta y = f(0.4) - f(0)$

$= e^{0.4} - e^0$

Now we use the scientific calculator or spreadsheet to determine the exponential value

= 1.491824698 - 1

= 0.491824698

= 0.492

Therefore for computing the Δy and dy we simply applied the above formula.

Hence, the answer is 0.4918
