Answer:

slope = -1/3, y-intercept (0, -3), x-intercept (-9 , 0)

Step-by-step explanation:

3 - x = 3(y + 4)

3 - x = 3y + 12

3y = 3 - x - 12

3y = -x -9

y = -1/3 x - 3

slope = -1/3

when x = 0 (y-intercept)

y = -1/3 × 0 - 3

y = -3

y-intercept (0, -3)

when y = 0 (x-intercept)

0 = -1/3 x - 3

1/3 x = -3

x = -9

x-intercept (-9 , 0)

If P = (-1,-1), find the image

<h3>Answer:     (-1, 1)</h3>

=========================================================

Explanation:

The rotation rule we use is (x,y) \to (y, -x)

The x and y coordinates step places, then the second coordinate (after the swap) changes in sign from positive to negative, or vice versa.

For example, the point (5,7) rotates to (7, -5). As another example, (2,-1) becomes (-1, -2). As another example, (-9,4) becomes (4,9).

----------------------------------

In our case, the point (-1,-1) will rotate to (-1, 1)

Note: A 270 degree counterclockwise rotation about the origin is the same as a 90 degree clockwise rotation about the origin. Refer to the diagram below.

Ian and April wish to have 8,000 available for the wedding in six years how much money should be set aside now at 6% compounded
ira [324]

Answer:

\$5,586.42  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=6\ years\\ A=\$8,000\\ r=0.06\\n=12  

substitute in the formula above  

8,000=P(1+\frac{0.06}{12})^{12*6}  

8,000=P(1.005)^{72}  

P=8,000/(1.005)^{72}  

P=\$5,586.42
