Leni [432]

Answer:

$5.39

Step-by-step explanation:

In order to solve for this equation, we are going to multiply 7.70 by 0.3 to find how much money was taken which was 2.31.

Subtract2.31 from 7.70 to recieve your new price :)

$7.70*0.3=2.31\\7.70-2.31=5.39$

Hope this Helps!

The graph of y =(x-3)^2 is shifted left 4 units and down 2 units. What is the axis of

Naddik [55]

Answer:

x = -1

Step-by-step explanation:

The axis of symmetry of the graph $y=(x-3)^2$ is x=3 but,

If shift the graph 4 units to the left it would mean the new value of x would be -1 as shown here:

$x=3-4\\x=-1$

-4 because it shifted 4 units to the left so the axis of symmetry of the transformed graph would be x = -1 and since it shifted 2 units down the y-coordinate of the turning point would be -2 so the turning point of the original graph is (3 , 0) and the turning point of the transformed graph is

(-1 , -2) I attached an image so you can visualize clearly

Losing 30% of its value is the same as saying it is now worth 70% of its original value. To find 70% of 50,000 you can do 50,000 x 0.7. The answer will be the new value of the car after one year. After two years you are essentially finding 70% of the new value which is 70% of the original. More simply, it is 50,000 x 0.7 x 0.7. An equation for this (and the answer to 1b) is 50,000 x 0.7^t where t is the number of years.

1a (i) is $10500 (50,000 x 0.7^1)
(ii) is $2521.05 (50,000 x 0.7^5)
(iii) is $1412.38 (50,000 x 0.7^10)
1b 50,000x0.7^t
