Mathematics
1 answer:
babymother [125]3 years ago
8 0

Answer:

y = 11

Step-by-step explanation:

y = 2x + 3

so 2x is (2 multiplied by x)

so if x is 4, and we have 2x, we would do 2 x 4

2x4 is 8.

take the 3 from before and add that to 8

8+3 is 11.

so y = 11

What is the image of (-9,0) after a reflection over the line y=x
SpyIntel [72]

Answer:

(0,-9)

Step-by-step explanation:

The image of a point (x,y) over a line y=x is given by the co-ordinate rule:

(x,y) → (y,x)

So, when we reflect a point over the line y=x, the x co-ordinate and y co-ordinate change their places.

Here, (x,y) is (-9,0). So, from the above rule, after reflection over the line y=x, the image has the following co-ordinates:

(0,-9)

Dave buys a baseball for $15 plus an 8% tax. Mel buys a football for $20 plus an 8$ tax. How much did each person pay?
-Dominant- [34]
Dave pays $15 and tax is $1.2 so dave spent a total of $16.20.

Mel pays $20 and tax is $1.6 so Mel spent a total of $21.60.

All you need to do is convert the percent to a decimal, so take 8 and divide by 100 and you get 0.08. then you need to  multiply the cost by the tax so 15*0.08=1.2 then you just add tax to original amount 15+1.2=16.2
