It is very simple you minus 9 from 7. 9-7=2. So Alberto's birthday is on the 2nd.

The function f(x) = 1.50x – 30 gives the amount of money Amelia has to spend each week for x school lunches, after taking money

Naya [18.7K]

To find the inverse, switch the x and y, and then solve for y (f(x) is the same as y)

So we get:
x=1.50y-30 (add 30 to both sides)
x+30=1.50y (divide both sides by 1.5)
x/1.5+30/1.5=y
y=x/1.5+20

Hope this helps

A taxi journey of 30km cost $3,600.At the same rate per kilometer .A what would be the cost of travelling 25k.B.How far could yo

madreJ [45]

Answer:

The cost of traveling 25km would be $3000.

You can travel 35 km for $4200.

Step-by-step explanation:

Consider the provided information.

For 30km cost $3,600.

30 km = $3600

Divide both sides by 30.

$\frac{30}{30}\text{ km}=\frac{3600}{30}$

$1 \text{ km} =120$ ....(1)

The cost of 1 km is $120.

Part (A) what would be the cost of traveling 25km

Multiply both the sides of equation 1 by 25.

25 km = 3000

Hence, the cost of traveling 25km would be $3000.

Part(B) How far could you travel for $4,200?

Divide 4200 by 120.

$\frac{4200}{120}=35$

Hence, you can travel 35 km for $4200.

The midpoint of a line segment is (-1, 4). The endpoints of the line segment are (3, y) and (-5, 10). What is the value of y?

viktelen [127]

Answer:

-2

Step-by-step explanation:

The midpoint is the average of the end point coordinates, so ...

4 = (y +10)/2 . . . . the y-coordinate is the average of the y-coordinates

8 = y +10 . . . . . . . multiply by 2

-2 = y . . . . . . . . . . subtract 10
