Junior already has 300. So he needs ? to get to 100,000.

100,000 - 300= 99,700.

You can add 99,700 + 300 just to be sure and you will get 100,000 so...

The answer is he needs 99,700 pins.

The graph relates the distance traveled by Train A, in miles, and the time taken, in hours. The table shows the distance travele
melomori [17]

Answer:A)

Yes, the relationship is proportional.

B)

66,000 miles.

Step-by-step explanation:

A)

Yes, the graph represents a proportional relationship.

Since, A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:  

y=kx

for some constant k , called the constant of proportionality .

As y=12000x hence the relationship is proportional.

B)

We calculate the equation of the graph with the help of two points on the graph namely (2,24000) and (4,48000) with the help of slope-intercept form of the line.

y=mx+c where m denotes the slope of the line and c denotes the y-intercept of the line.

Here when x=2 y=24000 and when x=4 y=48000

Hence, 24000=2x+c

and 48000=4x+c

on subtracting the above two equations we have:

m=12000 and c=0

Hence, the equation of line is y=12000x

Now the value at x=5.5 is:

y=12000×5.5=66,000

Hence, the number of miles the probe travels in 5.5. hours is 66,000 miles.

Anyway you can help me out?
Trava [24]
Okay, so to get the inverse function, you need to isolate the x first.

You can do this by multiplying by 4. Then, -2 to get just 3x and finally divide by 3 so that you just have x on its own. If we write this all out, we get (4x-2)/3.

Next, we need to substitute 24 into x's place. So, we have ((4x24)-2)/3. Then, we can just simplify. 4x24=96. 96-2=94. 94/3=32.6.

Hope this helps :)

What number would you multiply the 2nd equation by in order to eliminate the y terms?
leonid [27]

Answer:

x=3

y=-1

Step-by-step explanation:

first multiply the 2nd row by 2 so you will get

4x-4y=16

4x+2y=10

then subtract the 2nd row from the first row and so you will get

-6y=6

then solve for y in the above equation

y=-1

then substitute y=-1 into any 2 equations .

i picked the first 1

4x-4 × -1=16

then solve for x .

you will get

x=3
