Screen printing a batch of shirts takes 0.4 minutes to make a shirt in addition to 4 minutes of initial set time. If it take 6.4

uranmaximum [27]

There are 6 shirts in the batch

Step-by-step explanation:

The given is:

1. Screen printing a batch of shirts takes 0.4 minutes to make a shirt

2. The initial set time is 4 minutes

3. It takes 6.4 minutes to screen-print a batch of shirts

We need to find how many shirts are in the batch

Let us represent these information in a function

Assume that there are n shirts in the batch

Then t(n) is the total time to screen-print n shirts in the batch

∵ There is initial set time = 4 minutes

∵ It takes 0.4 minutes to make a shirt

∵ The number of shirts = n

∴ t(n) = 0.4 n + 4

∵ It takes 6.4 minutes to screen-print a batch of shirts

∴ t(n) = 6.4

∵ t(n) = 0.4 n + 4

∴ 6.4 = 0.4 n + 4

- Subtract 4 from both sides

∴ 2.4 = 0.4 n

- Divide both sides by 0.4

∴ n = 6

There are 6 shirts in the batch

Can someone help me plzzz

-3x+2y=9
First you have to find the slope which you would do by labeling your coordinates So -5 is X1 and 3 is X2 and -3 is Y1 and -3 and Y2 is -6. This will help with finding the slope of you equation. So the set up would be Y2-Y1/X2-X1 so the equation would be -6- -3/ 3-5 which would give you 3/2. Then you take one of the coordinate points and your slope in a slope intecpet equation. So -3=3/2(-5)+b then solve. Which would be 9/2 then put you slope and b into a slope intercept equation so y= 3/2x+9/2 then to get it into Standard form you need to move your ex to the other side of the equation so -3/2x+y=9/2 in this equation can be simplified by multiplying two to each side so (2)3/2x+y=9/2(2) which would equal to 3x+2y=9

Which of the following sets of ordered pairs is not a direct variation?

Alecsey [184]

Answer:

(0, 0); (1, 3); (2, 4)

Step-by-step explanation:

The above-listed points are not on a line with constant slope, so do not represent direct variation.
