Answer:

D: 2y = 8x - 10  

Step-by-step explanation:

A:  y = 4x + 5. This has a slope of -4 Yes it could work.

B:  y = 4x - 5. No It does not work

C: 2y = 8x - 10. The slope is 8/2 = 4. So No it could not work.

<u>D: -2y = 8x - 10. The slope is 8/-2 = -4. Yes This Does work!  :)</u>

Is relation t a function? Is the inverse of relation t a function?
bonufazy [111]

<u>Answer:</u>

Hence, Relation t is a function. The inverse of relation t is a function.


<u>Step-by-step explanation:</u>

We are given the relation as:


x:    0 , 2 , 4 , 6


y:   -10 , -1 , 4 , 8

<em>Clearly from the y-values corresponding to the x-values we could see that each x has a single image (single y-value).</em>

Hence, the corresponding relation is a function.

Now we have to find whether the inverse of this relation is a function or not.

When we take the inverse of this function that is the y-values will behave as a pre-image and x-values as its image.

Hence we will see that corresponding to each y-value there is a unique image hence the inverse relation is also a function.

Hence, Relation t is a function. The inverse of relation t is a function.

Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner.explain
GarryVolchara [31]
Okay, so:

You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.

So,

423*.1

(you have to turn the percentage into a decimal; 10%= .10


423*.1= 42.3

So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.

I hope this helps!
