The temperature is 3 degrees less then it was at lunchtime when he went to bed you didn’t ask a question or explain it so I’m assuming this is what you meant
Answer:
(- 3, 2 )
Step-by-step explanation:
The vertex is at the point where the 2 lines meet V
The coordinates at this point is the vertex
vertex = (- 3, 2 )
X = how much Tim has
y = how much Tom has
x + y = 2.40
x = 3y
Substitute 3y for x
3y + y = 2.40
4y = 2.40
y = 0.60
Plug in y value into previous equation
x = 3(0.60)
x = 1.80
ANSWERS: Tim has $1.80 and Tom has $0.60
Step 1: Find the slope<span> of the </span>line<span>. To find the </span>slope<span> of the given </span>line<span> we need to get the </span>line<span> into </span>slope-intercept form<span> (</span>y<span> = mx + </span>b), which means we need to solve fory<span>: The </span>slope<span> of the </span>line<span> 3x – 5y = 9 is m = </span>3<span>/5. Therefore, the </span>slope<span> of the </span>line parallel<span> to this </span>line<span> would </span>have<span> to be m = </span>3<span>/5.
</span>

<u>Step-by-step explanation:</u></h3>
Given function to us is :-
And we , need to write the function a a product of linear factor by grouping or using the x method or a combination of both . So let's factorise this ,
I have also attached the graph of x²-9.
