Answer:
i think is probably 70 sec or 75
Step-by-step explanation: idk
Missing details:
Write an addition expression for the temperature relative to when Iko woke up.
Answer:
![T = x -3](https://tex.z-dn.net/?f=T%20%3D%20x%20-3)
Step-by-step explanation:
Let the temperature when he woke up be x
When he woke up, it rises to 11 degrees.
This is represented as:
![t_1 = 11](https://tex.z-dn.net/?f=t_1%20%3D%2011)
At bedtime, it dropped by 14 degrees.
This gives
![\triangle t = 11 - 14](https://tex.z-dn.net/?f=%5Ctriangle%20t%20%3D%2011%20-%2014)
![\triangle t = -3](https://tex.z-dn.net/?f=%5Ctriangle%20t%20%3D%20-3)
The relative change T is:
![T =Initial\ Temp + Change](https://tex.z-dn.net/?f=T%20%3DInitial%5C%20Temp%20%2B%20Change)
![T = x + \triangle t](https://tex.z-dn.net/?f=T%20%3D%20x%20%2B%20%5Ctriangle%20t)
![T = x -3](https://tex.z-dn.net/?f=T%20%3D%20x%20-3)
Answer:
slope=0
Step-by-step explanation:
Hi there!
We're given a graph with a line and two marked points on the graph: (-1,3) and (3,3)
the formula given for slope calculated from two points is (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are points
we have our two points: (-1,3) and (3,3) and we can label them:
x1=-1
y1=3
x2=3
y2=3
now substitute into the formula
note: Remember the formula shows SUBTRACTION, even though we have NEGATIVE numbers. When we simplify, we'll add the numbers.
slope=(3-3)/(3--1)
simplify
slope=0/4
divide
slope=0
Hope this helps!
Answer:
it is C
Step-by-step explanation:
8-3=5
5-3=2
2-3=-1
<u>-1-3=-4</u>
Factor: 27x^2y - 43xy^2
Factors of 27:
1(27), 3(9)
Factors of 43:
1(43) no common number between these two.
Factor x, and y, as they present, therefore, the numbers cannot be factored. stay as is.
Your answer is: xy(27x - 43y)
Hope that helps!!!
