you have to look at the temperature in the picture and look at how it slopes down and predict.
Answer:
Ok so I used an app called Cymath it helps with checking your work and it goes down step by step and I use it for these kind of problems....the last step (3) is your answer.
Step-by-step explanation:
I hope I helped! :)
The only error you made is on problem 3. Everything else is correct. Nice work.
-------------------------------------------------------
Here is how to solve problem 3
Plug x = 1 into the equation and solve for y
-3x + y = 1
-3*1 + y = 1 ... replace x with 1
-3 + y = 1
y - 3 = 1
y - 3 + 3 = 1 + 3 .... add 3 to both sides
y = 4
<h3>The answer is 4</h3>
-------------------------------------------------------
Verifying the answer:
Plug (x,y) = (1,4) into the equation. Both sides should be the same number after simplifying both sides.
-3x + y = 1
-3*1 + 4 = 1 ..... replace x with 1; replace y with 4
-3 + 4 = 1
1 = 1
The answer is confirmed.
If you were to graph -3x + y = 1, which is equivalent to y = 3x+1, you'll find that the point (1,4) is on this line.
Answer:
The digits in the tens place increase by one from each number to the next.
Step-by-step explanation:
When you count by tens, all the numbers end in zero. For example, if you are counting ,"ten, twenty, thirty, …," the numbers are
10
20
30
40
etc.
The digits in the tens place increase by 1 from each number to the next.
This is the same as in ordinary counting: 1, 2, 3, 4, …
That's the pattern.
Answer:
the other dimension is 4.2 inches
Step-by-step explanation:
The scale factor from 5 inches to 10.5 inches is ...
10.5/5 = 2.1
Then the other dimension is 2 inches times that scale factor:
2.1×(2 in) = 4.2 in
