for m(x)=-2x+7, find the value of x for which m(x)=13
Answers
Answer:
x = -3
Step-by-step explanation:
m(x) = -2x + 7
13 = -2x + 7
6 = -2x
x = -3
The explanation if you need it is since m(x)=13 we get the equation 13=-2x+7. Then we use the equation to find x.
13= -2x+7
-7 -7
6= -2x
— —
-2 -2
-3=x
You then want to check your answer by substituting -3 for x
13= -2(-3) +7
13= 6+7
13=13
If your answers match then your answer is correct

John is performing an experiment in which a solution alternates between a clear color and a bluish-purple color at a regular time interval. He observes that the time interval between color changes is 30 seconds (s). Sally replicates the experiment with the same solution, but at a temperature that is 10 degrees Celsius (°C) higher. What is the most likely time interval between color changes at this higher temperature?
Answers
Answer:
15 seconds
Step-by-step explanation:
The given parameters for the experiment are;
The time it takes the solution to change from a clear color to a bluish-purple color at a given temperature = 30 seconds
The temperature at which Sally replicates the experiment with the same solution = 10°C higher than the temperature the experiment was carried out by John
Given that the process involves a change in color, which is a characteristic of a chemical reaction, and that the rate of a chemical reaction increases as the temperature of the reacting system is increased, we have time it takes for the solution to change color at a temperature increased by 10°C, will be a time lesser than 30 seconds

Which of the following
represents a function?
PLEASE HELP 15 POINTS OR BRAINLIEST JUST ASK PLEASE HELP ME
Answers
Answer:
A: represents a function
Explanation:
Every other option, A, has two y for one x.
It can be a function if there is 1x for 1y.
If this was helpful, please mark brainliest. Have a beautiful day!
Choice A is not a function because x = 2 leads to more than one y value (y = 1 and y = 7 at the same time)
Choice B is not a function for similar reasoning. Here we have x = 1 lead to y = 2 and y = 5 simultaneously.
Choice D is also not a function because of the two points (5,2) and (5,4). This tells us we have x = 5 lead to y = 2 and y = 4 at the same time.
A function is only possible if you have any input lead to exactly one output. Choice C shows this. Note how it passes the vertical line test. It is impossible to draw a vertical line through more than two points on the function curve.
The momentum of an object, p, is determined by its mass, m, and its velocity, v. The formula for this relationship is shown.

1101101+11011 in binary numbers please help
Answers
Answer:
The answer is 1000 1000
Step-by-step explanation:
In HEX, it would be 88.
In DEC, it would be 136.
In Oct, it would be 210.
Binary, how to add numbers together.
1101101
+ 11011
10001000
This is just like adding regular numbers together.
For example, when you add 88 to 55, this is what will happen
1(r)
88
+ 55
13(+1) 3
143
With binary, when 1 and 0 are added together, the result is 1. When 1 and 1 are added together, the result is 1 and 0 (1 being the "remainder", or the number that is carried over. This number is then added to the next part of the number when adding, just like in normal addition.

what two numbers multiply to -36 and add up to 5
Answers
Answer:
9 and -4
Step-by-step explanation:
Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.
First, test if they multiply to -36:
9(-4)
= -36
Then, check if they add up to 5:
9 + (-4)
= 5
So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5
