Answer: option c. She subtracted the coefficients instead of dividing them
Explanation:
1) Starting expression (given):
2) Simplified expression (given)
3) Note that if you do the operations correctly you get:
i) By dividing the coefficients:
ii) By subtracting the exponents
And that is the correct result.
4) But if you subtract the coefficients, instead of dividing them, then you get 10 - ( - 5) = 10 + 5 = 15
Which is what she obtained in the numerator. And this is wrong, because the coefficients must be divided.
It is the exponents what you subtract, as per the rule of quotient of powers.
Answer:
y=1/5x+5
Step-by-step explanation:
Slope-intercept form is written y=mx+b.
y- needs to be by itself in this form.
m- the slope.
x- always to the right side of the slope, or m.
b- y-intercept.
Now that we know this, all we have to do is plug in the numbers we have. So when we plug this in, the equation looks like this:
y=1/5x+5
Hope this helps you and have a great day :3
Answer:
The population grew by 12600 people.
Step-by-step explanation:
In 2010, the population of a city was 180,000. From 2010 to 2015, the population grew by 7%. From 2015 to 2020, it fell by 6%. How much did the population grow from 2010 to 2015, to the nearest 100 people?

Answer:
A die is thrown which means that it can land on either 1-6 on the die.So if you want to find the probability of the multiple of 2 or 3....we have multiplies of 2 in the die from 1-6 which is 2,4 and 6 if you count them they are just 3 numbers and since there is a probability of it to land on any of them it will be 3/6 which is 1/2 if yiu divide by 3 to it's lowest term....Then multiple of 3 is 3,and 6.which will be 2/6 which is 1/3 if u cut to its lowest term. Or in the question means addition sign in probability then it is 2 or 3 which is (1/2)+(1/3)=5/6.Thank you for the question
