Answer:
y = 392x + 6350
Step-by-step explanation:
Here, we calculate the average rate of change in the number of muffins sold between the two years
Mathematically that will be the difference in number of muffins divided by the number of years
We have this as;
(8310-6350)/(2015-2010)
= 392
an average of 392 muffins were sold in a year
The general form of the equation of a straight line is;
y = mx + c
we have m as 392
so;
y = 392x + c
To get c, we make a substitution
2015 is 5 years after 2010, so x will be 5 and y will still be 8310
so;
8310 = 392(5) + c
c = 8310 - 2960
c = 6350
So the equation is;
y = 392x + 6350
Answer:
What percent of the school are girls? 55%
What percent of the school are boys? 45%
How many boys are there? 162
How many girls are there? 198
Step-by-step explanation:
The number of girls = 198
The percent of girls = 198/360 x 100% = 55%
The number of boys = 360-198 = 162.
The percent of boys = 162/360 x 100% = 45%.
Answer:
Yes.
Step-by-step explanation:
Just like normal algebra, you factor our the common factor, in this case, 5.
Thus,
