If the ratio of boys to girls is 11:9 and there are 124 more boys than girls:
Let's say that the number of boys is 11x and the number of girls is 9x.
So, 11x = 9x + 124
2x = 124
x = 62
The total number of students = Number of boys + number of girls
= 11x + 9x
= 20x
= 1240 students
Thus, the total number of students attending the school is 1240.
y = - \frac{2}{5} x - 2
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 5y = 10 into this form
subtract 2x from both sides
5y = - 2x + 10 ( divide all terms by 5 )
y = - \frac{2}{5} x + 2 ← point- slope form with slope m = - \frac{2}{5}
Parallel lines have equal slopes hence
y = - \frac{2}{5} x + c is the partial equation of the parallel line
to find c, substitute ( 5, - 4 ) into the partial equation
- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2
y = - \frac{2}{5} x - 2 ← equation of parallel line
In your question that first im confused but i arrange if correctly though, in my calculation the possible power of the series is infinity <span>∑ n-0 times the -1 one to the power of n over n+1 times x to the power of n+2</span>
224 i think because we are in the same class and i like boogers and poop
