Answer:
there are 150 children
Step-by-step explanation:
"there are 9 infants and 12 toddlers"
The number of children in the infant and toddler classes combined is 9 + 12 = 21.
21 children represent 14% of the total number of children in the day care program.
You are looking for the total number of children. The total number of children is 100% of the children.
Proportion:
Let x be the total number of children in the day care program.
21 children is to 14% as x children is to 100%
21/14 = x/100
Reduce the fraction on the left side.
3/2 = x/100
Cross multiply:
2x = 3 * 100
2x = 300
x = 150
Answer: there are 150 children
Answer:
See below.
Step-by-step explanation:
x^2 - 6x + 1 = 0
x^2 - 6x = -1
We halve the coefficient of x (which is -6/2 = -3) and square it, then add this to both sides:-
x^2 - 6x + (-3)^2 = -1 + (-3)^2
x^2 - 6x + 9 = -1 + 9
(x - 3)^2 = 8
x - 3 = ±√8
x = 3 ± √8
= 0.17, 5.83 to 2 decimal places.
Answer:
The equation of the line is
Step-by-step explanation:
Step 1
Find the slope of the given line
we have
Isolate the variable y
The slope of the given line is
Step 2
Find the slope of the line that is parallel to the given line
we know that
if two lines are parallel, then their slopes are the same
so
----> slope of the given line
----> slope of the line parallel to the given line
Step 3
Find the equation of the line parallel to the given line that passes through the point
we know that
the equation of the line in slope-intercept form is equal to
where
m is the slope of the line
b is the y-intercept (value of y when the value of x is equal to zero)
In this problem we have
-------> this is the y-intercept
so
substitute
the equation of the line is
