On a certain hot summer's day, 399 people used the public swimming pool. The daily prices are $1.25 for children and $2.50 for adults. The receipts for admission totaled $601.25. How many children and how many adults swam at the public pool that day?
Answers
Answer:
children: 317
adults: 82
Step-by-step explanation:
x = children
y = adults
x + y = 399
125x + 250y = 60125
125x + 125y = 49875
125x + 250y = 60125
-125y = -10250
y = 82
x + y = 399
x + 82 = 399
x = 317
Answer:
82 adults 317 children
Step-by-step explanation:
c= children
a = adults
A) a+ c = 399
B) 1.25(c) + 2.50(a) = 601.25
Multiply the whole A) by -1.25
Add A) +B) (c will be eliminated since 1.25c -1.25c=0)
-1.25 c - 1.25a = -498.74
1.25 c+ 2.50 a = 601.25
1.25 a = 102.50
Divide both sides by 1.25:
a = 82 (82 adults)
399-82 = 317 (317 children)
317 ($1.25) = $396.25 Price for 317 children
82($2.50) = $205 Price for 82 adults
Total:
$ 396.25 + $205 = $ 601.25
317 + 82 = 399

The slope of the line that contains the points (1, -1) and (2, 3) is 4. What is the y-intercept?
Answers
y-y1=m(x-x1)
y-(-1)=4(x-1)
y+1=4(x-1)
y+1=4x-4
y=4x-4-1
y=4x-5

-1-4=b
-5=b. Y-intercept is -5
The y-intercept of the line is -5.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
We can use the slope-intercept form of a linear equation to find the
the y-intercept of the line.
The slope-intercept form of a linear equation is:
y = mx + b
where m is the slope of the line, and b is the y-intercept.
We are given the slope of the line that contains the points (1, -1) and
(2, 3) is 4.
Therefore, we can substitute m = 4 and one of the points into the equation, and solve for b.
Let's use the point (1, -1):
y = mx + b
-1 = 4(1) + b
-1 = 4 + b
b = -1 - 4
b = -5
The y-intercept of the line is -5.
The equation of the line in slope-intercept form is:
y = 4x - 5
Thus,
The y-intercept of the line is -5.
