If all were children, revenue would be 700*$7 = $4900. Revenue is actually $6400 -4900 = $1500 more than that. Each adult admission that replaces a child's admission adds $10 -7 = $3 to the revenue, so there must have been
$1500/$3 = 500 . . . . adult admissions
There were 200 children at the show.
There were 500 adults at ths show.
Answer:
Slope= 30
Step-by-step explanation:
What does the slope tell me?
It tells me that every time I try to find the slope with different points I get 30 for slope.
Answer:
y = 7x
y = 2x -3
y = 3
x = -2
Step-by-step explanation:
- <em>Slope-intercept form: y= mx+b</em>
- <em>Parallel lines have same slope</em>
a)Parallel to y=7x+2 through the point (0,0)
<u>
This line will have a form:</u>
<u>Considering the given point of (0,0), to find the value of b:</u>
<u>The line is: </u>
b)Slope of 2 through the point (0,−3)
<u>
Solving as above:</u>
- y= 2x + b
- -3 = 2*0 + b ⇒ b = -3
- y = 2x -3
c)A horizontal line through the point (0,3)
<u>
A horizontal line will have constant value for y for any value of x:</u>
d)A vertical line through the point (−2,0)
<u>A vertical line will have constant value of x for any value of y:</u>
Answer:
yeah i dont know this one i tried to do it but i came up with a crazy answer
Let f(b) = <span>3b^2+13b+4/b+4
</span>the domain of f is D = {b/ b+4#0} so b# - 4
so the undefined value of is when b = -4
