<span>Hi there,
A line that touches a curve at a point without crossing over. Formally, it is a line which intersects a differentiable curve at a point where the slope of the curve equals the slope of the line. Note: A line tangent to a circle is perpendicular to the radius to the point of tangency.</span>

Child's ticket x=y-5.75
Adult would be found by solving for y.
x=y-5.75
5.75+x=y-5.75+5.75
5.75+x=y
Y=x+5.75
Let's first start off with an equation to represent Celeste's budget:

Where:
'h' is the money in dollars that she needs to get her hair cut
'p' is the money in dollars that she needs to get her hair permed
'l' is the money in dollars that she needs for lunch
Now let's simplify this equation using the information that was given:

*This must be true since it is told that she needs $5 for lunch

*This is because the perm costs twice as much as the hair cut
Our new/updated equation is:

This is much easier to solve, let's rearrange and solve for 'p':



Therefore the perm costs $36
I hope this helps! Let me know if you have any further questions.
Answer:
D. 7
Step-by-step explanation:
to find the median the equation is to write out all the numbers given in order from least to greatest.
4, 4, 6, 6, 7, 7, 9, 9, 10
now cross off 1 number from each side. and keep doing thaf until you find the median, aka the middle number.
4, 6, 6, 7, 7, 9, 9
cross off the first and last number that remains.
6, 6, 7, 7, 9
again until 1 number remains **that number left will be the median**
6, 7, 7
cross off first and last.
7
7 will be the median.
I hope this helps!! if you need more explanation let me know and I will supply more information.
thank you
