Which algebraic expression represents a number divided by 2?
Answer: x/2
Step-by-step explanation:
A unknown number can be represented by a variable (‘x’ in this case) and the unknown number (x) is being divided by 2, therefore its x/2
Find the equation in slope-intercept form that passes through the points (9, 3) and (19, -17).
Answer:
y=-2x+21
Step-by-step explanation:
use y2-y1/x2-x1 to find the slope so= -17-3/19-9=-20/10=-2
so once you find the slope take one of the points and plug it into the slope-int equation so... if you take (9,3) and take your slope (-2) so it would be: 3=-2(9)+b solve for b to get 21=b as your int. so.. y=-2x+21
. The units sold follows the equation U = 10000 – 2000P. The money from sales is equal to the units sold times the price P of the unit. Write an equation for sales as a function of price.
Given:
The units sold follows the equation
[tex]U = 10000-2000P[/tex]
To find:
An equation for sales as a function of price.
Solution:
Let S represents the sales function.
We know that, the money from sales is equal to the units sold times the price P of the unit.
[tex]S=U\times P[/tex]
[tex]S=(10000-2000P)\times P[/tex]
Using distributive property, we get
[tex]S=10000P-2000P^2[/tex]
Therefore, the equation for sales as a function of price is [tex]S=10000P-2000P^2[/tex].
what changes in a wave to make a sound high pitch or low pitch?
Answer:
Volume is dependent on how hard the air is pushed through. Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.

A car travels 360 miles in 8 hours (with a constant speed). How much time will it take traveling 168 miles?
Answer:
3.7hours
Step-by-step explanation:
Step one:
A car travels 360 miles in 8 hours
the speed is calculated as
speed= distance/time
speed= 360/8
speed= 45mph
Step two:
How much time will it take traveling 168 miles?
having found the speed, which is the rate at which the car is tavelling
time= distance/speed
time= 168/45
time= 3.7hours

Complete the latter: 1, 5, 9, 13.
Answer:
17
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
The answer is 17 because We noticed that 5 is 4 more than 1, 9 is 4 more than 5, and 13 is 4 more than 9. They are all a +4 pattern so you just simply add 4 to 13 which is 13 + 4 + 17 So our answer is 17

On a test that has a normal distribution, a score of 41 falls three standard deviations below the mean, and a score of 73 falls one standard deviation above the mean. Determine the mean of this test.
Answer:
The mean of the test is 65
Step-by-step explanation:
Let the mean be x and SD be y
3 SD BELOW the mean means that we are taking away 3 SD FROM the mean
Mathematically, we have that as;
x - 3y = 41 •••••(i)
73 is 1 SD above mean
Mathematically;
x + y = 73 ••••••••(ii)
So let us solve both equations simultaneously
Simply multiply equation ii by 3 then add to i
x - 3y = 41
3x + 3y =219
4x = 41 + 219
4x = 260
x = 260/4
x = 65
