A desk is on sale for 34% off. The sale price is $363 .What is the regular price? I tried this problem so many times but I keep getting it wrong.. :(
Answers
Answer:
The answer to this is $550 for regular price. You take 100% -34% = 66% left. 363/66= 5.5 times 100 = 550

y=mx+b
m=slope
b=y intercept or where the line will go though the y axis
treat the equal to or greater than sign as equals for now
5x-y=5
subtract y from both sides
5x=5+y
subtract 5
5x-5=y
put the sign back in
5x-5 ≥ y
reverse
y ≤ 5x-5
one way is to subsitute values and get values out so
if x=1 then
y≤5(1)-5
y≤0
(x,y)
(1,0)
(2,5)
(3,10)
(4,15)
(0,-5)
plot the points
then the ≤ sign
since ther is an underline, that means that the points are included so draw a solid line through the points
then figure out which side to shade on
the easy way is, is the point (0,0) a solution?
subsitute
0 ≤ 5(0)-5
0 ≤ -5
false so we shade the section that does not include the point (0,0) in it
the graph would look like this attachment
5x - y ≥ 5 (subract 5x from each side)
-y ≥ -5x + 5 (divide - or -1 from each side) Note: when you are dividing or multiplying anything negative the sign changes
y ≤ 5x - 5 <--- answer
As for graphing you take the equation and graph it normally, but with a slight change. since y is less than or equal to 5x - 5, you have to color on the spACE BELOW the graphed line.

Answer:
The equation for the circle 12 seconds after the anchor is dropped is x^2 + y^2 = 360,000
Step-by-step explanation:
To find the equation for the circle 12 seconds when the radius of the ripple increases at a rate of 50 cm/s, the circle radius will be;
50 * 12 = 600 cm
Then place the equation inform of Pythagoras equation which is;
x^2 + y^2 = r^2
Where r is the radius
x^2 + y^2 = 600^2
x^2 + y^2 = 360,000
Then, the equation for the circle 12 seconds after the anchor is dropped is x^2 + y^2 = 360,000

means that when you subsituted g(x) for x in g(x), you got 16x-15
a(ax+b)+b=16x-15
distribute
xa^2+ab+b=16x-15d
we look at the x terms
therefor
xa^2=16x
a^2=16
a=-4 or 4
we will find out
look a constant terms
ab+b=-15
undistribute b
b(a+1)=-15
if a is -4 then
b(-4+1)=-15
b(-3)=-15
b=5
if a=4 then
b(4+1)=-15
b(5)=-15
b=-3
so
g(x)=-4x+5 or
g(x)=4x-3
if a=-4, b=5
if a=4, b=-3
