Given:
Cost of printing a catalog: flat rate of $52 and $0.20 per copy.
C = 52 + 0.20x
C is the total cost of printing x number of copies.
x = 500
C = 52 + 0.20(500) = 52 + 100 = 152
x = 1000
C = 52 + 0.20(1000) = 52 + 200 = 252
x = 1500
C = 52 + 0.20(1500) = 52 + 300 = 352
x = 2000
C = 52 + 0.20(2000) = 52 + 400 = 452
x = 2500
C = 52 + 0.20(2500) = 52 + 500 = 552
I will give the answers, you can comment any questions! Glad to help you!!!

Set up a proportion
3 coins:8 notes and then the other one 24 coins : x (unknown notes)
they have a relationship so we can set them equal to each other.
3/8=24/x cross multiply: 8 * 24 = 192
Now divide that by 3: 192/3 = 64
So there are 64 notes in the bag
An equation for annealing soda-lime glass is y(t)=−14t+500 , where t is time in minutes and y is the temperature of the glass in ˚C.
To find the y intercept , we plug in 0 for t
y intercept is the value , where time is 0 minutes
so we plug in 0 for t and find out y(0)
y(t)=−14t+500
y(0)=−14(0)+500 = 500
When t=0 , the value of y = 500
So , y intercept is (0,500)
Answer:
x = ± 2i
Step-by-step explanation:
The equation has no real roots, gut has complex roots
Given
x² = - 4 ( take the square root of both sides )
x = ± 
= ± 
[ Note that 
= i ]
= ± 
× = ± 2i
