A) The amount of change is .20 (20 cents) so we need to find what percent of $4.00 is .20...
4 * x = .20
x = .20/4 = .05
Multiply by 100 (move decimal 2 places to the right) to change decimal to percent.
.05 = 5% increase
b)The increase is .75. What percent of 3.00 is .75
3 * x = .75
x = .75/3
x = .25 x 100 = 25% increase
c) The amount of change is .75 but this time we are going from 3.75 to 3.00 so we find out what percent .75 is of 3.75.
3.75 * x = .75
x = .75/3.75
x = .20 x 100 = 20% decrease
19/1634
Answer = 86
To get this, simply align the paper by putting 19 on the outside of the division box and 1,634 on the inside of the division box, then, decipher whether 19 can go into 16 (It cannot), so, you would have to divide 19 into the number 163. After doing this, put the sum of 19 divided by 163 on top of the division box and divide 40 into 19. After adding the sum on top the the division box to sum of 40 divided by 19, you should get your final answer, which is of course, 86.
Also, you can simply look up a tutorial on Google or YouTube!
Hope I've Helped! :)

Answer:
y = –|x - 1| + 3
Step-by-step explanation:
The "vertex" is (1 , 3)
y = –|x - 1| + 3
Answer:
550a + 590b = 1275
Step-by-step explanation:
We use the following relation to solve this question:
In which v is the velocity, d is the distance and t is the speed.
In this question, we find the distance, so we use:
A plane is flying to Metro City. The plane started its journey 1275 miles from Metro City.
This means that 
.
Write an equation in standard form to represent the situation if the plane travels a hours at 550 mph and b hours at 590 mph.
This means that 
.
Which equation is correctly written in standard form to represent this scenario?
1275 = 550a + 590b
550a + 590b = 1275
