Subtract
$72 - $60 = $12
$12 profit
You then put the profit increase OVER the original price, making it a fraction. 12/60 now if you simplify this it is 1/5.
1/5 into a decimal is .20 and .20 to percentage is .20 x 100 = 20%
You can turn fractions to a decimal by diving the numerator by denominator. Just think of the line as the word DIVIDE.
Answer: 20% increase
Answer:
y = 3/2x - 5
Step-by-step explanation:
y = 3/2x + b
1 = 3/2(4) + b
1 = 6 + b
-5 = b
When you say degree, do you mean answer if so, there is no solution to this equation.
Its the first p< -8 or P>5
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -8 ± √((8)^2 - 4(2)(3)) ] / ( 2(2) )
x = [-8 ± √(64 - (24) ) ] / ( 4 )
x = [-8 ± √(40) ] / ( 4)
x = [-8 ± 2*sqrt(10) ] / ( 4 )
x = -2 ± sqrt(10)/2
The answers are -2 + sqrt(10)/2 and -2 - sqrt(10)/2.
