Subtracting a negative number is like removing debt. When you remove debt, you effectively gave someone money and the value of their bank account increased.
Another answer is that “subtraction is addition of the opposite,” so subtracting a negative number is really adding a positive number, which again causes the other number to increase.
First: Figure out the cost per candy bar currently by dividing 3.22 and 14
3.22 / 14 = 0.23
Second: Add in 0.15 to your total to solve for the prior cost of the candy
0.23+0.15 = $0.38
Answer:-49.3a-1.62b+65.5
Step-by-step explanation:
Combine Like terms:
-13.5a-35.8a=-49.3a
-34.12b+32.5b=-1.62b
Answer: -49.3a-1.62b+65.5
Answer:
Step-by-step explanation:
At first you need to turn roots into factors and then multiply the
then you have
f(x) = a(x + 2)(x -5)^2
f(x) = a(x + 2)(x^2 - 10x + 25)
f(x) = a(x^3 - 8x^2 + 5x + 50)
You can use either synthetical or the factor
theorem
f(-2) = a(-8 - 8(4) + 5(-2) + 50) = a(0) = 0.. check, f
=-2
€(5) = a(125 - 8(25) + 5(5) + 50) = a(0) = 0 check, f
= 5 works
Then divide it to the the second multi
And you should get x^2 - 3x - 10 = (x - 5)(x + 2),
where the other two zeros are X =5 , and x=-2
