634, you have to multiply it by 89% of the original number, 712, to deduct 11%
In a quadratic equation , we use the quadratic formula to find the solutions x = (-b ± √(b2 - 4ac)) / 2a where a, b, and c are coefficients of the equation ax2 + bx + c = 0 Since x=6 is the only x-intercept, the equation would be (x - 6)(x - 6) = 0 Expanding this out, we get x2 - 12x + 36 = 0 In this equation, a = 1b = -12c = 36 Now the discriminant is the square-root part of the formula: b2 - 4ac Now plug in the values of a,b, and c into the discriminant. (-12)2 - 4(1)(36) = 144 - 144 = 0 This number is under the square-root. The square-root of 0 is 0. Your answer is (A).
(I had the same question in math last week)
Answer:
-2.4 + 3.2t
Step-by-step explanation:
To combine the like terms, add both the numbers with the variable t together and the others without together.
-3.6+1.2= -2.4
-1.9t + 5.1t = 3.2t
Putting the sums together you should get:
-2.4 + 3.2t
If you're confused about how to subtract/add negative numbers, I like to ignore the sign--depending on what it is of course. For example, I rewrite -3.6+1.2 as 3.6-1.2. When you get the answer for that (2.4), add a negative symbol in front because the negative number was greater than the positive. I hope that helps rather than confusing you.
It is equal to 0..... it is
Step-by-step explanation:
yes
About 31%
You add all of the numbers up to find out how many cans there are overall. Then take 80(cans of tuna) / overall cans and get around 31%.
