Although the terms might seem intimidating, this is a simple substitution problem.
X + Y = _______
Substitute the values of X and Y in terms of w
(7w^2 + 4w - 6) + (w^2 - 11w + 13) = ______
Now all you need to do is combine like terms (terms that have the same variables raised to the same power)
8w^2 - 7w + 7
Final Answer: 8w^2 - 7w + 7
Answer:
Step-by-step explanation:
1/4y - 1/2
= 1/4y x 4 : 4 - 1/2
= y/4 - 1/2
Answer:
It's false because it's actually about 75%.
Step-by-step explanation:
From 15-45 is 3/4 of the plot
Answer:
To find to polynomial from zeros.
Find the factors. If it is a positive zero, the factor will be (x- zero) If it is a negative zero if is (x+zero)
Multiply the factors together.
Zeros of -4, -2, 5 would be:
Find the factors: (x+4)(x+2)(x-5)
Multiply the factors together: Will start out with FOIL for (x+4)(x+2) = x2+2x+4x+8 Combine like terms. Then multiply by the last factor
(x2+6x+8)(x-5) using the distributive property
x3+6x2+8x-5x2-30x-40 Combine like terms
x3+x2-22x-40
For the next one, the factors are a bit more complicated because of the radical. With a radical, you will also have to have a factor with the conjugate (Same term opposite sign)
4, 6, negative square root of 7
Factors would be: (x-4)(x-6)(x-√7)(x+√7) You can FOIL the first 2 factors and the last 2, then multiply them together using the distributive property.
Step-by-step explanation:
