B. This is clear because of using the intercepts method. You know it crosses at y = 3 and x = -7. You also know to shade over by testing a spot in the shaded area.
Answer:
A
Step-by-step explanation:
Notice: The literal factors are all the combinations of a and b where the sum of the exponents is 4: a4, a3b, a2b2, ab3, b4.
The degree of each term is 4.
The first term is actually a4b0, which is a4 · 1.
Thus to "expand" (a + b)5, we would anticipate the following terms, in which the sum of all the exponents is 5:
(a + b)5 = ? a5 + ? a4b + ? a3b2 + ? a2b3 + ? ab4 + ? b5
The question is, What are the coefficients?
They are called the binomial coefficients. In the expansion of
(a + b)4, the binomial coefficients are
1 4 6 4 1
Answer:
x = 3/4
Step-by-step explanation:
Step 1: Find possibilities.
- We know one possibility: 8x - 6 = 0. This is because 0 cannot be positive or negative.
Step 2: Solve possibility 1.
(Add 6 to both sides)
(Divide both sides by 8)
Therefore, x = 3/4.
