Please help me!!!!!!!! Factor z2 – 3z – 18
Vladimir [108]
First, the factor pairs for 18 are:
1, 18
2, 9
3, 6

Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3

Set each equal to 0;
z = -6
z + 6 = 0

z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.

The function f(x) is shown in this graph. The function g(x)=-2x-6. Compare the slopes
stich3 [128]

Since f(x) = -3x + 2, the slope of f(x) is greater than the slope of g(x).

Hence, the answer is (D).

Spin a spinner numbered 1 to 5 and toss a coin. What is the probability of spinning an odd number
Sphinxa [80]

Answer:

<u>The correct answer is B. 3/10.</u>

Step-by-step explanation:

1. Let's calculate the probability of spinning an odd number:

We can spin an odd number (1, 3 or 5) out of 5 events, it means that the probability of spinning an odd number is:

3/5

2. Let's calculate the probability of getting tails on the coin:

We can toss a coin and get tails one out of 2 events, it means that the probability of getting tails on the coin is:

1/2

3. These are independent events because the fact that we spin an odd number does not affect the probability of getting tails on the coin, thus:

Probability of spinning an odd number  and getting tails on the coin =

3/5 * 1/2 = 3/10

<u>The correct answer is B. 3/10</u>
