Factor (x) into linear factors given that k is a zero of f(x)

Mathematics
1 answer:
Lady bird [3.3K]3 years ago
3 0

Answer:

Factored form (linear): (4x+3)(x-3)(x-5)

Step-by-step explanation:

Using long division and factoring, we can find the answer. Since the root/zero of <em>5 </em>is given already, we can change this into a factor of <em>(x - 5)</em><em> </em>as 5 is a root.

Step 1: Long division. Divide f(x) by (x-5)

Once you do long division, you should have left over (x-5)(4x²+9x-9)

Step 2: Factor the quadratic

Since you can't do gcf, you have to leave the 4x as a factor. Once you factor out the quadratic, you should get the answer:

(x-5)(4x+3)(x-3)

Step 3: Rearrange (Optional)

(4x+3)(x-3)(x-5)

Write an inequality for people younger than 8 get in for $45
Tema [17]

Answer:

8 ≤ $45

Step-by-step explanation:

Given:

People younger than 8 get in for $45.

Now we can assume that the cost given might be to enter in the garden or might be in fair or might be at museum or might be at a zoo which is $45 for people which are younger than 8.

Now we can say for people younger than 8 means people or children who are of 8 years or who are below 8 years or say less than 8 years.

Hence we can say people who are less than or equal to 8 get in for $45

So the inequality equation becomes.

8 ≤ $45

Anna has 3 3/4 cups of yogurt to make smoothies. Each smoothie uses 1/3 cup of yogurt. What is the maximum number of smoothies t
KiRa [710]
Turn 3 3/4 into an improper fraction, so it becomes 15/4. Then divide 15/4 by 1/3. Which would just be to multiple by the reciprocal, 15/4 times 3/1, to get 11 1/4, and since 1/4 is smaller than 1/3 the maximum number of smoothies is 11

34kurt

Answer:

The common ratio is -2

Next three terms are 18, -36, and 72

Step-by-step explanation:

The common ratio is -2 since each consecutive term is being multiplied by -2

The next three terms are -9(-2) = 18, 18(-2) = -36, and -36(-2) = 72
