Answer:
-6, -6
Step-by-step explanation:
Given :
Solving :
- This is of the form : <u>a² + 2ab + b²</u>
- Hence, the factored form is <u>y = (x + 6)²</u>
- y = (x + 6)(x + 6)
- x + 6 = 0 ⇒ x = -6
- x + 6 = 0 ⇒ x = -6
The zeros are : -6, -6
The company has 75-60=15 employees who do not have phones, that makes 15/75=0.2=20% who don't have a phone.
<h3>
Answer: A) None of the above</h3>
==================================================
Explanation:
Let's solve (x-2)(x-5) = 0 and doing so leads to x = 2 or x = 5. Plugging either value in for x makes the expression (x-2)(x-5) become 0.
Let's pick a value to the left of x = 2, let's say we pick x = 0. Plug this into the expression (x-2)(x-5) and we get the following:
(x-2)(x-5)
(0-2)(0-5)
(-2)(-5)
10
The result is a positive number, meaning that (x-2)(x-5) is positive when we select a value smaller than 2.
Now we'll repeat this with a value between 2 and 5. Let's say we pick on x = 3.
So,
(x-2)(x-5)
(3-2)(3-5)
(1)(-2)
-2
The result is negative, so (x-2)(x-5) is negative when 2 < x < 5. This immediately rules out choices C and E.
Unfortunately, answer choices B and D won't work either for similar reasoning. The only thing left is choice A.
Side note: The answer in interval notation is so basically it's everything but values between 2 and 5; however, x = 2 and x = 5 are part of the solution set.
Another side note: if you flip the inequality sign from to , then the answer would be choice C.
Answer:
Mia is right since the x-axis crosses the y-intercept and her line is an inequality.

The absolute error of the veterinarian's estimate is: 0.4 kg
The Percentage error the veterinarian's estimate is: 5.7%
<h3>What is Absolute Error and Percentage Error?</h3>
- Absolute error = |x0 - x|
- Percentage error = (|x0 - x|)/x0 × 100
- Where, x = actual value, and x0 = measured value
Given:
x = 7.4 kg
x0 = 7 kg
Absolute error = |7 - 7.4| = 0.4 kg
Percentage error = 0.4/7 × 100 = 5.7%
