Answer:
The solution set is (-3, 4).
Step-by-step explanation:
x2 + 4x - 9 = 5x + 3
x^2 + 4x - 5x - 9 - 3 = 0
x^2 -x - 12 = 0
(x - 4)(x + 3) = 0
x = -3, 4.
Answer:
-14°F
Step-by-step explanation:
First, we start at 12°f. Then, the temperature changes by -26°f. This means that we add (-26°f) to what we currently have. We then have
12 + (-26)
= 12-26
= -14°F
Answer:
3
Step-by-step explanation:
1 yard is three feet
Answer: 90degrees
Step-by-step explanation: The question was asked in degree. So the answer should be in degree. Which leaves us with no option than 90degrees.
The magnitude of a vector has to do with the vector length that is used to show the initial and final position of the vector.
<h3>What is a Vector?</h3>
This refers to the quantity that has a magnitude and direction and can be used to show position.
Hence, we can see that the vector, magnitude, and the directional angle values are not given so a general overview was given.
