Zero of the functions f(x)= x^2 + 4x+3 and why ?

1 answer:

6 0

There are two zeros: -3 and -1. This is because when you factor f(x)<span>= x^2 + 4x + 3, it becomes f(x) = (x + 3)(x + 1). In order to find the zeros, set f(x) to 0, and then solve for x for both (x + 3) and (x + 1). You can check your answer by substituting either -3 or -1 for x in the equation 0 = </span>x^2 + 4x + 3.

The coordinates of the vertices of AJKL are J(-5, -1), K(0, 1), and L(2, -5).

We need slope of all lines ?

J(-5,-1)
K(0,1)
L(2,-5)

Slope of JK:-

$\\ \sf\longmapsto m=\dfrac{1+1}{0+5}=\dfrac{2}{5}$

Slope of KL:-

$\\ \sf\longmapsto m=\dfrac{-5-1}{2-0}=\dfrac{-6}{0}=-3$

Slope of JL

$\\ \sf\longmapsto m=\dfrac{-5-1}{2+5}=\dfrac{-6}{7}$

Which should come next at the end of this series of numbers: 1, 2, 0, 3, -1?

Vinil7 [7]

The next number would be 4 because you add 1, then, subtract 2, add 3, subtract 4, meaning you would add 5 to -1 and get 4
The answer is 4

PLEASE ANSWER, FIRST WILL GET A BRAINLIEST, + 2 THANKS (Teaser) An angle that measures 6° is drawn on a piece of paper. You are

Tomtit [17]

Answer: same. ( 6 degree )

Step-by-step explanation:

According to the question, An angle that measures 6° is drawn on a piece of paper. As you are looking at the angle through a×6 magnifying glass, which means it magnifies by a factor of 6 indeed. The length and the width of the shape may magnify by factor of 6, but the degree measure of the angle will remain the same.

Even if it is magnified by a factor of 100, the measure of the angle you see on the paper when you look through the magnifying glass will remain the same.
