Answer:
y = x + 8
Step-by-step explanation:
It is y = 1/1x + 8, but we don't put the one if it's at the botton. So, y = 1x + 8, but, when a one is in front of the x, we don't put it either. The answer is
y = x + 8
The y-intercept is where the line "touches" the y-intercept, in this case, 8.
The slope is how many times you go up-down, and to side from point to pint, in this case 1/1.
Makes sense? If so, hope this helps!
Answer:
standard form: y = x² - 2x - 8
vertex form: y = (x − 1)² - 9
factorized form: y = (x + 2)(x - 4)
Step-by-step explanation:
From inspection of the graph:
- Axis of symmetry: x = 1
- Vertex = (1, -9)
- x-intercepts = (-2, 0) and (4, 0)
- y-intercept = (0, -8)
Standard quadratic form: y = ax² + b x + c
Vertex form of a quadratic equation: y = a(x − h)² + k
If a > 0 then the parabola opens upwards
If a < 0 then the parabola opens downwards
(h, k) is the vertex
c is the y-intercept
Inputting the vertex into the vertex form gives:
y = a(x − 1)² - 9
= a(x² - 2x + 1) - 9
= ax² - 2ax - 8
Using the x-intercepts to create a quadratic equation:
y = a(x + 2)(x - 4)
= a(x² - 2x - 8)
= ax² - 2ax - 8a
Comparing the y-intercepts:
-8 = -8a ⇒ a = 1
Therefore, y = x² - 2x - 8
Answer:
angle A=52
Step-by-step explanation:
The box plot is not symmetrical for either data set.
<h3>What is Quartile?</h3>
Quartiles divide the data values into four parts; the first quartile is the 25th percentile, the second quartile is the 50th percentile (also the median), and the third quartile is the 75th percentile.
Firstly, order the two data set from smallest to largest as shown in diagram below
The value of median, Q2 is the 5th value of both set
The value of Q1 and Q3 is the first and third quarter of the set
The range of data set one is 5-2=3 and of set two is 12-1=11
The interquartile range of set one is 5 - 2 = 3
The interquartile range of set two is 5 - 1.5 = 3.5
Thus, the box plot is not symmetrical for either data set.

Hi there!
The answer is C. m
The name of a line is always a lower-case letter (e.g. m, k or any other letter from the alphabet).
