how to graph:-8x-y=8
Answers
In order to graph this equation, we first need to find two ordered pairs that are solution to this equation.
To do this, we can choose a value for x and calculate the corresponding value of y.
Choosing x = 0 and x = -1, we have:
[tex]\begin{gathered} x=0\colon \\ -8\cdot0-y=8 \\ 0-y=8 \\ y=-8 \\ \\ x=-1\colon \\ -8\cdot(-1)-y=8 \\ 8-y=8 \\ y=0 \end{gathered}[/tex]Now, graphing the points (0, -8) and (-1, 0) and the line that passes through them, we have:
So the blue line represents the graph of the equation given.

Can someone please help I give lots of points...
Answers
Answer:
y=-x^2+16x-55
Step-by-step explanation:
Since two intercepts are given (the two x-intercepts in this case), we should probably use intercept form.
y=a(x-b)(x-c)
plug in the intercepts which are 5 and 11 in this case
y=a(x-5)(x-11)
to solve for a, use the remaining point and set x to 6 and y to 5. we can do this because (6,5) is given to us as a solution of one of the points on the graph.
5=a(6-5)(6-11)
5=a*(-5)
a=-1
so, the equation should be:
y= - (x-5)(x-11)
expand the parentheses to get:
y=-x^2+16x-55
(also 5 points isn't a lot of points...)

The measure of the angle b is 61°.
In Euclidean geometry, an angle is a shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. The plane that contains the rays contains the angles created by two beams.
Vertical Angles (Vertically Opposite Angles): The opposing angles created by the junction of two lines are known as vertical angles or vertically opposite angles. A pair of angles that are vertically opposed to one another are always equal.
The figure describes two angles 61° and b.
Now, from the figure the angles 61° and b are vertically opposite angles.
Therefore, the angles are equal.
b = 61°
Hence, the measure of angle b is 61°.

Write down equation of lines l and m
Answers
Step-by-step explanation:
I assume you need the slope-intercept form
y = ax + b
"a" is the slope of the line, "b" is the y- intercept (the y-value when x = 0).
the slope is the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
for l we go from (5, 20) to (8, 80) and get
x changes by +3 (from 5 to 8)
y changes by +60 (from 20 to 80)
the slope is therefore
+60/+3 = 20/1 = 20 = a
so, we have
y = 20x + b
the y- intercept looks to be -80, but to be sure we use a point (e.g. 5, 20)
20 = 20×5 + b = 100 + b
b = -80
yes, the equation is
y = 20x - 80
for m we go from (5, 20) to (8, -40) and get
x changes by +3 (from 5 to 8)
y changes by -60 (from 20 to -40)
the slope is
-60/+3 = -20/1 = -20
we have therefore
y = -20x + b
we use the same trick for b as before
20 = -20×5 + b = -100 + b
b = 120
and our full equation is
y = -20x + 120

For which interval(s) is the function increasing and decreasing?
y = |2x^2+x-6|
Answers
From the graph of the function, it's behavior on the intervals is given as follows:
Increasing: x >0.Decreasing: x < 0.When a function is increasing?Looking at the graph, we get that a function f(x) is increasing when it is "moving northeast" along the xy-plane, that is, to the right and up on the graph, meaning that when x increases, y increases.
Hence, from the graph of the function, it is increasing for the values to the right of x = 0, that is, on the interval x > 0.
When a function is decreasing?Looking at the graph, we get that a function f(x) is decreasing when it is "moving southeast" along the xy-plane, that is, to the right and down on the graph, meaning that when x increases, y decreases.
Hence, from the graph of the function, it is decreasing for the values to the left of x = 0, that is, on the interval x < 0.
The graph of the function is shown at the end of the answer.

How to solve the Inequality?We are given the Inequality expression as;
6x² - x < 2
To express the function in quadratic form, we subtract 2 from both sides to get;
6x² - x - 2 < 0
We now factorize this expression to get;
(2x +1)(3x - 2) < 0
This means that we have two inequalities solution which are expressed as; (2x + 1) < 0 and (3x - 2) < 0
For (2x + 1) < 0, add 1 to both sides to get;
2x < 1
divide both sides by 2 to get;
x < 1/2
Similarly, for (3x - 2) < 0;

Comparing figures with similar appearances but different scales or measures is possible using the scale factor. Take into account two circles that resemble one another but could have various radii. The scaling factor shows how much a figure has grown or shrunk from its starting point.
Any original shape can be designed as an extended or condensed version by using a scaling factor. In the equation y = Kx, K is the scaling factor for x.
The scale factor formula is provided by:
