Answer:
[tex]\bold{m=-\dfrac92=-4.5}[/tex]
Step-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(2, -9) ⇒ x₁ = 2, y₁ = -9
(-2, 9) ⇒ x₂ = -2, y₂ = 9
So the slope:
[tex]\bold{m=\dfrac{9-(-9)}{-2-2}=\dfrac{18}{-4}=-\dfrac92}[/tex]

Step-by-step explanation:
it can't be any of the answers that have addition because -4 has to move up 8 spaces on the y axis to get to +4 and -2 needs to move up 4 spaces to get to +2 and you can only use 1 rule so A is correct

Find the length of side x in the simplest radical form with a rational denominator
Answer:
The value of x = 1
Step-by-step explanation:
Given
hypotenuse = √2 angle Ф = 45°To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 45°
adjacent of 45° = x
hypotenuse = √2
so substituting Ф = 45° adjacent = x and hypotenuse = √2 in the equation
cos Ф = adjacent / hypotenuse
[tex]\cos \left(45^{\circ \:}\right)=\frac{x}{\sqrt{2}}[/tex]
switch sides
[tex]\frac{x}{\sqrt{2}}=\cos \left(45^{\circ \:}\right)[/tex]
Multiply both sides by 2
[tex]\frac{2x}{\sqrt{2}}=2\cos \left(45^{\circ \:}\right)[/tex]
[tex]\sqrt{2}x=\sqrt{2}[/tex] ∵ [tex]\cos \left(45^{\circ \:}\right)=\frac{\sqrt{2}}{2}[/tex]
Divide both sides by √2
[tex]\frac{\sqrt{2}x}{\sqrt{2}}=\frac{\sqrt{2}}{\sqrt{2}}[/tex]
[tex]x=1[/tex]
Therefore, the value of x = 1
The vertices of a triangle are P[4.1). Q(2.-8), and R(-8.1). What are the vertices of the image reflected across the y-axis?
O A P14.-1), Q12,8), and RX-8.-1)
B. PY-4. 1). Q1-2.-8), and R(8.1)
OC. P(-4,-1). QT-2,8), and R18.-1)
OD. P14.1). Q12.-8), and R1-8.1)
Given:
The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1).
To find:
The vertices of the image reflected across the y-axis.
Solution:
The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1). It is reflected across the y-axis.
If a figure is reflected across the y-axis, then
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]P(4,1)\to P_1(-4,1)[/tex]
[tex]Q(2,-8)\to Q_1(-2,-8)[/tex]
[tex]R(-8,1)\to R_1(8,1)[/tex]
So, the vertices of the image are [tex]P_1(-4,1), Q_1(-2,-8), R_1(8,1)[/tex].
Therefore, the correct option is B.
Note: Options are not in proper form.
Answer:
P'(–4, 1), Q'(–2, –8), and R'(8, 1)

Select the graph for the solution of the open sentence. Click until the correct graph appears.
IX - 1l <4
Answer:
Here we can not see the options, so i will find the graph by the equation alone.
We start with:
Ix - 1I < 4
We could rewrite this as:
-4 < (x - 1) < 4
Now we can add 1 in the 3 parts, to get:
-4 + 1 < x - 1 + 1 < 4 + 1
-3 < x < 5
This means that the graph will be such that:
x > -3 (this is a dashed line at x = 3, and we shade the part in the right of that line)
and:
x < 5 (this is a dashed line at x = 5, and we shade the part in the left of that line)
The graph would look something like the one below
(If the graphs are only in one axis, you should see a white dot at x = -3, than a colour line that goes to the right until the point x = 5, where we have another white dot)
Please help out, what is the slope here? This question is worth 20 points
Answer:
the slope is 1
you find two points that are directly on an intersection of the grid. and then count rise/run
rise is going up and down and run is left and right
start at the point you found furthest to the left and count to the next point that's to the right.
if you have to go down to find it or left to find it, the slope is negative
in this case. theres a point at (-1,0) and (0,1)
you have to count up one and right one, making the slope 1/1 or simplified to 1

What is the slope of the line through the points (-4, 2) and (-16, -6)?
2/3
−5/2
2/5
3/2
Answer:
The slope is equal to [tex]\frac{2}{3}[/tex] . So the right answer is A.
Step-by-step explanation:
We know that if we are given to points of a function we can find out its slope by using the following formula....
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Where m is the slope, [tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the coordinates of the first point, [tex]x_{2}[/tex] and [tex]y_{2}[/tex] are coordinates of the second point.
Let (-4, 2) be [tex](x_{1} , y_{1})[/tex]
Let (-16, - 6) be [tex](x_{2}, y_{2} )[/tex]
then......
The slope of the line will be [tex]\frac{2}{3}[/tex] i.e. option A is the correct answer.
What is slope?Slope is or gradient of a line is a number that describes both the direction and the steepness of the line.
Slope [tex](m) =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
We have,
Points (-4, 2) and (-16, -6)
i.e.
x₁ = -4, x₂ = -16,
And,
y₁ = 2, y₂ = -6
Now,
Using the above mentioned formula,
Slope [tex](m) =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
i.e.
Slope [tex](m) =\frac{-6-2}{-16-(-4)}[/tex]
On solving we get,
Slope [tex](m) =\frac{-8}{-12}=\frac{2}{3}[/tex]
So, the slope pf the given points is [tex]\frac{2}{3}[/tex] .
Hence, we can say that the slope of the line will be [tex]\frac{2}{3}[/tex] i.e. option A is the correct answer.

Percents
Michael is leaving a 15% tip for his waitress. What percent of the
original price will he pay? Write your answer as a percent, decimal,
and fraction.
Answer:
As a percent: 115%
As a decimal: 1.15
As a fraction: [tex]\frac{23}{20}[/tex]
Step-by-step explanation:
Percentages
Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.
Thus, he is really paying 100%+15% = 115% of the original price.
To express a percentage as a decimal, we just divide by 100:
115% = 115/100 = 1.15
The same division should be simplified instead of operated to express the percentage as a fraction:
115% = [tex]\frac{115}{100}[/tex]
Simplifying by 5:
115% = [tex]\frac{23}{20}[/tex]
Summarizing:
As a percent: 115%
As a decimal: 1.15
As a fraction: [tex]\frac{23}{20}[/tex]
