Rectangle KLMN is graphed on the coordinate plane below. On a coordinate plane, rectangle K L M N has points (2, negative 2), (5, negative 2), (5, negative 4), (2, negative 4). The figure is rotated 360° counterclockwise using the origin as the center of rotation. What is the location of the image of point K? (2, –2) (2, 2) (–2, 2) (–2, –2)
Answer: The correct option is (A) (2, -2).
Step-by-step explanation: Given that rectangle with vertices at K, L, M and N is graphed on the coordinate plane as shown in the figure.The figure is rotated 360° counterclockwise using the origin as the center of rotation.
We are to find the location of the image of point K after the rotation.
We know that
a rotation of 360° in counterclockwise direction about the origin map a point to itself. That is, the co-ordinates of the image point will be same as the original one.
From the figure, we see that the co-ordinates of point K are (2, -2).
Therefore, after rotation of 360° counterclockwise using the origin as the center of rotation,
the co-ordinates of the image of point K will also be (2, -2).
Thus, the location of the image of point K is (2, -2).
Option (A) is CORRECT.

For which inequality would x = 12 be a solution?
12 - x ≥ 4
x + 4 ≤ 12
12 x < 200
12 ÷ x > 12
Answer:
12x < 200
Step-by-step explanation:
12 - x ≥ 4
-x ≥ -8
x ≤ 8
12 is not a solution to this one.
x + 4 ≤ 12
x ≤ 8.
12 is not a solution to this one.
12 x < 200
x < 200/12
x < 16 2/3
12 is a solution.
Sara and her dad visit yo yo yogurt again this time the scale says that Sara has 14 ounces of vanilla yogurt in her cup

Fraction numbers are known as numerator and denominator
On a number line, fractions are expressed in points that lie between two integers
The general form of fractions is
[tex]\dfrac{a}{b}[/tex]
Mixed fractions consist of integers and ordinary fractions
A mixed number is a combination of a whole number and a fraction
Sara has 14 ounces of vanilla yogurt
Her father's yogurt weighs half of much, so her fathers have yogurt :
= 0.5 x 14 ounces
= 7 ounces
Total ounces of yogurt they buy
= 14 + 7 = 21 ounces
for 1 ounces (oz) the conversion = 0.0625 pounds(lbs)
So for 21 ounces there will be
= 21 x 0.0625
= 1.3125 pounds
if we express as a mixed number , it will be :
[tex]=\dfrac{13125}{10000}[/tex]
[tex]=1\dfrac{5}{16}[/tex]
Hence Total pounds of yogurt they buy (as a mixed number) : [tex]1\dfrac{5}{16}[/tex]

What is the range of F?
The range of f as shown in the graph is -6 ≤ f(x) ≤ 5. The correct option is A. -6 ≤ f(x) ≤ 5
Determining the range of a functionFrom the question, we are to determine the range of f.
The range of a function is the set of its possible output values.
The graph of the function, f, is shown in the diagram.
From the graph,
The minimum value of f on the x-axis is -6. That is, f(x) ≥ -6
and
The maximum value of f on the x-axis is 5. That is, f(x) ≤ 5
Combining the two expressions, we get
f(x) ≥ -6 and f(x) ≤ 5
That is,
-6 ≤ f(x) and f(x) ≤ 5
∴ -6 ≤ f(x) ≤ 5
Hence, the range of f as shown in the graph is -6 ≤ f(x) ≤ 5. The correct option is A. -6 ≤ f(x) ≤ 5

What is the volume of a sphere with a radius of 8 m, rounded to the nearest tenth of a cubic meter?
radius= 8 m
to find:the volume of the sphere
solution:[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]
[tex]v = \frac{4}{3} \times \pi \times {8}^{3} [/tex]
[tex]v = 2144.66058 \: {m}^{3} [/tex]
[tex]v = 2144.7 \: {m}^{3} [/tex]
therefore, the volume of the given sphere is 2144.7 cubic meters.
[tex]\large\boxed{Formula: V= \frac{4}{3}\pi {r}^{3}}[/tex]
In this question the radius is given so we'll simply have to substitute the values and solve.
Let's solve!
Substitute the values according to the formula.
[tex]V= \frac{4}{3}\times\pi\times{8}^{3}[/tex]
Calculator value:
[tex]V= 2144.660585 \: {m}^{3}[/tex]
Now, we'll have to round off to the nearest tenth.
The value in hundredths place is greater than 5 so, we will have to round up which means, we'll have to add 1 to the tenths place.
Final answer:
[tex]\large\boxed{V= 2144.7 \: {m}^{3}}[/tex]
Hence, the volume of the given sphere is 2144.7 cubic meters.

Answer:
y = 3x -4
Step-by-step explanation:
The two pairs of x and y values are used to find the slope of the line. That and one of the pairs is used to find the y-intercept. These values are put into the slope-intercept equation to give the equation of the line through the two points.
__
Each (x, y) pair represents a point on a graph. The slope-intercept equation for a line relates all the (x, y) pairs that lie on the line. That equation is ...
y = mx +b . . . . . . where m is the slope, and b is the y-intercept
slopeThe slope is the "steepness" of the line. It is positive when the line goes up to the right, and negative when the line goes down to the right. It is 0 for a horizontal line.
The slope is found from (x, y) pairs using the formula ...
m = (y2 -y1)/(x2 -x1) . . . . . . where (x1, y1) and (x2, y2) refer to different pairs
m = (8 -(-1))/(4 -1) = 9/3 = 3 . . . . using the (x, y) values from the table
y-interceptThe y-intercept (b) is the y-value where the line crosses the y-axis. It can be found by rearranging the slope-intercept equation shown above:
b = y - mx . . . . . . . for a line with slope m and a point (x, y) on the line
Using the first point listed in the table with the value of m we just found, we see that b is ...
b = -1 - 3(1) = -4 . . . . . . for (x, y) = (1, -1) and m = 3
equationNow that we have found m=3 and b=-4 for the points in the table, we can put these values in the slope-intercept equation:
y = mx +b
y = 3x -4 . . . . . equation of the relationship in the table
h(t) = t² – 2t
Evaluate h (x + 2)
Need help I’m reviewing for a final (will leave good review)
Answer:
h(x + 2) = x² + 2x
Step-by-step explanation:
The base function is :
⇒ h(t) = t² -- 2t
⇒ h(t) = t (t - 2)
Substitute x + 2 in place of t :
⇒ h(x + 2) = (x + 2) (x + 2 - 2)
⇒ h(x + 2) = (x + 2)(x)
⇒ h(x + 2) = x² + 2x
[tex]h(t) = t^2 -2t\\\\h(x+2) = (x+2)^2 - 2(x+2)\\\\~~~~~~~~~~~~=x^2 +4x + 4 -2x -4\\\\~~~~~~~~~~~~=x^2 +2x[/tex]
Given f(x) and g(x) = k•f(x), use the graph to determine the value of k.
Step-by-step explanation:
the slope of f(x) = 1
for every increase of x by 1 also y increases by 1.
the slow of g(x) = -2
for every increase of x by one y decreases by 2.
so, we see, as
g(x) = k × f(x)
k = g(x) / f(x) = slope g / slope f = -2/1 = -2
why ? because both functions are linear functions (lines).
they look like
y = ax + b
with a being the slope of the line.
so, when multiplied by k, this is kax + kb, and we see k as factor already in the slope of the line itself.

If p(a) = 0.60 and p(b) = 0.20, then a and b are independent events if
a. p(a and b) = 0
b. p(a and b) = 0.12
c. pla or b) = 0.80
d. pa or b) = 0.12
If A and B are independent variables, P(A and B) =0.12. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that, p(a)=0.60 and p(b)=0.20.
If A and B are independent variables,
P(A and B) =P(P∩B)= P(A) × P(B)
Here, P(P∩B)=0.60×0.20
= 0.12

a car travels at an average speed of 40km/h for 2.2 hours how far did the car travel in km
Answer:
88km
Step-by-step explanation:
If a car travels 40 km in 1 hour, then that same car would travel 40*2.2 km in 2.2 hours.
So, the car travelled 88km in 2.2 hours
Remember that speed is a rate!
Answer:
speed=distance/travel time
distance=2*40+60*3=80+180=260 km
travel time=2+3=5 hrs

What is the solution to this system of equations? 3.2 x 0.5 y = 4.2. negative 1.6 x minus 0.5 y = 3.4. (4.75, 38.8) (4.75, negative 22) no solution infinitely many solutions
The solution to the system of equation is (4.75, -11)
3.2x + 0.5y = 4.2
-1.6x -0.5y = 3.4
How to solve system of equation?
3.2x + 0.5y = 4.2
-1.6x -0.5y = 3.4
add equation(i) to equation(ii)
Therefore,
1.6x = 7.6
divide both sides by 1.6
x = 7.6 / 1.6
x = 4.75
Therefore,
3.2(4.75) + 0.5y = 4.2
0.5y = 4.2 - 15.2
0.5y = -11
y = - 11 / 0.5

Answer:
The solution is x=4.75 and y = -22
Step-by-step explanation:
To find the solution to the system of equations, we will follow the steps below:
3.2x + 0.5y = 4.2 --------------------------------------------------------------------------(1)
-1.6x -0.5y = 3.4 ----------------------------------------------------------------------------(2)
add equation (1) and equation (2)
1.6x =7.6
Divide both-side of the equation by 1.6 to get the value of x
1.6x /1.6 =7.6/1.6
x =4.75
substitute x = 4.75 into equation (1) and solve for y
3.2(4.75) + 0.5y = 4.2
15.2 + 0.5y = 4.2
subtract 15.2 from both-side of the equation
15.2 - 15.2 + 0.5y = 4.2-15.2
0.5y = -11
Divide both-side of the equation by 0.5
0.5y/0.5 = -11/0.5
y = -22
The solution is x=4.75 and y = -22
