What rule describes a dilation with a scale factor of 1/2 and the center of dilation at orgin.
Answers
Explanation:
When we dilate a point by a scale factor "a" and the center of the dilation is the origin, the original point (x,y) changes as follows:
[tex](x,y)\rightarrow(ax,by)[/tex]Each coordinate value is multiplied by the scale factor.
In this case, the scale factor is 1/2:
[tex]a=\frac{1}{2}[/tex]Therefore, the transformation rule is:
[tex](x,y)\rightarrow(\frac{1}{2}x,\frac{1}{2}y)[/tex]This rule is shown in option C.
Answer:
C.

Answers
Let two unknow positive number is "x" and "y"
Difference of two positive number is 6 that mean:
[tex]x-y=6[/tex]Their product is 223 less than the sum of their square:
[tex]\begin{gathered} x\times y=x^2+y^2-223 \\ xy=x^2+y^2-223 \end{gathered}[/tex]Substitute x with variable y:
So,
[tex]\begin{gathered} x-y=6 \\ x=6+y \end{gathered}[/tex]Put the value of "x" in another equation:
[tex]\begin{gathered} xy=x^2+y^2-223 \\ (6+y)y=(6+y)^2+y^2-223 \\ 6y+y^2=36+y^2+12y+y^2-223 \\ y^2+6y-187=0 \\ y^2+17y-11y-187=0 \\ y(y+17)-11(y+17)=0 \\ (y+17)(y-11)=0 \\ y=-17;y=11 \end{gathered}[/tex]Given number is positive that mean y=11 and so value of x is:

What is the value of x in the triangle below?2460O 12813O 122O 12/3
Answers
The question gives us a right-angled triangle and find the value of x.
In order to solve the problem, we use SOHCAHTOA. In this case, we will use "SOH" from SOHCAHTOA because we have the Opposite as x and Hypotenuse as 24, while the relevant angle is 60 degrees.
Let us apply this formula:
[tex]\begin{gathered} \text{ SOH implies:} \\ \sin \theta=\frac{\text{Opposite}}{\text{Hypotenuse}} \\ \\ \theta=60^0,\text{Opposite}=x,\text{Hypotenuse}=24 \\ \\ \therefore\sin 60^0=\frac{x}{24} \end{gathered}[/tex]We simply need to make x the subject of the formula and we shall also represent sin 60 with its surd form.
This is done below:
[tex]\begin{gathered} \sin 60^0=\frac{x}{24} \\ \text{ Multiply both sides by 24} \\ 24\times\sin 60^0=\frac{x}{24}\times24 \\ \therefore x=24\times\sin 60^0 \\ \\ \sin 60^0=\frac{\sqrt[]{3}}{2} \\ \\ x=24\times\frac{\sqrt[]{3}}{2}=12\times2\times\frac{\sqrt[]{3}}{2}\text{ (2 crosses out)} \\ \\ x=12\sqrt[]{3} \end{gathered}[/tex]Therefore, the final answer is Option 4
give an example of a positive tempature and a negative tempature that have a diffrence of 5 fedagree
Answers
We can think of temperatures above zero F and below zero F. For example weather conditions in cold places like Alaska.
In the morning, the temperature could be 2 degrees F (above zero)), but later towards the night, the temperature could be below zero in three units : -3 degrees F.
So the difference is the distance from zero to 2 (above) and the distance to zero from below 3 (below the zero mark. so these two differences from zero add up as 2 + 3 = 5
The way to do such in one go with math is to write the "difference" (normally associated with a SUBTRACTION, of the form: 2 - (-3), and therefore use that the negative (or opposite) of a negative number is a positive number:
- (-3) = +3
The same happens when we want to compare the difference between
9 - (-15) = 9 + 15 = 24
with the difference:
-15 - 9 = -24
The important thing is to consider the absolute value if we just want to find the number of units between the values, how many units they are separated.
And if we need to find what needs to be added or subtracted to one of them, at that point the sign of the difference is critical. This is because in one case we will need to add to get to the other number, while in the other case we need to subtract.
A group of friends will buy at most 8 snacks at a movie theater and spend no more than $42. They will pay $4.00 for each box of candy and $7.00 for each bag of popcorn. The system of inequalities graphed below represents this information.

the cost of one box of candy = $4
The cost of one bag of popcorn = $7

The system of inequalities represents the situation is as following:

Part B:
We need to find which combination of candy and popcorn could the group buy:
a. 2 candy and 6 popcorn
check for the first inequality : 2 + 6 = 8
check for the second inequality : 2 * 4 + 7 * 6 = 8 + 42 = 50 > 42
So, this option is wrong
b. 3 candy and 4 popcorn
check for the first inequality : 3 + 4 = 7 < 8
check for the second inequality : 4 * 3 + 7 * 4 = 12 + 28 = 40 < 42
So, this option is true
c. 5 candy and 4 popcorn
check for the first inequality : 5 + 4 = 9 > 8
So, this option is wrong
d. 8 candy and 1 popcorn
check for the first inequality : 8 + 1 = 9 > 8
So, this option is wrong
so, the answer of part B is:
option b

Answers
Given:
The objective is to choose the correct graph which shows a positive linear relationship with a correlation coefficient, r, close to 1.
The positive linear relationship represents the increasing values of plots from origin to positive x and positive y axis.
By observing graph A, the plots are scattered all over the quadrant. Hence, it is a weak association.
By observing graph B, the plots are plotted as decreasing in y axis and increasing in x axis. Hence, it is a strong negative association.
By observing graph C, the plots are plotted as increasing in both x axis and y axis. Hence, it is a strong positive association.
Hence, the graph which shows a positive linear relationship with a correlation coefficient, r, close to 1 is graph C.

Practice Skills_Simplifying Equations1. 3( 1/2 - y) = 3/5 + 15y. What isthe solution to the given equation?
Answers
You have the following equation:
3(1/2 - y) = 3/5 + 15y
In order to solve the previous equation you proceed as follow:
3(1/2 - y) = 3/5 + 15y eliminate parenthesis
3/2 - 3y = 3/5 + 15y multiply by 5 both sides
15/2 - 15y = 3 + 75y multiply by 2 both sides
15 - 30y = 6 + 150y sum 30y both sides and subtract 6 both sides
15 - 30y + 30y - 6 = 6 + 150y + 30y - 6 simplify
9 = 180y divide by 180 both sides
9/180 = 180y/180 simplify
1/20 = y
(the multiplication by 5 and 2 is for eliminating denominator with the same number)
Hence, the solution to the given equation is y = 1/20

Parallel lines are coplanar, straight lines in geometry that don't cross at any point. When two planes in the same three-dimensional space are parallel, they never cross. Curves that maintain a set minimum distance from one another and do not touch or intersect are said to be parallel curves.
If parallel lines are cut by a transversal , then corresponding angles are equal in measure.
∴ ∠B≅∠F
∠A≅∠E
∠C≅∠G
∠D≅∠H
If parallel lines are cut by a transversal , then interior angles on the same side are supplementary.
∠C+∠E=180°
∠D+∠F=180°
If one of the angles ( let it be ∠E) formed measures 122°, then m∠C=180°-122°=58°.
m∠B=m∠C=m∠F=m∠G=58°;
m∠A=m∠D=m∠E=m∠H=122°.

Answer:
if angle a measures122 degrees than angle b measures 58 degrees and angle h measures 122 degrees.
Q: what are parallel lines and their angles?
Answer:
Two lines that are stretched into infinity and still never intersect are called coplanar lines and are said to be parallel lines. The symbol for "parallel to" is //.
There are 4 types of angles formed between parallel lines i.e Corresponding angles, alternate angles , Interior angles, adjacent angle

How do you subtract 5/6 - 5/9 then write it as a fraction in simplest form?
Answers
To subtract two fractions we can use the following:
[tex]\frac{a}{b}-\frac{c}{d}=\frac{(a\cdot d)-(b\cdot c)}{b\cdot d}[/tex]So 5/6 - 5/9 is equal to:
[tex]\frac{5}{6}-\frac{5}{9}=\frac{(5\cdot9)-(6\cdot5)}{6\cdot9}=\frac{45-30}{54}=\frac{15}{54}[/tex]Finally, we can simplify the fraction dividing the numerator and denominator by 3, as:
[tex]\frac{15}{54}=\frac{15/3}{54/3}=\frac{5}{18}[/tex]So, the answer is 5/18
Answer: 5/18
