Answer:
The scale factor is 1/4
Step-by-step explanation:
Here, we are interested in finding the scale factor that helped convert the first point to the second.
Hence, what turned (8,12) to (2,3)
What we shall do here is to simply divide term 2 by term i.e
That would be 2/8 or 3/12 = 1/4
The scale factor was 1/4.
Given that,
The point (8, 12) was dilated to become point (2, 3).
We have to determine,
What was the scale factor?
According to the question,
Scale factors are closely related to the concepts of ratio and proportions.
In ratio and proportions, we multiply or divide a given amount to form a new quantity.
The point (8, 12) was dilated to become point (2, 3).
Therefore,
The scale factor was,
[tex]\rm Scale\ factor = \dfrac{New \ point \ lies \ on \ axis}{Old \ point \ lies \ on \ axis}[/tex]
Substitute the points in the formula for the x-axis,
[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ x-axis}{Old \ point \ lies \ on \ x-axis}\\\\Scale\ factor = \dfrac{2}{8}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]
And substitute the points in the formula for the y-axis,
[tex]\rm \rm Scale\ factor = \dfrac{New \ point \ lies \ on \ y-axis}{Old \ point \ lies \ on \ y-axis}\\\\Scale\ factor = \dfrac{3}{12}\\\\Scale\ factor = \dfrac{1}{4}\\\\[/tex]
Hence, The scale factor was 1/4.

Write the equation in standard form. 0.5x = y - 4
Answer:
y = 0.5x + 4, or y = 1/2x + 4 (if you prefer fractions)
Step-by-step explanation:
y = mx + b (slope intercept form / standard form) ; m = 0.5 or 1/2, b = 4.
m = linear coefficient/slope(denoted by a in a 1 degree binomial)
b = constant coefficient / y-intercept (denoted by b in a 1 degree binomial)
to convert this equation into a standard form equation. You need to isolate y and leave the coefficients on the other side.
0.5x = y - 4
0.5x (+4) = y - 4 (+4)
0.5x + 4 = y
y = 0.5x + 4
Answer:
y=0.5x+4
Step-by-step explanation:
0.5x= y-4
add 4 on both sides
and then you get:
y=0.5x+4

Please help me out!
Answer: Rotate 180 degrees around the origin
You can do this clockwise or counterclockwise.
Whenever we move from one quadrant to the complete opposite quadrant like this, we perform a 180 degree rotation. Connect any preimage point to its corresponding image point, and this segment will go through the origin. This works because the origin is the center of rotation, and only works with 180 degree rotations.

A gym membership costs $110 to open and $30 per month after
1. What is the dependent and independent variable
2. Explain how you know the variables are independent or dependent
3. Is the relationship linear or non linear? Explain your reason
4. Do you think that given enough information you could create a table,graph, and an equation for the function? Why or why not
5. What information would you need to make your table/graph/equation?
Answer:
1) The dependent variable is the monthly charge and the independent variable is the $110 to open the membership.
2)The dependent variable is the monthly charge because it will change depending on how many months you plan to keep your membership.
3)This relationship is linear because it will go up by $30 every month.
4)You could create a graph off of this information because all you would need to do is graph the cost each month.
5)I would need the number of month that I would keep the membership going and the amount that i have already paid.
Wally's grandmother started a college savings account for him with
$3,000. What is the total amount of money in the account after 5 years if
the annual simple interest rate is 3%?
I need this plz help explain the proses thx ASAP
Answer:
$450
Step-by-step explanation:
You want to calculate the interest on $3000 at 3% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $3000.00.
r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 3000 × 0.03 × 5 to get that:
The interest is: $450.00
Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),
or 3000.00 + 450.00 = 3450.00.

====================================================
Explanation:
Check out the diagram below. I recreated the diagram in your textbook, but I added on a few other points and segments.
Point E is the midpoint of segment AB. Segment OE is perpendicular to AB.
Point F is the midpoint of CD. Segment OF is perpendicular to CD.
Right triangle AOE forms with OA = 10 as the hypotenuse (radius of the circle) and AE = 8, since E cuts AB in half.
Use the pythagorean theorem to find that...
a^2+b^2 = c^2
(AE)^2 + (OE)^2 = (OA)^2
8^2 + (OE)^2 = 10^2
64 + (OE)^2 = 100
(OE)^2 = 100-64
(OE)^2 = 36
OE = sqrt(36)
OE = 6
--------------------
Because chord CD is the same length as chord AB, this means the chords are the same distance from the center point O.
So, OE = OF = 6
Since we have rectangle OEPF, the opposite sides are congruent and we can say OF = EP = 6
Now focus on right triangle OEP. Use the pythagorean theorem again
a^2+b^2 = c^2
(OE)^2 + (EP)^2 = (OP)^2
(6)^2 + (6)^2 = (OP)^2
72 = (OP)^2
(OP)^2 = 72
OP = sqrt(72)
OP = sqrt(36*2)
OP = sqrt(36)*sqrt(2)
OP = 6*sqrt(2)

Answer:
i think it’s y = -3/4
Step-by-step explanation:
Write the equation of a line that is perpendicular to y = 7/5x + 6 and that passes through the point (2,-6).
Answer:
y = -5/7x - 32/7
Step-by-step explanation:
Perpendicular slopes are "opposite reciprocals."
7/5 goes to 5/7, then -5/7 (if you don't get it you can comment)
So the perpendicular equation line: y = -5/7x + b (you don't know the y-intercept yet)
Substitute (2, -6) because that perpendicular line is going through it.
-6 = -5/7(2) + b
-6 = -10/7 + b
-42/7 = -10/7 + b
-32/7 = b
Perpendicular line equation: -5/7x -32/7
