This year, Ms. Makratzaki’s small hardware store had sales of $536,000. Five years ago, the store had $441,000 in sales, and last year it had $517,000 in sales. Assuming a constant rate of increase, predict the amount of sales the store will have after 8 years.

$650,000
b.
$669,000
c.
$688,000
d.
$707,000
Please select the best answer from the choices provided
A
B
C
D
Answers
Explanation - 536-517 = 19 so 19000 x 8 + 536000 = 688,000
Thinking it as a propotional increase, find the unit rate of change.
values: (0, 536,000), (-5, 441,000), (-1, 517,000)
unit rate of change:
[tex]\sf \dfrac{y2-y1}{x2-x1}[/tex]
[tex]\dashrightarrow \sf \dfrac{536,000-441,000}{0-(-5)}[/tex]
[tex]\dashrightarrow \sf 19000[/tex]
Therefore, the sales increase by $19000 each year.
After 8 years the sale increasement:
$19000 * 8$152000Total sales amount:
current sales + increasement in sales$536,000 + $152000$688,000So, correct answer is : $688,000

Find the equation of a line which is parallel to the line with the equation 2x + y = 4 and
which passes through the origin.
Answers
Answer:
y = -2x
Step-by-step explanation:
Given
2x + y = 4Passes through the origin (0, 0)Solving
Rewriting the equation
2x + y = 4y = -2x + 4New equation
The slope of the new line is the same (-2) because it is parallelThe y-intercept is (0, 0)⇒ y = mx + b [m = slope, b = y-intercept]
⇒ y = -2x + 0
⇒ y = -2x
Answer:
2x+y=0
Step-by-step explanation:
Given:
[tex]\displaystyle \large{2x+y=4}\\\displaystyle \large{y=-2x+4}[/tex]
To find:
The equation of line that’s parallel and passes through origin point.Parallel Definition:
Both lines have same slope.Slope-Intercept:
[tex]\displaystyle \large{y=mx+b}[/tex]
m = slopeb = y-interceptTherefore, another line is:
[tex]\displaystyle \large{y=-2x+b}[/tex]
Since the line passes through origin point which is (0,0). Substitute x = 0 and y = 0 in the equation:
[tex]\displaystyle \large{0=-2(0)+b}\\\displaystyle \large{b=0}[/tex]
Therefore, the equation is:
[tex]\displaystyle \large{y=-2x}[/tex]
Convert back to standards form:
[tex]\displaystyle \large{2x+y=0}[/tex]
Therefore, another line that is parallel to [tex]\displaystyle \large{2x+y=4}[/tex] is 2x+y=0

the
Cole has a rectangular garden
square meters. The length of
the garden?
4.5 meters. What is the width, in meters, of
garden is
Answers
Answer
The width is 3.56
Step-by-step explanation:
Area=length × width
The area is 16.02
The length is 4.5
The width is unknown so we are going to call it X
4.5X=16.02
divide 16.02/4.5 = 3.56
3.56 meters
The formula for area of a square is length * width = area
So divide the length from the area to found out our width
16.02 / 4.5 = 3.56

2 units left2 units downreflection across the y-axisStep-by-step explanation:
The letters designating the original figure, RSTU, start at the bottom of the figure and proceed clockwise around it. The letters designating the image, R'S'T'U' start at the bottom and proceed counterclockwise around it. This tells you ...
the figure has been reflected once (CW-CCW order is reversed)the line of reflection is a vertical line (up-down orientation hasn't changed)__
The fill-in for the answer tells you that translation takes place before reflection. To figure out how much translation is needed, you need to know the line of reflection.
Line of ReflectionYou can look at the reflection choices to see where the line of reflection is. We're guessing that the only vertical line choice is the y-axis. (If the line of reflection is x=1, there doesn't need to be any horizontal translation.) If the image is reflected across the y-axis, the point R' moves from (-3, 0) to (3, 0). This is where R' is reflected from.
TranslationThe point R is at (5, 2). To move R from (5, 2) to (3, 0) prior to reflection, the x-coordinate needs to decrease by 2 (from 5 to 3), and the y-coordinate also needs to decrease by 2 (from 3 to 0). That is, the point R must be translated left 2 and down 2 to get it to (3, 0).
__
R'S'T'U' is the image of RSTU after translation 2 left, 2 down, and reflection across the y-axis.

b.Write and graph an inequality to represent the total number of calories Michael Phelps consumed each day.
2. Write a situation about Michael Phelps in which the inequality 3m + 2,000 ≥ 8,000 would represent the situation.

Answer:
111-(9*12)=3.
Step-by-step explanation:
There are 111 ounces of orange paint, which is going to go into the other bottles. How many bottles? 9. However, because in life we have different sized bottles, it states each bottle takes 12 ounces. In order to find the amount of ounces needed to find all 9 bottles, we first multiply 9*12, which equals 108. Filling all the bottles with orange paint will take up 108 ounces of the orange paint. We do have enough, since we have 111 ounces, but we must find how many ounces we have now that we've used up 108, which can be done by subtraction. 111-108=3. We have 3 ounces left over.
Now we translate everything we did into a mathematical equation. First, we multiplied, and then we subtracted the product from 111. 111-(9*12), which equaled 3, so 111-(9*12)=3. The parentheses technically aren't necessary, because if this is solved according to PEMDAS (the order of operations), the multiplication will occur first anyway.
