In 1992, there were 41 comma 984 shopping centers in a certain country. In 2002, there were 48 comma 225. (a) Write an equation expressing the number y of shopping centers in terms of the number x of years after 1992. (b) When will the number of shopping centers reach 80 comma 000?
Answer:
Step-by-step explanation:
The equation expressing the number y of shopping centers in terms of the number x of years after 1992 will be LINEAR in nature
The standard equation is expressed as;
y = mx+c
m is the slope
c is the intercept
If in 1992, there were 41,984 shopping centers in a certain country and in 2002, there were 48,225 we can express this as coordinate points
(0, 41984) and (10, 48,225)
Get the slope
m = 48,225-41,984/10-0
m = 6241/10
m = 624.1
Get the intercept, substitute m = 624.1 and the point (0,48225) into the formula y = mx+c
48225 = 624.1(0)+c
48225 = 0+c
c = 48225
Get the required equation
y = 624.1x+48225
a flat for sale sign has a perimeter of 58 inches. the length is 5 inches longer than the width. what is the width?
Answer:
25 inches
Step-by-step explanation:
1. Information that is needed to solve the problem;
The formula for the perimeter is:
2(a+b) = P
where "a" is the length and "b" is the width.
2. Solving the problem;
Substitute the given values into the formula;
2( 5 + b ) = 58
Inverse operations;
2 ( 5 + b ) = 58
/2 /2
5 + b = 29
-5 -5
b = 25

E is the midpoint of DA, and F is the midpoint of DB. This means EF is a midsegment of the triangle. It is half as long as AB, and EF is also parallel to AB.
When we extend EF to form segment EC, it is now twice as long compared to EF. So that shows EC is the same length as AB, in other words, EC = AB. Also, EC is parallel to AB. This works due to points E, F, and C being on the same line.
Since EC || AB, we know that angle EBA = angle BEC. These are alternate interior angles.
From the reflective property, we can say EB = EB
---------------
Using these three facts
EC = ABangle EBA = angle BECEB = EBto prove that triangle EBA is congruent to triangle BEC. The next step is to use CPCTC (corresponding parts of congruent triangles are congruent) to lead to
angle BEA = angle EBC
we can use the alternate interior angle theorem converse to conclude that EA is parallel to BC.
-----------------
In summary, we have proven:
EC is parallel to ABEA is parallel to BCBy the definition of what it means to be a parallelogram, we have proven quadrilateral EABC is a parallelogram. In short, we've shown that the opposite sides are parallel.
question 5 hel ppleade ill give brainliest hdhshdhdh
Answer:
C (Kinda blurry)
Step-by-step explanation:
By looking at the two points you can tell the slope is 1, because it moves 2 over it moves 2 up.
If you back track to find the y value when x=0, then you have the x intercept.
So the equation is y=x+2. In this equation the values are jumbled so you just do a few transformations to make the equation look like the correct one.
subtract y on each side to get 0=x-y+2
subtract 2 from each side to get -2=x-y
now you have x-y=-2

Solve: 2n + 3n - 6 = -21
What does n equal?
- n=5
- n=3
- n= -5
- n= -3
Answer:
n=-3
Step-by-step explanation:
add the like values and add the 6 to the -12 and decide the totals to get -3
Answer:
n=3
Step-by-step explanation:
2n+3n-6=-21
Add 6 on both sides of the equal sign: -6+6=-21+6
2n+3n=15
Combine like terms: 2n+3n
5n=15
Divide by 5 on both sides of the equal sign: 5n/5=15/5
n=3

Step-by-step explanation:
2 inches is 70 miles. .5 inches is 17.5 and add them together and you get 87.5.
Please mark brainliest.
Answer: D. 87.5 miles
Step-by-step explanation:
They have given us a scale that 1 inch = 35 miles.
Since the distance is 2.5 inches, we have to multiply 2.5 inches by 35 miles.
1 in. = 35 miles
2.5 in = x
2.5 times 35 = 87.5 miles

Jake ate 4½ pounds of candy during the week after Halloween. How much candy did he eat per day on average.
Answer: 9/14 of a pound each day.
Step-by-step explanation:
We can convert the mixed fraction into an improper fraction:
4 1/2 → 9/2
Now we divide by 7, since there are 7 days in a week:
9/2 ÷ 7
When we divide, by a number, it can be placed in the denominator:
9/2*7 = 9/14
There's no other way to simplify it, so that's our final answer.

Find the equation of the line that has a slope of -3/4 and a y-intercept of 1
Answer:
y = -3/4*x + 1
Step-by-step explanation:
y = mx + b
m = -3/4
b = 1
y = -3/4*x + 1
The equation of the line that has a slope (-3/4) and y-intercept 1 is
y = (-3/4)x + 1.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope = -3/4
y-intercept = 1
The equation of a line.
y = mx + c
y = (-3/4)x + 1
Thus,
y = (-3/4)x + 1 is the equation of the line.

A quadrilateral WXYZ contains wxy where measure of wxy=92 degrees. Once rotated 270° about the origin and translated 2 units up, what is the measure of W'X'Y'?
A. 108 degrees
B. 98 degrees
C. 92 degrees
D. 88 degrees
Answer:
C. 92 degrees
Step-by-step explanation:
Given that the [tex]\angle{wxy}=[/tex]92° which is one of the angles of the quadrilateral WXYZ
The quadrilateral is first rotated by 270° about the origin and then translated 2 units up, the new position of the quadrilateral is W'X'Y'Z'.
The shape of the quadrilateral is remained unchanged due to rotation and translation, so all the angles of the final quadrilateral W'X'Y'Z' is the same as the angles of the given quadrilateral WXYZ.
So,[tex]\angle{w'x'y'}= \angle{wxy}[/tex]
By using the given value,
[tex]\angle{w'x'y'}=[/tex] 92°
Hence, option (C) is correct.
Rotating and translating quadrilateral WXYZ would not change its angle measure.
The measure of W'X'Y is (c) 92 degrees
The given parameters are:
[tex]\mathbf{WXY = 92^o}[/tex]
Translation and rotation are rigid transformations, and they do not alter the angle measure of the shape being transformed.
This means that: angles WXY and W'X'Y are congruent
i.e.
[tex]\mathbf{WXY = W'X'Y}[/tex]
So, we have:
[tex]\mathbf{W'X'Y = 92}[/tex]
Hence, the true option is (c) 92 degrees
