Determine the domain and range of the following relation.
x + 2 = [y]
Answer:
Domain: all real numbers
Range: all real numbers
Step-by-step explanation:
y = (?) 25°, 30° Please Help
Answer: if you’re asking for the missing angle then it’s 125°
Step-by-step explanation:
triangles always equal 180°
i’m assuming 25° and 30° are the other angle measures so
25° + 30° = 55°
180° - 55° = 125°
so the missing angle is 125°

Given that Segment BE is 5 units, find the indicated measures for Angle 1, Angle 2, Segment AC, Segment AD.
Answer:
Segment AC = 10 units
segment AD =
angle 1 = 45°
angle 2 = 90°
AE = BE = CE = DE = 5
SEGMENT AC = AE + CE
= 5 + 5
= 10 UNITS
SEGMENT AD = 5² + 5²
= √50
= 7.071
= 7 UNITS
ANGLE 1 = 90° ÷ 2
= 45°
ANGLE 2 = 360° ÷ 4 / 180° ÷ 2
= 90°
HELP!!! Which equation below shows the relationship for the graph?
Help please please!!!!!!!
Answer:
I'll do the first one as an example. The answer of the first one is 6.
Step-by-step explanation:
In the first example, they multiplied the number by 2 to get a common denominator for the two fractions so you can easily add. So, the first box will come 10 (5 times 2) and the second box will become 2 (1 times 2). Then simply add the fractions. The sum of the first question is 2. Because 2 10/12 + 3 2/12 = 6. Remember to add only the whole numbers and fractions. If you want, you can try using mathaway for additional help.
Hope this helps a little more.

Answer
well if dora earns a monthly salary of $3,568 and she gives boots $1189 and gives swiper the fox $1189 and keeps $1189 for herself that she can buy starbucks and clothes
Step-by-step explanation:
Answer:
3,694.71 dollars
Step-by-step explanation:
Given the following question:
Dora earns a monthly salary of $3,568...
She also earns a 1% commission...
Last month she sold $12,674 worth of products
To find the answer we have to find 1% of her last month's pay and then add that number to her monthly salary.
1% of $12,674
[tex]\frac{1\times12674}{100} =1\times12674=12674\div100=126.74[/tex]
1% of $12,674 is $126.74
[tex]3568+126.71=3694.71[/tex]
The number is already rounded to the nearest hundredth's place.
[tex]=3694.71[/tex]
So, in total Dora earns "$3,694.71" for last month.
Hope this helps.
Graph the data.
Find and interpret the slope of the line through the points.
I need help again!! Please hurry!!
Answer:
Given that angle DGC is 90 degrees and is vertical to AGB, they both are congruent so they will both have the same degrees.
So now we know angle AGB is 90 degrees
Angle AGE is 30 degrees, and in total all the angles would be equal to 180 degrees.
Now we just solve for x,
30 + 90 + x = 180
120 + x = 180
-120 -120
x = 60

The length of three snakes exhibited and the zoos reptile house are labeled. The king snake is 65 inches. The Easter diamondback rattlesnake is 2 yards. The ridge nosed rattlesnake is 4 feet. Which statement correctly compares the length of the snakes?
A. The king snake is the longest snake.
B. The ridge nosed rattlesnake is longer than the eastern diamondback rattlesnake.
C. The eastern diamondback rattlesnake is the longest snake.
D. The eastern diamondback rattlesnake is shorter than a king snake.
Answer:
C
Step-by-step explanation:
King Snake: 65 inches / 12 inches per foot = about 5.4 feet long
Eastern Diamondback Rattlesnake: 2 yards * 3 feet per yard = 6 feet long
Ridge Nosed Rattlesnake: 4 feet long
Therefore, the eastern diamondback rattlesnake is the longest snake.
To be eligible for the senior admission rate, a visitor must be at least 65 years old.
Use y to represent the age (in years) of a visitor who gets the senior rate.
At the airport, each piece of luggage to be checked in must not weigh more than 55 pounds.
Use w to represent the weight (in pounds) of a piece of luggage that can be checked in.
Answer:
y ≥ 65
w ≤ 55
Step-by-step explanation:
1)To be eligible for the senior admission rate, a visitor must be at least 65 years old. Use y to represent the age (in years) of a visitor who gets the senior rate.
"At atleast 65 years" is the same as being 65 years old or olderIf y is represented by age, the correct equation is y ≥ 652)At the airport, each piece of luggage to be checked in must not weigh more than 55 pounds. Use w to represent the weight (in pounds) of a piece of luggage that can be checked in.
"not weigh more than 55 pounds" is the same as having it weigh 55 pounds or lessIf w is presented by the weight, the correct equation is w ≤ 55-Chetan K

Which expressions are polynomials?
Select each correct answer.
Answer:
the second and third one
Step-by-step explanation:
Which of the following are negative reciprocals?
A. 3/4 & -4/3
B. 3/4 & -3/4
C. 3/4 & 4/3
D. 3/4 & 3/4
Answer:
option A is the answer because -4/3 is both negative and reciprocal of 3/4
Answer:
A. 3/4 & -4/3
Step-by-step explanation:
Negative reciprocal is the negative of the value and the numerator/denominator is switched to denominator/numerator.
For example, -7/15.
-7 is the numerator because -7 is above 15. But if we switch that, it will become -15/7. If we turn it from negative to positive or positive to negative, which in this case is negative to positive, since negative x negative is positive, it will become 15/7. I really took the time to explain this, so I hope this helps. =D

Choose the equation of the line in slope-intercept form.
Perpendicular to the X-axis and has the point (3,4)
A. y = 3
B. y = 4
C. x = 3
D. x = 4
Answer:
C) x = 3
Step-by-step explanation:
Equation of a line in slope-intercept form: y = mx + b
(where m is the slope (gradient) and b is the y-intercept)
If the line is perpendicular to the x-axis, the line will be parallel to the y-axis (vertical). We are told that the line passes through point (3, 4). Therefore, the line will never intercept the y-axis and so the y-intercept is zero. Also, all the values of x = 3
So the equation of the line is: x = 3
Mattie Evans drove 200 miles in the same amount of time that it took a turbopropeller plane to travel 950 miles. The speed of the plane was 150 mph faster than th
speed of the car. Find the speed of the plane.
The speed of the plane was mph.
(Simplify your answer.)
Answer:
speed of the plane = 190 mph
Step-by-step explanation:
Let x = speed of the plane, then speed of the car = x - 150
time = 200/(x - 150) = 950/x
Divide by 50 on both sides, get
4/(x - 150) = 19/x
Cross multiply:
4x = 19(x - 150)
4x = 19x - 19*150
15x = 19*150
x = 19*150/15 = 190

Answer:
(4, 360)cost of repair in either shop is 360 for 4 hours workAmy's is cheaper for 3 hours. $280Step-by-step explanation:
1.Each of the given equations describes a line on a graph. There are numerous ways to find the values of x and y that will satisfy both equations at the same time. Two of them you have seen are "substitution" and "elimination." Here, "substitution" is easily accomplished by equating one expression for y to the other expression for y:
y = y
100 +65x = 40 +80x . . . substitute for y
60 +65x = 80x . . . . . . . subtract 40 from both sides
60 = 15x . . . . . . . . . . . . subtract 65x from both sides
4 = x . . . . . . . . . . . . . . divide both sides by 15
y = 40 +80x = 40 +80(4) = 360 . . . . find the value of y
The values of x and y that satisfy both equations are ...
(x, y) = (4, 360)
__
2.The point (4, 360) is on both lines. That is the point where the lines intersect. It means 4 hours work will cost $360 in either shop.
__
3.The time of 4 hours that we found above is the "break-even" or "crossover" point in the cost equations. For times below that point, the lowest cost comes because of the lowest "service charge". For times above that point, the lowest cost comes because of the lowest per-hour charge.
3 hours is less than 4 hours, so the shop with the lowest service charge will have a lower cost. That is Amy's shop. Her price for 3 hours is ...
40 +80(3) = 40 +240 = $280 . . . for 3 hours work in Amy's shop
__
If you want to make sure of that, you can find the cost in Mike's shop:
y = 100 +65(3) = 100 +195 = $295 . . . for 3 hours in Mike's shop
7 pounds of plums make 8 rolls of fruit leather. If every batch of fruit leather requires the
same amount of plums, how many pounds of plums are required to make 20 rolls of fruit
leather?
Answer: 17.5 lbs of plums are required to make 20 rolls of fruit leather.
Step-by-step explanation:
Since 7 lbs of plums yield 8 rolls of fruit leather, 1 lb will yield 1 1/7 rolls of fruit leather.
To find how many pounds of fruit will yield 20 rolls of fruit leather, divide how many rolls of leather you want to get by how many rolls of leather one pound will yield.
20 divided by 8/7 equals 17 1/2.
