-3
Parallel lines have slopes which are equal to each other.
We know that y = 3x + 2 has a slope of 3, therefore, the line parallel to y = 3x + 2 has a slope of 3.

Raymond and Rose were working with exponents.
Part A: Raymond claims that 5⁵ * 5² =5³ Rose argues that 5⁵ * 5² = 5⁷. Which one of them is correct? Use the properties of exponents to justify your answer.
Part B: Raymond claims that 7⁹/7⁵ = 7⁴. Rose argues that 7⁹/7⁵=7⁴⁵. Which one of them is correct? Use the properties of exponents to justify your answer.
Answer:
Part A : Rose is correct
Part B : Raymond is correct
Step-by-step explanation:
Part A:
Raymond claims that 5⁵ * 5² =5³
Rose argues that 5⁵ * 5² = 5⁷.
Which one of them is correct?
Rose is correct
Use the properties of exponents to justify your answer.
Using the properties of exponents,
x^a × x^b = x^a+b
From the above question, following the above rule we have:
5⁵ * 5² = 5⁵+²
= 5⁷
Hence, Rose is correct.
Part B: Raymond claims that 7⁹/7⁵ = 7⁴. Rose argues that 7⁹/7⁵=7⁴⁵.
Which one of them is correct?
Raymond is correct
Use the properties of exponents to justify your answer.
Using the properties of exponents,
x^a / x^b = x^a-b
From the above question, following the above rule we have:
7⁹/7⁵ = 7⁹-⁵
= 7⁴
Hence, Raymond is correct.

AC CE and D is the midpoint of CE. IF CE 10x + 18, DE =7x -1, and BC = 9x - 2, find AB, AB =
Answer:
If you mean: AC=CE, the answer is: AB = 24Step-by-step explanation:
D is the midpoint of CE, then
CD = DE = 0.5CE = 0.5(10x+18) = 5x + 9
So: 5x + 9 = 7x - 1
-9 -9
5x = 7x - 8
-7x -7x
-2x = -8
÷(-2) ÷(-2)
x = 4
AC = CE = 10x + 18 = 40 + 18 = 58
BC = 9x - 2 = 36 - 2= 34
AB = AC - BC = 58 - 34 = 24
D is the midpoint of CE, so if you draw a line with those three points, it'll look like C-D-E.
Since DE = 7x-1, which also means CD = 7x-1.
CD + DE = CE, so (7x-1)+(7x-1) = 10x+18.
Therefore, x = 5 and CE = 68.
Since AC is congruent to CE, AC = 68.
Assuming the point B is somewhere between AC.
Since BC = 9x-2 and x = 5, which means BC = 43.
AC - BC = AB, so 68 - 43 = 25.
Therefore, AB = 25
Help me with this pls
Answer:
x=55, and y=62.5
Step-by-step explanation:
The reason why x=55 is because x and the angle 125 degrees form a linear pair (180 degrees) Hence,
x+125=180
=> x=180-125
=> x=55
Now coming to y, As we see y and 125 do not form a linear pair, so we know that x=the top angle of the triangle in which angle y is there. And with the information we also find that the triangle in which y is present is an isosceles triangle, so the other 2 angle than the top angle are equal, which are y and another angle which is also y as they are the same degrees. Hence, we know x=55, then,
55+2y=180(As the angles in a triangle sum up to 180 degrees)
=> 2y=180-55
=> 2y=125
=> y=125/2
=> y=62.5

a pet store has 7 cats here are their weights 12, 12, 9, 16, 11, 11, 9 find the mean weighy of these cats
Answer:
The mean weight of the cats is 11.42 (rounded)
Step-by-step explanation:
To find the mean, you add up all the weights (12, 12, 9, 9, 11, 11, 16) and then divided the sum (80) of the weights by the number of cats (7)
12+12+9+9+11+11+16= 80
80 ÷ 7= 11.42857143 (I rounded my answer to 11.42)

A student runs 100 meters in 11 seconds. What is the speed of the student in miles?
Answer:
0.00565 miles / second
Step-by-step explanation:
1 mile = 1609.344 meters
100 meters = 100/1609.344 = 0.0621 miles (aprox)
100 meter/ 11 seconds = 0.0621miles / 11 seconds
= 0.00565 miles / second

x² - 6x + _____ + y² + y + _____ = 1 + ____ + ____

-6/2 = -3 1/2 = 1/2
Equation: (x - 3)² + (y + 1/2)² = r²
Since the circle passes through point (x, y) = (4, -2), input that into the equation to find r².
(x - 3)² + (y + 1/2)² = r²
(4 - 3)² + (-2 + 1/2)² = r²
(1)² + (-3/2)² = r²
1 + 9/4 = r²
13/4 = r²

Here, we need to find x. So, Let's isolate x on one side of the equation. It is present in the left hand side. Add 5 to both sides,
[tex]2x - 5 + 5 = 7 + 5[/tex]
[tex]2x = 12[/tex]
Divide 2 from both sides,

What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a swimmer dives straight into the ocean. His depth, d, in meters after t seconds, can be modeled using the equation d = (t - 3)² - 16.
The time will be calculated as below;-
d = ( t - 3 )² - 16.
16 = ( t - 3 )² - 16
32 = ( t - 3 )²
√32 = t - 3
5.67 = t - 3
t = 5.67 + 3 = 8.67 ≅ 9 seconds
Therefore, the time taken by the swimmer to reach the lowest depth will be 9 seconds. The correct option is D.

Water flowed out of a tank at steady rate. A total of 18 1/2 gallons flowed out of a tank in 4 1/4 hours. Which expression determines the the quality of water leaving the tank per hour?
O 17/4 divide 36/2
O 36/2 divide 17/4
O 17/4 divide 37/2
O 37/2 divide 17/4
Answer: In 1 hour water flowed out = 74/17 gallons
Step-by-step explanation:
Given as ,
The quantity of water flowed out of tank = 18 1/2 gallons
= 37/2 gallons
The time spend in flowing water out of tank = 4 1/4 hours
= 17/4 hours
∵ In 17/4 hours , water flowed out = 37/2
∴ In 1 hours , water flowed out =
So, in 1 hour water flowed out = 37*4/17*2 gallons Answer
Answer:
total galloons flowed=18 1/2=36/2
time that it flowed=4 1/4=16/4
rate=total galloons flowed/time to flow
rate=36/2÷16/4
=9/2gallons per hour
4.5gallons per hour
