Answer:
[tex]\frac{x-5}{x-7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x^2-2x-15}{x^2-4x-21}[/tex] ← factor numerator and denominator
= [tex]\frac{(x-5)(x+3)}{(x-7)(x+3)}[/tex] ← cancel (x + 3) on numerator and denominator
= [tex]\frac{x-5}{x-7}[/tex]
Answer:
[tex]\frac{x-5}{x-7}[/tex] is the answer
Step-by-step explanation:
[tex]\frac{x^{2}-2x -15 }{ x^{2}-4x-21}[/tex]
Factorising,
[tex]\frac{x^{2}-5x+3x-15}{x^{2}-7x+3x-21 }[/tex]
[tex]\frac{x(x-5)+3(x-5)}{x(x-7)+3(x-7)}[/tex]
[tex]\frac{(x+3)(x-5)}{(x+3)(x-7)}[/tex]
[tex]\frac{x-5}{x-7}[/tex]

please help i’ve done a (5x) but i need b) and c)
Answer:
b would be 6xy
c would be 6xy as well
Step-by-step explanation:
Not really sure how to explain it, I just know it
Answer:
b) 6xy
c) 6xy
Step-by-step explanation:
b) 6 × x × y
Since there are no like terms, just straight away remove the multiplication signs. So the answer is:
= 6xy
c) 2 × x × 3 × y
2 and 3 are like terms since they are both natural numbers (positive integers), you can multiply 2 with 3. The answer will be:
= 6xy

If a^2- b^2 = 648 and (a - b) = 24. What is the value
of (a+b)?
what is the mean median mode range of 3,14,7,12,4,9,16,4,8,20
First, order the number set from least to greatest:
3 , 4 , 4 , 7 , 8 , 9 , 12 , 14 , 16 , 20
Mean: You find the mean by combining all the terms, and dividing by the amount of the terms there are in the number set:
(3 + 4 + 4 + 7 + 8 + 9 + 12 + 14 + 16 + 20)/10
(97)/10 = 9.7
Mean: 9.7
Median: You find the median by first ordering the number set from least to greatest, and finding the middle number. Note that if there is a even number of numbers in the set, you find the mean with the two given median digits:
8 & 9 are the median numbers:
(8 + 9)/2 = (17)/2 = 8.5
Median: 8.5
Mode: The mode is the number(s) in the set that shows up the most:
Mode: 4 (shows up one more time than all other numbers)
Range: The range can be found by subtracting the least number from the greatest number in the number set:
Range: 20 - 3 = 17
Range: 17

The rate of change is constant in the graph. Find the rate of change. Explain what the rate of change means for the situation.
A. –3; value drops $3 every year.
B. –1; value drops $1 every year.
C. [tex]-\frac{100}{3}[/tex]; value drops $100 every 3 years.
D. –100; value drops $100 every year.
Answer:
you take 2 points on the graph
(3,300) and (6,200)
and then you do y2 -y1
x2-x1
you plug in the values
200-300
6-3 = -(100)/(3)
every 3 years the resale of a refrigerator decreases by 100 dollars.
its basically the rate that the price goes down for resale value of a refrigerator
Step-by-step explanation:
Let's take the points displayed on this graph:
(300, 3) (200, 6) and (100, 9).
Our first value in the points represents the amount of money for the resale value of a refrigerator, and the second value represents the number of years after the original purchase. So, as we can see, as the years increase, the value goes down $100 dollars every three years.
3 years after original purchase: $300
Increase years by three, value goes down by $100
6 years after original purchase: $200
The rate of change in this situation means that for every resale three years after the original purchase, the value will decrease by $100.

Solve each equation for y. Use the given values for x to find the values for y. Write answers as ordered pairs.
Answer:
1. x =-4 (-4,27)
x =0 (0,3)
x = 2 (2 , -9)
2. x = -1 (-1 , 3)
x = -2 (-2 , 2)
x = -3 ( -3, 1)
3. x = -3 (-3 , 13)
x = 1 (1 , 1)
x = -2 ( -2, 10)
4. x =2 (2 , 24)
x = 3 (3 , 30)
x = -2 (-2 , 0)
5.x = -3 (-3 , -2)
x = 2 (2 ,-12 )
x =4 (4 , -16)
6. x = -1 (-1 , -2)
x = 0 (0 , 2)
x = 2 (2 , 10)
7. x = -2 (-2 , -10)
x = 0 (0 , -14)
x = 3 (3 , -20)

What is the degree of 25 = 2.03 + 2.0 4x + 1
Answer:
Fraction: x = 2197/204
Decimal: 10.76960
Step-by-step explanation:
Switch Sides: 2.03 +2.04x + 1=25
Group Like Terms: 2.04x + 2.03 + 1 =25
Add The Numbers 2.03 + 1 = 3.03: 2.04x + 3.03 = 25
Multiply Both Sides By 100: 2.04 * 100 + 3.03 * 100 = 25 * 100
Clarify: 204x+303=2500
Subtract 303 From Both Sides: 204x + 303 - 303= 2500 - 303
Divide Both Sides By 204: 204x/ 204, 2197/204
Simplify: x = 2197/204

What do I do I don’t know the answer
Answer:
B) 114.511m^3
Step-by-step explanation:
Formula of a cylinder is πr^2 x h
r = radius (half of diameter)
h = height
Since it is 3/4 full you only do 3/4 of the height so- 0.75 x 9.60 which equals 7.2
Half of the diameter is 2.25. 2.25^2 = 5.0625.
The volume of the cylinder = 5.0625π x 7.2
By solving this, you will get approximately 114.511 m^3 as your answer.

what grade are u in that's easy lolll
Step-by-step explanation:
Factorise completely 8p-12pq
Answer: 4p(-3q+2)
Step-by-step explanation:
The hcf (highest common factor) of 8 and 12 is 4 so you would put a 4 in front of the bracket.
Then because it has p in both of the numbers you can put p at the front with the 4.
This looks like 4p so far.
After that, you would have to do -12/4=-3
So then because you don’t have a q at the front you would put it with the -3.
This looks like 4p(-3q) so far.
Then, you would have to do 8/4=2.
And as you have a p at the front, you don’t need one with the 2.
This would look like together as 4p(-3q+2)
I hope this helps it’s quite difficult to explain :)
