Answer & Step-by-step explanation:
Factors of a number are the number(s) whose product ie multiplication gives the number. Prime factorisation is finding 'prime' factors of numbers, ie the numbers which dont have a factor further - other than themselves & 1.
Example : 6 = 2 x 3, so 2 & 3 are factors of 6. Also, 2 & 3 are prime factors, as they dont have further multiplication factors, other than themselves (2 & 3 respectively) & 1. So this can be an illustrative case of prime factorisation of 6.

Answer:
Twenty-one is a factor of the number because both 3 and 7 are prime factors.
Step-by-step explanation:
Given number is,
3^2\times 5^3\times 73
2
×5
3
×7
=3\times 3\times 5\times 5\times 5\times 7=3×3×5×5×5×7
Where, 3, 5 and 7 are prime numbers ( only divisible by 1 and itself ),
⇒ Both 3 and 7 are prime factors of the given number,
⇒ 21 is a factor of the given number.
Thus, first option is correct.
⇒ Second option is incorrect.
Now, 5 is factor of the given number but 2 is not,
⇒ 10 is not a factor of the given number,
⇒ 90 is not a factor of the given number,
⇒ Third option is incorrect.
Suppose 90 is divisible by 7,
⇒ 90 = 7a
Where a is any whole number,
⇒ 7=\frac{90}{a}7=
a
90
3^2\times 5^3\times 7=3^2\times 5^3\times \frac{90}{a}3
2
×5
3
×7=3
2
×5
3
×
a
90
Since, 90 could be a factor of this number, if a = 3 or 5 or their multiple,
For the other values of a, 90 can not be the factor,
Hence, there is no effect of divisibility of 90 by 7 on having 90 as a factor of the given number,
⇒ Fourth option is incorrect.

10/1 math work again plz help
Answer:
1. y = -0.75x + 2
2. y = -1.8x - 7
3. y = -3x + 3
4. y = -11/7x + 56
5. y = -0.6x + 3
6. y = -2x - 14
7. y = 14x + 7
8. y = 2/8x - 4/3
9. y = x - 6
10. y = -1/3x + 4
Step-by-step explanation:
Question 1
3x + 4y = 8
4y = -3x + 8
y = -0.75x + 2
Question 2
9x + 35 = -5y
5y = -9x - 35
y = -1.8x - 7
Question 3
2y - 6 = -6x
2y = -6x + 6
y = -3x + 3
Question 4
-11x - 7y = -56
7y = -11x + 56
y = -11/7x + 56
Question 5
5y/3 = -(x - 5)
5y = -3(x - 5)
5y = -3x + 15
y = -0.6x + 3
Question 6
-2(2x + y) = 28
-4x - 2y = 28
2y = -4x - 28
y = -2x - 14
Question 7
-14x + y = 7
y = 14x + 7
Question 8
12y = (8x - 48)/3
36y = 8x - 48
y = 2/8x - 4/3
Question 9
(3x - 3y)/2 = 9
3x - 3y = 18
3y = 3x - 18
y = x - 6
Question 10
2x/3 + 4(y - 2) = 0
2x/3 + 2y - 8 = 0
2y - 8 = -2x/3
3(2y - 8) = -2x
6y - 24 = -2x
6y = -2x + 24
y = -1/3x + 4

hi!! here is your answer
Answer:
30
Step-by-step explanation:
4x + x + 30 = 180 (co interior angles are equal)
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 150/5

5(x – 2) = 30 what is x
Answer:
-10
Step-by-step explanation:
Answer:
x=8

Distribute:
5x - 10 =30
Add 10 to both sides:
5x = 40
Divide
x=8
Check your work:
5(8 - 2) =30
5(6) =30
5 * 6=30
30=30!
Final answer: x=8

in how many year will rs 8000 amount to rs 13824 at 20% per annum interest compounded annually? please please help me out
Answer :-
3 yearsstep by step explanation:-
Let the time be x
principal = rs 8000
Amount = rs 13824
rate = 20% p.a
A = P(1+r/100)^n
13824 = 8000 ( 1 + 20/100)^n
=> 13824/8000 = (120/100)^n
=> 13824/8000 = (24/20)^n
=> (24/20)³ = (24/20)^n
=> 3 = n
=> n = 3 years

The graph of a linear function has a y-intercept of 5 and passes through the point (2, 5). What is the slope of the graph of the function?
Answer:
Step-by-step explanation:2/5
The slope of the graph of function is 0
From the equation of the slope-intercept form of an equation of a straight line,
We have
y = mx +c
Where m is the slope
and c is the y-intercept
From the given information,
c = 5
and
The line passes through the point (2, 5)
∴ x = 2 and y = 5
Putting these values into the equation, we get
5 = m(2) + 5
5 = 2m + 5
5-5 = 2m
0 = 2m
∴ m = 0 ÷ 2
m = 0
Hence, the slope of the graph of function is 0
