Answer:
2x^2-6x-4
Step-by-step explanation:
(7x2 + 4x - 9)
-(5x2 + 10x - 5)
=
7x^2-5x^2=2x^2
4x-10x=-6x
-9-(-5)=-4
thus, your answer is 2x^2-6x-4
4 will go into 25 six times
that leaves 1.20. 4 goes into 1.20 .3 times
6+.3 is 6.3
The least common multiple is the smallest multiple of the given numbers that is a common multiple for all the numbers being compared.
We have to divide the numbers by numbers that are divisible
15,12
Divide both by 3 -15/3 =5. 12/3 =4
5 and 4 aren’t divisible by any common numbers, we take them as it is
L.C.M = 3*4*5 = 60
Answer is 60
Answer:
2y
Step-by-step explanation:
Simplifying
21x + -42y = 0
Solving
21x + -42y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '42y' to each side of the equation.
21x + -42y + 42y = 0 + 42y
Combine like terms: -42y + 42y = 0
21x + 0 = 0 + 42y
21x = 0 + 42y
Remove the zero:
21x = 42y
Divide each side by '21'.
x = 2y
Simplifying
x = 2y
The slope/ gradient of the line is -2/3 or answer c
