X+y=6 is.....
solve for x=0... y=6
solve for y=0... x=6
intersect x-axis at (6,0)... calculate the slop: solve for x=1... 1+y=6... 6-1= 5 y=5
calculate the slope: a= y(x=1)-y(x=0)/1=-1
x+y=6
X equals 4. (this is supposed to be 20 characters long so i’m just typing randomly)
Answer:
D
Step-by-step explanation:
Factor the numerators/ denominators
10 - 5 = 5(2a - 1) ← common factor of 5
4a² - 1 = (2a - 1)(2a + 1) ← difference of squares
[ Change ÷ to × and turn second fraction upside down ]
=
× 
[ cancel the factor (2a - 1) on the numerator/denominator ] leaving
=
= 
72 bc 2 plus 6 is 8, 7 plus 10 is 18, 18 plus 14 is 32, 32 plus 18 is 50 and 50 plus 22 is 72!
C)
the answer should be 24a^-1b^10
