Answer:
a^3+3a^2b+3a^2c+3ab^2+3ac^2+6abc+b^3+c^3+3bc^2+3b^2c if you want it expand
(a+b+c)(a+b+c)(a+b+c) is equal to (a+b+c)^3
Answer:
x ≥ 7
Step-by-step explanation:
"Is at least" means the same as "is greater than or equal to". Then "x is greater than or equal to 7" is expressed in symbols as ...
x ≥ 7
system of equations (1,1)
put value of these x and y in equations
(x , y) = ( 1,1)
so this solution not satisfied equation 1
11( 1) + 3 (1) = 18
so 11 + 3 = 18
15 = 18 ( Left side not equal to right side )
(1,1) is not solution for 11x+ 3y=18
2. 4x+y = 5
put values (1,1)
4(1) + (1) = 5
5 = 5 { left side = right side )
so (1,1) is solution for 4x +y=5
Two equations you can use in point slope form are:
y-6 = -3(x-1)
y-3 = -3(x-2)
Hope this helps✨❤️
