Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
2x+y=1
3x-y=4
-------------
y=3x-4
2x+3x-4=1
5x-4=1
5x=1+4
5x=5
x=5/5
x=1
y=3(1)-4=3-4=-1
Answer:
x² -7x -18
Step-by-step explanation:
In algebra, a binomial consists solely of a sum or subtraction of two monomials.
To solve the multiplication of two binomials we have to multiply term by term and then simplify common terms.
(x + 2)(x - 9) = x(x) + x(-9) +2(x) + 2(-9) = x² -9x + 2x -18 = x² -7x - 18
Answer:
The answer is "y > x-2 and y < x + 1"
Step-by-step explanation:
In the given question the last choice, that is "y > x-2 and y < x + 1" which can be defined in the following diagram.
11 hours bc 5 times 11 equals 55
