Answer:
1.7 xy +2yx + 4xy +5 =13xy+5
2.5x^2 y+3xy^2+x^2 y==6x2y+3xy2
Step-by-step explanation:
If the graph is a straight line, then it is linear. And If the y values is the same. The power of each, x and y in the equation is one.
Hello here is a solution :
<span>f(x) = x3 − 121x = x(x²-121) = x (x² -11²)
</span>f(x) = x (x+11)(x-11)
Answer:
x > 2
y ≥ 2
x + y ≤ 8
Step-by-step explanation:
Here, we want to write a system of equations according to the given variables
More than means, greater than
since x is the variable we want to use;
x > 2
At least 2 hours means greater than or equal to 2
That is mathematically represented as;
y ≥ 2
At most means less than or equal to
So;
x + y ≤ 8
