For the first equation, the answer is C) completing the square.
For the second equation, the answer is B) zero product property.
For the first equation, we can easily complete the square by finding half of b and squaring it; then we can take the square root of both sides and solve the equation.
For the second equation, since it is already factored, we use the zero product property to solve it.
Answer:
In the expression of 7xy, if x is negative, then y must also be negative for the product to be positive.

Answer:
this is unsolvable i think
Step-by-step explanation:
Answer:
5x + 2y = 9
Step-by-step explanation:
Find the slope of the line that is perpendicular to 2x - 5y = 7 :
m= 
Find the y - intercept of the function:
b = 
substitute m= and b = into y = mx + b :
y = 
+
y = 5x + 2y = 9
