Answer:
36=x^2+5x
x^2+5x-36=0
(x+9)(x-4)
x= 4
x= -9
The Answer can be 4 or -9, see which option you have.
Step-by-step explanation:
Answer:
y =-5x + 7
Step-by-step explanation:
y = -5x + 4
Slope = -5
Parallel lines have same slope
Slope of the parallel line to this line = -5
(1 , 2)
y -y1 =m(x - x1)
y - 2 = -5(x - 1)
y -2 = -5x + 5
y = -5x + 5 + 2
y = -5x + 7
Answer:
Answer J
Step-by-step explanation:
To simplify the concept, we can change the inequality to y+3 >= 5. The variable "y" is "-1/2(x)" We know that y must be greater than or equal to "two." The only way this is possible is if x itself is equal to or less than -4.
