Answer:
x= -8 , x=5
Step-by-step explanation:
2x^2+6x-80=0
x^2+3x-40=0
look for 2 numbers that their:
sum = 3
product = -40
(x+8)(x-5)=0
thus
x= -8 , x=5 (ANS)
Answer:
20/48
Step-by-step explanation:
Answer:
20a³
Step-by-step explanation:
Simply multiply:
-5(-4) = 20
-a(-a)(a) = a²(a) = a³
20a³

Answer:
y = -4x +2
Step-by-step explanation:
The equation you're writing is in slope-intercept form. The coefficient of x is the slope, which is the "rise"/"run" of the line.
Here, to get from the left point to the right point, you must go down 4 units (rise=-4) and 1 unit to the right (run=1). So, the slope is ...
m = rise/run = -4/1 = -4
The constant in the equation is the y-intercept: the y-coordinate of the point where the line crosses the y-axis. That point is marked as (0, 2), so its y-coordinate is 2.
The equation for the line is ...
y = -4x +2
