Answer:
B
Step-by-step explanation:
y-intercept is positive 5 so that eliminates answer choices A and C
to decide between B and D, select a point in the solution area; for example, (0, 0). Plug these values into B and D and see which one it is true for
B) 0 ≥ -3(0)-5
Is 0 ≥ -5 Yes
D) 0 ≤ -3(0)-5
Is 0 ≤ -5 No

Answer:
y=mx+b
Step-by-step explanation:
Y is just y
m is the slope
x is the x point
b is the y intercept
300 with a remainder of 10
3 0 0
1 4 | 4 2 1 0
4 2
1 0
Therefore, 4210 / 14 = 300 with a remainder of 10.
300 with a remainder of 10
Answer:
x1 = -b+√b²-4ac/2a and;
x2 = -b-√b²-4ac/2a
Step-by-step explanation:
Given the quadratic expression ax^2+bx+c = 0
The general formula for finding x is expressed as;
x = -b±√b²-4ac/2a
Hence the two roots on separaing are;
x1 = -b+√b²-4ac/2a and;
x2 = -b-√b²-4ac/2a
