Answer:
Zero of the function;
f(x) = 0 at x = -1.333
Discontinuity;
x = 1
Step-by-step explanation:
To determine the zero of the function;
we simply graph the function as shown in the attachment below.
From the attachment, we can deduce that f(x) = 0 at x = -1.333
To determine the discontinuity or the undefined points of the function, we simply equate the denominator to 0 and solve for x;
x - 1 =0
x = 1
The function is therefore not defined at the point where x =1
Answer:
y = -1/2x
Step-by-step explanation:
The y - intercept is 0, because the point where the line touches the y - axis is y - value of 0
The slope is -1/2 because as it rises by -10, it runs by 20
Slope is rise/run which is -10/20 which simplifies to -1/2
y = mx + b
b = y - intercept
m = slope
y = -1/2x + 0 or y = -1/2x

Answer:
5x - 9 ≥ -28
Simplifying gives:
x ≥ -3.8
Step-by-step explanation:
Nine subtracted from the product of 5 and a number is at least -28
Let the number be x so;
5x - 9 ≥ -28
5x ≥ -28 + 9
5x ≥ -19
x ≥ -19/5
x ≥ -3.8
