Answer:
E. All values of x are solutions
Step-by-step explanation:
- -15x + 4 ≤ 109
- -6x + 70 > -2
Solve for x in the first equation. Subtract 4 from both sides.
-15x ≤ 105
Divide both sides by -15. Since this is a negative number the sign will flip.
x ≥ -7
Solve for x in the second equation. Subtract 70 from both sides.
-6x > -72
Divide both sides by -6; the sign flips.
x < 12
Since this is an OR problem we won't be combining the two solutions for x. Therefore you would graph x ≥ -7 and x < 12 separately.
The graph would look like this: (image attached)
Since the two lines cross pathways to cover the entire number line, this means that there are infinite values of x.
The answer should be E.
Answer:
Plot these points and connect with a line: (4, 5) and (-1, -5)
Step-by-step explanation:
For the values of x needed, just put it into the formula.
The values of x needed are: -1 to 4.
Input any values from -1 to 4.
y = 2*-1 - 3
y = -2 -3
y = -5
y = 2*4 -3
y = 8-3
y = 5
Plot these points and connect with a line: (4, 5) and (-1, -5)

Answer:
Definition: Standard deviation is the measure of dispersion of a set of data from its mean. It measures the absolute variability of a distribution; the higher the dispersion or variability, the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean.
