drek231 [11]

Answer: OPTION C.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Notice that the line of f(x) is dashed. This means that the symbol of the inequality must be or >.

Since the shaded region A is above the line, the symbol is >

Observe that its y-intercept is:

b=3

The line of g(x) is solid. This means that the symbol of the inequality must be \leq or \geq.

Since the shaded region B is below the line, the symbol is\leq .

Observe that its y-intercept is:

b=-2.

Based on this, we can conclude that the graph represents the following System of Inequalities:

\left \{ {{y\leq 2x -2} \atop {y >-x + 3}} \right.

PLEASE HELP
nata0808 [166]

Answer: the first option is the correct answer.

Step-by-step explanation:

Martin runs 3/4 mile three days a week. We would assume that he runs a total of 3/4 miles in three days of each week.

In four weeks the number of days that he runs would be

3 × 4 = 12 days

Since he runs 3/4 miles in 3 days, the number of miles that he would run in 12 days would be

3/4 × 12 = 9 miles

He would run 9 miles in four weeks
