1st thing you need to do is to graph the line y = x - 3 as a dashed line, since the it is just a less than symbol.  Once the line is graphed, we need to decide which side to shade.  I tend to use (0, 0) if at all possible.  We check 0 < 0 - 3

Since 0 is not less than -3 then we shade away from the point (0, 0).  That is how you find the answer.

First step is to graph the equality
y=x-3

In a graph of y=mx+b
m is the slope, and in this case, m=1, which means that y increases by one for each step in x=1.  This creates a line at 45 degrees from bottom left to top right, passing through the origin.

The b=-3 means the line has to be lowered from the origin by 3 units.
b is called the y-intercept, where the line cuts the y-axis (=-3).

So with the line drawn, we need to know the style of the line. 

If the inequality is a strict inequality (< or >), then the line is drawn dotted.
If the line is an inequality together with an equality ( &le; or &ge; or = ), then it is drawn solid.

Finally, an inequality has to be shaded on the side where the inequality is true.

Looking at the inequality, y<x-3  we can read immediately that the valid side is where y is small ("y is less"), so we shade the part below the line.

The finished graph is attached.

Gnoma [55]

Answer:

A. y-axis only

Step-by-step explanation:

We have the graph of  as given below.

It can be seen that  passes through the points (0,0), (4,0) and (6,0).

Also, the graph is plotted in the 1st and 2nd quadrant symmetrically along the y-axis.

Hence, the axis of symmetry of  is the y-axis only.

Viktor [21]

Answer:

\frac{3}{4}

Step-by-step explanation:

Total number of the students in the pep squad = 12 students

The number of the students wearing white shirts = 3 students

The number of the students wearing blue shirts = 6 students

Either white or blue shirts indicate that the students wearing white shirt or blue shirt.

Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students

So,

The fraction is:- \frac{9}{12}=\frac{3}{4}

Andre45 [30]

Answer:

A)1050

B)8050

Step-by-step explanation:

to find interest we use the formula A= P(1+rt) where P is the initial investment, r is the rate percent, and t is the time interval

for this question we have A=7000(1+3(5)) which gives 8,050 dollars which is the answer to part B

for part A we simply subtract the answer from B from the initial investment so 8050 - 7000 = 1050 made from interest
