Answer:

x < 3

Step-by-step explanation:

The standard linear equation of a <u>vertical line</u> with an undefined slope is <em>x </em>=<em> a</em>, where "a" represents the <u><em>x-intercept</em></u> of the graph.  Vertical lines have an undefined slope because it doesn't have any horizontal change.

The given graph represents the graph of a <u>vertical line</u>, whose x-intercept occurs at point (3, 0). Since the graph has a <u>dashed boundary line</u>, then it means that the linear inequality symbol used to represent the graph is "<," which implies that the endpoint, x = 3, is not included as part of the solution. Additionally, since the shaded half-plane region is towards the left-hand side of the boundary line, it means that the solution must less than 3.

Therefore, the linear equation that represents the given graph is x < 3.

Martha has $20 to spend on a t-shirt. She has a coupon for 20% off. The t-shirt regularly sells for $22.50 plus 10% sales tax.
rodikova [14]

Answer:

1 and 3

Step-by-step explanation:

Step 1 is clearly elaborated.  Tax is impliedd on the discounted price.

In step 3, the steps of deductions are skipped.

Like 1 + 10% = 110% and 1 - 20% = 80%

Step 2 is simply wrong. Because the percentages are implied on different values.
