How do you find the total cost of a $12.95 DVD after the tax is added?

Mathematics
1 answer:
sammy [17]2 years ago
3 0

Answer:

D

Step-by-step explanation:

100%->12.95

6%->0.81 (estimated)

hence use 12.95 + 0.81 to find the total cost including tax

note: this answer would not be accurate as an estimated number cannot be used for further calculation

What would the graph look like for ^
Jet001 [13]

Answer: The correct option is the first one.

Step-by-step explanation:

Let's define how to interpret each symbol:

x < a  (x is strictly smaller than a, we graph this with an open circle at a, and an arrow to the left of a)

x > a (x is strictly larger than a, we graph this with an open circle at a, and an arrow to the right of a)

x ≥ a (x is larger than or equal to a, we graph this with a closed circle at a, and an arrow to the right of a)

x ≤ a (x is smaller than or equal to a, we graph this with a closed circle at a, and an arrow to the left of a)

In this case, we have the inequality:

x ≤ 15

Then to graph this we need a closed circle at 15, and an arrow to the left. The correct option is the first one.

Find the slope of a line perpendicular to 3x + 5y = 15.
Zielflug [23.3K]

Answer:

B)5/3

Step-by-step explanation:

"3x + 5y = 15."

Rewrite in slope-intercept form.

The slope-intercept form is  

y=mx+b

where  m is the slope and  b  is the y-intercept.

y=mx+b

Subtract  3x  from both sides of the equation.

5y=15−3x

Divide each term by  "5"  and simplify.

5y/5=15/5−3x/5

"5" and "5" cancel each other out

Divide  15  by  5

y=3-3x/5

Reorder  3  and  −3x/5

y=-3x/5+3

Rewrite in slope-intercept form.

y=−3/5x+3

Slope:-3/5

The equation of a perpendicular line to  y=−3x/5+3  must have a slope that is the negative reciprocal of the original slope.

<em>m</em>perpendicular=−1/(−3/5)

Simplify the result.

mperpendicular=5/3

hope this helps!
