How is a 15% discount similar to a 15% decrease? How is 8% sales tax like an 8% increase?

1 answer:

6 0

It is important to remember that a discount is the same as a decrease and a sales tax means an increase. If you remember this, you will easily know how to go about solving the mathematical questions.
A 15% discount is similar to a 15% decrease because a discount means a decrease in price and serves the purpose of a decrease.
An 8% sales tax is like an increase because it means that it is an 8% increase over the original price.

Estimate the difference 7 3/4-2/25 Show your work.

crimeas [40]

Answer: 7 3/4 - 2/25 = 767/100 = 7 67/100 = 7.67

Step-by-step explanation:

Conversion a mixed number 7 3/4

to a improper fraction: 7 3/4 = 7 3/4 = 7 · 4 + 3/4= 28 + 3/4 = 31/4

To find a new numerator:

a) Multiply the whole number 7 by the denominator 4. Whole number 7 equally 7 * 4/4 = 28/4

b) Add the answer from previous step 28 to the numerator 3. New numerator is 28 + 3 = 31

c) Write a previous answer (new numerator 31) over the denominator 4.

Seven and three quarters is thirty-one quarters

Subtract: 31/4 - 2/25= 31 · 25/4 · 25 - 2 · 4/25 · 4 = 775/100 - 8/100 = 775 - 8/

100 = 767/100

What is the answer to the main problem

Sholpan [36]

Answer:

x-int: (3, 0)

y-int: (0, -1.5)

Step-by-step explanation:

x-intercept is the x-value when y = 0

y-intercept is the y-value when x = 0

Step 1: Find x-intercept

0 = (x - 3)/2

0 = x - 3

x = 3

(3, 0)

Step 2: Find y-intercept

y = (0 - 3)/2

y = -3/2

(0, -1.5)

Answer:

quadratic function
y-intercept: y = -6
x-intercepts: x = 2 and x = 6
y = 2, x = 4
y ≥ 0

Step-by-step explanation:

The given graph is a parabola and so it a quadratic function.

The y-intercept is the point at which the curve crosses the y-axis.

From inspection of the graph, this is when y = -6.

The x-intercepts are the points at which the curve crosses the x-axis.

From inspection of the graph, the x-intercepts are x = 2 and x = 6.

The vertex is the turning point of the graph, so the minimum point of a parabola that opens upwards, and the maximum point of a parabola that opens downwards.

From inspection of the graph, the vertex is at (4, 2), so the greatest value of y is y = 2, and it occurs when x = 4.

The curve is above the x-axis between the interval x = 2 and x = 6.

Therefore, the function value is equal to zero or positive in this interval.

So the function value in the given interval is y ≥ 0.
