Answer:

1. Slope: -0.75x or -3/4x

Y-intercept: 7

Equation: -0.75x+7 or -3/4x-7

Remember -0.75 and -3/4 are the same!

2. Equation: 0.5x-3 or 1/2x-3

I used slope intercept form to solve. (y2-y1 over x2-x1) If you need more help comment below or send me a link!

Answer: (1) -3/4 (2) 7 (3) y = (-3/4)x + 7 (4) 1/2

Step-by-step explanation:

1) COUNT the number of spaces from one point to the other point.

from (0, 7) to (4, 4) is: down 3 and right 4 → m = -3/4

2) the y-intercept is where the line crosses the y-axis (when x = 0).

The line crosses the y-axis at (0, 7) → b = 7

3) Slope-Intercept form is y = mx + b

m = -3/4 and b = 7 → y = (-3/4)x + 7

4) COUNT the number of spaces from one point to the other point.

from (-2, -4) to (2, -2) is: up 2 and right 4 → m = 2/4 = 1/2 when simplified

Jeanette purchased a concert ticket on a web site. The original price of the ticket was $75. She used a coupon code to receive a

DedPeter [7]

Answer:

Jeanette’s ticket was less than the original price by 12 percent

Step-by-step explanation:

1. Let's calculate the 20% discount price Jeanette received:

75 - 0.2 * 75 = 75 - 15 = $ 60

The discounted price is $ 60

2. Let's calculate the 10% service fee to the discounted price:

60 + 0.1 * 60 = 60 + 6 = $ 66

The price including the service fee is $ 66

3. Finally, let's calculate the less percentage than the original price:

Let's use the Direct Rule of Three, this way:

Price Percentage

75 100

66 x

**************************

75x = 66 * 100

75x = 6,600

x = 6,600/75

x = 88

Less percentage = 100 - 88 = 12%

Jeanette’s ticket was less than the original price by 12 percent

Seth invested n dollars into an investment fund last year. After a period of one year, the value of his investment can be repres

Crank

Answer: A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

Here the initial amount = n

Final amount after 1 years = 0.84n

The total change in the initial amount = n - 0.84n = 0.16 n

$\text{ The percentage change in the initial amount} = \frac{\text{ the total change in initial amount}}{\text{ Initial amount}}\times 100$

= $\frac{0.16 n }{n} \times 100 = 16\%$

Thus, the amount is decreases by 16% in one year,

⇒ Option A is correct.

Answer:

0.99186 probability that the person will not die in the next year, and the correct option is A.

Step-by-step explanation:

Dying and not dying in that year are complementary events, that is, one of them will happen. This means that the sum of their probabilities is 100% = 1.

The probability of dying is:

$p = \frac{814}{100000} = 0.00814$

So the probability of not dying is given by:

$P = 1-0.00814 = 0.99186$

0.99186 probability that the person will not die in the next year, and the correct option is A.
