One day, the hours without daylight in a particular city was 17 3/4 hours. What was the number of hours of daylight? PLS help me ASAP!

Answers

Answer:

6 ¼ hours of Daylight

Step-by-step explanation:

a day = 24 hours
you know that there was 17 ¾ hours of no day light
17 ¾ = 17.75
24 - 17.75 = Daylight hours
daylight hours = 6.25

consider the function f(x) = x2 2x – 15. what are the x-intercepts of the function? left-most x-intercept: ( , 0) right-most x-intercept: ( , 0)

Answers

x^2 + 2x - 15 = 0
(x - 3)(x + 5) = 0
x = 3 or x = -5
left-most x-intercept: (-5, 0)
right-most x-intercept: (3, 0)

Final answer:

To find the x-intercepts of the quadratic function f(x) = x^2 + 2x - 15, we factor the equation to (x + 5)(x - 3) = 0, resulting in x-intercepts at (-5, 0) and (3, 0).

Explanation:

The student is asking how to find the x-intercepts of the quadratic function f(x) = x2 + 2x - 15. An x-intercept is a point where the graph of the function crosses the x-axis, which occurs when f(x) = 0. To find the x-intercepts, we need to solve the quadratic equation x2 + 2x - 15 = 0. This can be done by factoring the quadratic, applying the quadratic formula, or completing the square. In this case, the equation factors to (x + 5)(x - 3) = 0, which gives the solutions x = -5 and x = 3. Therefore, the left-most x-intercept is (-5, 0), and the right-most x-intercept is (3, 0).

How to rewrite -7x + 5y = -3 in standard form

Answers

Answer:

7x - 5y = 3

Step-by-step explanation:

The Standard Form formula is Ax + By = C, however, technically A should not be negative, and since the original is already written in an usually accepted version of Standard Form, I would assume you would just want to multiply the entire equation by -1 making the A a positive number.

Natalie charges $1490 per month to rent each of her three rental houses. Natalie must pay $5850 in maintenance cots per house per year. If all three houses are occupied, how much money will Natalie earn over seven years?

Answers

3(1490) = 4470 per month for rent she collects...4470(12) = 53640 per yr
3(5850) = 17550 per year she pays in maintenance cost

over 7 yrs...
53640(7) - 17550(7) = 375480 - 122850 = 252630 <== what she earned
