A laptop normally costs $660

Mathematics
1 answer:
rewona [7]3 years ago
8 0
Answer:
$360.00

Explanation:
Turn 45% into a decimal
45%= .45
Then we multiply the 660 x .45
660 x .45=297.00
Then we subtract $660-297
$660-297=363

So the answer is $363.00

Sorry my explanation is bad

What is the first step when rewriting y=6x^2+18x+14 in the form y=a(x-h)^2+k?
Grace [21]
<h3>Answer:</h3>

Factor 6 from the first two terms.

<h3>Step-by-step explanation:</h3>

By factoring out "a", you can better see what "h" needs to be.

  1. y = 6(x^2 +3x) +14 . . . . 6 factored from first 2 terms
  2. add the square of half the x-coefficient inside parentheses; add the opposite outside: y = 6(x^2 +3x +2.25) +14 -6(2.25)
  3. rewrite as a square; combine the constants: y = 6(x+1.5)^2 +0.5

Which is an equation in point-slope form for the given point and slope point (8 -4) slope 5/6
Alina [70]

If you want to say thank you, click the "Thanks" button and select the answer "The Brainliest!" We appreciate it!

Step-by-step explanation:

Point slope form: (y−y1) = m (x−x1), where (x1,y1) is the point, and m is the slope.

(y- (-4)) = (5/6)*(x - 8)

(y + 4) = (5/6)*(x - 8)

If you want in standard form

(y + 4) = (5/6)*x - (5/6)*8

y = (5/6) x - (5/6)*8 - 4

y = (5/6)x - (16/6)


Answer:

(y + 4) = (5/6)*(x - 8)
