Answer:
78
Step-by-step explanation:
plug in -3 as x
6(2(-3)^2-5)
6(2(9)-5)
6(18-5)
6(13)
78
Sorry, But I had to put my answer as a screenshot because Brainly thought it was a link.
Substitute y = 15x to the equation y = 25 + 12.5x:
15x = 25 + 12.5x <em>subtract 12.5x from both sides</em>
2.5x = 25 <em>divide both sides by 2.5</em>
x = 10
Substitute the value of x to the equation y = 15x:
y = (15)(10)
y = 150
<h3>
Answer: x = 10 and y = 150</h3>
The distance formula is
D = square root of [ (difference in 'y')² + (difference in 'x')² ]
If the two points are on the same vertical line, the difference in 'x' is zero.
If they're on the same horizontal line, then their difference in 'y' is zero.
Either way, one of the terms in the distance formula is zero. It goes away,
and the distance formula becomes ...
D = square root of [ (difference in one coordinate)² ] .
That's just the square root of something squared, so it's only
D = (difference in one coordinate)
without going through all the squaring and rooting business.
Answer:
4 songs: $3.96 8 songs: $7.92
Step-by-step explanation:
- Divide to find out how much it costs for 1 song.
5.94 / 6 = 0.99 <u>Each song costs $0.99</u>
- Now multiply $0.99 by (number of songs)
- 0.99 x 4 = 3.96
- 0.99 x 8 = 7.92
