Answer:
$252
Step-by-step explanation:
The price of the computer is $400
On saturday it is on sale for 30% off
30% of 400 or .3 x 400 = 120
400 - 120 = 280
Then, if she gets there before 9am there is an addition 10% off of the sale price (280)
So, 10% of 280 or .1 x 280 = 28
280 - 28 = 252
Hope this helps!
Answer: <em>0</em>
Step-by-step explanation:
<em>Simply the answer is </em><em>0</em><em> because anything multiplied by </em><em>0</em><em> will result in </em><em>0</em>
<em>4x(0) =</em><em> 0 </em>
Answer: x<−6
Step-by-step explanation:
If the value of x decreases, the value of y decreases
Answer:
See below
Step-by-step explanation:
Let's rewrite all three equations is standard slope-intercept format of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
Line a: -x+2y=3
2y = x + 3
y = (1/2)x + 3
Line b: -6x=3y-1
-3y = 6x - 1
y = -2x + (1/3)
Line c: 4x-8y=5
-8y = -4x + 5
y = (1/2)x - (5/8)
Parallel lines have the same slope (m). Perpendicular lines have slopes that are the negative inverse (-1/m)of each other.
Slopes, m, for the lines are;
The negative inverse of (1/2) is -2.
Lines a and c are parallel (same slope)
Line b is perpendicular since it's slope is the negative inverse of both a and b (-1/(1/2)) = -2
