The answer is the temperature goes down 2.8° every hour and the expression is x=-11.2/4 because 4 is how many hours between 6pm and 10pm and its -11.2 because that was how much the temperature dropped from 6pm to 10pm
You have to get from $30 to $21.75
21.75/30=0.725 x 100= 72.5% of the original price
Answer:
5x-4y+4
Step-by-step explanation:
3x-4y-2+2x+6
Gathers like terms together:
3x+2x= 5x
-4y= -4y
-2+6= 4
Put it together:
5x-4y+4
Hello!
You solve this algebraically
6(3 - 2x) = 54
distribute the 6
18 - 12x = 54
Subtract 18 from both sides
-12x = 36
Divide both sides by -12
x = -3
The answer is -3
Hope this helps!
Y = -4x + 2
3x + 2y = 6 (or in y-intercept form y=-3/2x + 3)
2x - y = 7 equals y = 2x -7 in y-intercept form. This means that the line has a positive slope and therefore goes upwards. This cannot be a potential equation because the line shown is clearly pointing downwards.
y=5 indicates that the line is a horizontal line that neither points upwards or downwards. This cannot be a potential equation because the line is pointing downwards.
The only possible equations left are y= -4x + 2 and 3x + 2y = 6, both of which graph a line pointing downwards because their slopes are negative. Hope this helps!
