Answer: <em>$90.00</em>
Step-by-step explanation:
<em>Take this equation </em>
<em>120(n)</em>
<em>n will equal 0.75 since it is 75% of the original price</em>
<em>120(0.75)</em>
<em>$90.00</em>
Answer:
(-2, -12), (0, 2), (2, 16), (4, 30)
Step-by-step explanation:
Input: -2
y = 7x + 2
y = 7(-2) + 2
y = -14 + 2
y = -12 (Output)
Input: 0
y = 7x + 2
y = 7(0) + 2
y = 0 + 2
y = 2 (Output)
Input : 2
y = 7x + 2
y = 7(2) + 2
y = 14 + 2
y = 16 (Output)
Input: 4
y = 7x + 2
y = 7(4) + 2
y = 28 + 2
y = 30 (Output)
Answer:
D. A cold, dry air mass interacts with a warm, moist air mass.
Step-by-step explanation:
Tornadoes are very scary and kind of cool to look at. They have a great scientific reason behind them which we can easily understand. First, a funnel cloud forms that reaches down to the ground (you probably have seen this in video as a cloud that is heavily densed and circling). Then , warm air rises, resulting in a decrease in air pressure and finally, a cold, dry air mass interacts with a warm, moist air mass.

_______________________________________________Method 1) Add "6" to EACH SIDE of the equation;
_______________________________________________ →
x − 6 + 6 = 2 + 6 ;
to get:

x = 8 ;
______________________________________________Multiply each side of the equation by "

______________________________________________Method 2)______________________________________________ x − 6 = 2 ; Solve for "x" ;
Add "6" to EACH SIDE of the equation;
_______________________________________________ →
x − 6 + 6 = 2 + 6 ;
to get:
→
x = 8 ;
______________________________________________Multiply each side of the equation by "3" ; to get rid of the "fraction" ;
→ 3 *
x = 8 * 3 ;
→
*
x = 8 * 3 ;
→
x = 8 * 3
→
x = 24 ;
→ 2x = 24 ;
→ Divide each side of the equation by "2" ; to isolate "x" on one side of the equation; & to solve for "x" :
2x / 2 = 24 / 2 ;
x = 12 .

___________________________________________NOTE: Variant: (in "Methods 2 & 3") :
___________________________________________At the point where:
