Hey :)
x= -12
Use the distributive property to multiply −4 by 2x+13
−8x−52=3x+80
Subtract 3x from both sides
−8x−52−3x=80
Combine −8x and −3x to get −11x
−11x−52=80
Add 52 to both sides
−11x=80+52
Add 80 and 52 to get 132
−11x=132
Divide both sides by −11
x= 132/-11
Divide 132 by −11 to get −12
x=−12
Hope this helps :)
On the x column, you would write 1, 2, 3, 4, and so on. Then, in the y box, you plug in that number into the equation. Write your answer in the y column.
For example, if x = 1, then 1^2 + 2 - 8 = - 5.
If x = 1, y= -5
I really don’t understand
The first question would be distance from the start, as it is steadily going up as time goes on.
The second question would be distance from the end, as it is steadily going down as time goes on.
The third question would be speed, as the speed is staying stable as shown by the straight lines seen within the distance from start/end graphs being linear lines.
Time = 11/2 = 5 1/2
Road = 4 1/2 miles
Speed = 5 1/2 : 4 1/2 = 1 2/9 <------------answer
