So for these problems you just need to get all x values on one side of the equal sign. Since this has just an x and not other x values we can leave the x there on the left. Now subtract 5 on both sides to get rid of the 5 on left side of the equals sign. Subtract 5 on the right side too because anything that you do on the left side, you do on the right side as well. It should look like this now:
Hope this helps!
Answer:
x=13
Step-by-step explanation:
2x+9=35
2x=35-9
2x=26
x=26/2
x=13
Answer:
136% = 1.36
Step-by-step explanation:
(950-700)/700
=0.3571 (0.36)
Then you have to plus one
0.36+1
=136% or 1.36
Answer:
x₁ > x₂
Step-by-step explanation:
Both actions imply a parable trajectories, since both are projectile shot cases.
Let´s call x₁ maximum distance in the first case
The maximum height is just in the middle of the curve, therefore x₁ the maximum horizontal distance is equal to 60 feet.
In the second case, the parable curve is modeled by:
y = x₂*( 0.08 - 0.002x₂) or y = 0.08*x₂ - 0.002*x₂²
A second degree equation, solving for x₂ and dismissing the value x₂ = 0
we get:
y = 0 ⇒ x₂*( 0.08 - 0.002x₂) = 0 x₂ = 0
And 0,08 - 0.002*x₂ = 0
- 0.002*x₂ = - 0.08
x₂ = 0.08/0.002
x₂ = 40 f
Then x₁ > x₂
