Answer: B 2x
1/2x-3+3/2x+3
X= 6
Explanation:
y=9 so rewrite the equation like this:
5x-2(9)=12
Multiply -2 by 9:
5x-18=12
Cancel out the -18:
5x-18=12
+18 +18
5x=30
Divide both numbers by 5:
5x/5 = 30/5
As an answer, you will get x=6:
Hope this helped:)
Answer:
Subtract 3 x 3 x from both sides of the inequality. Divide each term by - 2 − 2 and simplify. Tap for more steps... Divide each term in - 2 y < 10 - 3 x − 2 y < 10 − 3 x by - 2 − 2. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign

Answer:
t = 2.5 s
Step-by-step explanation:
h(t)=-16t^2 +80t+96
height will be greatest when the derivative (velocity) is zero
h'(t) = v(t) = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32 = 2.5 s
notice that 0 = -32t + 80 is just a version of the kinematic equation
v = u + at
where v is final velocity at the top of the arc or zero
u is the initial upward velocity or 80 ft/s
a is gravity or -32 ft/s²
t is time in seconds
I think what you had was correct if you are talking about 17
