Y = 2x² + 30x + 200
y = 2(x² + 15x + 100)
x² = x*x
100 ⇒ 1 x 100 ; 2 x 50 ; 4 x 25 ; 5 x 20 ; 10 x 10
200 = 2x² + 30x + 200
0 = 2x² + 30x + 200 - 200
0 = 2x² + 30x + 0
0 = 2(x² + 15x + ?)
<span>−5 ≤ x ≤ 20</span>
The solution of the inequality is x ≥ 1.
Solution:
Given inequality:
To find the solution of the inequality:
Subtract 8 from both sides.
Divide by 3 on both sides.
On simplifying this, we get
The solution of the inequality is x ≥ 1.
The graph of the solution is attached below.
Answer: 7.5 gallons
Step-by-step explanation:
300 divided by 40 is 7.5
Mark me as brainliest if this helps!
2014⇒2277 athletes
2013⇒2070 athletes.
x=number of athletes in 2013
110% of x=2277
(110/100x=2277
x=(2277*100)/110=2070
2012⇒2300 athletes.
x=number of athletes in 2012
90% of x=2070
(90/100)x=2070
x=(2070*100)/90=2300
Answer: 2300 athletes were signed up for a spring sport in 2012.
Answer:
63 in.3 that's what I got so I hope it's right
