Answer:
the value of x equals to 20 thats is solution okay
<h3>
Answer: 25% decrease</h3>
=======================================================
Work Shown:
A = old value = 360
B = new value = 270
C = percent change
C = (B-A)/A
C = (270-360)/360
C = -90/360
C = -0.25
C = -25%
The negative C value indicates we have a percent decrease.
Note how 25% of 360 = 0.25*360 = 90, meaning that the price has dropped by 90 galleons. And also note that 360-270 = 90 is that same figure of 90. This helps confirm the answer.
Answer:
Another point is (3,1) and the vertex is (0,0)
Step-by-step explanation:
The vertex is still (0,0) since the parabola has only been stretched some way and not shifted from the parent function f(x)=x^2.
Enter in any x you like like 3 (I chose 3 because I see I'm going to multiply by 1/3). Anyways
g(3)=(1/3*3)^2=(1)^2=1 so another point on the parabola is (3,1)... Now just use the fact that all parabolas are symmetrical to graph it.
X<12
<span>5(x+5)<85 </span>
<span>5(x + 5)/5 < 85/5 </span>
<span>x + 5 < 17 </span>
<span>x + 5 - 5 < 17 - 5</span>
