Hello,
y=k(x+3/2)²-25/2
and -8=k*9/4-25/2==>9/4k=9/2==>k=9/2*4/9=2
y=2(x+3/2)²-25/2
x- intercepts:
y=0=2(x+3*2)²-25/2
==>(x+3/2)²=25/4
==>x=-3/2-5/2 or x=-3/2+5/2
==>x=-4 or x=1
(-4,0) and (1,0) are x intercepts
Answer no choice!
On the communicative property, the numbers swith their places, so the answer would be A)
So I found the data for both sets of numbers.
It’ll go the first number is for set one, second number is for set two
Mean: 3, 2.909
Median: 3, 3
Quart: Q1- 2,1
Q2- 3,3
Q3- 4,5
Range: 6,5
SD: 1.73, 1.86
Mode: 3, 1
Hopefully this helps !
1st hour 350 purched tickets @ $17.50 each = $6,125
the second hour 20% more people purchased tickets than the first hour - 350 x 20%=70 more than 1st hour.so 70 x $17.50=$1,225 so total sales is $6,125 + 1,225=$7350
Answer:
-2
Step-by-step explanation:
5x – 15 > 10 + 20x
Subtract 5x from each side
5x – 15-5x > 10 + 20x-5x
-15 > 10+15x
Subtract 10 from each side
-15-10 >15x
-25 > 15x
Divide each side by 15
-25/15 > x
-5/3 > x
X must be less than -1 2/3
The only value that is less than -1 2/3 is -2
