<span>3 x + 5 x + 4 - x +7 = 88
First, combine like terms.
7x + 11 = 88
Subtract 11 from both sides.
7x = 77
Divide both sides by 7.
x = 11</span>
Put the numbers in order
6,7,15,36,41,43,47,49
Q1 = (7 + 15) / 2 = 22/2 = 11 <== first quartile
Q2 = (36 + 41) / 2 = 77/2 = 38.5 <== median
Q3 = (43 + 47) / 2 = 90/2 = 45 <== third quartile
difference of largest value and median.....(49 - 38.5) = 10.5
Answer:
18
Step-by-step explanation:
RQ = (22+14)/2 = 36/2 = 18
Answer:
x-intercepts: -5 +/-
. y-intercept: 4
Step-by-step explanation:
For x-intercepts use the quadratic equation

Fill in your values:

And solve

For y-intercepts set x=0 and solve. In this case, setting x= 0 gives you y=4.
