Answer:
Step-by-step explanation:
5x-1=49
5x=50
X=50/5
X=10
2x+5=1
2x=-4
X= -4/2=-2
1-x=10
-x=10+1
X= -11
9x - 3 = 15
9x =12
X =12 /9
X=4/3=1.33
9-6x= 17
-6x= 8
X=8/-6
X=-1.33
Answer: 108
Step-by-step explanation:
144% of 75 =108
Explanation:
144% of 75 means
144% × 75
144/100 × 75
= 144 × 3/4 = 36 × 3 = 108
Answer: a=x, then polynomial is zero.
a = x - 1/(x^2+x-1), then polynomial is one, but we have to note (x^2+x-1) != 0.
Step-by-step explanation:
The polynomial product is identically zero when a = x, since factor (x-a) becomes zero. Another way for a polynomial to not contain x is if it is a constant not zero. For example,
(x-a) = 1/(x^2+x-1)
a = x - 1/(x^2+x-1)
Substitute a = x - 1/(x^2+x-1) into
(x^2+x-1)(x-a) = (x^2+x-1)/(x^2+x-1) = 1.
IQR = Q3 - Q1
Q1 is where the box starts and Q3 is where the box ends.
So in this case:
Q1 = 25
Q3 = 33
Subtract:
33 - 25 = 8
So the IQR is 8.
