Step-by-step explanation:
f ( X) = ( 2X - I ) / 2X ^ 2 - 9X + 10
= 2X-1 ) /( 2X- 5 ) ( x - 2 )
set of zeros of denominator are :
2X- 5 . = 0
X= 5/2
or
X-2=0
X=2
set of zeros of denominator = { 5/2 ,2 }
domain = R - { 5/2,2 }
9 times 4 is $36 which is the price of the belt
$36 + $9 = 45
$45 + $ 10 = 55 so
<u>Keith had $55 dollars before he bought the shirt and the belt
</u>
Use PEMDAS
5) -6(12 -15) + 2^3
Parenthesis first: -6(-3) + 2^3
Exponent: -6(-3) + 8
Multiplication: 18 + 8
Addition: 26
26 is the final answer for #5
6) -50 / (-10) + (5 - 3)^4
Parenthesis: -50/-10 + (2)^4
Exponent: -50/-10 + 16
Division: 5 + 16
Addition: 21
21 is the final answer for #6
A.It is a function bc it has a exponential decrease
B.Exponential (its dividing my 3)
C. Decay or decrease
D. label the bottom 1,2,3 for weeks and the sides go up by 3 the graph should show a decrease in growth
