Answer:
12 x ≤ 48
Step-by-step explanation:
This inequality must have two sides, one that shows the expenditure Mary will do in function on the number of shirts (x) and other that shows the maximum money she can spend (48).
Her expenditure will depend on the shirts purchased (x) and as each shirt costs $12 the expenditure will be 12x. So, this expenditure MUST be equal or less to the maximum she can pay: $48.
The inequality will be:
12 x ≤ 48
This is the first of the options posted. From the others, none of them work.
Answer:
Alright just add fractions, find the LCD and then combine
53 Hope this helps. :)
Step-by-step explanation:
Please enclose fractions such as 8/7 inside parentheses:
<span>(8/7)x^3+x^4+6x+1
Next, arrange these four terms in order of power of x:
</span>x^4 + (8/7)x^3+ 6x+1 This is the standard form you wanted.
Answer:
Step-by-step explanation:
cos x cos (3x)+sinx sin (3x)=0
cos (x-3x)=0
cos(-2x)=0
cos 2x=0=cos (2n+1)π/2
where n=0,1,2,3∞∞∞∞
2x=(2n+1)π/2
x=(2n+1)π/4
put n=0,1,2,3
x=π/4,3π/4,5π/4,7π/4
