(x,y) or
(x,f(x))
so just plug the first value in and see if yo get the 2nd value
A. when x=-2, then is f(x)=48?
remember, x^-m=1/(x^m)
3(1/4)^-2=3/((1/4)^2)=3/(1/16)=3*16=48
true
B. x^0=1
so 3(1/4)^0=3(1)=3
true
C. when x=2
3(1/4)^2, 3(1/16), 3/16
true
D. 12
das is obviously false but anyway
3(1/4)^12=3(1/big number)=3/big number=small number but not zero
answer is A,B,C
circumference = 2 x PI x radius
42 = 2 x 3.14 x radius
42 = 6.28 x radius
radius = 42 / 6.28 = 6.687
= 6.69 inches
3 feet is equal to 1 inch if she measured 3 inches to equal 9 feet
44/35 in simplest form is 1 9/35.
Hope this helps!
Answer:
Step-by-step explanation:
C=5x+2y
Feasible points are (2,-2),(2,2),(-3,1) and (-1,-2)
at (2,-2) , C=5(2)+2(-2)=10-4=6
at (2,2) ,C=5(2)+2(2)=10+4=14
at (-3,1) ,C=5(-3)+2(1)=-15+2=-13
at (-1,-2) ,C=5(-1)+2(-2)=-5-4=-9
Maximum value is 14 at (2,2) .
Minimum value is -13 at (-3,1)
