Answer:
True (-∞, ∞)
Step-by-step explanation:
−11 + 16 ≤ −5 + 16
5 ≤ 11
X the 1st table
y the second
z the third
The equation is : x+y+z =16.9
But we know (given) that x=2y & z=(1/3)y
Calculate everything in term of x:
x= 2y==> x/2 =y
z=(1/3)y ==> & since y=x/2 then z= (1/3)(x/2)==> z=x/6; y=5.07 & z =1.69
x + x/2 + x/6 = 16.9===>1.666x = 16.9===> x= 10.14
420 x 0.85 = 357
357 out of the 420 said they drink coffee.
Answer:
1 cause when I solve with the college method it is equal to 1
trust me boi
Step-by-step explanation:
To get the answer we have to substitute x=3 and add 6 to the result.
Lets do this
f(x)=7-2x
f(3)=7-2*3=7-6=1
f(3)+6=1+6=7 - its the result
