2) Inserting zeros at the right end of a decimal does not change its value
0.3 = 0.3000
4) To estimate the difference between 0.31 and 0.108, subtract 0.3.
22) 75.285 + 2 + 3.871 + 0.5 = 81.656
42) 0.01 - 0.0001 = 0.0099
50) 9 - 4.63 = 4.37
Answer:
x = 7
Step-by-step explanation:
I reversed it for easy viewing:
(x+7)/3x = 2/3
<=> (x + 7).3 = 2.(3x)
<=> 3x + 21 = 6x
<=> 21 = 6x - 3x
<=> 3x = 21
<=> x = 7
Answer:
Opt. D.
Step-by-step explanation:
To solve this problem we need to focus our attention in the abs(x-1) function,
If x>1, then abs|x-1|= x-1, if x<1 then abs|x-1|= 1-x. And in the two intervals, the function opens upwards.
But our function has -3 multiplying abs|x-1|, This means that our function opens downward.
The vertex point can be found when x=1, since abs(x-1)=0. this gives f(1)=12
That 's easy!!! (x-h) ²+(x-k) ²=r²
(h, k) is the coordinate of centra
r is radius
and(x-h) ²+(x-k) ²=r² is written in standard form, which u can directly get the value of center and radius
so for ur question center is (7 and -4)
radius is 7
The answer would be 2431.
