Answer:
The first choice is correct
Step-by-step explanation:
$32.00 x 15% = 4.80. 32.00-4.80=27.20. Another way to work it is the first choice, subtracting 15% from 100% and then multiplying 85% by $32.00. Same answer
Answer:
x ≥ −42
Step-by-step explanation:
Let's solve your inequality step-by-step.
x/7≥−6
Step 1: Simplify both sides of the inequality.

Step 2: Multiply both sides by 7.
x ≥ −42
Answer:
y = 1.25
Step-by-step explanation:
Use the direct variation equation y = kx, and solve for k:
y = kx
-10 = k(40)
-0.25 = k
So, the equation is y = -0.25x. Solve for y when x = -5
y = -0.25x
y = -0.25(-5)
y = 1.25
So, y = 1.25 when x = -5
Answer:
48
Step-by-step explanation:
Answer:
Thus, the graph of the function
is given below.
Step-by-step explanation:
We are given the ph of a particular solution as
, where x represents the concentration of hydrogen ions in the solution.
Since, the function is given by, 
So, we see that,
The domain of the function is {x | x≥2 } as logarithm function is not defined at zero.
Moreover, we see that,
As
, the function 
Thus, the graph of the function
is given below.
