Answer:
-16
Step-by-step explanation:
2xy + 3yz - xyz
x = 2, y = -2, z = 4
First, plug these values into the equation.
2(2)(-2) + 3(-2)(4) - (2)(-2)(4) = ?
Next, multiply the parentheses.
(-8) + (-24) - (-16) = ?
When you add a negative, you are actually subtracting the number. And when you subtract a negative, you are actually adding the number. Apply this to the equation.
-8 - 24 + 16 = ?
Now, simplify from left to right.
-32 + 16
-16
Your answer is -16.
Hope this helps!
Answer:
reduce, since 4/5 is smaller than 1
Step-by-step explanation:
We see that this function has a horizontal asymptote that crosses the y-axis at 2. This means that we can eliminate choices A and C.
From there, we can plug in values for points on the graph into the equation to see if they are true.
f(x)=6(1/3)^x+2
f(1)=6(1/3)^1+2
f(1)=2+2
=4 (Gives us the other coordinate)
f(x)=4(1/3)^x+2
f(1)=4(1/3)^1+2
=(4/3)+2
=3.33 (Does not give us the other coordinate)
Our correct answer choice is B

The horizontal sums of the survey numbers are 200, so the numbers in the left chart are the survey values divided by 200.
The vertical sum in the first column is 188, so the first column of the right chart will be 76/188 and 112/188. Likewise, the vertical sum in the second column is 212, so the numbers will be 124/212 and 88/212.
Once you find the first number in each case, the second number is that value subtracted from 1, since the total of the two must be 1.
Answer:
2.1
Step-by-step explanation:
y/sinY = z/sins
y/sin(15) = 8/sin(94)
y = sin(15) × 8/sin(94)
y = 2.075608439
