3x + 2y - 4z/x for x=5, y=-2, z=10
3x + 2y - 4z/x
3(5) + 2(-2) - 4(10)/(5)
15 - 4 - 40/5
15 - 4 - 8
11 - 8

The first step for solving this expression is to write the division as a fraction.
x +

× x
Calculate the product.

Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:

Now multiply the terms with the same base by adding their exponents.

Finally,, add the numbers together to get your final answer.
x +

Answer:
Y values will stay the same
Step-by-step explanation:
Reflecting over the Y axis will alter the distance left and right but not up and down. so only Y remains unchanged
Answer:
The rate of change with respect to monthly sales is 4000 - 200t.
Step-by-step explanation:
The sales per month (monthly sales) of the new sound system being sold by Sunny Electronics is given by q(t) = 4000t - 100
units per month, where t is number of months from the introduction of the sound system.
The price of each unit of the sound system charged by Sunny Electronics is given by p(t) = 2000 -
.
The rate of change with respect to monthly sales will be given by the equation
.
3x + 5x + 7x = 180
15x = 180
x = 180/15
x = 12
Largest angle = 7x = 7*12 = 84°
