We are given the expression x³ - 2y² - 3x³ + z⁴. We have to evaluate it at a given set of x, y, and z values. Before then, let's combine like terms.

x³ - 2y² - 3x³ + z⁴

= -2x³ - 2y² + z⁴ <-- by combining like terms

Now we evaluate for x=3 y=5 z = -3

= -2(3³) - 2(5²) + (-3⁴) <-- by putting in for x, y, z

= -2(27) - 2(25) + 81 <--- parentheses and exponents first in order of operations

= -54 - 50 + 81 <---- multiplication is next

= -4 + 81

= 77


Thus, we evaluate and it's 77.

Answer:

The value of x is 5

Step-by-step explanation:

In the given triangle

∵ A segment joining two points lie on the two side

∵ This segment is parallel to the third side

∴ This segment divides the two sides into parts that have the same ratio

→ That means x over 2x - 3 equal to 10 over 14

∵ \frac{x}{2x-3} = \frac{10}{14}

→ By using cross multiplication

∴ 10 × (2x - 3) = x × 14

∴ 10(2x) - 10(3) = 14x

∴ 20x - 30 = 14x

→ Add 30 to both sides

∵ 20x - 30 + 30 = 14x + 30

∴ 20x = 14x + 30

→ Subtract 14x from both sides

∵ 20x - 14x = 14x - 14x + 30

∴ 6x = 30

→ Divide both sides by 6

∴ x = 5

∴ The value of x is 5

To buy a truck you can pay $13,000 cash or put down $4250 and make 24 monthly payments of $595.54. How much would you save by pa
-Dominant- [34]

Savings by paying cash is $1,289.6.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

To buy a truck cash payment = $13,000

And, Put down cash = $4250

Now, Calculate the total amount with payments;

Total amount with payment = Payment amount * Total month

                                          = $595.54 * 24

                                          = $14,289.6

And, Calculate the total amount saved by paying cash;

Savings by paying cash = Total amount with payments - Cash payment

                                    =  $14,289.6 - $13,000

                                    = $1,289.6

Hence, Savings by paying cash is $1,289.6.

How do you compare proportional relationships
Likurg_2 [28]

Answer: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
