Answer:
- 62Step-by-step explanation:
Evaluate x3−y2 if x=2 and y=34
substitute x=2 and y=32 into the expression:
= x3 - y2
= (2)3 - (34)2
= 6 - 68
= -62
An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression x³−y², when x=2, y=34 is −1,148.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given the expression x³−y² and the value of the expression when x=2 and y=34 can be calculated by substituting the values in the expression. Therefore, the expression can be written as,
x³ − y²
Substitute the value of x and y in the expression,
= (2)³ − (34)²
Opening the bracket,
= 8 − 1,156
= −1,148
Hence, the value of the expression x³−y², when x=2, y=34 is −1,148.

What is the inverse operation of a power or exponent?
Answer:
The inverse of a power function of exponent n is a nth root radical function. For example, the inverse of y = 10x^2 is y = √(x/10) (at least for positive values of x and y).
5|2x - 3| + 4 = 9
How do you solve this
Answer:
x = 2, or x = -1
Step-by-step explanation:
If 2x - 3 is inside the parenthesis (), then the value of x is 2.
If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.
Solution 1
(10x-15) + 4 = 9
10x -11 = 9
10x = 20 -> x = 2
Solution 2 (Not 100% sure)
|10x -15| +4 = 9
10x + 15 +4 = 9
10x + 19 = 9
10x = -10 -> x = -1
Please correct me if I'm wrong.

What is the range & domain of the set
{(−6, 14), (10, 19), (4, -9), (3, 2), (6, −13)}
Answer:
The domain is {-6, 3, 4, 6, 10}
The range is {-13, -9, 2, 14, 19}
Step-by-step explanation:
Any set of ordered pairs has a domain and a range
The domain is the values of x-coordinates of all ordered pairs
The range is the values of y-coordinates of all ordered pairs
∵ The set is {(-6, 14), (10, 19), (4, -9), (3, 2), (6, -13)}
∵ x-coordinates of all points are -6, 10, 4, 3, 6
→ These values are the domain of the set
∴ The domain is {-6, 3, 4, 6, 10}
∵ y-coordinates of all points are 14, 19, -9, 2, -13
→ These values are the range of the set
∴ The range is {-13, -9, 2, 14, 19}

In 1819, the United States purchased Florida from Spain for
$5 X 106. The area of Florida is about 6.6 x 104 square miles.
Which key strokes on a calculator will give the cost the
United States paid for each square mile of Florida?
A) 6.6EE4×5EE(-)6
B) 6.6EE4÷5EE6
C)5EE6×6.6EE4
D)5EE6÷6.6EE4
Answer:
D. 5 x 10⁶ ÷ 6.6 x 10⁴Step-by-step explanation:
If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;
6.6 x 10^4 mi² = $5 X 10^6
1mi² = $x
Cross multiply;
$5 X 10^6 * 1 = 6.6 x 10^4 * x
6.6 x 10⁴ x = 5 X 10⁶
Divide both sides by 6.6 x 10⁴ to get x;
6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴
x = 5 x 10⁶ ÷ 6.6 x 10⁴
x = 0.76*10⁶⁻⁴
x = $0.76*10²
Hence the key strokes on a calculator will give the cost the United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴

Let r varies inversely as u, and r = 8 when u =5. Find r if u=55
Answer:
Step-by-step explanation:
Given that, r varies inversely with u. r=k÷u, k being the constant.
Therefore, k=8×5, ( after making k the subject of your formula).
This implies that k=40.
Now, according to the formula r=k÷u,
r=40÷55
Therefore, r=0.72

−7 + 3(8n − 8) = 8(7 + 3n) please show work
Answer:
Step 1: Simplify both sides of the equation.
−7+3(8n−8)=8(7+3n)
−7+(3)(8n)+(3)(−8)=(8)(7)+(8)(3n)(Distribute)
−7+24n+−24=56+24n
(24n)+(−7+−24)=24n+56(Combine Like Terms)
24n+−31=24n+56
24n−31=24n+56
Step 2: Subtract 24n from both sides.
24n−31−24n=24n+56−24n
−31=56
Step 3: Add 31 to both sides.
−31+31=56+31
0=87

Which describes the role of oxygen in photosynthesis? A. It is a reactant, so it is released by the plant. B. It is a product, so it is released by the plant. C. It is a reactant so it enters the plant. D. It is a product, so it enters the plant.
Answer:
B) It is a product, so it is released by the plant.
Step-by-step explanation:
- Plants release oxygen for humans and humans give carbon dioxide to plants.
- The role of oxygen in photosynthesis is a waste product.
Answer: The oxygen gas is a product, so it is released by the plant.
Explanation:
Photosynthesis is defined as the process by which the producers make glucose with the help of carbon dioxide and water in the presence of sunlight.
The chemical equation representing this reaction follows:
In the above reaction, oxygen gas is written on the product side. So, it is formed by the plant and is released.
Hence, the oxygen gas is a product, so it is released by the plan.
The value of a collectible coin can be represented by the equation y = 2 x + 15, where x represents its age in years and y represents its total value in dollars. What is the value of the coin after 19 years?
Answer:
y = 53
Step-by-step explanation:
To get the answer, first put 19 in place of the x, and then times that iwth two, getting 38, you add that to 15. The answer is 53.
Answer:The Value of the coin after 19 years is $53.
Step-by-step explanation:If x=age, then simply substitute the x in “2x+15” for 19.After you do that you should get y=2(19)+15.Do the math to get y=38+15. Y=53.
