Answers

Answer:

10.6^ -14

Step-by-step explanation:

The solution of the expression (9.6x10⁻⁸) + (2x10⁻¹⁵) is 9.6 x 10⁻⁸.

What is an expression?

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

The given expression will be solved as:-

E =  (9.6x10⁻⁸) + (2x10⁻¹⁵)

First, multiply the numbers and convert them into decimal form now add both the numbers and again write in the scientific form.

E =  9.6 x 10⁻⁸.

Therefore, the solution of the expression (9.6x10⁻⁸) + (2x10⁻¹⁵) is 9.6 x 10⁻⁸.

twice the difference of a number and 5 is 7​

Answers

Answer:

8.5

Step-by-step explanation:

The required value of the number is 8.5 which is twice the difference between a number and 5 is 7​.

How to solve this problem?

To solve this problem, we first need to express the given information in terms of a mathematical equation.

The statement "Twice the difference of a number and 5 is 7" can be represented as the equation 2 × (x - 5) = 7, where x is the number we're trying to find.

Next, we can solve this equation to find the value of x. To do this, we can first distribute the 2 on the left-hand side of the equation to get 2x - 10 = 7.

Then, we can add 10 to both sides of the equation to get 2x = 17.

Finally, we can divide both sides of the equation by 2 to get x = 17/2 = 8.5.

Therefore, the required value of the number is 8.5.

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Step-by-step explanation:

7z²+8z+3-3z²=0

4z²+8z+3=0

(2z+3)(2z+1)=0

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Answer:

Step-by-step explanation:

7z^2 + 8z + 3 = 3z^2

4z^2 + 8z + 3 = 0

(2z + 3)(2z + 1) = 0

2z + 3 = 0

z = -3/2

2z + 1 = 0

water cost $2 for 8 bottles orange juice cost a $1.50 for 3 bottles which is more expensive per bottle ​

Answers

I believe you can use ratios and multiply both of them like fractions to get the same amount of bottles and compare the prices fairly.


2:8 = 2/8
1.5:3 = 1.5/3


(2/8)3 = 6/24 or $6 per 24 bottles
(1.5/3)8 = 12/24 or $12 per 24 bottles


In conclusion, the latter ($1.50 for 3) costs more than the $2 per 8.


Answer:

orange juice

Step-by-step explanation:

1 water -> 2÷8

                = 0.25

1 orange juice ->1.50 ÷ 3

                    = 0.50

hence, orange juice is more expensive

How does the graph of a linear function compare with an absolute value function?

Answers

Answer:

In contrast, linear equations can describe values that are negative, zero or positive. As a result, the range of an absolute value function is zero and all positive numbers, while the range of a linear equation is all numbers.

The function inside the absolute value is NOT linear, therefore the graph contains curves.
