An addition sentence, a multiplication sentence, and a division sentence are modeled on the number line. the figure shows a number line. the numbers on the number line range from negative 15 to 15 in increments of 5. between every two numbers, four marks are made such that five divisions are formed between every two numbers. three rays are made one after the other towards left. the first ray starts from 0 and goes 4 divisions left, the second ray starts from the point where the first ends and goes 4 divisions left, and the third ray starts from the point where the second ray ends and goes 4 divisions left. all the three rays are labeled as negative 4. what addition sentence is modeled? what multiplication sentence is modeled? what division sentence is modeled?

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

the answer is stop cheating on things stoopid

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
