The true statements about the function y = 3x are I, II, IV ⇒ 4th

Step-by-step explanation:

The direct variation is:

  • A mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other
  • The constant is called the constant of variation
  • The direct variation is represented graphically by a line passes through the origin
  • If y varies directly with x, then the equation of variation is y = kx, where k is the constant of variation

∵ y = 3x

- One variable is equal to the product of a constant and the

   other variable

∵ The equation is in the form of the direct variation

∴ The function is a direct variation ⇒ I

∵ The direct variation represented by a line passes through the origin

∴ y = 3x is represented graphically by a line passes through the origin

∴ The function goes through the origin ⇒ II

∵ y = 3x is a direct variation

∴ 3 represents the constant of variation

∴ The constant of variation is not 1/3 ⇒ III

∵ y = 3x

∵ x = 2

- Substitute x by 2 to find y

∴ y = 3(2)

∴ y = 6

∴ y is 6 when x is 2 ⇒ IV

The true statements about the function y = 3x are I, II, IV

Aleks [24]
If she was really committed and wanted to bake 11 pies every day for a year, she would be able to make 11•365 pies. Unless it's leap year. Then she would be able to make 11•356 pies.

Maths * Henry is mixing concrete. To make concrete he needs to mix cement, sand and gravel in the ratio 4 : 3 : 1 by weight. Hen
Mice21 [21]

Answer:

His 55 kg of cement is 5 kg short of the 60 kg he needs.

Step-by-step explanation:

Let r be a ratio useful in determining how much of each ingredient Henry needs:

4/8 of the mix is cement, 3/8 is sand and 1/8 is gravel.

4/8 of the total 120 kg must then be 60 kg made up of cement;

3/8                                 must then be 45 kg made up of sand; and

1/8                                   must then be 15 kg made up of gravel

His 55 kg of cement is 5 kg short of the 60 kg he needs.
