Answer:

Domain : all real numbers.

Y-intercept : (0,-1)

The range is y >= -3.

Step-by-step explanation:

We have given the function:

y = 2Ix-1I -3

We have to draw the graph of this equation.

As see from the equation the domain is :

domain: all real numbers.

As we see from the graph the y-intercept is  -1 (the point where x = 0)

y-intercept = (0,-1)

The range is y >= -3.

The graph is attached with the question.

Answer:

The domain ⇒ x ∈ real number

The range ⇒ y ≥ -3

The y-intercept ⇒ (0 , -1)

Step-by-step explanation:

∵ y = 2Ix - 1I - 3

∴ y = 2(x - 1) - 3

∴ y = 2x - 2 - 3 = 2x - 5 ⇒ positive slope

∴ y = 2(-x + 1) - 3

∴ y = -2x + 2 - 3 = -2x - 1 ⇒ negative slope

∴ 2x - 5 = -2x - 1 ⇒ 4x = 4 ⇒ x = 1

∴ Y = 2(1) - 5 = -3

∴ The two lines intersect each other at (1 , -3)

∴ The domain is x ∈ real number

∴ The range is y ≥ -3

∴ The y-intercept = -1 ⇒ (0 , -1)

PLEASE HELP! i have by the end of the day to turn this in. PLEASE DONT GUESS
Naddika [18.5K]

Answer:

x = 101°

Step-by-step explanation:

the bottom left angle inside the triangle is supplementary to the angle which measures 148°, so the m∡ is 32°

47 + 32 + x = 180

79 + x = 180

x = 101°

PLEASE HELP, The blueprints for the johnsons living room has a scale of 2 inches= 5 feet. The family wants to use a scale of 1 i
olchik [2.2K]
Because we got five feet for two inches at preceding case that mean we had 2.5 feet for each inch by dividing 5 on 2 so that will give us the result 2.5 standing as well as that scale change from 2.5 to 3 for each inch in the new blueprint so by multiplying 3 feet by 2 inch that give us 6 feet width

The lateral surface area of cone A is equal to the lateral surface area of cylinder B.
Natasha2012 [34]

Answer:

TRUE

Step-by-step explanation:

Lateral area of cone is given by: πrl

where r is the radius and l is the slant height

Here r=r and l=2h

Hence, lateral area of cone A= π×r×2h

                                            =  2πrh

Lateral area of cylinder is given by: 2πrh

where r is the radius and h is the height

Lateral area of cylinder B=2πrh

Clearly, both the lateral areas are equal

Hence, the statement that:The lateral surface area of cone A is equal to the lateral surface area of cylinder B. is:

True
