Answer:

The range is the output value or the y value.

You would work backwards to find the domain.

f(x) = 4x - 1                              f(x) = 4x - 1

3 = 4x - 1                                    7 = 4x - 1

add 1 to both sides                    add 1 to both sides

4 = 4x                                            8 = 4x

divide both sides by 4              divide both sides by 4

x = 1                                              x = 2

f(x) = 4x - 1                                  f(x) = 4x - 1

11 = 4x - 1                                      15 = 4x - 1

add 1 to both sides                      add 1 to both sides

12 = 4x                                              16 = 4x

divide both sides by 4                  divide both sides by 4

x = 3                                                    x = 4

Domain { 1, 2, 3, 4}

Write this number in expanded form 382,706
77julia77 [94]

Answer:

Expanded form : 300,000 +80,000 +2000 +700 +6.

Step-by-step explanation:

Given  : 382,706.

To find : Write this number in expanded form.

Solution : We have given  382,706.

We can  see 3 is at hundred thousand place = 300,000

8 is at ten thousand place = 80,000.

2 is at thousand place  = 2000.

7 is at hundred place  = 700.

6 is at ones place = 6

Then

Expanded form : 300,000 +80,000 +2000 +700 +6.

Therefore, Expanded form : 300,000 +80,000 +2000 +700 +6.

While exercising, a person’s recommended target heart rate is a function of age. The recommended number of beats per minute, y ,
Deffense [45]

Answer:

170 heart beat per minute.

Step-by-step explanation:

While exercising, a person’s recommended target heart rate is a function of age. The recommended number of beats per minute, y, is given by the function y = f(x) = − 0.85x + 187 where x represents a person’s age in years.

So, if my age is 21 years i.e. x = 21, then the number of recommended heart beats per minute for my age will be

y = f(21) = - 0.85(21) + 187 = - 17.85 + 187 = 169.15 ≈ 170. (Answer)

{Taking the larger integer value}

Identify the arc length of TV in terms of π. (image is attached)
uranmaximum [27]
Use the formula of arc length that is
s = rθ
where s = arc length, r = radius, θ = angle (unit must be in radian)
Given r = 5 in and θ = 48°( π /180°) = (4/15)* π = 0.2667 π,
s = 5 in (0.2667π) = 1.333 π in

i have 60+8x=108 x=6 but for the other equation i dont know how to get rid of the 3x to solve for the y.
LUCKY_DIMON [66]
Angle a is congurent to angle e, so 60+8x=108
same with c and g.
so 8y-3x=62
just plug in x for there (6)
so 8y-24=62
then 8y=88
y=11
