Answer:

  (a)  (6a - 3a) + (-3+6)

Step-by-step explanation:

Assuming "properly grouped" means that parentheses are placed around each group of terms, the appropriate choice is the one that groups 'a' terms and constant terms:

  (6a - 3a) + (-3 + 6)

Answer/Step-by-step Explanation:

Circumference of a circular object = πd

Where,

π = 3.14,

d = diameter

Circumference of hula pop with diameter of 35 in:

Circumference = πd = 3.14*35 = 109.9 in

Diameter of circular pond with a circumference of 556 ft:

556 = 3.14*d

Divide both sides by 3.14

556/3.14 = d

177.07 = d

d ≈ 117 in

Circumference of magnifying glass with a diameter of 5.2 in:

Circumference = πd = 3.14*5.2 = 16.328 ≈ 16.4 cm

Diameter of car tire with a circumference of 71.6 in:

71.6 = 3.14*d

Divide both sides by 3.14

71.6/3.14 = d

22.80 = d

d ≈ 22.8 in

What is the equation when y=5x+4 is reflected over the x-axis, y-axis &amp; y=x?
tigry1 [53]

Answer:

A) y=-5x-4

B) y=-5x+4

C) y=\frac{x-4}{5}

Step-by-step explanation:

So we have the equation:

y=5x+4

Let's write this in function notation. Thus:

y=f(x)=5x+4

A)

To flip a function over the x-axis, multiply the function by -1. Thus:

f(x)=5x+4\\-(f(x))=-(5x+4)

Simplify:

-f(x)=-5x-4

B) To flip a function over the y-axis, change the variable x to -x. Thus:

f(x)=5x+4\\f(-x)=5(-x)+4

Simplify:

f(-x)=-5x+4

C) A reflection over the line y=x is synonymous with finding the inverse of the function.

To find the inverse, switch x and f(x) and solve for f(x):

f(x)=5x+4

Switch:

x=5f^{-1}(x)+4

Subtract 4 from both sides:

x-4=5f^{-1}(x)

Divide both sides by 5:

f^{-1}(x)=\frac{x-4}{5}

And we're done :)
