If f(x) =- 2x + 5, find f(4x)​

Answers

Answer 1

Answer:

[tex]f(4x)=-8x+5[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)=-2x+5[/tex]

And we want to find:

[tex]f(4x)[/tex]

So, by substitution, we acquire:

[tex]f(4x)=-2(4x)+5[/tex]

Multiply. So, our answer is:

[tex]f(4x)=-8x+5[/tex]

Given: the function f defined by f(x) = 3x2 . Which statement is true? 1) f(0) = 0 2) f(−2) = f(2) 3) f(5) + f(2) = f(7) 4) f(5) − f(2) = f(10)

Answers

Answer:

f(0) = 0 and f(−2) = f(2)

Step-by-step explanation:

Given: the function f defined by f(x) = 3x²

f(0) = 3(0)²

f(0) = 0

f(-2) = 3(-2)²

f(-2) = 3(4)

f(-2) = 12

f(2) = 3(2)²

f(2) = 3(4)

f(2) = 12

Hence f(-2) = f(2)

Therefore the correct options are  f(0) = 0 and f(−2) = f(2)

For which equation is g = 0 not the solution?

12 g = 0
3 g = 30
g + 8 = 8
9 g = 0

Answers

Answer:

3g = 30

Step-by-step explanation:

Well, lets check each one to see if any leaves g = 0

12g = 0      (Given)

÷12   ÷12    (Get "g" on its own)

g = 0          (0 ÷ 12 = 0)

We know it is not this one since g = 0

3g = 30    (Given)

÷3     ÷3    (Get "g" on its own)

g = 10       (30 ÷ 3 = 10)

This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.

Just in case, I will do the other options just not as in-depth!

g + 8 = 8

   -8    -8

g = 0

9g = 0

g = 0

By multiplying 60 by .50, you would get 30, that’s the amount of discount. Then subtract 30 from 60. Your answer would be $30

Answer:

It would be 30$.

Step-by-step explanation:

Lets break this down.

50% off 100 would be 50. 50 is half of 100, therefore we know that 50% is half off of something.

We can either divide 60 by 2, or split 60 in half. In turn, we receive 30.

In circle O below AB is a diameter and m

Answers

The measure of arc AC is 40°
Step-by-step explanation:
In any circle the measure of an inscribed angle is one-half the measure of its subtended arc
In circle O
∵ ∠BAC is an inscribed angle subtended by arc BC
∴ m∠BAC = m arc BC
∵ m∠BAC = 70°
- Substitute it in the the expression above
∴ 70 = m arc BC
- Multiply both sides by 2
∴ 140 = m arc BC
∴ The measure of arc BC is 140°
∵ AB is a diameter
- The diameter divides the circle into two equal arcs
∴ m of arc ACB = measure of the circle
- The measure of the circle is 360°
∴ m of arc ACB = (360°)
∴ m of arc ACB = 180°
∵ m arc BC + m arc AC = m arc ACB
∴ 140° + m arc AC = 180°
- Subtract 140 from both sides
∴ m arc AC = 40°
The measure of arc AC is 40°

Rebecca is sharing a pizza with some friends. Below is an Image of how she cuts the pizza.
AE is a diameter of the 20 in pizza!
a) If rebecca wants the biggest piece which one would she choose ( name it by its arc)? Be careful the image may not be drawn to scale
b) Rebecca loves stuffed crust!! She decides to figure out the length of cheese in her piece of the crust ( hint find the arc length

Answers

Answer:

a) The piece of pizza she should choose is BE

b) The length of the cheese in her piece of the crust is approximately 20.07 inches

Step-by-step explanation:

The given diameter of the pizza, AE = 20 in.

The measure of the arc AB, [tex]m\widehat{AB}[/tex] = ∠ACB = 65°

The measure of the arc DE, [tex]m\widehat{DE}[/tex] = ∠DCE = 110°

Given that AE is the diameter of the circular pizza, we have;

[tex]m\widehat{BE}[/tex] = ∠BCE = 180° - ∠ACB = 180° - 65° = 115°

Similarly;

∠ACD = 180° - ∠DCE = 180° - 110° = 70°

a) The biggest piece of pizza is the piece with the largest angle which is the  piece formed by arc BE, [tex]m\widehat{BE}[/tex] = 115°

The piece of pizza she should choose is the piece, BE

b) Arc length = (Arc angle)/360 × (Circumference of the circle)

The circumference of the circular pizza, C = π × Diameter = π × length [tex]\overline {AE}[/tex]

∴ C = π × 20 in.

The arc length of the arc BE = 115/360 × π × 20 = 115·π/18 ≈ 20.07

The length of the cheese in her piece of the crust, l = The arc length of the arc BE ≈ 20.07 inches.

What are the coordinates of the point obtained if the point A=(3,7) is rotated 180 degrees about the origin?
A. (-3,7)
B. (-3,-7)
C. (-7,-3)
D. (-7,3) ​

Answers

Answer:

B. (-3, -7)

Step-by-step explanation:

Anytime you rotate a number 180° about the origin, the numbers in the coordinates become their opposites.

-3 is the opposite of 3 and -7 is the opposite of 7.

Therefore, your new coordinates are (-3, -7)

(x,y) becomes (-x,-y)
