Which function represents g(x), a reflection of f(x) = 1/2(3)^x across the y-axis

1 answer:

3 0

They both have to be above the x axis, which makes B incorrect. B will be below the x axis. If you have a graphing calculator or know where there is one of the net, you can try it.

A and D are both wrong. The 1/2 does not become 2. What will happen is that 2 will make the graph wider.

There's only 1 answer left and that is
C <<<<<===== answer.
C reflects right across the y axis.

3x - 7x =4 I need you to help me solve and work it out

3-7 is -4 so it becomes -4x=4 divide both sides by 4 to get -x=-1 a lot of teachers dont like that negative x so you can also divide by -1 again to make it x=1
hope it helps

Y = - 2x + 1 2x - 2y = 4 Solve systems of equations by substitutions

astraxan [27]

Answer:

x= 1

y= -1

Step-by-step explanation:

y=-2x+1

2x-2y=4

substitute for y

2x-2(-2x+1)=4

reduce

2x+4x-2=4

6x=6

x=1

y= -2(1)+1

y= -1

Determine the solution set of (x - 4)2 = 12. {4 + 2√3, 4 - 2√3} {4 - 2√3, 4 - 2√3} {2√3 + 4, 2√3 - 4}

Alina [70]

Answer:

{4 + 2√3, 4 - 2√3} thus the solution is A. x = 4 + 2 sqrt(3) or x = 4 - 2 sqrt(3)

Step-by-step explanation:

Solve for x over the real numbers:

(x - 4)^2 = 12

Take the square root of both sides:

x - 4 = 2 sqrt(3) or x - 4 = -2 sqrt(3)

Add 4 to both sides:

x = 4 + 2 sqrt(3) or x - 4 = -2 sqrt(3)

Add 4 to both sides:

Answer: x = 4 + 2 sqrt(3) or x = 4 - 2 sqrt(3)

Answer:

(0, - 6)

Step-by-step explanation:

Midpoint Formula

M = (x₁ + x₂ / 2, y₁ + y₂ / 2)

Solving

M = (-3 + 3 / 2, -7 - 5 / 2)
M = (0, -12/2)
M = (0, - 6)
