cupoosta [38]3 years ago
7 0

Answer:

-1 ≤ x  < 3

Step-by-step explanation:

2 ≤ 2x + 4 < 10

Subtract 4 from all sides

2-4 ≤ 2x + 4-4 < 10-4

-2 ≤ 2x  < 6

Divide all sides by 2

-2/2 ≤ 2x/2  < 6/2

-1 ≤ x  < 3

Write a rule for g described by the transformation of the graph of f...
Svetlanka [38]

Answer:

g(x) = 4-4\sqrt{x}

Step-by-step explanation:

Given

f(x) = 4\sqrt{x}+1

1. 5 units down translation

2. Reflection in the x-axis

Required

Determine the resulting function g

1. 5 units down translation

This is defined by the rule:

A down translation is:

f'(x) = f(x) - b

Where b is the number of units.

So, we have:

f'(x) = 4\sqrt{x} + 1 - 5

f'(x) = 4\sqrt{x} -4

2. Reflection in the x-axis

For a function f(x),

When reflected over the x-axis, it becomes -f(x)

So:

g(x) = -f(x)

g(x) = -(4\sqrt{x} - 4)

g(x) = -4\sqrt{x} +4

g(x) = 4-4\sqrt{x}

What value of n makes the equation 4(0.5n − 3) = n − 0.25(12 − 8n) true?
svlad2 [7]

Answer:

n = -9

Step-by-step explanation:

4(0.5n − 3) = n − <u>0.25(12 − 8n)</u>

2n - 12 = n - <u>3 + 2n</u>

2n - 12 = 3n - 3

2n - 3n =  - 3 +12

-1n  = 9

n = -9
