Four times the sum of 8 and some number is 4. What is the number?
Lunna [17]

Answer:

\Huge \boxed{\mathrm{-7}}

\rule[225]{225}{2}

Step-by-step explanation:

Let the number be x.

4(x+8)=4

Dividing both sides by 4,

x+8=1

Subtracting 8 from both sides,

x=-7

The number is -7.

Drag each interval to a box to show if the function shown is increasing, decreasing, or neither over that interval. 6 4 10 8 1 t
Kitty [74]

Answer:

Function (4 < x < 6) and (8 < x < 10) is decreasing

Function (1 < x < 4) and (6 < x < 8) is increasing

Function (10 < x < 14) is neither increasing nor decreasing

Step-by-step explanation:

The question is incomplete. The complete question has been added as an attachment.

From the graph:

x-axis (horizontal), y-axis (vertical)

Note: moving from negative bigger number to negative smaller number is an increase.

Moving from negative smaller number to negative bigger number is a decrease.

6 < x < 8: on the x-axis, from number +6 to +8, you find on the y-axis the line moved from -7 to -4. That is an increase.

4 < x < 6: on the x-axis, from number +4 to +6, you find on the y-axis the line moved from -3 to -7. That is a decrease.

10 < x < 14: on the x-axis, from number +10 to +14, you find on the y-axis the line moved from -5 to -5. It remained on the same number. It is neither increasing nor decreasing.

8 < x < 10: on the x-axis, from number +8 to +10, you find on the y-axis the line moved from -4 to -5. That is a decrease

1 < x < 4: on the x-axis, from number +1 to +4, you find on the y-axis the line moved from -11 to -3. That is an increase.

Prove 2(2x+4)= 16 2(2x) by using the laws of exponents.<br> boris9
storchak [24]

The prove that the equation can be verified using the laws of exponents.

<h3>What is the proof of the equation given; 2^(2x+4)= 16 × 2^(2x)?</h3>

It follows from the task content that the equation given is; 2^(2x+4)= 16 • 2^(2x).

It follows from the laws of indices ; particularly, the product of same base numbers.

The evaluation is therefore as follows;

2^(2x+4)= 16 • 2^(2x)

2^(2x) • 2⁴ = 16 • 2^(2x)

2^(2x) • 16 = 16 • 2^(2x)

Hence, since LHS = RHS, it follows that the expression is mathematically correct.

What happens to the volume of a sphere when its diameter is doubled?
slega [8]

with a scale factor

length becomes scale factor * length

area becomes scale factor^2 * area

volume becomes scale factor ^3 * volume

if the diameter is doubled  the scale factor is 2

Volume becomes 2^3 * volume

the volume increases by a factor of 8
