Answer:

Step-by-step explanation:

1) Write 8x+14 as 2(4x+7) and now multiply by 1/2 so that we get 4x+7

2)Subtract 7 from both sides

4x+7=39

-7 -7

4x=32

3) Divide by 8

x=8

Thus we get x=8 as answer

So reasons are

i) Distributive property

ii) Subtraction property of equality

iii) Division property of equality

Answer: x = 8

Step-by-step explanation:

1/2(8x+14) = 39 (given)

4x + 7 = 39 (open the bracket)

4x = 39 -7 (collect like term)

4x = 32 (divide bothside by 4)

4x/4 = 32/4

x=8

How do i find the decumal equivalent for 2 over 3

Dovator [93]

To find the decimal equivalent for 2/3, you simply divide 2 by 3.
$2 \div 3$
After dividing, the decimal equivalent will be about 0.6666666667

If the measure of angle 2 is (5 x + 14) degrees and angle 3 is (7 x minus 14) degrees, what is the measure of angle 1 in degrees

ArbitrLikvidat [17]

Answer:

89 degrees

Step-by-step explanation:

The angle 1 is the same as angle 3.

Angle 2 is the same as angle 4.

The sum of these four angles is 360 degrees.

We have that:

Angle 2 = Angle 4 = 7x - 14

Angle 3 = Angle 1 = 5x + 14

Finding x:

Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360

2*(5x + 14) + 2*(7x - 14) = 360

10x + 28 + 14x - 28 = 360

24x = 360

x = 15

Angle 1:

5x + 14 = 5*15 + 14 = 89 degrees

Please help !!!!!!!!!!!

atroni [7]

Answer:

-3

Step-by-step explanation:

B is correct but based on the fact that you selected it I'll assume you know why (comment if you want me to explain it)

Then for two lines to be paralell it means that their lines never intersect

The only way for this to be possible is if the lines have the same slope.

This means that the answer is -3

Find the period of the function. y=3 sin x/8

Alexus [3.1K]

Answer:

The period of given function is $Period = 16\pi$

So, Option B is correct.

Step-by-step explanation:

In this question we need to find the period of the function y= 3 sin x/8

The formula used to find period of function is: $\frac{2\pi }{b}$

We need to know the value of b.

To find the value of b we compare the standard equation with the equation of function given.

Standard Equation: y = a sin(bx - c) +d

Given Equation: y= 3 sin(x/8)

Comparing we get:

a= 3

b= 1/8

c= 0

d=0

So, we get the value of b i.e 1/8. Putting it in the formula to find period of given function.

$Period = \frac{2\pi }{b}$

$Period = \frac{2\pi }{\frac{1}{8}}$

Solving,

$Period = 2\pi *8$

$Period = 16\pi$

So, the period of given function is $Period = 16\pi$
