Answer:

x=-1/2

Step-by-step explanation:

Solving

2x-1+8=6

2x+7=6

2x=6-7

2x=-1

x=-1/2

Checking

put x=-1/2 in equation

LHS 2(-1/2)-1+8

=-1-1+8

=8-2

=6

RHS =6

Answer: x=-1/2

<u>Simplify both sides of the equation</u>

<u></u>2x+-1+8=6<u></u>

<u></u>(2x)+(-1+8)=6 (Combine Like Terms)

2x+7=6

<u>Subtract 7 from both sides</u>

<u></u>2x+7-7=6-7\\2x=-1<u></u>

<u></u>

<u>Divide both sides by 2</u>

2x/2=-1/2\\x=-1/2

Find the missing side or angle.
bonufazy [111]

Answer:

c = 6.1

Step-by-step explanation:

Given that: B = 18° , C = 152°,  and b = 4.

The missing side, c, can be determined by applying the sine rule which states that:

\frac{b}{Sin B} = \frac{c}{Sin C}

\frac{4}{Sin 18^{o} } = \frac{c}{Sin 152^{o} }

c = \frac{4* Sin 152^{o} }{Sin 18^{o} }

 = \frac{1.8779}{0.3090}

 = 6.0773

c = 6.1

Therefore,  the value of the missing side, c, is 6.1

What is the perimeter of the figure to the nearest tenth of a millimeter?
Pavlova-9 [17]
We have to calculate the perimeter of the figure to the nearest tenth of a millimeter. This figure is made of a rectangle and a half of a circle. The first figure has the perimeter: 3 + 6 + 3 = 12 mm. The second figure has the perimeter: 2 * Pi * r / 2 = Pi * r ; and the radius : r = 6/2 = 3 mm. So Pi * 3 = 3.14 * 3 = 9.42. Fimally : 12 + 9.42 = 21.42 or 21.4 to the nearest tenth. Answer: C. 21.4 millimeters<span>. </span>

Help ASAP!!!!<br> Which statement about the graph of the function y=(1/3)x are true?
mafiozo [28]

Answer:


Step-by-step explanation:

1) False:  The function is decreasing (because the base, 1/3, is between 0 and 1).

2) True:  The function is decreasing (see #1, above)

3) False:  There is no x-intercept.

4) True:  If x is 0, then y = (1/3)^0 = 1.

5) False:  the range consists of the set of all real numbers greater than zero.
