Step-by-step explanation:

4) there are no solutions

expand the equation

-2v+4=-3-2v

the -2v cancell out and you are left with 4=-3 which is impossible

6) the answer is 5

expand

8x+38=18+12x

20=4x

x=5

8) the answer is 5

expand

-3v-12=2v-37

25=5v

v=5

Hope that helps :)

14. Trick question, ignore the side.

Call the angle b.

34 + b + b = 180

2b = 146

b = 73

choice b

15. That's intersecting chords so the product of the segment lengths are equal:

5(22)=10 x

x = 5(22)/10 = 11

choice a

16. Intersecting tangent and secant;

$x^2 = 5(19)$

$x = \sqrt{95} \approx 9.75$

Choice a

MATCH THE number WITH ITS OPPOSITE

ycow [4]

To match the number with the opposite, we are flipping the sign. If the sign is originally a negative, it would become a positive, and vice versa.

Term: 3.2 Match (Opposite): B) - 3.2

Term: -2.3 Match (Opposite): D) 2.3

Term: -1.5 Match (Opposite): C) 1.5

Term: 5.1 Match (Opposite): A) -5.1

Solve x2 - 8x = 3 by completing the square. Which is the solution set

Simora [160]

Answer:

4\pm\sqrt{19}

Step-by-step explanation:

Move everything to left side

$x^{2} -8x -3 =0$

Now to solve this square equation we need to find Descriminant

$D=b^{2} -4ac=64+12=76$

As Descriminant D is greater than 0 then we have 2 solutions which we can calculate by this formula

$x_{1,2}=\frac{-b\pm\sqrt{D}}{2a} =\frac{8\pm2\sqrt{19}}{2}=4\pm\sqrt{19}$
