Answer:

You move all terms to the left;

6-(1/2z)=0

Domain of the equation: 2z)!=0

z!=0/1

z!=0

You add all the numbers together, and all the variables;

-(+1/2z)+6=0

You get rid of parentheses;

-1/2z+6=0

You multiply all the terms by the denominator;

6*2z-1=0

You multiply elements;

12z-1=0

You move all terms containing z to the left, all other terms to the right;

12z=1

z=1/12

And your answer is: z=1/12

What is the slope of the line? A. 2 B. -2 C. 1/2 D. -1/2

iogann1982 [59]

slope m = - 2 → B

calculate m using the ' gradient formula '

m = (y₂ - y₁)/(x₂ - x₁)

choosing 2 'clear ' coordinates from the graph of the line

(x₁, y₁) = (0, 7) and (x₂, y₂) = (7, - 5 $\frac{(- 5 - 7)}{(6 - 0)}$ ) = $\frac{- 12}{6}$ = - 2

m =

Please help me out with this

Genrish500 [490]

Answer:

x = 17

Step-by-step explanation:

For the parallelogram to be a rhombus then then the diagonal must bisect the given angle, thus

3x - 11 = x + 23 ( subtract x from both sides )

2x - 11 = 23 ( add 1 to both sides )

2x = 34 ( divide both sides by 2 )

x = 17

Find the exact value of the area of a circle whose radius is 3.1

GuDViN [60]

Step-by-step explanation:

$area \: of \: circle = \pi \: {r}^{2} \\ = 3.14 \times {(3.1)}^{2} \\ = 3.14 \times 9.61 \\ = 30.1754 \: {unit}^{2} \\$

Where does the line through (1, 0, 1) and (4, −3, 3) intersect the plane x + y + z = 6?

Irina-Kira [14]

Parametrically for real t the line is

$(x,y,z) = (1-t)(1,0,1) + t(4,-3,3)$

$(x,y,z) = (1,0,1) + t(4-1,-3-0,3-1)$

$(x,y,z) = (1,0,1) + t(3,-3,2)$

That's three equations; we substitute into

$x+y+z=6$

$(1+3t)+(0-3t) + ( 1+2t)=6$

$2t=4$

$t=2$

$(x,y,z) = (1,0,1) + 2(3,-3,2) = (7,-6,5)$

The intersection is a single point (7,-6,5).

Li is making beaded necklaces. For each necklace, she uses 22 spacers, plus 9 beads per inch of necklace length. Write an equati

NeTakaya

Answer: y = 9x

Step-by-step explanation:

Li needs to use 9 beads for each inch of necklace.

X = Length of Necklace

Y = Number of beads needed

y = 9x

For instance, assuming a necklace is 8 inches long, how many beads will be needed;

= 9x

= 9 * 8

= 72 beads
