kozerog [31]

Answer:

2 1/6

Step-by-step explanation:

13/6 is 6/6 + 6/6 + 1/6... each 6/6 = 1 sooo. 2 and 1/6 :)

orrr

6*2 is 12 (closest multiple of 6 to 13, so 2 is whole number w/ 1(/6) as a remainder

Find the missing value of the ordered triple that will make the solution to the equation x + 2y – 3z = 8 true.

erica [24]

The missing value of the ordered triple for questions 7,8,9 and 10 will be y=2,x=6,z=0, and z=-5 respectively.

<h3>What is the equation?</h3>

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

The given equation in the problem is;

7) (4, ,0)

Substitute the values in the equation;

⇒x+2y-3z = 8,

⇒4+2y-3(0) = 8

⇒2y=8-4

⇒2y=4,

⇒y=4/2

⇒y=2

8) (, -2, -2)

Substitute the values in the equation;

x+2(-2) -3(-2)= 8

x-4+6 =8

x= 8-6+4

x=8-6+4

x=6

9)(2, 3, )

Substitute the values in the equation;

⇒2+2(3)-3z = 8

⇒8-3z = 8

⇒-3z = 0

⇒z = 0/-3

⇒z= 0

10) (-3, -2, )

Substitute the values in the equation;

⇒-3+2(-2) -3z = 8

⇒-7 -3z = 8

⇒-3z = 15

⇒z = 15/-3

⇒z = -5

Hence, the missing value of the ordered triple for questions 7,8,9, and 10 will be y=2,x=6,z=0, and z=-5 respectively.

Cada par de puntos determina una recta con la pendiente dada. Halla el valor de la incógnita en cada caso: a. (3,2);(4,x); m=1 b

True [87]

Answer:

a=3,b=0,c=5,d=-4/21

Step-by-step explanation:

The formule we use to get the slope is:

m = $\frac{y2-y1}{x2-x1}$

a. (3,2);(4,x); m=1

$\frac{x-2}{4-3}=1$ → x= (1)(4-3)+2 → 3

b. (b,-1);(2,-2); m=-1/2

$\frac{-2-(-1)}{2-b}=\frac{-1}{2}$ → -1= ( $\frac{-1}{2}$ )(2-b) → $\frac{-1}{\frac{-1}{2} }-2$ → 0

c. (5,d);(9,2); m=-3/4

$\frac{2-d}{9-5}=\frac{3}{4}$ → d= ( $\frac{-3}{4}$ )(9-5)-2 → 5

d. (-1/3,3/4);(h,5/6); m=7/12

$\frac{\frac{5}{6}-\frac{3}{4} }{h-\frac{-1}{3} }=\frac{7}{12}$ → $\frac{5}{6}-\frac{3}{4}$ = $\frac{7}{12}$ ( ${h-\frac{-1}{3} }$ ) → $\frac{-4}{21}$

We get this equation with the original one:

y=mx+b

There are three forms of linear equations:

point-slope form y2-y1=m(x2-x1)

standard form Ax + By + C = 0 or Ax + By = C

and slope-intercept form y=mx+b
