Monica [59]3 years ago

Answer:

x= -2

y=0

z= 1

Step-by-step explanation:

{-x+5y-10z=-8

2x-y+10z=6}

{2x-y+10z=6

-7x-3y-10y=4}

{-x+5y-10z=-8

2x-y+10z=6} = x+4y=-2

{2x-y+10z=6

-7x-3y-10y=4} = -5x-4y=10

{x+4y=-2

-5x-4y=-10}. =. y= 0 x= -2

substitute x and y in -x+5y-10z=-8

-(-2)+5(0)-10z=-8

solve for z

z= 1

(x,y,z) = (-2,0,1)

hope this helps

The ratio of ages of kissi and esinam is 3:5 and esinam is 3:5 The sum of ages of all 3 is 147 years.whats the age difference be
Sergio039 [100]

Answer:

48 years.

Step-by-step explanation:

Consider the complete question is "The ratio of ages of kissi and esinam is 3:5 and that of esinam and lariba is 3:5. The sum of ages of all 3 is 147 years. whats the age difference between oldest and youngest ?"

It is given that

Kissi : Esinam = 3:5 = 9:15

Esinam : Lariba = 3:5 = 15:25

So, the combined ratio is Kissi : Esinam : Lariba = 9:15:25

Let ages of Kissi, Esinam, Lariba are 9x, 15x and 25x.

Sum of ages of all 3 is 147 years.

9x+15x+25x=147

49x=147

x=3

The value of x is 3. So, the age of all three are

Kissi=9x=9(3)=27

Esinam=15x=15(3)=45

Lariba=25x=25(3)=75

Since Lariba is oldest and Kissi is youngest, therefore, the difference between their ages is

75-27=48

Hence, difference between oldest and youngest is 48 years.

5x-7=2x+8 solve for x
Rzqust [24]

Answer:

x=5

Step-by-step explanation:

Simplifying 5x + -7 = 2x + 8 Reorder the terms: -7 + 5x = 2x + 8 Reorder the terms: -7 + 5x = 8 + 2x Solving -7 + 5x = 8 + 2x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -7 + 5x + -2x = 8 + 2x + -2x Combine like terms: 5x + -2x = 3x -7 + 3x = 8 + 2x + -2x Combine like terms: 2x + -2x = 0 -7 + 3x = 8 + 0 -7 + 3x = 8 Add '7' to each side of the equation. -7 + 7 + 3x = 8 + 7 Combine like terms: -7 + 7 = 0 0 + 3x = 8 + 7 3x = 8 + 7 Combine like terms: 8 + 7 = 15 3x = 15 Divide each side by '3'. x = 5 Simplifying x = 5

What is the domain and range of g(x)= -|x+2| -1
solmaris [256]

g(x)= -|x+2| -1


The domain is the input values, or x values

it is all real number


The range is the output values, or g(x)

the absolute value at is smallest is 0

0-1 is -1  this is the max since the absolute value is multiplied by -1

g(x) <=-1

the output is less than or equal to -1
