When we take the absolute value of a number, we always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero). For instance, | 3 | = 3, and | –3 | = 3 also.

Assumin we solving for the intersection or solution

elimination, ya

eliminate y's

multiply firs equation by 2 and add to 2nd

we get
6x+2y=16
-x-2y=-10 +
5x+0y=6

5x=6
divide both sides by 5
x=6/5

sub back
-x-2y=-10
-6/5-2y=-10
times both sides by 5
-6-10y=-50
add 6 to both sides
-10y=-44
divide both sides by -10
y=44/10
y=22/5

(x,y)
$(\frac{6}{5},\frac{22}{5})$
or
(1.2,4.4)

Answer:

6 min

Step-by-step explanation:

5 kilometers = 5,000 meters

500/5,000 = 1/10 meaning it would take him 1/10 of an hour or 6 minutes to cover this distance.

How do you graph y=3x and y=-x-8

laila [671]

Answer:

The points for the given two linear equation as

$x_1 , y_1$ = - 2 , - 6

$x_2 , y_2$ = - 2 , 6

The graph so plotted as shown

Step-by-step explanation:

Given as :

The two linear equation are

y = 3 x ........A and

y = - x - 8 .........B

Solving equation A and B

Now, Put The value of y from eq A into eq B

So, 3 x = - x - 8

Or, 3 x + x = - 8

Or, 4 x = - 8

∴ x = $\dfrac{-8}{4}$

I.e x = - 2

Now , Put the value of x into eq A

∵ y = 3 x

∴ y = 3 × (-2)

I.e y = - 6

Again, Put the value of x into eq B

∵ y = - x - 8

∴ y = - 2 - (-8)

I.e y = 6

So, for x = - 2 , y = - 6

And for x = - 2 , y = 6

Hence , The points for the given two linear equation as

$x_1 , y_1$ = - 2 , - 6

$x_2 , y_2$ = - 2 , 6

The graph so plotted as shown . Answer
