Answer:

Step-by-step explanation:

The distance from Q to S is 2 - (-14), or 16.

We start at point Q.  Note how 3 and 5 add  up to 8, which allows us to write:

R = Q + (3/8)(16), or R = -14 + 6, or R = -8.

From R to S it is (5/8)(16), or 10 units.

The directed line segment is partitioned into segments of lengths 6 and 10, whose combined length is 16, as expected.

How do you solve 16 = 17 - t
Ivanshal [37]

So I looked it up on another math helper app called ( Socratic )and this is what popped up on my screen Simplifying

16 = 17 + -1t

Solving

16 = 17 + -1t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add 't' to each side of the equation.

16 + t = 17 + -1t + t

Combine like terms: -1t + t = 0

16 + t = 17 + 0

16 + t = 17

Add '-16' to each side of the equation.

16 + -16 + t = 17 + -16

Combine like terms: 16 + -16 = 0

0 + t = 17 + -16

t = 17 + -16

Combine like terms: 17 + -16 = 1

t = 1

Simplifying

t = 1

So I’m pretty sure that’s the answer:) if not I’m truly sorry.

-x-3y=14<br> x=4y<br><br><br> solve using substitution
vlabodo [156]
Using
 f1(x)= -x=3t =14

with f2(x) as x=4y

f1(f2)= -x-3y=14
F1(4y)= -(4y)-3y=14
           = -4y-3y=14
           = - 7y=14
           = y= -2

Using the value of y, solve fo rx by entering the value in the original form of f1 or f2

<span>-x-3y=14</span>
-x-3(-2)=14
-x+6=14
x=-8

OR
x=4y
  =4(-2)
  = -8

Thus the solution is (x,y) = (-8,-2)
