Without graphing, classify the following system as independent, dependent, or inconsistent. y=-3x+4 and 6x+2y=8

forsale [732]

Answer:

Dependent

Step-by-step explanation:

$y=-3x+4$ and $6x+2y=8$

Lets solve the second equation for y and then substitute it in first equation

$6x+2y=8$

Subtract 6x on both sides

$2y=-6x+8$

Divide by 2 on both sides

$y=-3x+4$

Now we plug it in first equation for y

$-3x+4=-3x+4$

Add 3x on both sides

$4=4$

Both sides are same, they are equal. the system has infinite solutions.

They are said to be dependent

The numerator of a fraction is 15 less than twice its denominator. If the numerator is increased by 5 and the denominator is inc

denis-greek [22]

Answer:

7/11

Step-by-step explanation:

Let d represent the original denominator. Then the original numerator is ...

2d-15

The new numerator is ...

(2d-15) +5

and the new denominator is ...

d+7

The ratio of these is 2/3, so we have ...

$\dfrac{2d-15+5}{d+7}=\dfrac{2}{3}\\\\3(2d-10)=2(d+7) \quad\text{cross multiply}\\\\4d=44 \quad\text{add 30-2d}\\\\d=11\\\\2d-15=2(11)-15=7$

The original fraction is 7/11.
