Mathematics
1 answer:
hoa [83]3 years ago
3 0

Answer:

1.  y=-x

2. y=-3/2x-2

3. x=4

4. y=-2x-1

Step-by-step explanation:

slope intercept form is y=mx+b with mx being the slope and b being the y intercept

if its parallel it has to have the same slope.

perpendicular lines have the opposite slope and sign. so if its a whole number you put it over 1 and if its a fraction you switch the values in the numerator and denominator in addition to changing the sign. You keep the y intercept the same.

What does x equal in this equation: 24+3x=3x+3(7-1) Please help this is due tomorrow!
Zinaida [17]

                                              24 + 3x = 3x + 3(7 - 1)

Eliminate the parentheses:    24 + 3x = 3x + 3(6)

                                              24 + 3x = 3x + 18

Subtract  3x  from each side:       <em>24  =  18</em>

Look at that for a second.  Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.

That's just another way to say: "The equation has NO solution."
