First, I would isolate the y to make it easier
7y=-4x-5
y=-4/7x-5/7

Since there are basically and infinite amount of solutions to this equation, I would plug in both a 4 and -4 for x in the equation and solve for y

y=(-4/7)(4)-5/7
y=-16/7-5/7
y=-21/7, or -3

So since (4,-3) is a choice, the answer is C

Hope this helps

The answer is C because 4(4)+7(-3)=-5.

A license plate has six characters. Three characters are letters, two characters are numbers (0-9), and one character is a lette
jok3333 [9.3K]

Answer:1)Number of different license plates can be made =17576×100×260=456976000

2)Probability of getting a plate with abc123 or 123 abc=0.0000004

Given that :-A license plate has six characters.

As three characters are letters ∴ ways of these 3 letters into the plate with repetition = 26×26×26=17576 ways

and  two characters are numbers (0-9 - total 10 characters)∴ways of these 2 numbers into the plate with repetition=10×10 =100 ways

and one character is a letter or a number=26×10=260

So number of different license plates can be made =17576×100×260=456976000

Now Probability of getting a plate with abc123 or 123 abc

=P(abc123 or 123abc)=P(abc123)+P(123abc)-P(abc123)×P(123abc)=1/456976000+1/456976000-1/456976000×1/456976000

=1/456976000(1+1-1/456976000)

=1/456976000(2-0.0000002)=2/456976000=0.0000004

Probability of getting a plate with abc123 or 123 abc=0.0000004
