7x - 4y = -5 ordered pair

Mathematics
1 answer:
Roman55 [17]2 years ago
3 0

Answer:

Step-by-step explanation:

You may invent a value for x, substitute that value into the given equation and thereby calculate y:

If 7x - 4y = -5 and x = 0, then -4y = -5 and y = 5/4.  The corresponding ordered pair is (0, 5/4).  Other x values may be chosen at random and the same operations performed so as to find other possible ordered pairs corresponding to 7x -4y = 5.

HELP ASAP!!!! SO STUCK ON THIS! Will give brainliest IF CORRECT! :) please help! Be sure please!
vlada-n [284]
If I can read the #'s correctly:
add the yes answers together 23+147 = 170
add the no answers together 112+48= 160

so your ratio of haves to have nots is 170 to 160

but both sides can be divided by 10, so it can be simplified to 17 to 16.

Good Luck!
