How do you find how many solutions a equation has?

Mathematics
1 answer:
Evgen [1.6K]3 years ago
6 0

Answer:

If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.

What is the equation in point−slope form of the line passing through (−2, −5) and (2, 3)?
Viefleur [7K]

(-2,-5)(2,3)

slope(m) = (3 - (-5) / (2 - (-2) = (3 + 5) / (2 + 2) = 8/4 = 2

There can be 2 answers for this...

y - y1 = m(x - x1)

slope(m) = 2

(-2,-5)....x1 = -2 and y1 = -5

sub

y - (-5) = 2(x - (-2) =

y + 5 = 2(x + 2) <== this is one of them


y - y1 = m(x - x1)

slope(m) = 2

(2,3)...x1 = 2 and y1 = 3

sub

y - 3 = 2(x - 2) <== this is the other one

Please help me
____ [38]
This is pretty weird: ax+ b > c is equivalent to ax + b > 0, for instance. c might always be chosen as zero, or b, or any value!

280x <= 348.76, or -280x + 348.76 >= 0,

so a = -280, b = 348.76 and c = 0 is one solution

I need help with this question

Answer: 5x - 1 = -6

Step-by-Step Explanation:

We have this diagram here showing numbers and symbols. Just a remainder, "X" is a variable which can be found through and equation of Algebra. Alright, so we have 5 boxes with the symbol "X". Alright, that's a start, so we have <u>5x</u> as a start of the equation. We have <u>-1</u> on the same side as well.

Alright, so on the other side- we have Six symbols of "-1".

That concludes to... <u>-6</u>. Alright, notice how all of the symbols are on a Scale, so we can heavily imply that the "=" symbol will take place between the two sets of symbols. Alright, combining them we get.. <u>5x - 1 = -6.</u>

<em>If you need further instructions/help, don't hesitate to give me a shout out. Bye, and I hope this helps.</em>
