How do you tell if the linear equation is one solution many solution or no solution

Mathematics

If it's a graph: Solutions are points of intersection

The same line means infinitely many solutions

Parallel lines = never intersects = no solution

1 point of intersection = 1 solution

If it's a system of equations:

If you get _*x = _(a number), 1 solution (divide by the coefficient, and get only 1 possible value)

If you get x = x, infinitely many solutions (x can be anything and still equal itself)

If you get two different constants equaling (such as 1 = 2), there is no solution because no value of x can make those two values equal.

twice r plus 7 is equal to 45 minus r  : 2r+7=45-r

Product of h and 4 is subtracted from one-fifth of x is 35 :(h*4) - 1/5*x

Well 32 x 405 is 12,960, but it ask for 2 numbers added to make 12,960 so the answer is 810 + 12,150 which is 2 products that add up to the answer 12,960.

the number n is a 2-digit number. when n i divided by 10, the remainder is 9, and when n is divided by 9, the remainder is 8. wh
larisa [96]
Think of numbers that when they are divided by 10, the remainder is 9.
So numbers like: 19, 29, 39, 49, 59, 69, 79, 89, and 99.

Now numbers that when they are divided by 9, the remainder is 8.
So numbers like: 17, 26, 35, 44, 53, 62, 71, 80, 89, and 98.

Now the number that is alike from the two sets of numbers is n.
n=89

Double check your work.
Divide 89 by 10. Remainder of 9
Divide 89 by 9. Remainder of 8.

Hope this helps :)

Answer:

6 years and 1 month

Step-by-step explanation:

A= Pe^rt

Since you need to find the double A=2P

2P=e^0.1132t

0.1132t=ln 2

0.1132t=0.693

t= 6.12

ps: I think this is right but I'm not sure I had the same problem and I got this.
