A system of linear equations with no solution means that the lines never meet. So as long as your two lines have the same slope and different intercepts, they will be parallel.
Ex.) y= 2x + 5
and y=2x + 10
to have a solution, the lines have to cross at a point. so literally any two lines that aren't parallel.
Ex.) y= 3x + 1
to find the solution you start by setting the equations equal to each other
2x + 5 = 3x + 1
1) subtract 2x from both sides
5= x + 1
2) subtract 1 from both sides
4 = x
now we know the x value of the point is 4. To find the y value plug 4 into one of the equations
2(4) + 5
8 + 5
13
so the solution to this particular system is (4,13)
Answer:
p=7 and r=2 and they both = a total of 23.
Step-by-step explanation:
7p+2r=23
Add all the numbers up, and divide by how many numbers you added up.
-3 + 4 + 7 + 2 + 5 + 9 = 24
You added up 6 numbers, now divide 24 by 6.
24 ÷ 6 = 4
Well, I actually did the entire calculations until I figured out that its very simple, and I didn't need to!
If she has already saved 6%, then to find how much she still needs to save, we subtract 100% from 6%.
So Nina still has to save 94% of the total cost to get the bike.
Answer:
25
Step-by-step explanation:
(4 - (-3)^2)^2
(4 - 9)^2
-5^2
25
I hope this helps,and sorry if it is wrong.but im pretty sure its right
