Answer:
be spacific
Step-by-step explanation:
because if you arn't people would give you stupid answers
Answer:
well think about it
50 pages = 1 hour (60 mins)
so it would take laine 4 hours in total to read 200 pages at the rate
hope that helps :)

Answer:neither are
Step-by-step explanation:
It’s no
Answer:
use substitution method
find equation for value of x/y
2x + 2y = 4
2y = 4 - 2x
y = <u>4 - 2x</u> ----> equation 1
2
so..substitute the
equation 1 to -5x+3y=-18
-5x+3( <u>4 - 2x</u><u> </u><u>)</u> = -18
2
-5x + 3(2-x) = -18
6-3x = -18+5x
6+18= 5x+3x
24 = 8x
<u>2</u><u>4</u> = <u>x</u>
8
x= 3. -----> eq.2
sub eq.2 into 1 to find the value of x
y = <u>4-2(3)</u>
2
y = - 1
x=3 ; y= -1
Sure... a good example of that is when you have non-linear expressions in the system, like say for example a linear and a quadratic, like y = 4x and y = x².
recall that for a system of equations, where the graph of both equations intersect, is the solutions, check the picture below.
