Step-by-step explanation:
you need to get 180 right solve it from there
Answer:
-1.023 + 5.6 = 4.58
Step-by-step explanation:
1. Drop the 3 in -1.023, becoming -1.02
2. Add 0 at the end of 5.6, becoming 5.60
3. Here is the problem you now solve:
-1.02 + 5.60. You can simply type this into your calculator. I hope this helped.
I would personally take the number three and trow it out the window but that's not what we are talking about

Answer: The solution is the ordered pair (1/2, -3/4) so x = 1/2 and y = -3/4 pair up together. The two lines, when graphed, cross at this location.
note: 1/2 = 0.5 and -3/4 = -0.75; so the intersection point can be written as (0.5, -0.75)
===================================================
Explanation:
The second equation has y isolated. We can replace the y in the first equation with the expression 1/2x - 1
3x + 2y = 0
3x + 2( y ) = 0
3x + 2( 1/2x - 1) = 0 ... y is replaced with 1/2x-1
3x + 2(1/2x) + 2(-1) = 0 .... distribute
3x + x - 2 = 0 .... note how 2 times 1/2 is 1
4x - 2 = 0
4x = 2
x = 2/4
x = 1/2
Use this x value to find the y value it pairs with
y = (1/2)*x - 1
y = (1/2)*(1/2) - 1 ... replace x with 1/2
y = 1/4 - 1
y = 1/4 - 4/4
y = (1-4)/4
y = -3/4
