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
H(8) = ( 8 + 3 ) 2 + 4 = ( 11 ) 2 + 4 = 22 + 4 = 26
The number of the blue marbles are in the box will be 102.
<h3>What is the solution of the equation?</h3>
The solution of the equation means the value of the unknown or variable.
A box contains 162 marbles which are either red (r) or blue (b).
r + b = 162 ...1
There are 42 more blue marbles than red marbles.
b = r + 42 ...2
Then from equation 1 and 2, we have
r + r + 42 = 162
2r = 120
r = 60
Then the number of blue marble will be
b = 60 + 42
b = 102

Answer:
graph y=12x-10-3 has a larger slope and does not pass through the origin, however, y=1x has a smaller slope and passes through the origin
Step-by-step explanation:
If you graph these lines it will help you to visually see this also. My graph is not exact but I hope it is helpful!
