Answer:
option 1 and 4
Step-by-step explanation:
The elimination method should be used when there are two variables with the same number in front of them but different signs.
In the first system, the first equation has -8y while the second one has 8y.
Both equations have an 8y with different signs therefore using the elimination method would be most logical.
In the fourth system, the first equation has a -4x while the second one has 4x.
Both equations have 4x with different signs therefore using the elimination method would be most logical
Reasons it can't be the other options :
In the second system, no variable has the same number before it so no variable can be eliminated unless you multiply the equations by a common multiple. The best method for this system would be graphing
In the third system y is defined by an expression therefore using the substitution method is the most logical approach.
The answer is 25/400 because it is 25 green marble and it 400 in all
Answer:
Step-by-step explanation:
Use the point-slope formula by the line
y - y_1 = m(x - x_1) when x_1 =8 and y_1 = -2 m : is the slope (same slope for the line whose equation is 3x + 4y = 15 because are parallel)
calculate : m
3x + 4y = 15
4y = -3x +15
y = (-3/4)x +15/4 so m = -3/4
an equation is : y +2 =(-3/4)(x-8)
