Answer: 1 : -5x + 3y = 2 Equation 2 : -5x - 5y = -30 Because both equations the system of equations by elimination.
Answer:
Neither
Step-by-step explanation:
step 1
Verify if the lines are parallel
we know that
If two lines are parallel, then their slopes are the same
In this problem the slope of f(x) =2/7 and the slope of g(x)=7/2
Compare
2/7≠7/2
therefore
The lines are not parallel lines
step 2
Verify if the lines are perpendicular
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
In this problem the slope of f(x) =2/7 and the slope of g(x)=7/2
Multiply
2/7*7/2=1
1≠-1
therefore
The lines are not perpendicular
Let's break it up into 2 figures, the rectangle on the right with dimensions 3 x 10, and the rectangle on the left with dimensions 8 x 6.
A = 3 x 10
A = 8 x 6
A = 30
A = 48
The sum of these two, 78, will represent the area of the total figure.
Answer:
Step-by-step explanation:
8y + 11 = 4(y - 2)
8y + 11 = 4y -8
subtract 4y from both sides
4y + 11 = - 8
subtract 11 from both sides
4y = -11
divide by 4 on both sides
y = -2.75 or - y = 2.75
if you need a fraction it would be 2 3/4
