Multiply: (3x-4)(2x-5)
This comes out to 6x^2 - 15x - 8x + 20
Combine the x terms and you'll be done.
-2x+y=5
x-3y=-30 so you can multiply the bottom equation by 2 you'll get 2x-6y=-60
-2x+y=5
2x-6y=-60 And subtract the equations. You'll get -5y=-55 y=11. Plug it in to one of the original equations. -2x+(11)=5
-2x=-6 so x=3
y=11 and x=3
Answer:
The equation of the line L is 
Step-by-step explanation:
we know that
The line y=7
Is a horizontal line (parallel line to the x-axis)
The slope of a horizontal line is equal to zero
A line L perpendicular to the given line must be a vertical line (parallel to the y-axis)
The slope of the line L is undefined
The line L passes through the point (2,-5)
therefore
The equation of the line L will be equal to the x-coordinate of the given point

40,
since
400 x 4 + 1.6 grams. which is the closest
4 x 10 = 40
Answer:
9.5 inches
Step-by-step explanation:
The radius is 1/2 of the diameter
19/2 = 9.5 inches
