Answer:
so the equation is y=-2x-4
Step-by-step explanation:
sub the points in the equation to find the y-intercept
y=x(-2)+b
0=-2(-2)+b
0=4+b
0-4=b
-4=b
Answer:
21 windows
Step-by-step explanation:
colleen's family plans to paint the windows of their house. her father will paint twice as many windows as her mother, and Colleen and her 2 brothers will paint an equal number of the rest of the windows. Colleen decided to do her own share and her mother's share and paints 7 window, which is one less than her father's share. how many windows are in their house?
Answer: Let the number of window Colleen father would paint be x while that of her mother be y. Since her father will paint twice as many window as her mother, therefore the number of windows painted by the father x = 2y
Let the number of windows each painted by Colleen and her 2 brothers be z since they would paint the same number of windows. The total number of windows to be painted = 2y + y + z + z + z = 3y + 3z = 3(y + z).
Then number of windows needed to be painted by Colleen and her mother is given as z + y. Since Colleen painted 7 windows as her share and her mother share i.e. y + z = 7
Therefore the total number of windows = 3(y + z) = 3(7) = 21 windows
Answer:
You are correct
Step-by-step explanation:
Answer: 2 + (0.75m) = 4.25
Step-by-step explanation:
0.75m represents 0.75 * mile. So, you need to also add the flat fee.
You can build a cylinder in two ways: either you draw a circle on a plane, and "raise" it perpendicularly to the plane itself, or you start with a rectangle, and rotate it around one of its sides.
For these reasons, if you cut the cylinder with a plane parallel to the base you have a circular cross section, while if you cut the cylinder with a plane perpendicular to the base you have a rectangular cross section.
