+-(1,7)/+-(1,3,9) are the combinations of f(x)
Answer:
Let's define the variables:
M = number of books that Marcus has.
x = number of books that Jessie has.
We know that:
"Marcus has one book less than three times the number of books that Jessie has."
Then the equation that represents the number of books that Marcus has is:
M = 3*x - 1.
Then if x tiles represent the number of books that Jessie has, the number of tiles for Marcus will be 3 times that, and then subtract one tile.
Answer:
a rectangle
Step-by-step explanation:
1. a quadrilateral has 4 sides. this has 4 sides. this is a quadrilateral
2. a parallelogram has (a) opposite sides and (b) opposite angles of equal length. here, all sides are equal so (a) can be checked off. opposite angles are also equal so (b) can be checked off
3. a rhombus has 4 sides of equal length. all 4 sides are of equal length so this is a rhombus
4. a rectangle has 4 right angles. the angles here are not perpendicular to each other. thus, right angles are not formed and this is not a rhombus
Answer:
Step-by-step explanation:
slope of line through (6,-1) and (11,2) = (-1 - 2)/(6 - 11) = 3/5
slope of line through (5,-7) and (8,-2) = (-7 - (-2))/(8 - 5) = -5/3
product of the slopes = -1, so the lines are perpendicular.
