Answer:
im pretty sure #9 is just y=7x... it should be parallel with y=7x-3 since it has y intercept of 0 rather than -3.
Given:
Parallelogram length = 11 cm
triangle atop the parallelogram : short leg = 7 cm
Right triangle inside the parallelogram : long leg = 9cm
Area of parallelogram = base * height
A = 11cm * 9cm
A = 99 cm²
Area of a triangle atop the parallelogram:
A = ab/2
A = (11cm * 7cm)/2
A = 77 cm² / 2
A = 38.5 cm²
Total area of the figure
99 cm² + 38.5 cm² = 137.5 cm²
Answer:
(d) (7, -5)
Step-by-step explanation:
The x-coordinate is listed first in an ordered pair. It is found on the horizontal scale. The point is on the grid line halfway between 6 and 8, so is presumed to have an x-coordinate of 7.
The y-coordinate is listed second in an ordered pair. It is found on the vertical scale. The point is on the grid line halfway between -4 and -6, so is presumed to have a y-coordinate of -5.
The coordinates of point A are (x, y) = (7, -5).

<em>Additional comment</em>
As in the case here, you will often run across graphs that don't have markings on every grid line You are expected to be able to figure out the value of a grid line based on the spacing of the marked lines.
It is a good idea to get familiar with reading coordinates of a point on a graph, as you will be doing it a lot.
<span>What
is $22 marked up to $33
Ok, let us first analyze the given problem.
=> 22 dollars is said to be the original amount of money.
=> 33 dollars is the total marked up amount.
Now, we need to find out how many percent did the money increased
Solutions:
=> 33 dollars - 22 dollars = 11 dollars
=> 11 dollars / 22 dollars = 0.5 dollars
=> 0.5 dollars * 100% = 50%
Thus, the marked up money is 50%
