Answer:
1) c, f
2) a, e
3) b, d
Step-by-step explanation:
If you think about the units associated with a coordinate (feet, for example), then you may recognize the following
a) each difference is of "feet", so each difference will have units of "feet". The ratio of "feet" to "feet" cancels the units, leaving a pure number. In this case, it is called "steepness" in selection e. Steepness is given by the slope formula (2).
__
b) The difference in parentheses has units of "feet" (as in (a)), so the square will be "square feet". The sum of two of those will still be "square feet" and the square root of that will be "feet". The units of the formula are those of distance, or length, matching selection d. Distance is given by the distance formula (3).
__
c) The form shown is an ordered pair. That is the same as the representation of a coordinate point, selection f. Coordinates of a point are given by the midpoint formula (1).
Answer:
(x+5)² + (y+6)² = 12.25
Step-by-step explanation:
Answer:
Step-by-step explanation:
In the line segment..
Combine like terms.
Add -2 to both sides.
Subtract 9x from both sides.

1. Find the area of the triangle by using 1/2 bh.
1/2 (34)(15)=255
2. Find the area of the rectangle by using bh.
(10)(24)=240
3. Subtract the areas.
255-240=15
You find that the area of the shaded area is 15
If you would like to know what is the solution for the system of equations, you can calculate this using the following steps:
y - x = - 3
y + x = 3
_______________
y - x + y + x = - 3 + 3
2y = 0
y = 0
<span>y - x = - 3
</span>0 - x = - 3
x = 3
(x, y) = (3, 0)
The correct result would be D. (3, 0).
