Answer:
(1/2, -1.8) belongs in quadrant 4
quadrant 4 is a (positive, negative)
Answer:
x=1 y = -1/2
(1,-1/2)
Step-by-step explanation:
7x-2y=8
5x+2y=4
I would use elimination since we have 2y in one equation and -2y in the other
7x-2y=8
5x+2y=4
--------------------
12x = 12
Divide each side by 12
12x/12 = 12/12
x =1
The substitute back into equation 2
5(1) +2y = 4
5 +2y = 4
Subtract 5
5-5+2y = 4-5
2y = -1
Divide by 2
2y/2 = -1/2
y = -1/2
I just did it on paper but hope that helps:)
Answer: The answer is D. Trapezoid.
Step-by-step explanation: As shown in the attached figure, a rectangular pyramid ABCDE is drawn. We are slicing this rectangular pyramid parallel to the base BCDE at the points F, G, H and I.
We can clearly see from the figure that upper half of the sliced figure will be similar to the pyramid BCDE and the lower sliced figure will be a trapezoid. These are the three-dimensional figures.
Also, the sliced two-dimensional figure FGHI will be a rectangle, because
the pyramid is a rectangular one and so, FI=GH, FG=HI and all the angles are right angles.
Thus, the resulting two-dimensional figure will be a rectagle.
Answer:
Dear Laura Ramirez
Answer to your query is provided below
Option B is correct
Step-by-step explanation:
In a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
Also,
By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.
Here, if you see( 16+24)>38
So, the set of numbers can be measures of a
triangle.
