Answer:
(5,-4)
Step-by-step explanation:
If reflected over the x-axis, the quadrilateral would be in the fourth quadrant. N' would be at (1,-1) and P' at (6,-1). To reflect, look at the y-coordinate of the point and turn it to negative. With point Q, it's at (5,4) so we just flip the 4 to -4 and that's our point! (5,-4)
Answer: x=-35/10
y=-4
Step-by-step explanation:
y = 3/2x +5/4
-2x+8y=-25
--------------------
replace y in second equation with: y = 3/2x +5/4
-2x+8(3/2x+5/4)= -25
-2x+12x+10= -25
10x=-35
x=-35/10
x=-3.5
7+8y= -25
8y=-32
y=-4
Answer:
you divide 13 by four and you get 3 and a quarter. thats your answer
Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
The ratio A/r² would represent
which is the circumference of a circle divided by its diameter.
You can see this because the area of a circle is
r² and if you divided that by the radius squared, you are given pi which is the circumference of a circle divided by its diameter.
