Answer:
The nearest ten thousand is 80,000.
Hi there!
Since the triangle is equilateral, all of its sides are congruent. This means that to solve, we can set the two given equations equal to each other.
2(x - 8) = 1/2x + 8
2x - 16 = 1/2x + 8
1.5x - 16 = 8
1.5x = 24
x = 16
Now that we know what x is, we can plug that in for x in the equation for ZY.
2(16 - 8) = ZY
ZY = 2(8)
ZY = 16 units
And here is the work to show that XZ is also 16.
1/2(16) + 8 = XZ
XZ = 8 + 8
XZ = 16
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
<u>Answer
</u>
-1 x + 2y = 4
<u>Explanation
</u>
The first step is to get the gradient of the line.
The two points in the line are; (4,0) and (0,2).
slope = (2 - 0)/(0 - 4)
= 2/-4
= -1/2
To get the function we use one of the point (0,2) and a general point (x,y).
1/2 = (y - 2)/(x - 0)
1/2 = (y - 2)/x
(1/2)x = y -2
x = 2y - 4
x - 2y = -4
-1 x + 2y = 4
2/7 = 630/x
2x = 7 × 630
2x = 4410
÷ 2
2205 = x
