The formulae for the midpoint are correct:

M ( (x₂-x₁)/2 , <span>(y₂-y₁)/2 )

You need to invert these to get x</span>₁ and y₁:
x₁ =2xm - x₂
y₁ =2ym - y₂

Try with the x to prove the formulae are correct:
x<span>₁ =2·(-8) - (-6) = -16 + 6 = -10  which is what we have!

Then, use</span> the other formula for y:
<span>y₁ =2 ·(6) - (7) = 12 - 7 = 5

Therefore y</span>₁ = 5

Answer: d is 53 degrees, c is 5, g is 13, e is 90 degrees, f is 37 degrees, b is 12 .

Step-by-step explanation:

Since they're congruent you just compare the two and replace them. You have the answers on both sides, they're just split up. So look at one side, then the other, and see what you can find. Repeat.

Answer:

A: f(x)\leq -2

Step-by-step explanation:

After graphing the equation, the highest point is (-1,-2). Since f(x) is the 2nd number in the coordinates (x, f(x)), the range is f(x)\leq -2

Is 5/8 more than 11/20
alexdok [17]
5/8 is more than 11/20

If we find the lower common multiple of the denominators which is 160 then we can multiply the top numerators by the opposite denominators

5x20=100
11x8=88

We now have
\frac{100}{160}  and  \frac{88}{160}

The one on the left is simplified to 5/8 and the right is simplified to 11/20
