Answer:
(-3, -6)
explanation:
When reflected across x axis, the x value will be same and y value will become negative.
original coordinates of D: (-3, 6)
- so new coordinates: (-3, (-)6) = (-3, -6)
One
The sum of two rational numbers is always rational. sqrt(9) + sqrt(25) = 3 + 5 which is rational. sqrt(16/100) = 4/10 = 2/5 is also rational. 3/28 is rational as well.
Two
Those are irrational. sqrt(10) + pi = ???? You cannot reduce this to any kind of fraction. Two irrationals always give a rational.
Three
The irrational number controls the answer. 10 + sqrt(5) is irrational. The 10 is OK. It is raional, but sqrt(5) is not a rational number.
Answer:
x=125
Step-by-step explanation:
all angles of a triangle add up to 180 degrees.
30+25=55
180-55=125
Answer:
y= 2x+4
Step-by-step explanation:
To find slope its y2-y1/x2-x1
Plug it into any coordinate to get 2x
To find b in y=mx+b, you look at the y at the 0, in this case, "(0,4) Thefore the b is 5
