Answer:
Y=40
X=67
Step-by-step explanation:
In a cross line problem, one part of the cross, (such as 63°) is always the same on the other side. (like y+23° and 63°. This means Y=40 because 40+23 is 63.
To find x, you must know that 360° is all the way around in degrees. you know that 126° (63 +63) is already taken up. So you subtract 126 from 360 and then multiply the answer by 1/2 because you trying to find the bottom total.(360-126)=234(1/2)= 117 Lastly, you find X in the equation 2x-17=117.
x=67
Answer: No real solution.
Step-by-step explanation:
Since the parabola never crosses the x-axis, there are no real solutions.
Slope = (-12 - 43)/(4 +7) = -55/11 = -5
y = mx + b
43 = -5(-7) + b
43=35+b
b = 8
equation
y = -5x + 8
Answer:
I suppose you mean 999^2
(1000-1)^2
which comes under the identity
(a-b)^2=
(a^2 + b^2 - 2ab)
hope this helps
