Answer:X=4
Step-by-step explanation:
Congruent triangles method
AB/DB=BC/EC
10-x+x/10-x=3+2/3
10/10-x=5/3
30=50-5x
30-50=-5x
-20=-5x
X=4
A conjugate angle is 360°, 360-70=290!
Answer:
y = -2x -1
Step-by-step explanation:
slope intercept form is y = mx +b
m = slope, b = y intercept
point is given as ordered pair (x,y)
plug in slope into y=......
y= -2x+b
plug in the point
3 = -2 * (-2) + b
3= 4 +b subtract 4 on each side
b = -1
y = -2x -1
