Answer:
y+2=1/2(x+1)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-2))/(3-(-1))
m=(0+2)/(3+1)
m=2/4
m=1/2
y-y1=m(x-x1)
y-(-2)=1/2(x-(-1))
y+2=1/2(x+1)
Answer: The X intercepts are 5 and -3/2
3 because 21/3 is 7. 24/3 is 8. And 27/3 is 9.
Answer:
The height of the tower=2,702 feet
Step-by-step explanation:
The angle of elevation is the angle between the horizontal level ground and the hypotenuse. Since we have the horizontal distance, we can use this to estimate the vertical height from the base of the tower using the expression below;
Tan∅=h/b
where;
∅=the angle of elevation
h=vertical height of the tower
b=the distance from the base of the tower to the point on level ground
In our case;
∅=27.1°
h=unknown
b=5280 feet
replacing;
Tan 27.1=h/5280
h=5,280×Tan 27.1
h=2,701.91 feet
2,701.91 to the nearest foot=2,702 feet
The height of the tower=2,702 feet
Use substitution
y = 2(-y + 6)
y = -2y + 12
3y = 12, y = 4
4 = 2x, x = 2
Solution: x = 2, y = 4
