Answer:
ordered pair(-2 , 3) is the solution
Step-by-step explanation:
y=x+5
y=-2x-1
x+5 = -2x-1 substitution
x+5+2x-5 = -2x-1+2x-5
3x = -6
x = -2
y = -2+5 = 3
ordered pair(-2 , 3) is the solution
Answer:
10.44 m
Step-by-step explanation:
Solve this as a triange. The base is 3m and the perpendicular is 10m. The angle between the base and wall is 90° so it will be a right angled triangle.
Solve this by Pythagoras theorm:
let length of ladder is c
base is b
And perpendicular is a
Acc to Pythagoras theorem:
C² = a² + b²
C² = 10² + 3²
C² = 100 + 9
C² = 109
√C² = √109
C = 10.44m
