Answer: altitude at starting point is -11ft or 11ft below sea level
Step-by-step explanation:
Equation for this situation will be
A = Ag - 11
A = actual altitude
Ag = altitude gained.
At starting point, altitude gained is zero, therefore;
A = 0 - 11
A = -11ft
Answer:
2A/ (b1-b2) =h
Step-by-step explanation:
A = 1/2 (b1-b2) *h
Multiply each side by 2
2A = 2 *1/2*(b1-b2) *h
2A = (b1-b2) *h
Divide by (b1-b2)
2A/ (b1-b2) = (b1-b2)/(b1-b2) *h
2A/ (b1-b2) =h
I'm going to use the substitution method.
If y = - 3/2 - 7, then:
1/2x + 5 = - 3/2x - 7
Combine like terms:
4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)
Simplify to get:
x = - 6.
Plug - 6 back in for x in either equation.
Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.
X = - 6, Y = 2
