A) Tan(38) = x/6
x = 6*Tan(38)
x = 4.69
b) Tan(75) = x/13
x = 13*Tan(75)
x = 48.52
9 feet and 1 inch is your answer
Answer:
(-5,1)
Step-by-step explanation:
y=3x+16
4x-5y=-25
substitute the given value of y into the equation.
4x-5(3x+16)=-25
solve
x=5
substitute the given value of x into the equation.
y=3x(-5)+16
solve
y=1
(-5,1)
Remember, you can do anything to an equation as long as you do it to both sides
0.6x-10=1.4x-(-14)
and minusing a negative means adding
0.6x-10=1.4x+14
minus 0.6x from both sides
0.6x-0.6x-10=1.4x-0.6x+14
0-10=0.8x+14
-10=0.8x+14
minus 14 both sides
-14-10=0.8x+14-14
-24=0.8x+0
-24=0.8x
multily both sides by 10
-240=8x
divide both sides by 8
-240/8=(8x/8)
-30=(8/8)x
-30=1x
-30=x
x=-30
