Multiply, then you get 2a - 10 = -2. Then isolate the variable by adding 10 on both sides. you get 2a = 8. divide both by 2 and you get a = 4
Hello :
tanA = sinA/cosA
cosA = sinA /tanA
cosA =(4/5)/(4/3)
cosA=3/5
I believe 8,000,000. I'm probably wrong though.
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)
-4/3 = (6 - y)/[4-(-2)]
-4/3 = (6-y)/6
(-4/3)×6 = 6-y
-8 = 6-y
y = 6 + 8
= 14
H=henry's age
j=justin's age
h=10j
in 6 years (h+6 and j+6)
h+6=4(j+6)
the equations are
h=10j and
h+6=4(j+6)
C is answer
