G(f(2)) means work out whatever f(2) is then plug this into g(x).
So f(2) is 3 because we just find the x-value 2 in the left hand column and read across. This is 3.
So then we find g(3) by finding the x-value 3 in the left hand column and read across. This is 10.
So g(f(2)) = 10
So what we can assume from the things given,
m∠A = x
<span>
</span>m∠B = 2x
m∠C = 3x
m∠C + m∠B + <span>m∠A = 180º
x = 30º
Because 30º + 60º + 90º = 180º

Answer:
y = 5x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
5x = y - 4 ( add 4 to both sides )
5x + 4 = y , that is
y = 5x + 4 ← in slope- intercept form
A=p (1+r/k)^kn
A future value
P present value 6000
R interest rate 0.08
K compounded semiannual 2
N time 35years
A=6,000×(1+0.08÷2)^(2×35)
A=93,429.71
