Remember the angles add to 180, so 27 + 27 + x = 180

54 + x = 180
x = 126

Answer:

The solution is (4, 0)

Step-by-step explanation:

Using Linear combination method to solve:

$2d + e = 8\\d - e = 4\\$

Since "e" have the same coefficient in both equation with opposite operator; we will add.

$(2d + d) + (e - e) = (8 + 4)\\3d = 12\\$

Divide both side by coefficient of d which is 3

$\frac{3d}{3} = \frac{12}{3} \\d = 4\\$

Since d = 4; put 'd' into any of the equation to get 'e'

$2d + e = 8\\2(4) + e = 8\\8 + e = 8\\e = 8 - 8\\e = 0\\$

Therefore, the solution is (4, 0)

After which value of x does function g exceed function f

nalin [4]

We have that

for x=1
f(x)=1.5 and g(x)=-1
so
g(x) < f(x)

for x=2
f(x)=5 and g(x)=5
so
g(x)= f(x)

for x=3
f(x)=9.5 and g(x)=23
so
g(x) > f(x)

therefore

the answer is
<span>After x=2 function g exceeds function f</span>
