The missing reason in step 8 is the substitution property.
<h3>What is substitution property?</h3>
It should be noted that according to substitution property, if x = y, then x can be substituted for y in any equation.
When a variable is equal to another variable, then the variables can be interchangeable.
In this case, the missing reason in step 8 is the substitution property.

Answer:
f(0) = g(0)
Step-by-step explanation:
- if a function h(x) passes through [a,b] then it can be said that h(a)=b.
- given that, g(x) passes through (-2,0) and (0,4)
so, g(-2)=0, g(0)=4.
- f(x) passes through (0,4) and (2,0)
so, f(2)=0, f(0)=4.
- so, first option is correct.
Answer:
17.9°
Step-by-step explanation:
From trigonometry:
Opposite = 14
Adjacent = x
theta = 38°
hence;
tan theta = opposite/ adjacent
tan38° = 14/x
x = 14/tan38°
x = 17.9°

Answer:
-2497
Step-by-step explanation:
Sn=n/2[2a+(n-1)d]
=22/2[2*-40+(22-1)d]
=11(2*-40+(21*-7)
= -2497
