Answer:
<h2>
</h2>
Step-by-step explanation:
To find g-¹( 2) we must first find g-¹(x)
To find g-¹(x) equate g(x) to y
That's
y = g(x)
We have
y = - 2x + 7
Now interchange the terms that's x becomes y and y becomes x
We have
x = - 2y + 7
Make y the subject in order to find g-¹(x)
Move 7 to the left side of the equation
- 2y = x - 7
Multiply both sides by - 1
We have
2y = 7 - x
Divide both sides by 2 to make y stand alone
That's
<h3>
</h3>
So we have
<h3>
</h3>
Now to find g-¹(- 2) substitute the value of x that's - 2 into the expression
We have
<h3>
</h3>
We have the final answer as

Step-by-step explanation:
Answer:
Last choice is correct.
Step-by-step explanation:
Given that ∠C=90°, ∠B=30°, c=10
We know that sum of all angles in a triangle is 180 degree.
∠A+∠B+∠C=180°
∠A+∠30°+∠90°=180°
∠A+∠120°=180°
∠A=60°
Now we can use sin or cos whichever applicable to find missing sides
2b=10
b=5
Similarly
a=8.6602
Hence last choice is correct.
Well I believe there are line segments and everlasting line as which I believe are just called lines. but I'm not entirely sure I haven't taken geometry in a few years
The statement is FALSE.
A constant term is also a polynomial with just one term and degree 0. The degree of the polynomial can be any non-zero integer i.e. can be 0 or greater than zero.
So the correct statement will be:
An expression must have a monomial of degree 0 or higher to be a polynomial
