Answer:
6. The triangle is acute
m<P = 60
m<Q = 84
m<R = 36
----------------
7. Claim: the three angles added together equal 180 degrees
m<J = 116 degrees
m<K = 33 degrees
m<L = 38 degrees
Step-by-step explanation:
m<P = 4a + 12 = 4(12) + 12 = 60
m<Q = 7a = 7(12) = 84
m<R = 3a = 36
(4a + 12) + 7a + 3a = 180 degrees
14a + 12 = 180
14a = 168
a = 12
----------------
m<J = 4x + 12 = 4(26) + 12 = 116
m<K = x + 7 = 26 + 7 = 33
m<L = 2x - 14 = 2(26) - 14 = 38
(4x + 12) + (x + 7) + (2x - 14) = 180 degrees
7x - 2 = 180
7x = 182
x = 26

What value(s) of x make the following equation true?
2x - 6 = 3x + 1 - 2x - 7
Answers
Answer:
x = 0
Step-by-step explanation:
2x−6=3x+1−2x−7
Step 1: Simplify both sides of the equation.
2x−6=3x+1−2x−7
2x+−6=3x+1+−2x+−7
2x−6=(3x+−2x)+(1+−7)(Here we Combine Like Terms)
2x−6=x+−6
2x−6=x−6
Step 2: Subtract x from both sides.
2x−6−x=x−6−x
x−6=−6
Step 3: Add 6 to both sides.
x−6+6=−6+6
x=0

If f(x) = 6x +5 and g(x) = 2x – 7 find (fºg)(x)
Answers
Answer:
f(g(x)) = 12x - 37
Step-by-step explanation:
Step 1: Define
f(x) = 6x + 5
g(x) = 2x - 7
Step 2: Find f(g(x))
f(g(x)) = 6(2x - 7) + 5
f(g(x)) = 12x - 42 + 5
f(g(x)) = 12x - 37

What is the inverse function of f(x)= x/x-2
Answers
Explanation:
Setting y=f(x)
y=x/x-2
This may be rearranged as follows
y(x-2) = x
x•y-2y = x
x•y-x = 2y
x=2y/y-1
The expression shows x in terms of y.
That is it! The inverse function of f(x).
