Answer:
1. 142. 2. adjacent angles.
Step-by-step explanation:
1. because it is less then 180, that would be flat, and it is bigger then 132.
2. because they are adjacent to each other.

Step-by-step explanation:
f(x) = 9x³ + 2x² - 5x + 4; g(x)=5x³ -7x + 4
Step 1. Calculate the difference between the functions
(a) Write the two functions, one above the other, in decreasing order of exponents.
ƒ(x) = 9x³ + 2x² - 5x + 4
g(x) = 5x³ - 7x + 4
(b) Create a subtraction problem using the two functions
ƒ(x) = 9x³ + 2x² - 5x + 4
-g(x) = <u>-(5x³ - 7x + 4)
</u>
ƒ(x) -g(x)=
(c). Subtract terms with the same exponent of x
ƒ(x) = 9x³ + 2x² - 5x + 4
-g(x) = <u>-(5x³ - 7x + 4)
</u>
ƒ(x) -g(x) = 4x³ + 2x² + 2x
Step 2. Factor the expression
y = 4x³ + 2x² + 2x
Factor 2x from each term
y = 2x(2x² + x + 1)

Answer:
a = 7
b =?
c = 1/2
a + by = 0
7 + b × 1/2 = 0
7 + 1/2 b = 0
1/2 b = - 7
b = -7 × 2
b = - 14
a + by
= 7 + - 14 × 1/2
= 7 -14/2
= 7 - 7
= <u>0</u>
Step-by-step explanation:
Id.k if you forgot to write the value of b or not, since the value of b is not given, this will be ur answer.
Answer:
<em>The answer is a = 6.</em>
