Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -2x + 3
g(x) = 2x + 3
f(3) is x = 3 for function f(x)
g(7) is x = 7 for function g(x)
<u>Step 2: Solve</u>
- Substitute in <em>x</em> [Functions]: f(3) = -2(3) + 3, g(7) = 2(7) + 3
- Substitute in functions: f(3) + g(7) = -2(3) + 3 + 2(7) + 3
- Multiply: f(3) + g(7) = -6 + 3 + 14 + 3
- Add: f(3) + g(7) = -3 + 14 + 3
- Add: f(3) + g(7) = 14
Use the law of cosines. c^2= a^2 + b^2 - (2ac*cos (C))
Answer:
C) 155
Step-by-step explanation:
all these angles add up to 360, so --
25 + 34 + 146 + m<9 = 360
205 + m<9 = 360
m<9 = 155, C)
Here are the numbers of times 11 people ate out last month. 4, 6, 6, 5, 7, 4, 4, 5, 4, 5, 5 Find the modes of this data set. If

Answer:
4, 5
Step-by-step explanation:
put in order form least to greatest
4,4,4,4,5,5,5,5,6,6,7
whichever number occurs the most is the mode, if two numbers occur the same amount of times, they are bith the mode.
