Answer:
The answer to your question is below
Step-by-step explanation:
f(x) = 2x + 5
To solve letter a, just multiply each term of f(x) by 3 and subtract 2.
a) 3f(x) - 2 = 3(2x + 5) - 2
= 6x + 15 - 2
= 6x + 13
To f(x) subtract twice g(x)
b) f(x) - 2g(x) = 2x + 5 - 2(x² - 3x + 2)
= 2x + 5 - 2x² + 6x - 4
= -2x² + 8x + 1
Multiply 5 by each term of f(x) and divide it by g(x)
c)
=
Answer:
45
Step-by-step explanation:
The sum of angle in a straight line is 180
=> 3n + (4n - 15) + 90 = 180
3n + 4n + 75 = 180
7n = 180 - 75 = 105
n = 15
Angle ZLQK = 4n - 15 = 4*15 - 15 = 60 - 15 = 45
The coefficient (letter chosen) that is used does not matter as it is only to show that it is an unknown variable, if you have more than one variable you need more than one type of coefficient (use different letters for different ones you dont know).
Answer:
64
Step-by-step explanation:
x-13+2x+1=180
3x-13+1=180
3x-12=180
3x=180+12
3x=192
x=192/3
x=64
