(f + g)(x) means f(x) + g(x)
So, you just input the function of f(x) and g(x) altogether, then simplify it.
(f + g)(x)
= f(x) + g(x)
= 2x² + 1 + x² - 7
= 2x² + x² + 1 - 7
= 3x² - 6
The answer is b
Answer:
Step-by-step explanation:
<u>Area formula</u>
<u>Applied to the given rectangle, we have</u>
<u>Since 36 ≤ A ≤ 72, substituting A</u>
It is viable.
Answer:
1). 9 red 6 fancy 2). 50 shirts 20 pants 3). 62 purple 31 red 4). 19 dimes 9 quarters
Step-by-step explanation:
Most are systems of equations. So, they will have more than one equation.
1). x (Red wrapping paper) y (fancy print paper)
x + y = 15
2x + 4y = 42
Solved: x = 9 y = 6
2). x (shirts) y (pants)
x + y = 70
12x + 30y = 1200
Solved: x = 50 y = 20
3). x (purple) y (red)
I ended up dividing 93 by 3 and then multiplying it by 2 for purple and keeping the other third for red. Not quite sure how to fit this into an equation, its just simple math.
Solved: x = 62 y = 31
4). x (dimes) y (quarters)
.10x + .25y = 4.15
x = y - 10
Solved: x = 19 y = 9
Depending on what type of problem your looking for
Ex: units, rates, number lines
Srry don’t really have one in mind
Answer:
15,831.957504
Step-by-step explanation:
30,000*.88=26400
26400*.88=23232
23232*.88= 20,444.16
20,444.16*.88= 17,990.8608
17,990.8608*.88= 15,831.957504
