Answer:
C. 77x⁷ + 78x⁶ - 27x⁵
Step-by-step explanation:
Operation of functions
f(x) g(x)
f(x) • g(x) = (11x³ - 3x²)(7x⁴ + 9x³)
Simplify or expand
(11x³ - 3x²)(7x⁴ + 9x³)
Expand the expression
11x³ × 7x⁴ + 11x³ × 9x³ - 3x² × 7x⁴ - 3x² × 9x³
Multiply
77x⁷ + 99x⁶ - 21x⁶ - 27x⁵
Combine like terms
77x⁷ + 78x⁶ - 27x⁵
Hope this helps and have a nice day
The width is the x-value, meaning that the constant has to be divided by the x-value to get the y-value (height), so take (5,20) for example.
The equation would be 20=(x/5). Multiply both sides by 5 to get x by itself. This gives you that x=100. The constant is 100.
Therefore, the answer is C: 100.
Just add them all up that’s it and you will get 20
Answer:
(- 5, 5 )
Step-by-step explanation:
5x + 7y = 10 → (1)
- 9x + y = 50 ( add 9x to both sides )
y = 9x + 50 → (2)
substitute y = 9x + 50 into (1)
5x + 7(9x + 50) = 10
5x + 63x + 350 = 10 ( subtract 350 from both sides )
68x = - 340 ( divide both sides by 68 )
x = - 5
substitute x = - 5 into (2)
y = 9(- 5) + 50 = - 45 + 50 = 5
solution is (- 5, 5 )
Answer:
2,267.9g
Step-by-step explanation:
2,267.9g is more precise than 2,268 g becasue it is providng the actual number, with decimals. It is providind the most accurate weight, showing that it's just a tiny bit less than 2,268 g, but still has the exact weight. 2,268g on the other hand, is rounded up which is also good in some scenarios, but it's not as accuracte/precise as the exact amount of something.
