Okay so you want to find out how many days would be needed to get 32 million new accounts.
First take 32÷0.4=80
Then your going to take 0.4×80=32
Answer: (this is solving for m)
m= −4
/7
n + −8
/7
Step-by-step explanation:
7m + 4n + 8+ −4n =0 + −4n
7m + 8= −4n
7m + 8 + −8 = −4n + −8
7m = −4n − 8
7m
/7 = (−4n − 8 )
/7
m= −4
/7
n + −8
/7
Answer:
(2x - 3)⁵= 32x⁵ - 240x⁴ + 720x³ - 1080x² + 810x - 243
Step-by-step explanation:
We need to write the expansion of Binomial (2x - 3)⁵
Here general form of binomial expansion is:
(a + b)ⁿ = ⁿC₀aⁿ + ⁿC₁aⁿ⁻¹b + ⁿC₂aⁿ⁻²b² + ⁿC₃aⁿ⁻³b³ + ... + ⁿCₙbⁿ
(2x - 3)⁵= ⁵C₀(2x)⁵ + ⁵C₁(2x)⁵⁻¹(-3) + ⁵C₂(2x)⁵⁻²(-3)² + ⁵C₃(2x)⁵⁻³(-3)³
+⁵C₄(2x)⁵⁻⁴(-3)⁴ + ⁵C₅(2x)⁵⁻⁵(-3)⁵
(2x - 3)⁵= (32x⁵) + 5(16x⁴)(-3) + 10(8x³)(-3)² + 10(4x²)(- 3)³ + 5(2x)(-3)⁴+(-3)⁵
(2x - 3)⁵= 32x⁵ - 240x⁴ + 720x³ - 1080x² + 810x - 243
That's the final answer.
Domain is another word for the x value. so, this question just asking us to solve for y when x = 7
first, substitute in x
y = 3(7) -4
and then solve for y
y = 21 - 4
y = 17
so, the range is 17 when the domain is 7
