Answer:
(-36 x^3)/25
Step-by-step explanation:
Simplify the following:
(-4×9 x^2 x)/(5×5)
Combine powers. (9 x (-4) x^2)/(5×5) = (9 x^(2 + 1) 4 (-1))/(5×5):
-(9×4 x^(2 + 1))/(5×5)
2 + 1 = 3:
((-9×4 x^3)/5)/5
9 (-4) = -36:
(-36 x^3)/(5×5)
5×5 = 25:
Answer: (-36 x^3)/25
Answer:
step 1 is the answer
if you like my answer please like comment and mark me as brilliant
Both <em>Px</em> + <em>Qy</em> = <em>R</em> and <em>Tx</em> + <em>Uy</em> = <em>V</em> have the same solution (2, 9), meaning the point (2, 9) lies on both lines such that <em>x</em> = 2 and <em>y</em> = 9 makes both equations true.
When you add these equations together, you get
(<em>Px</em> + <em>Qy</em>) + (<em>Tx</em> + <em>Uy</em>) = <em>R</em> + <em>V</em>
→ (<em>P</em> + <em>T</em> ) <em>x</em> + (<em>Q</em> + <em>U</em> ) <em>y</em> = <em>R</em> + <em>V</em>
so the first option is equivalent.
When you subtract the first equation from the second, you get
(<em>Tx</em> + <em>Uy</em>) - (<em>Px</em> + <em>Qy</em>) = <em>V</em> - <em>R</em>
→ (<em>T</em> - <em>P</em>) <em>x</em> + (<em>U</em> - <em>Q</em>) <em>y</em> = <em>V</em> - <em>R</em>
so the third option is also equivalent.
The answer to the first one would be B. The formula for exponential decay with the filled in values are as follows: 25000(.85)^5 Just plug it into a calculator.
The answer to the second question would also be B. The easiest way to get this answer is to find the slope, or how much the y is changing per change of one in x. In this case you can subtract to find it increases by 3 each time. Subtract three from the y value at one to get the y value at 0 or the y intercept
