Hey! Hope that I can help.
To do this, you need to multiply the 540 by 12.5 and also
to get your answer.
Answer: 16.88
I think that Devon swam at least 35 minutes each day for 5 days because if he exercised 225 minutes and each day he walked for 10 minutes then if you divide 225 by 5 you get 45 so every day he exercised 45 minutes and since he walked for 10 minutes you subtract 10 from 45 which gives you 35 so he swam for 35 minutes.
Answer: Hope this helps you
1/2
Step-by-step explanation:
<em>To find the x-int of any equation, you will need to replace the y with a 0 since when the x-int is when y is 0.</em>
8x+2y = 4 ➨ 8x+2*0 = 4
<em>Now I will do 2*0 which anything times 0 is equal to 0. And we are left with the equation of:</em>
8x = 4
<em>Now I will divide both sides by 8, which isolates our x.</em>
x = 1/2
The x-int is 1/2.
Y = 3x - 4.....the slope here is 3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, u flip the slope and change the sign. So we will need a slope of -1/3...see how I flipped the slope of 3/1 and made it 1/3...and then changed the sign, making it -1/3.
y = mx + b
slope(m) = -1/3
(2,1)...x = 2 and y = 1
now we sub and find b, the y int
1 = -1/3(2) + b
1 = -2/3 + b
1 + 2/3 = b
3/3 + 2/3 = b
5/3 = b
so ur perpendicular equation is : y = -1/3x + 5/3
Answer:
f'(x) = -f(x) = 9xy² - 6x²y + 5x³
Step-by-step explanation:
f(x) = –9xy² + 6x²y – 5x³
additive inverse: f'(x) = -f(x) = 9xy² - 6x²y + 5x³
f(x) + f'(x) = f(x) -f(x) = (–9xy² + 6x²y – 5x³) + (9xy² - 6x²y + 5x³) = 0
