3x = 24 You are not supposed to subtract 3 from x, you are supposed to divide instead. So you will divide each side by 3. 

So it would be:
x = 8

I think its line 5 cuz they subtracted 3 but I think your supposed to divide.

shusha [124]
<span>(14+x)^2= 25^2 +x^2
14^2 + 28x + x^2 = </span><span>25^2 +x^2
28x = 25^2 - 14^2
28x = 625  - 196
28x = 429

Please help me, I have no idea what the equation for the new path is. <br><br> Thank you!!
Citrus2011 [14]
First, find the slope of the initial line; 

m=(y₁-y₂)/(x₁-x₂) 

m=(4-0)/(11-8) 
m=4/3 

If two lines are parallel, the slope is the same although the intercept can differ. 

If this parallel lines passes through the point (4, 5); 

y=(4/3)x+c <-- plug in coordinates to solve for c
5=(4/3)(4)+c 
(15/3)=16/3+c 
(15/3)-(16/3)=c 
-1/3=c 

Therefore, the final equation should be y=4/3x-1/3

Hope I Helped :)

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per da
andriy [413]

Answer:

4.1975\cdot 10^{7}

Step-by-step explanation:

We are told that the average human heart beats 1.15\cdot 10^{5} times per day and there are 3.65\cdot 10^{2} days in one year.

To find number of heart beats in one year we will multiply number of heart beats in one day by number of days in one year.

1.15\cdot 10^{5}\times 3.65\cdot 10^{2}

Now we will solve this problem using exponent properties.

1.15 \times 3.65\cdot 10^{2+5}

1.15 \times 3.65\cdot 10^{7}

4.1975\cdot 10^{7}

Our answer is in scientific notation we can represent it in standard form as 4.1975\cdot 10^{7}=4.1975*10000000=41975000 times.

Therefore, average human heart beats in one year 4.1975\cdot 10^{7} or 41975000 times.
