Answer:
if that is supposed be a decimal then round tenths place which is still six
Step-by-step explanation:
Manny can assemble a computer in 50 minutes. That means, in a minute Manny does
![\frac{1}{50}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B50%7D)
job.
Lucy can assemble a computer in 45 minutes. That means, in a minute Lucy does
![\frac{1}{45}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B45%7D)
job.
If they are working together, in a minute they will do:
![\dfrac{1}{50} + \dfrac{1}{45}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B1%7D%7B50%7D%20%2B%20%5Cdfrac%7B1%7D%7B45%7D%20)
![= \dfrac{9}{450} + \dfrac{10}{450} \text{(equalize the denominator)}](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B9%7D%7B450%7D%20%2B%20%5Cdfrac%7B10%7D%7B450%7D%20%5Ctext%7B%28equalize%20the%20denominator%29%7D)
![=\dfrac{19}{450}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B19%7D%7B450%7D%20)
In a minute they will do
![\frac{19}{450}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B450%7D%20)
job
To finish the job they will do it in
minutes or about 24 minutes.
The two points are (x, f(x)) and (x+h, f(x+h)). To find the slope, the definition is the change in y over the change of x. Does this sound familiar!! Applying this definition we get the following formula: and the points x<span>1 = 2 and x2 = 4. Then in our general answer, we will replace x with x1 and h = x2 - x1. Replacing these values in the formula yields 2(2) + (4 - 2) = 4 + 2 = 6. Thus, the slope of the secant line connecting the two points of the function is 6. </span><span>Now using the same function as above, find the average rate of change between x1 = -1 and x2<span> = -3. The answer is 2(-1) + ( -3 + 1) = -2 + -2 = -4. This means that the secant line is going downhill or decreasing as you look at it from le</span></span>
Answer:
(hope this helps can I pls have brainlist (crown) ☺️)
Step-by-step explanation:
7^8 x 7^3 x 7^4 / 7^9 7^5
= 7^(8+3+4) / 7^(9+5)
= 7^15 / 7^14
= 7^(15-14)
= 7.
When the bases of the numbers are the same when multiplying numbers with exponents, you can just add the exponents like so:
7^8 x 7^3 x 7^4= 7^15
Now, look at the rest of the simplified equation and do the same to the denominator:
7^15 / 7^9 x 7^5 ⇒ 7^15/ 7^14
When the bases are the same in the fraction, you are allowed to subtract the exponents. This will lead you to the simplified answer = 7^15-14 = 7^1 = 7
