The equation should be y = 3x + 7
Answer:
The answer is -4 1/26
Step-by-step explanation:
-35/4 ÷ 13/6
= -35/4 × 6/13
= -35/2 × 3/13
= -105/26
= -4 1/26

You can plan retirement now to know what you will do later on and plan on how much money you will collect
Answer:
1) 11
2) 4
Step-by-step explanation:
1) It is 11 because in the first row we ignore the 0 since it is referring to the first digit, so the first row has 7. In the second row, we ignore the one so it would be 4 because the 9, or would be 19, is above 18.
2) It is 4 because there is one person over 65. In the second row we ignore the 7 and there are 3 people in the 7 row.
In case you're not already aware, the expression
is called the "difference quotient" and represents the average rate of change of a function
over an interval
.
For the function
, by substituting
we get
![f(x+h)=(x+h)^2+3(x+h)+4=(x^2+2xh+h^2)+(3x+3h)+4=x^2+3x+4+(2x+3)h+h^2](https://tex.z-dn.net/?f=f%28x%2Bh%29%3D%28x%2Bh%29%5E2%2B3%28x%2Bh%29%2B4%3D%28x%5E2%2B2xh%2Bh%5E2%29%2B%283x%2B3h%29%2B4%3Dx%5E2%2B3x%2B4%2B%282x%2B3%29h%2Bh%5E2)
Then the difference quotient is
![\dfrac{f(x+h)-f(x)}h=\dfrac{(x^2+3x+4+(2x+3)h+h^2)-(x^2+3x+4)}h](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%28x%2Bh%29-f%28x%29%7Dh%3D%5Cdfrac%7B%28x%5E2%2B3x%2B4%2B%282x%2B3%29h%2Bh%5E2%29-%28x%5E2%2B3x%2B4%29%7Dh)
![=\dfrac{(2x+3)h+h^2}h=2x+3+h](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%282x%2B3%29h%2Bh%5E2%7Dh%3D2x%2B3%2Bh)
where the last equality holds as long as
.
