Answer:

a = r + d - c

Step-by-step explanation:

a + c = r + d

You want a alone on the left side. c is being added to a.

To get rid of the c, you must subtract c from the left side, but the rule of equations is that you must do the same operation to both sides of the equation. We subtract c from both sides of the equation.

a + c - c = r + d - c

c - c = 0, so the c is eliminated from the left side.

We now have

a + 0 = r + d - c

a = r + d - c

If the speed of a car is 20 m s^-1 then what is its speed in km h^-1 ?<br>#no spam

ivanzaharov [21]

Speed in m/s=20m/s

We have to convert it to km/h

$\\ \sf\longmapsto 20\times \dfrac{3600}{1000}$

$\\ \sf\longmapsto 20\times \dfrac{18}{5}$

$\\ \sf\longmapsto 4times 18$

$\\ \sf\longmapsto 72km/h$

First .... the limit of the given function is NOT EQUAL to 5 (it diverges so it has no limit). There is a typo. The 14 should be positive.

$\lim_{x \to\ 7} \bigg(\dfrac{x^2-9x+14}{x-7}\bigg)=5$

The precise definition of a limit is:

$\text{If for every } \epsilon>0\text{ there exists a }\delta >0\text{ such that}\\|f(x)-L|$

Given:

$f(x) = \dfrac{x^2-9x+14}{x-7}\\\\L=5\\\\a=7\\\\\\|f(x)-L|$

⇒ $\epsilon = \delta$

When ε = 0.1, δ = 0.1

When ε = 0.01, δ = 0.01
