write the equation in slope-intercept form with y intercept of −3 and an x intercept of −4.5. Plz tell me how you got it so i no

erastovalidia [21]

The equation of the line is y = -2/3x - 3.

To find this, we first need to turn the intercepts into ordered pairs.

x intercept: (-4.5, 0)

y intercept: (0, -3)

Now we can use these two points and the slope equation to find slope.

m = (y2 - y1)/(x2 - x1)

m = (0 - -3)/(-4.5 - 0)

m = 3/-4.5

m = -2/3

Now that we have the slope, we can use slope intercept form to find the intercept.

y = mx + b

-3 = 2/3(0) + b

-3 = 0 + b

-3 = b

Which allows us to model the equation as y = -2/3x - 3

Which expressions are equivalent to the one below? Check all that apply.

V125BC [204]

Answer:

Step-by-step explanation:

The given expression is $10x$ .

We have to check which of he given options on simplification gives the same given expression.

(A) The expression is:

= $\frac{50x}{5x}$

= $10$

which is not equivalent to the given expression, thus this option is incorrect.

(B) The expression is:

= $10(10x)-1$

= $100x-1$

which is not equivalent to the given expression, thus this option is incorrect.

(C) The expression is:

= $10(10x)+1$

= $100x+1$

which is not equivalent to the given expression, thus this option is incorrect.

(D) The expression is:

= $\frac{50x}{5}$

= $10x$

which is equivalent to the given expression, thus this option is correct.

(E) The expression is:

= $(\frac{50}{5})x$

== $10x$

which is equivalent to the given expression, thus this option is correct.

(F) The expression is:

= $x^5$

which is not equivalent to the given expression, thus this option is incorrect.

an Olympic swimming pool is 6 meters long how many lives will and have to swim in order to swim 1 kilometer

vlada-n [284]

I'm guessing you mean laps here
Let's find out how many meters are in a kilometer. Kilo is 1000 more than a single unit, so for every kilometer you have 1000 meters.

so divide 1000/6 to find the amount of laps to swim 1 kilometer
