Answer:

y=-\frac{2}{3}x +300

Step-by-step explanation:

y=mx+b

we have two points

point A=(0,300)

point B=(450,0)

slope=m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{0-300}{450-0}

m=-2/3

we need to find "b"

using point A=(0,300), we have

300=0+b

b=300

finally we have

y=-\frac{2}{3}x +300

NEED QUICKLY <br> GEOMETRY 20 POINTS
sp2606 [1]

Answer:

10.24 in²

Step-by-step explanation:

First we need to know how to find the area of a rectangle, which is base * height.

We can notice that the base and height are both 3.2, so we multiply 3.2*3.2.

To do this, we first have to completely ignore the decimal points. Just pretend you're multiplying 32*32, to get 1024. Then, we count how many numbers are past the decimal point on each number. On both, there is 1 number past, and we add those together to get 2 numbers past the decimal point.

We then, finally, make the number we got (1024) have 2 numbers past the decimal point, so instead of 1024, we have 10.24, which is our answer!

For which function is the average rate of change over the interval 1 &lt; x &lt; 5 greater than the average rate of change over
Rainbow [258]

Answer:

We do not have the function g(x), but this can be solved in a trivial way.

The average rate of change in a interval is the slope over that interval, so the average rate of change of g(x) in the interval 1 < x < 5 is

p = (g(x2) - g(x1))/(x2 - x1) where x2 > x1

p = (g(5) - g(1))/(5 - 1) = (g(5) - g(1))/4

Now, suppose that i have the new equation h(x) = g(x) + x

the rate of change of this function, the average rate of change in the interval will be:

p' = (h(5) - h(1))/(5 - 1) = (g(5) + 5 - g(1) - 1)/4 = (g(5) - g(1))/4 + 4/4 = p +1

so p' > p

and the average rate of change of h(x) is bigger than the one of g(x) in the interval 1< x < 5
