i am thinking of 2 numbers when i add my numbers the answer is 1 when i multiply my numbers the answer is 0.09 what is the numbe
Virty [35]
X + y = 1.....x = 1 - y
x * y = 0.09

y(1 - y) = 0.09
y - y^2 = 0.09....re-arrange
y^2 - y + 0.09 = 0
(y - 0.9)(y - 0.1) = 0

y - 0.9 = 0      x + y = 1
y = 0.9           x + 0.9 = 1
                      x = 0.1

y - 0.1            x + y = 1
y = 0.1           x + 0.1 = 1
                      x = 0.9

so ur 2 numbers are : 0.1 and 0.9

I need help i am very confused
sasho [114]

9+12=m or 9+12=21

this is because when we start with m-9=12 we know that m is supposed to be the sum of 9 and 12.

if we check our work we will see this

9+12=21

9+12=21

m-9=12

21-9=12

Find the average rate of change of f(x)=2x-1 from x=-1 to x=2
MrMuchimi

The average rate of change from x = -1 to x = 2 is 2

<u>Solution:</u>

Given function is:

f(x) = 2x - 1

We have to find the average rate of change from x = -1 to x = 2

<em><u>The average rate of change is given as:</u></em>

\text {Average rate of change}=\frac{f(b)-f(a)}{b-a}

<em><u>The average rate of change from x = -1 to x = 2 is given by formula:</u></em>

\text {Average rate of change}=\frac{f(2)-f(-1)}{2-(-1)}\\\\\text {Average rate of change}=\frac{f(2)-f(-1)}{3}

<em><u>Find f(2) and f( - 1)</u></em>

<em><u>Substitute x = 2 in given function</u></em>

f(2) = 2(2) - 1 = 4 - 1 = 3

<em><u>Substitute x = -1 in given function</u></em>

f( - 1) = 2(-1) - 1 = -2 - 1 = -3

<em><u>Substitute the values in above formula,</u></em>

\text {Average rate of change}=\frac{3-(-3)}{3}=\frac{6}{3}=2

Thus average rate of change from x = -1 to x = 2 is 2
