What is the answer for x

alexandr402 [8]

Answer:

x = 8.5

Step-by-step explanation:

I got this answer by assuming the triangles were congurent, if they are not, the answer may vary.

first, make an equation:

x + 8 = 3x - 9

bring 3x to the other side, by subtracting it

-2x + 8 = -9

Subtract 8

-2x = -17

divide by -2

x = 8.5

Then, just sub x into the formulas

2 2/3 of what number is 6 1/7

borishaifa [10]

$2\frac{2}{3}$ of $2\frac{17}{56}$ is $6\frac{1}{7}$

Solution:

Given $2\frac{2}{3}$ of what number is $6\frac{1}{7}$ .

Let us first convert the mixed fraction into improper fraction.

$$2\frac{2}{3}=\frac{(2\times3)+2}{3}=\frac{8}{3}$

$$6\frac{1}{7}=\frac{(6\times7)+1}{3}=\frac{43}{3}$

Now, let us take the unknown number be x.

$$2\frac{2}{3}\times x=6\frac{1}{7}$

$$\frac{8}{3}\times x=\frac{43}{7}$

Do the cross multiplication.

$$ x=\frac{43}{7}\times\frac{3}{8}$

$$ x=\frac{43\times3}{7\times8}$

$$ x=\frac{129}{56}$

Now, again change the improper fraction into mixed fraction.

$$ x=2\frac{17}{56}$

Hence $2\frac{2}{3}$ of $2\frac{17}{56}$ is $6\frac{1}{7}$ .

Use the following graph of the function f(x) = −3x4 − x3 + 3x2 + x + 3 to answer this question: What is the average rate of chan

Alinara [238K]

the average rate of change is just the slope from (0,f(0)) to (1,f(1))

find f(0) and f(1)

$f(0)=-3(0)^4-(0)^3+3(0)^2+0+3=3$

$f(1)=-3(1)^4-(1)^3+3(1)^2+1+3=-3-1+3+1+3=3$

slope from (0,3) to (1,3) is rise/run=(3-3)/(0-1)=0/-1

the average rate of change from x=0 to x=1 for f(x) is 0

Take some time to fill in your notes, the area that is not shown in this video. Fill in the table with the values you think are

joja [24]

The x-values are the heartbeat(s) and the y-values are the time(s)

<h3>How to determine the x and y values?</h3>

The variables are given as:

Time(s) and Heartbeat(s)

As a general rule, the action that is being done is the independent variable.

The action here is the heartbeat.

So, the x-values are the heartbeat(s) and the y-values are the time(s)

A possible value of this is;

x = 100, y = 60 seconds

So, the ordered pair is (100,60)

When represented as ratio, we have;

Ratio = 60/100

Simplify

Ratio = 0.6 heartbeat per second
