<span>Solution 

</span>1 <span>Simplify </span>\frac{225}{23} <span><span>×488</span> to </span>\frac{109800}{23}<span> 
</span>\frac{109800}{23} −236b=<span>4428 
</span>
Subtract \frac{109800}{23} <span> from both sides 
</span>−236b=4428− \frac{109800}{23} 

 <span>Simplify 4428− </span> \frac{109800}{23}<span> to − </span>\frac{7956}{23}
<span>−236b=− </span>\frac{7956}{23}

 <span>Divide both sides by <span>−236
</span></span>b= - \frac{7956}{23} / <span>236

Simplify  </span> \frac{7956}{23} / 236

Simplify \frac{7956}{23}  to  b= \frac{7956}{23} <span>×236 

</span><span>Simplify to </span>\frac{7956}{5428}

Simplify \frac{7956}{5428} to \frac{1989}{1357}

B = \frac{1989}{1357}

Given an arithmetic sequence in the table below, create the explicit formula and list any restrictions to the domain.
djyliett [7]
An=a1+d(n-1)
an=nth term
a1=first term, when n=1
d=common differnce=amount each term increases by
n=which one


so
when n=1, an=40
so a1=40
it seems to increas by 7 each time

an=40+7(n-1)
explicit formula is expanded
an=40+7n-7
an=33+7n is the formula

the domain is natural numbers because you can't have the -3rd term or the 0th term or the 3.24th term

domain is natural numbers
the formula is a_n=33+7n or a_n=7n+33

Write a in slope-intercept form of the line that passes threw (-9,5) and (-3,3)
Amanda [17]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

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

We have the following points:

(x_ {1}, y_ {1}): (- 9,5)\\(x_ {2}, y_ {2}): (- 3,3)

Substituting we have:

m = \frac {3-5} {- 3 - (- 9)}\\m = \frac {-2} {- 3 + 9}\\m = \frac {-2} {6}\\m = - \frac {1} {3}

Thus, the equation is of the form:

y = - \frac {1} {3} x + b

We substitute one of the points and find "b":

3 = - \frac {1} {3} (- 3) + b\\3 = 1 + b\\3-1 = b\\b = 2

Finally, the equation is of the form:

y = - \frac {1} {3} x + 2

Answer:

y = - \frac {1} {3} x + 2

Find the value of X.
Nezavi [6.7K]

Answer:

A. 12

Step-by-step explanation:

TU and CV are two chords of the circle that intersects at point w.

Thus,

x*3 = 9*4 (two intersecting chords theorem)

Solve for x

3x = 36

Divide both sides by 3

\frac{3x}{3} = \frac{36}{3}

x = 12
