Since bx does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting bx from both sides.
<span>-ay=-bx+2 </span>
<span>ax+by=3 </span>
<span>Divide each term in the equation by -1a. </span>
<span>y=(bx-2)/(a) </span>
<span>ax+by=3 </span>
<span>Divide each term in the numerator by the denominator. </span>
<span>y=(bx)/(a)-(2)/(a) </span>
<span>ax+by=3 </span>
<span>The equation is not linear, so the slope does not exist. </span>
<span>No slope can be found. </span>
<span>ax+by=3 </span>
<span>Since ax does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting ax from both sides. </span>
<span>No slope can be found. </span>
<span>by=-ax+3 </span>
<span>Remove the common factors that were cancelled out. </span>
<span>No slope can be found. </span>
<span>y=-(ax)/(b)+(3)/(b) </span>
<span>Divide each term in the equation by b. </span>
<span>No slope can be found. </span>
<span>y=(-ax+3)/(b) </span>
<span>Divide each term in the numerator by the denominator. </span>
<span>No slope can be found. </span>

<span>No slope can be found. </span>
<span>Compare the slopes (m) of the two equations. </span>
<span>m1=, m2= </span>
<span>The equations are parallel because the slopes of the two lines are equal.

This is known as "5 take 3", where ordering is not important.

Answer:
x=31
Step-by-step explanation:
-3x-3(19)=3-5x+2
2x-57=5
2x=62
x=31
We are given with
n = 1000
p = 0.78
Samples = 10
Condition = at most 7 have one or two social media accounts
We can use combinations to solve the problem
P = ∑10Ci (0.78)^i (1-0.78)^(10-i)/ 1000C10 from i from 0 to 7
Solve for P
Alternate exterior means opposite sides of the transversal and outside the parallel lines... angles 1, 2, 5, 6 are all outside the parallel lines.. now you just need to match up the ones that are on opposite sides... 1 and 5 are opposite sides and 2 and 6 are opposite sides.. so those two pairs are the alternate exterior angles.. since 2 and 6 isn't a choice and 1 and 5 is, then there is your answer.
