Answer:
x=3, y= - 2
Step-by-step explanation:

Which expression is equivalent to (-5/6) / (10/3)?
Answer:
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}[/tex]
Let us solve the expression
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=\frac{-\frac{5}{6}}{\frac{10}{3}}[/tex]
Apply fraction rule: [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]=-\frac{\frac{5}{6}}{\frac{10}{3}}[/tex]
Divide fractions: [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]
[tex]=-\frac{5\cdot \:3}{6\cdot \:10}[/tex]
Multiply the numbers: [tex]6\cdot \:10=60[/tex]
[tex]=-\frac{5\cdot \:3}{60}[/tex]
Multiply the numbers: [tex]5\cdot \:3=15[/tex]
[tex]=-\frac{15}{60}[/tex]
Cancel the common factor: 15
[tex]=-\frac{1}{4}[/tex]
Therefore, we conclude that the equivalent expression is:
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]

Answer:
We conclude that:
f(g(3)) = 2
Hence, option B is correct.
Step-by-step explanation:
Given the f(x) table
x 2 3 4 5
f(x) 0 1 2 3
Given the g(x) table
x 1 2 3 4
g(x) 1 2 4 8
We need to determine f(g(3)).
In order to determine f(g(3)), first, we need to determine g(3)
It is clear from the table of g(x),
at x = 3, g(3) = 4
so
f(g(3)) = f(4)
Now, we need to check the value of f(4) at x = 4 using the table f(x)
It is clear from the table of f(x),
at x = 4, f(4) = 2
Thus,
f(g(3)) = f(4) = 2
Therefore, we conclude that:
f(g(3)) = 2
Hence, option B is correct.

Graph the line that has a slope of −13 and contains the point (3,−7)
Graph the line that has a slope of −13 and contains the point (3,−7) intercept is 32.
straight line graph can be represented two form
cartesian form ax+ by +c=0
slope intercept form y=mx +c
Where m is slope and c is the intercept in y axis
Value of m = change in y/change in x
back to question :- slope is -13
So, [y2-y1]/[x2-x1]= -13
{y+7/x-3 } = -13
y+7 = -13x +39
for intercept just put x=0
so y = 39-7
y=32
y= -13x +32
slope = -13
intercept = 32
Graph the line that has a slope of -1/3 and contains the point (3-7)
Plot the point (3,-7)
slope = -1/3 means y decreases 1/3 when x increases by 1
Let x increase by 3, then y decreases by 3(1/3) = 1
Put your pencil at (3,-7)
Increase x by 3 to (6,-7)
Decrease y by 1 to (6,-8)
Plot the point (6,-8)
Draw the graph as a line thru (3,-7),(6,-8)

James paid an initial fee of $6.00 for a movie rental service. Each time he rents a movie he is charged $2.00. Sarah uses a different movie
rental service that charges based on the equation y = 3x + 4, where y is the total cost and x is the number of movies rented. At what point
are the prices of the two services the same?
606
Answer:
We have system of equations
James's total cost: Y = 2x + 6 (1)
Sarah's total cost: Y = 3x + 4 (2)
replace y = 2x + 6 and (2) => 2x + 6 = 3x + 4 => x = 2 => y = 10
So the total cost of renting movies by James And Sarah is equal
