Solve the following equation for x: 5x + 3y = 15.

zepelin [54]

Answer:

B) x = (-3/5)y + 3

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

first, subtract 3y from btoh sides:

5x + 3y (-3y) = 15 (-3y)

5x = -3y + 15

Next, divide 5 from both sides:

(5x)/5 = (-3y +15)/5

x = (-3/5)y + 3

B) x = (-3/5)y + 3 is your answer.

(SELECT ALL THAT APPLY)

steposvetlana [31]

The sequences of transformations that could be applied to the parent function will be:

reflect over the y-axis, vertically stretch by a factor of 3, and then shift down 1 unit
shift right 1 unit, reflect over the y-axis, and then vertically stretch by a factor of 3.
reflect over the x-axis, vertically stretch by a factor of 3, and then shift down 1 unit.

<h3>What is transformation?</h3>

A transformation of a function is a function that turns one function or graph into another, usually related function or graph.

In this case, the sequences of transformations could be applied to the parent function f(x) = x to obtain the graph of g.
