Y=f(x)
basically solve for y
mnus 9x both sides
3y=12-9x
divide both sides by 3
y=4-3x
f(x)=4-3x

Paula has her own business making cakes for
djverab [1.8K]

Answer:

Since Paula has her own business of making cakes for special occasions, and the total price (P) of one of Paula's cakes is represented by the equation P = 0.75S +10, where S is the number of people the cake serves, for determine what does the 0.75 represent in this situation and what does the 10 represent in this equation, the following mathematical reasoning must be carried out:

P is the price of the cake

S is the number of servings

Therefore, 0.75 is the value of each serving, which can be variable (the number of servings can vary)

In turn, 10 is the fixed cost of each cake.

Put the following equation of a line into slope intercept form, simplifying all fractions. 8x+10y=-30
Mama L [17]

The slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.

<h3>What is the slope-intercept form of the given equation?</h3>

The slope-intercept form is expressed as;

y = mx + b

Where m is the slope and b is the y-intercept.

Given the equation in the question;

8x + 10y = -30

To convert to slope intercept form, we make y the subject of the formula and simplify.

8x + 10y = -30

10y = -8x - 30

Divide each term by 10

10y/10 = -8x/10 - 30/10

y = -4x/5 - 3

y = (-4/5)x - 3

Therefore, the slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.
