Answer:

The Simplified equation is 8p - 27

Step-by-step explanation:

1st we can combine like terms which are 4p, 3p , and p

together we get 8p all we haev left is -27 since we can combine it the answer is 8p - 27

If sasha had 85 cookies, and she divided it among 12 people and fraction it in simplest form. What is the answer?

dezoksy [38]

Answer:

Each person gets 7 cookies.

Step-by-step explanation:

Total cookies: 85

Total people will receive cookies: 12

$\frac{85}{12} = 7.08$

If we estimate it to the whole number, that means each person will get 7 cookies.

A student used the slope-intersept form to write the equation of a line that has a slope of -2 and passes through the point (-3/

mina [271]

Answer:

D. Step 6: student needed to add the b value

Explanation:

All the steps are correct and they get the b value of 4.4. Since it's positive, it should be added in the orignal equation. So, it should look like y = -2x + 4.4 instead of y = -2x - 4.4

Find the inverse of f(x) = -4x - 12

olga2289 [7]

Answer:

$\implies f^{-1}(x) =-\dfrac{x}{4}-3$

Step-by-step explanation:

Given :-

f(x) = -4x-12

And we need to find out the Inverse of the function . Let us assume that f(x) = y . Now , firstly replace x with y and vice versa.

Function :-

$\implies f(x) = -4x - 12 \\\\\implies y = -4x-12$

Interchanging x and y :-

$\implies x = -4y - 12$

Solve out for y :-

$\implies x = -4y - 12 \\\\\implies -4y = x +12 \\\\\implies y =\dfrac{x+12}{-4}\\\\\implies y =-\dfrac{x}{4}-3$

Replace y with f-¹(x) :-

$\implies f^{-1}(x) =-\dfrac{x}{4}-3$

Hence the inverse of the function is -x/4-3 .

Please help me, I don't understand literally any of this. # 1-6

1. y = x
y = 2x - 4

Locate the point of intersection of the 2 graphs. This is the solution set of the graphs, that is: (x, y) = (4, 4).

Solution set: (x, y) = (4, 4)

2. y = - $\frac{1}{2}$ x + 5
y = 3x - 2

Locate the point of intersection of the 2 graphs. This is the solution set of the graphs, that is: (x, y) = (2, 4)

Solution set: (x, y) = (2, 4)

3. y - 2x = 4
y = 2x

Locate the point of intersection of the 2 graphs. The 2 lines are parallel so they do not intersect and therefore no solution set exists for the given set of equations.

Solution set: Does not exist.

4. y - 4x = 8
y = 2(2x +4)

Locate the point of intersection of the 2 graphs. The 2 lines are completely overlapping each other so they intersect intersect at infinite points and therefore infinite solutions exist for the given set of equations.

Solution set: Infinite solutions

5. x + y = 3
y = -3(2x - 1)

Locate the point of intersection of the 2 graphs. This is the solution set of the graphs, that is: (x, y) = (0, 3)

Solution set: (x, y) = (0, 3)

6. -x + y = -2
y = 2

Locate the point of intersection of the 2 graphs. This is the solution set of the graphs, that is: (x, y) = (4, 2)

Solution set: (x, y) = (4, 2)
