Answer:

x 2 + 5 x + 6

Step-by-step explanation:

y = m x + c

y- intercept

x = 0

y = (-2) (0) + 3

(x =0, y = 3)

<h3>slope -2 </h3><h3>y = -1 x + 3</h3>

Which ordered pair is a solution to the system of equations?

enot [183]

Answer:

See below

Step-by-step explanation:

Given system:

2x - y = - 2
15x - 2y = - 7

Solve by elimination, multiply the first equation by - 2 and add up the equations:

-2(2x - y) + 15x - 2y = - 2(- 2) - 7
-4x + 2y + 15x - 2y = 4 - 7
11x = - 3
x = - 3/11

Find the value of y:

2( - 3/11) - y = - 2
-6/11 - y = - 2
y = 2 - 6/11
y = 1/11

Solution is:

( - 3/11, 1/11)

None of the answer choices is matching this solution. Something must be wrong with the given equations.

blondinia [14]

Answer:

Part A:

P(x)=15x^4+30x^3-50

Part B:

P(4)=$4270

Step-by-step explanation:

Part A:

In order to find the profit function P(x) we have to integrate the P'(x)

P'(x)=x(60x^2+90x)

P'(x)=60x^3+90x^2

$\int\limits {p'(x)} \, dx =\int\limits {60x^3+90x^2} \, dx$

P(x)=15x^4+30x^3+C

when x=0, C=-50

P(x)=15x^4+30x^3-50

Part B:

x=4

P(x)=15x^4+30x^3-50

P(4)=15*4^4+30*4^3-50

P(4)=$4270

Profit from selling 400 pounds is $4270
