$\huge \rm༆ Answer ༄$

First Consider two points ~ (0 , -3) and (-1 , 0)

Now, use the given formula to calculate slope :

$\sf \dfrac{y2 - y1}{x2 - x1}$

$\sf \dfrac{0 - ( - 3)}{ - 1 - 0}$

$\sf \dfrac{ 0 + 3 }{ - 1}$

$\sf \dfrac{3}{ - 1}$

$\sf - 3$

Therefore, the slope of the graph is -3

The length of a rectangle is three more than twice the width. Determine the dimensions that give a total area of 27ft squareda.

Nuetrik [128]

Area = 27ft^2

length = l

width = w

Equation

l = 2w + 3

Section A

Area

A = l*w

A = (2w + 3)* w or A = 2w^2 + 3w

27 = 2w^2 + 3w

2w^2 + 3w - 27 = 0 This is the equation

Section B

2w^2 - 6w + 9w - 27 = 0

2w(w - 3) + 9(w - 3) = 0

(w - 3)(2w + 9) = 0

w1 - 3 = 0 2w + 9 = 0

Hello please help i’ll give brainliest if you give a correct answer

vodomira [7]

Answer:

D. The equator would become warmer, while the poles become colder

Step-by-step explanation:

So the reason in this is actually due to the fact that the ocean currents bring heat from the equator. A study was actually done a bit ago that stated that “Europe would drop 5 to 10 degrees Celcius.“

Also this is more of a science question in my opinion LOL.

Which are the solutions of the quadratic equation x^2=-5x-3

frutty [35]

The correct answer would be $\frac{-5 +/- \sqrt{13} }{2}$

In order to solve for this you must first get the equation equal to 0.

<span>x^2=-5x-3 ----> add 5x to both sides.
x^2 + 5x = -3 ----> add 3 to both sides.
x^2 + 5x + 3 = 0

Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.

a = 1 (because it is the coefficient to x^2)
b = 5</span> (because it is the coefficient to x)
c = 3 (because it is the end number)

Now we can plug these values into the quadratic equation.

$\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}$

$\frac{-5 +/- \sqrt{5^{2} - 4(3)(1) } }{2(1)}$

$\frac{-5 +/- \sqrt{13} }{2}$

And those would be your two answers.
