What is the equation of the line passing through the points (-3,7) and (3,3)

Sav [38]

$\text{Given that,}\\\\(x_1,y_1) = (-3,7)~~ \text{and}~~(x_2,y_2) =(3,3)\\\\\\\text{Slope, }~~ m =\dfrac{y_2-y_1}{x_2 - x_1}= \dfrac{3-7}{3-(-3)} = -\dfrac{4}{3+3} = -\dfrac 46 = -\dfrac 23\\\\\\\text{Equation with given points ,}\\\\y- y_1 = m(x-x_1)\\\\\implies y -7 = -\dfrac 23 (x +3)\\\\\implies y -7= -\dfrac 23 x - 2\\\\\implies y = -\dfrac 23 x -2 +7 \\\\\implies y = -\dfrac 23 x +5\\\\\implies 3y = -2x +15 \\\\\implies 2x +3y = 15$

Which set of ordered pairs is a partial solution set for the system y<0 and x≤y?

jeka57 [31]

Answer:

{(−1,−1),(−7,−6),(−8,−2),(−10,−3)}

Step-by-step explanation:

we are given

y<0 and x≤y

so, we can write as

$x\leq y$

so, both values must be less than 0 or negative

we will verify each options

option-A:

Since, $x\leq y$

So, all solution satisfies

so, this is TRUE

option-B:

Since, $x\leq y$

x=-6 and y=-7

-7<-6

so, y<x

So, it does not satisfy solution

so, this is FALSE

option-C:

Since, solutions will be in points

intersection means interval

so, this is not valid solution

so, this is FALSE

option-D:

Since, $x\leq y$

So, all solution satisfies

so, this is TRUE

NEED TO KNOW ASAP<br> Which of the following is a quadratic inequality?<br> Oy<2x+7<br> Oy Oy

Burka [1]

Answer:

Step-by-step explanation:

A quadratic inequality is one that involves a quadratic polynomial.

<h3>Identification</h3>

The degree of a polynomial is the value of the largest exponent of the variable. When the degree of a polynomial is 2, we call it a <em>quadratic</em>.

For the following inequalities, the degree of the polynomial in x is shown:

y < 2x +7 . . . degree 1
y < x^3 +x^2 . . . degree 3
y < x^2 -5x . . . degree 2 (quadratic)

<h3>Application</h3>

We see that the degree of the polynomial in x is 2 in ...

y < x^2 -5x

so that is the quadratic inequality you're looking for.

<em>Additional comment</em>

When a term involves only one variable, its degree is the exponent of that variable: 5x^3 has degree 3. When a term involves more than one variable, the degree of the term is the sum of the exponents of the variables: 8x^4y3 has degree 4+3=7.
