Which is the equation of the line that passes through the point (2, -2) and has a slope of 3? A. y = 3x - 2 B. y = 3x - 8 C. y = 2x + 3 D. y = - 2x + 2​

Answers

Answer 1

Answer:

y = m x + b      standard equation for straight line

-2 = 3 *2 + b    to satisfy above equation

b = -8

therefore

y = 3 x - 8

if x = 2 then y = -2

A class has 9 boys and 18 girls. The class as a whole has a GPA (grade point average of 2.96, and the boys have a GPA of 2.40. What is the GPA of the girls? (Round your answer to two
decimal places

Answers

9514 1404 393

Answer:

  3.24

Step-by-step explanation:

The weighted average GPA is ...

  (9(2.40) +18g)/(9+18) = 2.96

Then the girls' GPA (g) is ...

  ((27)(2.96)-9(2.40))/18 = g = 58.32/18 = 3.24

The GPA of the girls in the class is 3.24.

_____

Additional comment

The solution expression can be rearranged to ...

  ((9+18)(2.96) -(9)(2.40))/18 = g

  2.96 +(9/18)(2.96 -2.40) = g

  2.96 +(1/2)(0.56) = g

That is, the difference of the boys' GPA from the overall average, multiplied by the ratio of boys to girls, is the amount that must be added to the overall average to get the girls' GPA. This is arithmetic you can do in your head.

The key idea with the average is that the sum of differences from the average is zero. If 9 boys each have a GPA 0.56 units below the average, then twice as many girls will each have a GPA that is half as much above the average.

Find the value for a for which 3y - ax = 8 and 4x + 8y = 2 are perpendicular.

Answers

Step-by-step explanation:

3y+8y=11y and -ax+4x=4ax

Answer:

a = 6

Step-by-step explanation:

Perpendicular lines have slope that are negative reciprocal of each other. There product = -1

Solve both equations for y.

3y - ax = 8                                 4x + 8y = 2

3y = ax + 8                                  8y = -4x + 2

y = ax/3 + 8/3                               y = -4x/8 + 2/8

 y = a/3(x) + 8/3                              y = -1/2(x) + 1/4

Now you know that the slope of  y = -1/2(x)+ 1/4  is -1/2

and the slope of y = a/3(x) + 8/3 is a/3.  

Looking for the value of "a" that will make the lines perpendicular.

You know that one line slope is -1/2 so the other line slope is 2 because the slope are negative reciprocal.   Also remember that the slope is the coefficient of the x term.

Now   a/3 = 2 ; a = 6

What is the midpoint of AB?

Answers

Answer:

[tex](-4, -\frac{1}{2})[/tex]

Step-by-step explanation:

Hi there!

We are given the line segment, with the end points AB

The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).

We want to find the midpoint of the line segment AB

The midpoint formula is given as [tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are coordinates

We have two coordinates, which is what we need, but let's label their values to avoid any confusion:

[tex]x_1=-5\\y_1=-4\\x_2=-3\\y_2=3[/tex]

Now substitute those values into the formula:

[tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex]

[tex](\frac{-5+ -3}{2}, \frac{-4+ 3}{2})[/tex]

Now simplify the numerator and denominator

[tex](\frac{-8}{2}, \frac{-1}{2})[/tex]

Simplify again:

The midpoint is (-4, [tex]-\frac{1}{2}[/tex])

Given f (x) = x2 + 6x + 5 and g(x) = x3 + x2 − 4x − 4, find the domain of f over g of x period

{x ∈ ℝ}
{x ∈ ℝ| x ≠ −5}
{x ∈ ℝ| x ≠ −1, −2, 2}
{x ∈ ℝ| x ≠ −2, 2}

Answers

The main limiting issue with the domain this function is potentially picking an x-value that makes that denominator equal 0, because dividing by 0 is bad.

So, the domain will be all real numbers, except for those that make g(x)=0.

g(-1) = 0, g(-2)=0, and g(2) = 0, so -1, -2, and 2 must be excluded from the domain.

Your answer is {x ∈ ℝ| x ≠ −1, −2, 2}.

Answer:

[tex]\textsf{Domain}: \quad \{ x \in \mathbb{R}\;|\;x \neq -1, -2, 2\}[/tex]

Step-by-step explanation:

Given functions:

[tex]\begin{cases} f(x)=x^2+6x+5\\g(x)=x^3+x^2-4x-4\end{cases}[/tex]

Factor function f(x):

[tex]\begin{aligned}\implies f(x)&= x^2+6x+5\\&=x^2+x+5x+5\\&=x(x+1)+5(x+1)\\&=(x+5)(x+1)\end{aligned}[/tex]

Factor function g(x):

[tex]\begin{aligned}\implies g(x)&=x^3+x^2-4x-4\\&=(x+1)(x^2-4)\\&=(x+1)(x+2)(x-2)\end{aligned}[/tex]

Therefore the composite function is:

[tex]\implies \dfrac{f(x)}{g(x)}=\dfrac{(x+5)(x+1)}{(x+1)(x+2)(x-2)}[/tex]

A rational function is undefined when the denominator equals zero.

Therefore, the given composite function is undefined when (x+1)(x+2)(x-2)=0:

[tex]x+1=0 \implies x=-1[/tex][tex]x+2=0 \implies x=-2[/tex][tex]x-2=0 \implies x=2[/tex]

The domain of a function is the set of all possible input values (x-values).

Therefore, as the composite function is undefined when x = -1, x = -2 and x = 2, the domain is:

[tex]\{ x \in \mathbb{R}\;|\;x \neq -1, -2, 2\}[/tex]
