Answer:

y = [tex]-\frac{5}{12} x[/tex] Slope is [tex]-\frac{5}{12}[/tex]; y-intercept is [tex]-\frac{11}{12}[/tex].

Step-by-step explanation:

-5x - 12y = 11 Add 5x to each side.

-12y = 5x + 11 Divide each side by -12.

y = [tex]-\frac{5}{12} x + (-\frac{11}{12} )[/tex] Change the + to -.

y = [tex]-\frac{5}{12} x - \frac{11}{12}[/tex]

Slope intercept form is y = mx + b, so slope is [tex]-\frac{5}{12}[/tex]; y-intercept is [tex]-\frac{11}{12}.[/tex]

Answer:

PZ × WP = XP × PY ( substitute values )

14 PZ = 7 × 12

14 PZ = 84 ( divide both sides by 14 )

The directional derivative of [tex]f[/tex] at the given point in the direction indicated is [tex]\frac{5}{2}[/tex].

The directional derivative is represented by the following formula:

[tex]\nabla_{\vec v} f = \nabla f (r_{o}, s_{o})\cdot \vec v[/tex]   (1)

Where:

The gradient of [tex]f[/tex] is calculated below:

[tex]\nabla f (r_{o}, s_{o}) = \left[\begin{array}{cc}\frac{\partial f}{\partial r}(r_{o},s_{o}) \\\frac{\partial f}{\partial s}(r_{o},s_{o}) \end{array}\right][/tex]   (2)

Where [tex]\frac{\partial f}{\partial r}[/tex] and [tex]\frac{\partial f}{\partial s}[/tex] are the partial derivatives with respect to [tex]r[/tex] and [tex]s[/tex], respectively.

If we know that [tex](r_{o}, s_{o}) = (1, 3)[/tex], then the gradient is:

[tex]\nabla f(r_{o}, s_{o}) = \left[\begin{array}{cc}\frac{s}{1+r^{2}\cdot s^{2}} \\\frac{r}{1+r^{2}\cdot s^{2}}\end{array}\right][/tex]

[tex]\nabla f (r_{o}, s_{o}) = \left[\begin{array}{cc}\frac{3}{1+1^{2}\cdot 3^{2}} \\\frac{1}{1+1^{2}\cdot 3^{2}} \end{array}\right][/tex]

[tex]\nabla f (r_{o}, s_{o}) = \left[\begin{array}{cc}\frac{3}{10} \\\frac{1}{10} \end{array}\right][/tex]

If we know that [tex]\vec v = 5\,\hat{i} + 10\,\hat{j}[/tex], then the directional derivative is:

[tex]\nabla_{\vec v} f = \left[\begin{array}{cc}\frac{3}{10} \\\frac{1}{10} \end{array}\right] \cdot \left[\begin{array}{cc}5\\10\end{array}\right][/tex]

[tex]\nabla _{\vec v} f (r_{o}, s_{o}) = \frac{5}{2}[/tex]

The directional derivative of [tex]f[/tex] at the given point in the direction indicated is [tex]\frac{5}{2}[/tex]. [tex]\blacksquare[/tex]

Answer:

x = 54°

Step-by-step explanation:

Since there are 180 degrees in a triangle, all you would do is add up the angles that you already have. In this case, you would do 64 + 62, which is 126. Then you would do 180 minus the sum of the other two degrees to find x. 180 - 126 = 54, so 54 is the value of x.

Hope this helps!!

Answer: Start with the midpoint, G(10,8), and move your pencil point 4 units to the left and  1 unit up to reach the endpoint M(6,9).  To find the other end point, start with the midpoint G(10,8) again, but now move your pencil point 4 units to the right and 1 unit down.  Result:  N(14,7).

Check:  find the mean of the 2 x-coordinates:  Does (6+14)/2 = 10, the x-coordinate of the midpoint?  YES.  Does (9+7)/2 = 8, the y-coord. of the midpoint?  YES.

The desired other end point is therefore N(14,7).

Answer: 45?

Step-by-step explanation: because a perfect corner is 90 degrees so if you split that, you will get 45!

Step-by-step explanation:

Given: Two congruent sides, (DE and EF). Anlge. E is 36.

Let angle F be x°.

According to the base isoceles triangle theroem,

Since Angle F is opposite from DE and Angle D is opposite from EF, and DE=EF.

Angle D = Angle F.

So using transitive property, Angle D is x°. as well.

All angles in triangles add up to 180 so

[tex]36 + x + x + = 180[/tex]

[tex]36 + 2x = 180[/tex]

[tex]2x = 144[/tex]

[tex]x = 72[/tex]

So angle F is 72°.

Since DF is opposite from 36°, the shortest angle, DF is the shortest side.

Answer:

720[tex]\sqrt{5x}[/tex]

Step-by-step explanation:

First you want to simplify both of them. To do this on 4[tex]\sqrt{30^{2} }[/tex] you can just cancel out the square and the square root to get 4 x 30 which is 120. Now you simplify 3[tex]\sqrt{20x}[/tex] you do this by splitting the radical into 2 radicals. So you want to take out a perfect square which in this case is [tex]\sqrt{4}[/tex] and you have [tex]\sqrt{5x}[/tex] left over. This brings us to 120 x 3 x 2 (2 is the square root of 4) [tex]\sqrt{5x}[/tex]. Now multiply 120 x 3 x 2 and get 720[tex]\sqrt{5x}[/tex].

One relation is a linear function

Second one is a graph of non-functional relation

Answer:

below

Step-by-step explanation:

For the first graph, we can use a linear function as it means "straight" lines so when we use the vertical lines test, it passes it (shown below).

We can use a U shaped line so it when we use the vertical line test, it passes through two points to resemble its not a function (shown below).

Answer:

[tex]y = \frac{1}{19} x - \frac{4}{19} [/tex]

Step-by-step explanation:

[tex]x - 19y = 4[/tex]

Slope intercept form :

y= mx+b

Where ;

m = slope

b = intercept

[tex] - 19y = - x + 4[/tex]

Divide through by -19

[tex] \frac{ - 19y}{ - 19} = - \frac{x}{ - 19} + \frac{4}{ - 19} [/tex]

Simplify

[tex]y = \frac{1}{19} x - \frac{4}{19} [/tex]

Answer:

y = (1/19)x - (4/19)

Step-by-step explanation:

x-19y=4

19=m(slope) write it as 1/19

write 4 as 4/19(represents b or y-intercept)

y=mx+b

m=(1/19)

b=(4/19)

Plug in those numbers into the equation to get: y = (1/19)x - (4/19)

I hope that wasn't too confusing. LOL

Answer:

if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.

Step-by-step explanation:

The value of variable x is,

⇒ x = - 3/2

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Two functions are;

⇒ f(x) = (2x+5)/8 and g(x) = 3x - 4.

Here, The inverse of (fog)(x) is an identity function,

Hence, We get;

⇒ (f o g) (x) = f (g (x))

                 = f (3x- 4)

                 = [ 2 (3x - 4) + 5 ] / 8

                 = (6x - 8 + 5) / 8

                 = (6x - 3) / 8

Thus, The inverse of (fog)(x) is,

⇒ (f o g) (x) = (6x - 3) / 8

⇒ y = (6x - 3) / 8

Solve for x;

⇒ 8y = 6x - 3

⇒ 8y + 3 = 6x

⇒ x = (8y + 3) / 6

⇒ (f o g)⁻¹ (x) = (8x + 3) / 6

Here, The inverse of (fog)(x) is an identity function, \

Hence, We get;

⇒ (f o g)⁻¹ (x) = x

⇒ (8x + 3) / 6 = x

⇒ 8x + 3 = 6x

⇒ 8x - 6x = - 3

⇒ 2x = -3

⇒ x = - 3/2

B.

Step-by-step explanation:

to find the midpoint the formula is

[tex]( \frac{x2 + x1}{2} \frac{y2 + y1}{2} )[/tex]

so use the points provided and substitute them in to the formula!!

so now it would look like this inside the formula

and then you'll just solve that !!

[tex]\frac{5 + ( - 4)}{2} = \frac{1}{2} = 0.5[/tex]

so we know x = 0.5 now, solve for y

[tex]\frac{6 + ( - 7)}{2} = \frac{ - 1}{2} = - 0.5[/tex]

and we now know y = -0.5

point form (x,y) and you're all done !!

Belize is more expensive than Brazil. The book costs $6.17 more in Belize. Then the correct option is A.

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

A certain book is for sale in both Belize and Brazil.

In Belize, it sells for 80.39 Belize dollars.

The exchange rate of us dollars to Belize dollars is 1:1.9246

The cost of a book in dollars will be

[tex]\rm \dfrac{C_{belize }}{80.39} = \dfrac{1}{1.9246}\\\\C _{belize } \ = 41.7697[/tex]

In Brazil, it sells for 63.65 Brazilian reals.

The exchange rate of us dollars to Brazilian reals is 1:1.7880.

The cost of a book in dollars will be

[tex]\rm \dfrac{C_{brazil}}{63.65} = \dfrac{1}{1.778}\\\\C _{brazil} \ = 35.5984[/tex]

The difference in the cost will be

[tex]\rm C _{belize} -C _{brazil} = 41.7697 - 35.5984 = 6.1713 \approx 6.17[/tex]

Belize is more expensive than Brazil. The book costs $6.17 more in Belize. Then the correct option is A.
