evaluate: 5/6 + 4/9 =___?​

Answer:

I believe it should be (-7,-2)

Step-by-step explanation:

Hi there!

We are given two exterior angles. Don't panic! We know that exterior angles form a linear pair, which means they add up to 180 degrees.

180-130=50

180-96=84

Now that we have those angles, how can we work out the value of x?

Turns out that all the angles in any triangle add up to 180 degrees.

So

180-84-50=46 degrees.

So the value of x is 46 degrees.

Now let's work out the value of x in the next problem.

180-126=54

180-54-43=83 degrees

So the value of x in this problem is 83 degrees.

Let's move on to the third problem.

At first, it seems like we do not have enough information.

If we know that the right angle is 90 degrees (it is shown by a little square), then we have enough information.

180-90-43=47 degrees

So the value of x is 47 degrees.

Hope this helps you!

Answer:  [I assume:  "4x 3y = 7" is really 4x + 3y = 7]

y = -(4/3)x -14/3

Step-by-step explanation:

Rewrite this as y=mx+b, where m is the slope.  

4x + 3y = 7

3y = -4x +7

y = -(4/3)x +(7/3)

The slope is -(4/3)

A parallel line will have the same slope, but a specific value of b to allow it to go through the given point (-5,2):

y = -(4/3)x + b

Enter the point and solve for b:

2 = -(4/3)(-5) + b

2 = (20/3) + b

b = 2 - (20/3)

b = 6/3 - 20/3

b = -14/3

y = -(4/3)x -14/3

[tex]\frac{4-(-1)}{3-(-2)}[/tex] =[tex]\frac{5}{5}[/tex]= 1

Answer:

Step-by-step explanation:

m = -1 ;  ( 4 , -3)

y - y1 = m(x - x1)

y - (-3) = -1(x - 4)

y+ 3 = -x + 4

Add  x to both side.

x +y + 3 = 0

Subtract 4 from both sides

    x + y  + 3 - 4 = 0

x +y - 1 = 0

Answer:

[tex]\sf f^{-1}(x) = \dfrac{x}{2}+4[/tex]

Step-by-step explanation:

A function is given to us and we need to find the inverse of the function in slope intercept form . The given function is ,

[tex]\sf\implies f(x) = 2x - 8 [/tex]

Let us assume that y = f(x) , so that ,

[tex]\sf\implies y = 2x - 8 [/tex]

Now interchange the positions of x and y , we have ,

[tex]\sf \implies x = 2y - 8[/tex]

Solve for y in terms of x ,

[tex]\sf \implies 2y = x + 8 \\\\\sf\implies y =\dfrac{x}{2}+4 [/tex]

This is the inverse of the function in slope intercept form. Now we can replace this y with f-¹(x) , as ,

[tex]\sf \implies \boxed{\pink{\frak{f^{-1}(x) = \dfrac{x}{2}+4}}}[/tex]

Answer:

105 miles

Step-by-step explanation:

The ratio you have is 1:15

So you must multiply 7 by 15 to find the actual distance in miles.

Answer:

3rd option

Step-by-step explanation:

3(x + 8) - 9x = 6(4 - x) ← distribute parenthesis on both sides

3x + 24 - 9x = 24 - 6x , collect like terms on left side )

24 - 6x = 24 - 6x

Since both sides are the same then any value of x will make the equation true.

That is all real numbers are solutions

Answer:

x = 15

Step-by-step explanation:

Here's an easy way to solve this:

OAP appears to be a right isosceles triangle. Angle O is a right angle, so the other angles are congruent (the same).

180-90 = 90

90÷2 = 45

3x = 45

x = 15

Answer:

It is Linear Increasing.

Step-by-step explanation:

If it is a straight line, it is a linear function. if it is NOT a straight line, then it is a non-linear function.

Edit: When the line starts from the top of the y-axis, then it is decreasing. If the line starts from the Origin Point (as shown in the picture you included), then it is increasing. I hope this helps you in Linear and Non-linear relationships.

Answer:

5x - y = 21  

Step-by-step explanation:

Given the linear equation in point-slope form, y + 6 = 5(x - 3):

In order to transform the given equation into its standard form, Ax + By = C, start by distributing 5 into the parenthesis:

y + 6 = 5(x - 3)

y + 6 = 5x - 15

Subtract 5x from both sides:

- 5x + y + 6 = 5x - 5x - 15

- 5x + y + 6 = - 15

Subtract 6 from both sides:

- 5x + y + 6  - 6 = - 15 - 6

- 5x + y = - 21

Divide both sides by -1:

[tex]\frac{-5x + y}{-1} = \frac{-21}{-1}[/tex]

5x - y = 21

Answer:

10

Step-by-step explanation:

Parentheses first so

7-10=-3

then the brackets

-2-3-15=-20

-4-20=-24

so thats the numerator

the denominator is

2(-1)=-2

-20/-2= ?

We can remove the negative because two negatives make a positive then we would divide by 2

20/2=10

Answer:

Step-by-step explanation:

Verify the graphs by the vertical line test.

If a vertical line crosses the graph at two or more points, then it is not a function.

We can see the first 3 graphs pass the test but the last one fails.

So the last graph (bottom right picture)  doesn't represent a function.
