Answer:

Angle BAC is 5 degrees.

Step-by-step explanation:

It's easiest if you just annotate you diagram as you find each angle. You can do this in lots of different ways, but this is how i got there.

So to find BAC, you need to find ABC and BCA. After you find these two, its just a matter of subtraction, which is simple.

We already know ABC = 55 degrees.

So now we have to find BCA:

1) They told us that BCD is 60 degrees and that its sitting on a straight line

2) From this we can find that BCA is 120 degrees, because a straight line is 180 degrees. 180 -60 = 120 degrees.

Now that we have both ABC and BCA, we can find BAC:

1) The angles of all triangles add up to 180 (idk why, its just how it is)

2) So, if we do 180 - BCA - ABC, we should get BAC

3) So, 180 - 55 - 120 = 5 degrees

Sorry if the explanation was really long, its a bit weird to explain it all in words. Hope it helped : )

Answer:

one real solution

Step-by-step explanation:

the equation simplified is (x+4)²

Option 3 (two real solutions) is the right answer.

A quadratic equation in the variable x is an polynomial of degree 2 equation of the form ax²+bx+c = 0 where a, b, c are real numbers a≠0. For example, 2x²-3x+1 =0. And we say that x=α is an solution of a quadratic equation if α satisfies the equation and since its degree is two it will always have 2 solutions which may be real or Imaginary.

Given equation here is : x² -8x+16= 0

                                       x²-2.4x+4²=0

                                      (x-4)²=0

                                     x=4,4

Hence, the quadratic equation has two equal and real solutions.

Answer:

  A 2-column table has 3 rows. The first column is labeled x with entries 40, 160, 200. The second column is labeled y with entries 60, 15, 0.

Step-by-step explanation:

All of the tables have x=40 in the first column. The function value there is ...

  f(x) = (-3/8)(40) +75 = -15 +75 = 60

Only the last table has y = 60 for x = 40.

A check of the other points in that table shows they are all on the same (second) piece of the graph, as required by the problem statement. Those points are marked with a purple x in the attachment.

Inverse of -5-9x/x-6

Step-by-step explanation:

Steps:

1: Interchange the variables x and y.      

x=6y-5/y+9

2: Solve x = 6y-5/y+9 for y

3: Multiply both sides by y+9

4: Simplify and Expand

5: Subtract 9x from both sides.

6: Simplify and Subtract y from both sides then Simplify again

7: Divide both sides by x-6

Answer: Inverse of -5-9x/x-6

Hope this helps.

Answer:

To find the inverse, interchange the variables and solve for

Answer:

[tex](-1,5)[/tex]

Step-by-step explanation:

The definition of the diameter indicates it passes through the center of the circle to be called diameter. Therefore finding the midpoint of the line that is the diameter we will find the center of the circle.

To find the coordinates of this midpoint we must make an average of the 'x' values of the two given points, and also an average of the two given 'y' values.

the coordines of this midpoint will be [tex](x_{m},y_{m})[/tex] where [tex]x_{m}[/tex] is the average of the 'x' values, and [tex]y_{m}[/tex] is the average of the 'y' values

The points we have are:

[tex](3,7)[/tex]

where I will call the coordinates: [tex]x_{1}=3[/tex] and [tex]y_{1}=7[/tex]

[tex](-5,3)[/tex]

where I will call the coordinates: [tex]x_{2}=-5[/tex] and [tex]y_{2}=3[/tex]

the average of the 'x' values is:

[tex]x_{m}=\frac{x_{1}+x_{2}}{2}[/tex]

substituting the values:

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

the average of the 'y' values is:

[tex]y_{m}=\frac{y_{1}+y_{2}}{2}\\[/tex]

substituting the values:

[tex]y_{m}=\frac{7+3}{2}\\ \\y_{m}=\frac{10}{2}\\ \\y_{m}=5[/tex]

and the center of the circle (the midpoint of the diameter) is at:

[tex](x_{m},y_{m})[/tex]

which is

[tex](-1,5)[/tex]

Answer:

Step 3

Step-by-step explanation:

She made her first mistake in Step 3.

This is because 4/7 is actually less than 5/3.

Step 1 and 2 are mathematically accurate.

1/2 is less than 1.

So, since 4/7 is only greater than 1/2 and not greater than 1 as compared to 5/3 which is actually greater than 1, she should have concluded that 4/7 is less than 5/3.

Therefore, Step 3 contains the mistake.

Answer:

y=ax2+bx+c

Step-by-step explanation:

In this equation, the vertex of the parabola is the point (h,k) . You can see how this relates to the standard equation by multiplying it out: y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k .

Answer:

A line parallel to the y-axis has no defined slope, and a line parallel to the x-axis has slope of zero.

Step-by-step explanation:

Lines parallel to the y-axis are vertical and are undefined as they don't technically have a gradient.

lines parallel to the x-axis are horizontal and have a gradient of 0 since there is no positive or negative angle, it's just straight.
