halla los valores de "x y "y" en cada caso, y todos los ángulos de las figuras​

Answer:

A and C

Step-by-step explanation:

alternate-exterior angles need to have one angle above the first line and the other angle below the second line and the angles have to be on different sides of the transversal

Answer:

v=-12

Step-by-step explanation:

-8=v+4

-4     -4

-12=v

Answer:

v = -12

Step-by-step explanation:

We have the equation v + 4 = -8

Subtract 4 from both sides.

v + 4 - 4 = -8 - 4

+4 and -4 cancel one another out.

We get v = -12.

I would appreciate brainliest but if not that's ok!

Answer:

arc 1 = 100 degrees

angle 2 = 50 degrees

Step-by-step explanation:

arc 1 = 2(50)   (arc = 2 x inscribed angle)

arc 1 = 100 degrees

angle 2  = 1/2 arc 1 = 50 degrees

Answer: 14500

Step-by-step explanation:

Let the price of the mobile phone before the GST was added be represented by x.

Therefore,

x + (12% × x) = 16240

x + 0.12x = 16240

1.12x = 16240

x = 16240/1.12

x = 14500

The price of the mobile phone before the GST was added was 14500

[tex]\boxed {\boxed {\sf 2 \ real \ solutions }}[/tex]

Step-by-step explanation:

The quadratic formula is:

[tex]{x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex]

The discriminant of a quadratic is just the expression under the square root, or [tex]b^2-4ac[/tex]. This can tell us the number of solutions a quadratic has.

If the discriminant is:

Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

Answer:

75

Step-by-step explanation:

they gave u 105 it is parallel to the line above it so u add them

105+105=210

then u subtract with 360 which forms a full angle

then u get 150

now u got the total of 2 angles so u divide them with2 to get 1 angle

then the answer is going to be 75

Answer:

66 students

Step-by-step explanation:

To find how many played bass instruments, multiply 120 by 0.55

120(0.55)

= 66

So, 66 students played bass instruments

Answer:

we need to diagram to answer this question for you, can you show us a picture of the diagram please?

Answer:

For the inequality to be true, both factors must have the same sign or one factor must be 0. The zeroes occur at x = − 2 , x = 5 . Thus, our intervals will be ( − ∞ , − 2 ] , [ − 2 , 5 ] , [ 5 , ∞ ) Take a sample point from each. A sample point of − 3 for the first interval yields ( − 3 + 2 ) ( − 3 − 5 ) = ( − 1 ) ( − 8 ) = 8 , so the first interval satisfies the inequality. Choosing a sample point of x = 0 for the second interval, we receive ( 2 ) ( − 5 ) = − 10 , so this interval will not satisfy the equality. A sample point of x = 6 for the third interval gives us ( 8 ) ( 1 ) = 8 , so the third interval satisfies. Thus, the domain that satisfies the inequality is ( ∞ , − 2 ] & [ 5 , ∞ ) On the number line , you would draw and fill in a circle above -2, and draw an arrow from that point to the left. You would then draw and fill in a circle above 5, and provide a similar arrow to the right (i.e. towards positive infinity). We fill in these circles because the intervals are closed at these points, i.e. these points satisfy the inequality. If we instead had ( x + 2 ) ( x − 5 ) > 0 , the circles would be empty because those points would not satisfy.

Answer:

Step-by-step explanation:

Let 'x' be the original price.

x + 39% of x = 197.38

x + 0.39 x   = 197.38

1.39x  = 197.38

      x = 197.38/ 1.39

      x = 142

197.38-76.98=120.40

Answer:

put angel sum property on it

Step-by-step explanation:

39 + 73 + x = 180

112 + x = 180

x = 180 - 112

x = 68

put degree sign over it

7.69+2.75+1.25=11.69

Answer: y = (1/3)*x - 7

Step-by-step explanation:

When we have a line:

y = a*x + b

A perpendicular line to this one needs to have a slope s equal to:

s = -(1/a)

Then any line written as:

y = -(1/a)*x + c

is perpendicular to the lines of the form "y = a*x + b"

Then if we have the line:

y = -3*x - 8

The family of perpendicular lines to this one is:

y = -(1/-3)*x + c

y = (1/3)*x + c

where c can be any real number.

Now we also want that this line passes through the point (9, -4)

Then we need to replace x by 9, and y by -4

-4 = (1/3)*9 + c

Now we can solve this for c.

-4 = 9/3 + c

-4 = 3 + c

-4 - 3 = c

-7 = c

Then the line that is perpendicular to the line y = -3x – 8 and that goes through (9, -4) is:

y = (1/3)*x - 7
