Answers

Answer:

I apologize if this was poorly explained. The explanation for each is below the angle.

Since these triangles are in a rectangle, The top and bottom triangles are congruent, and the left and right triangles are congruent. All 4 triangles are also Isosceles. (Two equal sides/angles)

m<1= 59

(Left and right triangles are congruent)

m<2=31

(Top and bottom triangles are congruent)

m<3= 59

(Directly across from the other 59)

m<4=31

(Each of the rectangles corner angles totals to 90 degrees, therefore making this angle 31 degrees.)

m<5=31

(Since the triangles are isosceles, this angle is also 31)

m<6= 59

(Since m<5 is 31, this angle is 59.)

m<7=118

{(Two other angles in the triangle) 31+31= 62 180-62= 118)}

m<8=62

{(Two other angles in the triangle)59+59= 118. 180-118= 62}

m<9=62

(This angle and m<8 are congruent.)

m<10=118

(This angle and m<7 are congruent.)

m<11=31

(Same reason as m<4)

Answers

Answer:

y = - 2x + 9

Step-by-step explanation:

From y = -2x + 1

comparing with y = mx + c

slope (m) = - 2

Writing in point slope form

y - y1 = m(x - x1)

y - 1 = -2( x - 4)

y - 1 = -2x + 8

Now writing in slope intercept form

y = - 2x + 8 + 1

y = -2x + 9

Tabitha has 5 music files, each with 9 songs in it. She is dividing the songs into 7 groups. If each of group will have the same number of songs, how many songs will be left over?

Answers

Answer:

The amount of songs that will be left over is 3.

Step-by-step explanation:

First, you have to multiply the number of music files for the number of songs in each file to find the total amount of songs that Tabitha has:

5 music files*9 song in each file= 45 songs

Now, that you know that she has 45 songs and as you know that she is dividing them in 7 groups that will have the same number of songs, you have to divide the number of songs by the number of groups:

45/7=6.42

So, this means that she will have 7 groups with 6 songs in each one which would be equal to 42 songs as 7*6=42. Finally, to find the amount of songs that will be left over, you have to subtract 42 songs from the total amount of songs that Tabitha has:

45-42=3

According to this, the answer is that the amount of songs that will be left over is 3.

How many root(s) does the following equation have? Explain how you know for credit.
-6x2 - 6x + 7 = 7

Answers

Answer:

This equation has two roots.  We know this because of the format it is in.  Any expression in the form ax² + bx + c is a quadratic one, which describes a parabola and has two roots.

In this case, the roots are -1 and 0.

Step-by-step explanation:

Let's see if we can find those values:

-6x² - 6x + 7 = 7

-6x² - 6x = 0

x² + x  = 0

x(x + 1) = 0

x = -1, 0

We could also run through solving this by completing the square:

-6x² - 6x + 7 = 7

-6x² - 6x = 0

x² + x  = 0

x² + x + 0.25 = 0.25

(x + .5)² = 0.25

x + .5 = ±√0.25

x + .5 = ± 0.5

x = -0.5 ± 0.5

x  = -1, 0
