Step-by-step explanation:

Answer:  (y-9) = -4(x-1)

Step-by-step explanation: The format of a point-slope line is y − y1 = m(x − x1), where x1 and y1 are a known point on a line with slope m.  Given slope of -4 and a point of (1,9):

(y − y1) = m(x − x1)

(y − 9) = -4(x − 1)

This can be rearranged to the standard form:  y = -4x+13

Answer:

52%

Step-by-step explanation:

you got to divide 15 by 785. First 15 goes into 78 5 times which is 75. Then subtract 78 by 75 which is 3. Then bring down the 5 which makes 35 and then 15 goes into 35 two times which is 30 subtract 35 by 30 which is 5 bring up the 5 into a fraction and the ansewer in percentage is  52%.

Answer:

-1  3/ 4

Step-by-step explanation:

The percentage of the cub scout which are atleast as old as the near scout refers to percentage of the cub scout which are atleast 8 years old. Hence, the percentage is 28%

Cub scouts which are atleast 8 years old :

Hence, the percentage of cub scout which are atleast 8 years old is 28%

Therefore, the percentage of the cub scout that are atleast as old as the Bear scout is 28%

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides )

Here n = 5 , then

sum = 180° × 3 = 540°

Sum the given angles and equate to 540

2b - 90 + 90 + b + 45 + b + [tex]\frac{3}{2}[/tex] b = 540, collect like terms

4b + 1.5b  + 45 = 540 ( subtract 45 from both sides )

5.5b = 495 ( divide both sides by 5.5 )

b = 90

then

2b - 90 = 2(90) - 90 = 180 - 90 = 90

b + 45 = 90 + 45 = 135

[tex]\frac{3}{2}[/tex] b = 1.5b = 1.5 × 90 = 135

The angles from least to greatest are

90° , 90° , 90° , 135° and 135°

Answer:

45 Miles

Step-by-step explanation:

45 + 45 = 90

90 + 45 = 135

Answer:

You work for x hours and earn $20 for each hour. You get paid $60 before you come in each day. What is y when you work for x hours?

Step-by-step explanation:

x is the independent variable and can vary. You have to add the $60 in there, too. Adding them together gets you to y = 20x + 60 and this real life scenario works.

Answer:

Sum is 14

Step-by-step explanation:

The value of the 10th term of the geometric progression is 30517.578

Based on the information given,

First term = 8

Second term = 20

Common ratio = 20/8 = 2.5

The nth term of a geometric progression is calculated as:

= ar[tex]n[/tex] - 1

The 10th term will then be:

= 8 × (2.5)[tex]9[/tex]

= 8 × 3814.6973

= 30517.578

Therefore, the value of the 10th term of the geometric progression is 30517.578.

The 10th term of the geometric sequence is: 30,715.578.

In a geometric sequence, the quotient between consecutive terms is always the same, called common ratio q.

The equation for the nth term is:

[tex]a_n = a_1q^{n-1}[/tex]

In this problem:

[tex]q = \frac{50}{20} = \frac{20}{8} = 2.5[/tex]

Thus, the nth term is given by the following equation:

[tex]a_n = 8(2.5)^{n-1}[/tex]

The 10th term is:

[tex]a_{10} = 8(2.5)^9 = 30517.578[/tex]

The 10th term of the sequence is 30,715.578.

Answer:

[tex]x=5/2[/tex]

Step-by-step explanation:

When [tex]f(x)=30[/tex], we have [tex]3x+9x=30[/tex].

Combining like terms on the right side, we have [tex]12x=30[/tex].

Finally, dividing by [tex]12[/tex] we get [tex]x=30/12[/tex].

We note that [tex]30=6*5[/tex] and [tex]12=6*2[/tex], so [tex]30/12=5/2[/tex].

So, [tex]\boxed{x=5/2}[/tex] and we're done!

x = 72

y = 54

z = 54

================================================================

The regular pentagon has all five sides the same length. It also has all interior angles the same measure. This leads to y = z. These two angles are the congruent base angles of the isosceles triangle. The base angles are opposite the congruent sides.

The fact that we have a regular pentagon also means that the five triangles shown are identical copies of one another (i.e. they are congruent triangles). Divide the full 360 degree rotation into 5 parts to get 360/5 = 72, which represents the measure of the central angle x.

--------------

For any triangle, the three angles always add to 180. This means,

x+y+z = 180

72+y+z = 180 .... plug in x = 72

72+y+y = 180 ... recall that y = z

2y+72 = 180

2y = 180-72

2y = 108

y = 108/2

y = 54, which is also the measure of angle z as well

--------------

As a quick check,

x+y+z = 72+54+54 = 180

which helps confirm the answer.

Answer:

80

Step-by-step explanation:

in the figure above, angle 100 degrees is corresponding to the angle co - interior to angle x

that is

if we put an angle that is at the upper left of x, we can call that y which is corresponding to 100 degrees

since y is corresponding to 100 degrees, it automatically becomes the same as 100 degrees

therefore y=100

now, from the first line above, we know that x and y are co-interior which means that they both add up to 180 degrees

that is

x+y=180

we know that y = 100

therefore,

x+100=180

collect like terms and

x = 180-100

therefore,

x= 80
