Answer:
63
Step-by-step explanation:
-1,5,15,29,41,63
between the 2nd term and first term, we add 6
between the 3rd and 2nd, we add 10
between 4th and 3rd, we add 14
between 5th and 4th, we add 12
to get the next term, we add 22 to the fifth tern which is 63
this is how to get the 4th term 6 interval was added to 8 making 14 and to get the fifth, then add 2 to the difference of 10 making 12. 29+12=41..so to get the last term 14 was added to 8 making 22 and therefore 41+22=63
∠A and \angle B∠B are vertical angles. If m\angle A=(3x-30)^{\circ}∠A=(3x−30)
∘
and m\angle B=(2x-9)^{\circ}∠B=(2x−9)
∘
, then find the value of x.
Answer:
[tex]x=21\textdegree[/tex]
Step-by-step explanation:
So we know that:
[tex]\angle A=3x-30 \text{ and}\\\angle B=2x-9[/tex]
And that the two angles are vertical angles.
Since they are vertical angles, their measurements are equivalent. Thus, to find x, set the equations equal to each other:
[tex]\angle A=\angle B\\(3x-30)=(2x-9)[/tex]
Now, solve for x. Add 30 to both sides. The left side cancels:
[tex](3x-30)+30=(2x-9)+30\\3x=2x+21[/tex]
Now, subtract 2x from both sides. The right cancels:
[tex](3x)-2x=(2x+21)-2x\\x=21[/tex]
Thus, the value of x is 21.
Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. Radius r Arc Length s 19 feet 7 feet
Answer:
The radian measure of the central angle of the given circle is [tex]\frac{7}{19} rad[/tex]
Step-by-step explanation:
The radian measure of the central angle θ of a circle of radius r that intercepts an arc of length s can be calculated from the formula given below
s =rθ
where s is the length of arc
r is radius of the circle
and θ is the central angle in rad (radian)
From s = rθ, Then
θ = s / r
From the question,
Radius r = 19 feet
and Arc length s = 7 feet
Hence,
θ = s / r becomes
θ = 7 / 19
∴ θ [tex]= \frac{7}{19} rad[/tex]
This means the radian measure of the central angle of the given circle is [tex]\frac{7}{19} rad[/tex]

Draw the graphs of 2x+y=6 and 2x-y +2=0.shade the region bounded by these 2 lines and x-axis
Answer: see graph
Step-by-step explanation:
Rewrite each equation in y = mx + b. Then plot the y-intercept (b) and count rise over run (m) to plot the next point. Draw a line through the points.
2x + y = 6 --> y = -2x + 6 --> m = -2, b = 6
2x - y + 2= 0 --> y = -2x +2 --> m = -2, b = 2
Shade the area between the intersection of those two lines and the x-axis.

given m||n find the value of x
Answer: x= 17°
Step-by-step explanation:
The two measures have to add up to 180 degrees.
(7x -1) + (5x -23) = 180 combine like terms on the left side
12x - 24 = 180 add 24 to both sides

-3(8n - 5) - 2n = 8n - 21
Answer:
Step-by-step explanation:
First you do the parentheses so the -3 x 8n= -24 and -3 x -5= 15
so it will look like this. -24n+15-2n=8n-21
Now combine like terms the -24n-2n.
-26n+15=8n-21 now subtract 8n now it will look like this
-34n+15=-21 now -15 from -21
-34n=-36
now if you want n by its self divide -34 and -36

All of the x values or inputs are called what?
Answer:
its called a Domain
Step-by-step explanation:
All of the x-values or inputs are called Domain.
"x-values" is the word used in mathematics and statistics to describe the input values or independent variables in a function or equation.
These x-values stand for a function's inputs, arguments, or the points at which a mathematical connection is being assessed.
The outputs or dependent variables of a function are represented by the appropriate y-values, which are often paired with the associated x-values. The link between the independent and dependent variables can be seen on a graph by plotting the x-values and y-values together as data points.
For example, in the equation y = 2x + 3, "x" represents the x-values or inputs, while "y" represents the corresponding y-values or outputs. By substituting different values for x, you can calculate the corresponding y-values and observe how changes in the x-values affect the relationship described by the equation.
Hence the answer is Domain.

An office supply company ordered 24 cartons of specialty paper. The regular price for a carton of specialty paper is $6.88. They received a discount of $1.75 off each carton. About how much money will the office supply company need to pay for the paper? Which of the expressions gives a reasonable estimate of the answer?
Answer:
$123.12Step-by-step explanation:
Given that the regular price for the specialty paper is
$6.88 per carton
and the company receives a discount of $1.75 per carton
this means that the company will pay $6.88-$1.75 = $5.13 per carton
To calculate the cost of the supply for 24 cartons we have
24*5.13= $123.12
the cost of the supply is $123.12
alternatively we can also calculate the percentage discount as
Actual cost of 24 cartons= 24*6.88= $165.12
Discount= $6.88-$1.75 = $5.13 per carton
%discount= 1.75/6.88= 0.2543
= 25.43%
The price after discount is
=$165.12*(1-0.2543)
=$165.12*0.7456
= $123.12

Step-by-step explanation:
Consider the following.
Answer:
(-8, 7); x + y = 13 → y= -x + 13
parallel lines have the same slope. slope is -1
y = -x + b
7 = -(-8) + b
7 = 8 + b
b = -1
(a) y = -x - 1
perpendicular lines have opposite slopes. slope is 1/2.
y = -1/2x + b
7 = -1/2(-8) + b
7 = 4 + b
b = 3
(b) y = -1/2x + 3
Use the number line below, where RS = 9y +5, ST = 5y + 6, and RT = 123.
a. What is the value of y?
b. Find RS and ST.
Answer:
[tex]y=8[/tex]
RS: 77
ST: 46
Step-by-step explanation:
We know that RS and ST together make the line RT. This means the sum of their lengths will be equal to RT.
Since RT is 123, we can create the equation [tex]9y+5+5y+6=123[/tex].
Combining like terms gets us [tex]14y+11=123[/tex]
We can now solve for y by isolating the variable on one side of the equation.
[tex]14y + 11 - 11 = 123-11\\\\14y=112\\\\14y\div14 = 112\div14\\\\y=8[/tex]
Now we know the value of y. We can now substitute this into the expressions for RS and ST to find their values.
RS = [tex]9y+5\\\\(9\cdot8)+5\\\\72+5\\\\77[/tex]
ST = [tex]5y+6\\\\(5\cdot8)+6\\\\40+6\\\\46[/tex]
We can confirm this is correct because [tex]46+77=123[/tex].
Hope this helped!
