The eighth term of an arithmetic sequence is double the value of the third term. The fifth term is equal to 14. Determine the first term and the common difference of the sequence.
Answer: first term = 6
Common difference = 2
Step-by-step explanation:
Eight term =a +(n-1)d = a +(8-1)d = a + 7d
Third term = a+(n-1)d = a + (3-1)d =a + 2d
a + 7d = 2(a + 2d)
a + 7d = 2a + 4d
7d - 4d = 2a - a
a = 3d
The fifth term is equal to 14. This is:
a + 4d = 14
Put the value of a into the equation here
3d + 4d = 14
7d = 14
d = 14/7
d = 2
Recall that a + 4d = 14
a + 4(2) = 14
a + 8 = 14
a = 14 - 8
a = 6

Which of the following is equivalent to 4x - 3y = 12 ?
y = -4/3x - 4
y = 4/3x + 4
y = -4/3x + 4

Answer:
y = 4/3 x - 4
Step-by-step explanation:
The slope-intercept form of the equation of a line
The equation of a line can be expressed in several forms. One of them is the slope-intercept form:
y = mx + b
Where
m = slope
b = y-intercept
We are required to convert the equation of the line:
4x - 3y = 12
It can be done by solving for y.
Subtracting 4x:
- 3y = - 4x + 12
Dividing by -3;
y = 4/3 x - 4

Answer:
A
Step-by-step explanation:
A is the only option that equals 48 besides 4x12, which is not really prime factorization.
Also, 48 breaks down into 16x3, which breaks down into either [tex]2^{4}[/tex] or [tex]4^{2}[/tex] x 3, since 3 is already a prime number.
How do you write the equation in slope intercept form given (2,2) and (0,-2)?
Answer:
y = 2x - 2
Step-by-step explanation:
The slope-intercept form of the equation of a line is
y = mx + b
where m is the slope, and b is the y-intercept.
y = mx + b
First we find the slope, m.
slope = (difference in y)/(difference in x)
It does not make a difference which point is first and which point is second in finding the differences, but you must do the x- and y-differences in the same order.
slope = (-2 - 2)/(0 - 2) = -4/(-2) = 2
The slope is 2, so m = 2, and now we have:
y = 2x + b
We need to find the value of b, the y-intercept.
We use one of the given points. Let's use (2, 2). We plug in 2 for x and 2 for y and solve for b.
2 = 2(2) + b
2 = 4 + b
-2 = b
b = -2
Now that we know the y-intercept is -2, we substitute b with -2.
y = 2x + b
y = 2x - 2
Answer: y = 2x - 2

What percent of the surface area of the ottoman is green not including the bottom .The radius of the ottoman is 22 in and the cushion is 6 in and the green is 10 in
Answer:
37%
Step-by-step explanation:
Surface area of a cylinder = πr² + 2πrh
With r = 22 and h = (6 + 10) = 16
Area = π * 22² + 2 * π * 22 * 16
Area = 1520.728 + 2211.968
Area = 3732.696 in²
Percentage of green = surface area of green ÷ total surface area
Surface area of green = 2πrh
Surface area of green = 2 * π * 22 * 10
Surface area of green = 1382.48
Percentage of green = 1382.48 / 3732.696 * 100%
Percentage of green = 37%

find 2 numbers whose sum is 36 and diffrence is 10
Answer:
23 and 13
Step-by-step explanation:
can you help me with my latest answer too??i'm on a time limit rn
Answer:
13 and 23Step-by-step explanation:
let 2 number be x and y
x + y = 36 ---- equation ( 1 )
x - y = 10 -----equation ( 2 )
from ( 1 ) and ( 2 )
2y = 26
y = 13
putting value of Y in equation ( 1 )
x + y = 36
x + 13 = 36
x = 36 - 13
x = 23

the diagram shows a triangle drawn between a pair of parallel lines
Find value of x and y
Answer:
x = 60
y = 80
Step-by-step explanation:
x° + 120° = 180° (interior angles on the same side of transversal)
x° = 180° - 120°
x° = 60°
x = 60
x° + y° = 140° (alternate angles)
60° + y° = 140°
y° = 140° - 60°
y° = 80°
y = 80
The measure of angle ∠x is 60° and ∠y is 80°.
What are Alternate Interior Angles?Alternate Interior Angles is defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.
Since angle ∠x and ∠120° are interior angles on the same side of transversal.
So, x° + 120° = 180°
x° = 180° - 120°
x° = 60°
x = 60
Since angle ∠x° and angle ∠y° are alternate angles
So, x° + y° = 140°
Substitute the value of x = 60 in above equation,
60° + y° = 140°
y° = 140° - 60°
y° = 80°
Hence, the measure of angle ∠x is 60° and ∠y is 80°.
