what is the equation of the graphed line in point-slope form?
a. y – 1 = (x + 3)
b. y – 1 = (x – 3)
c. y + 1 = (x – 3)
d. y + 1 = (x + 3)
Answers
slope = (-3 - 1) / (-3 - 3) = -4/-6 = 2/3
y - y1 = m(x - x1)
slope(m) = 2/3
(3,1)...x1 = 3 and y1 = 1
now we sub
y - 1 = 2/3(x - 3) <==
Answer:
[tex]y-1 = \frac{2}{3}(x-3)[/tex]
Step-by-step explanation:
To find the equation of graphed line we pick two points from the line
(3,1) and (-3,-3)
Equation of a line is y=mx+b
where 'm' is the slope and b is the y intercept
slope [tex]m= \frac{y2-y1}{x2-x1} =\frac{1+3}{3+3} = \frac{2}{3}[/tex]
we use point slope formula
y-y1= m(x-x1)
here point(x1,y1) is (3,1) and slope m = 2/3
Plug in all the value
[tex]y-1 = \frac{2}{3} (x-3)[/tex]

The area of the segment of circle 'C' is 353.66 sq. units.
Therefore, option (A) is the correct answer.
What is a segment of a circle?"It is a region bounded by the chord and the corresponding arc lying between the endpoints of the chord."
Formula to calculate the area of the segment of circle:[tex]A = (\frac{1}{2} ) \times r^2\times [(\frac{\pi}{180}) \theta - sin \theta][/tex]
where, angle is measured in degree
For given example,
radius r = 24,
angle [tex]\theta[/tex] = 120°
In given diagram, the area of the segment of circle is given by the shaded part.
Using the formula of the area of the segment of the circle,
⇒ [tex]A = (\frac{1}{2} ) \times r^2\times [(\frac{\pi}{180}) \theta - sin \theta][/tex]
⇒ [tex]A = (\frac{1}{2} ) \times (24)^2\times [(\frac{\pi}{180} \times 120) - sin(120)][/tex]
⇒ [tex]A = 288\times [\frac{2\pi}{3} - 0.87][/tex]
⇒ [tex]A=353.66[/tex] sq. units.
Therefore, the area of the segment of circle 'C' is 353.66 sq. units.
Therefore, option (A) is the correct answer.

Mary gets an annual salary of $56,780. if she is paid semimonthly, what is the amount of her semimonthly gross pay?
Answers
$567.20 * 26
There are 12 months in a year. If Mary is paid semimonthly, she is paid twice a month, or 24 times a year.
$56,780 / 24
Mary gets paid $2,365.83 on a semimonthly period basis.
Mary gets around $56,780 per year.
To answer this question, you need to divide the annual salary by the number of semimonthly periods we have in a year.
There are 12 monthly periods. Semi means half so a month has 2 semi periods.
The number of semimonths in a year are:
= 12 months x 2
= 24 semimonths
Mary's semimonthly pay is therefore:
= Annual salary / Number of semimonthly periods
= 56,780 / 24
= $2,365.83
In conclusion, Mary's semimonthly pay is $2,365.83.

Which is an equivalent form of the equation 4x-y= 14
Answers
-y = 14 - 4x
y = -14 + 4x
Answer:
y = 4x - 14 is equivalent from of y = 4x - 14.
Step-by-step explanation:
Given : 4x-y= 14
To find : Which is an equivalent form of the equation.
Solution : We have given 4x - y = 14.
We can write it in slope intercept form y = mx + b
Where, m = slope , b = y intercept.
4x - y = 14.
On subtracting both sides by 4x
- y= -4x + 14.
On dividing both sides by -1.
y = 4x - 14.
Therefore, y = 4x - 14 is equivalent from of y = 4x - 14.

Answer:
21.
Step-by-step explanation:
We have been given that Reaner Recycling shreds 7/8 ton of aluminum each day.The machines can shred 1/24 ton aluminum per cycle.
To find the number of cycles needed to shred the aluminum, we will divide amount of aluminium by 1/24 as:
[tex]\text{Number of cycles}=\frac{7}{8}\div \frac{1}{24}[/tex]
Convert into multiplication problem by flipping the 2nd fraction:
[tex]\text{Number of cycles}=\frac{7}{8}\times \frac{24}{1}[/tex]
[tex]\text{Number of cycles}=\frac{7}{1}\times \frac{3}{1}[/tex]
[tex]\text{Number of cycles}=7\times 3[/tex]
[tex]\text{Number of cycles}=21[/tex]
Therefore, 21 cycles will be needed to shred the aluminum.

△JKL≅△QRS.
What is m∠Q?
Answers
we know that
If △JKL≅△QRS
then
the corresponding angles are congruent
so
m∠Q=m∠J
m∠R=m∠K
m∠S=m∠L
we have
m∠J=[tex]37\°[/tex]
therefore
the answer is
m∠Q=[tex]37\°[/tex]
Answer:
m∠Q = 37°
Step-by-step explanation:
It has been given that ΔJKL ≅ ΔQRS
∠J = 37° and ∠K = 105°
Since these triangles are congruent so we will apply the condition of ASA (theorem of congruence)
In ΔJKL and ΔQRS sides JK and QR along with their corresponding angles will be equal.
Side JK = side QR
and ∠K = ∠R = 105°
∠J = ∠Q = 37°
Therefore m∠Q = 37° will be the answer.
Write a function rule for the area of a rectangle whose length is 6 ft more than its width. What is the area of the rectangle when its width is 12 ft?
Answers
=> x+6 will be the length.
Function: x(x+6)= x^2+6x
Area= 12^2+6.12= 216 ft
The area of the rectangle is 72 square ft and this can be determined by using the formula of the area of the rectangle.
Given :
Length is 6 ft more than its width.
The following steps can be used in order to determine the area of the rectangle when its width is 12 ft:
Step 1 - Let the length of the rectangle be 'L' and the width of the rectangle be 'W'.
Step 2 - According to the given data, length is 6 ft more than its width that is:
L = 6 + W
Step 3 - The formula of the area of the rectangle is given below:
A = LW
Step 4 - Substitute the value of 'L' in the above expression.
A = (6 + W)W
Step 5 - Now, at W = 6ft the area of the rectangle becomes:
A = (6 + 6)6
A = 72 square ft.

-9 and = 5 look like the ones so we write
3x^2 - 9x + 5x - 15
Now factor this by grouping:-
= 3x(x - 3) + 5(x - 3)
x - 3 is common to the 2 parts so we have:-

angle efg and angle gfh are a linear pair, the measure of angle efg equals 4n+20, and measure of angle gfh equals 3n+13. what are the measures of angle efg and angle gfh?
Answers
Answer:
∠EFG=104° and ∠GFH=76°
Step-by-step explanation:
Given information:∠EFG = (4n+20)°, ∠GFH = (3n+13)° and ∠EFG and ∠GFH are a linear pair.
If two angles are a linear pair, then the sum of those angles is 180°.
It is given that ∠EFG and ∠GFH are a linear pair.
[tex]\angle EFG+\angle GFH=180^{\circ}[/tex]
Substitute the given values.
[tex](4n+20)+(3n+13)=180[/tex]
Combined like terms.
[tex](4n+3n)+(20+13)=180[/tex]
[tex]7n+33=180[/tex]
Subtract 33 from both sides.
[tex]7n+33-33=180-33[/tex]
[tex]7n=147[/tex]
Divide both sides by 7.
[tex]n=21[/tex]
The value of n is 21.
[tex]\angle EFG=4n+20=4(21)+20=104^{\circ}[/tex]
[tex]\angle GFH=3n+13=3(21)+13=76^{\circ}[/tex]
Therefore, the measure of ∠EFG and ∠GFH are 104° and 76° respectively.
The length of one base of a trapezoid is 19 less than five times the length of the other base. If the trapezoid has a height of 18 feet and an area of 477 ft squared, find the length of the longer base.
Answers
suppose the length of one base is x, then the other base is 5x-19
[(x+5x-19)*18]/2=477
[6x-19]*18=954
6x-19=53
6x=72
x=12
The longer base is 5*12-19=41
The length of the shorter base of the trapezoid is found by solving the equation generated by using the formula for the area of a trapezoid. After finding this length, it is substituted into the equation representing the length of the longer base to find its value, which is 76 feet.
Explanation:To solve this problem, let's denote the length of the shorter base of the trapezoid as 'a'. According to the problem, the length of the longer base is then 5a - 19. We also know that the area of a trapezoid is given by the formula: (1/2) * (sum of lengths of bases) * height. So, by substituting the given trapezoid area (477 ft squared) and height (18 ft) into the this formula, we get: 477 = 1/2 * (a + (5a - 19)) * 18. Solving this equation will give us the value of 'a'. As calculating 'a' we find it to be 19. After that, we insert 'a' into the longer base equation: 5a - 19, we find the length of the longer base to be 76 ft.
