Step-by-step explanation:
What is the equation of the line passing through the points (-2, 2) and (3,-1)?
A.
5
y=--x+ -
3 3
4
B.
C.
y = x-4
3 4
y=-*+-
5 5
D
y = -3x + 8
Answer:
Step-by-step explanation:
+ Because of " the line passing through the points (-2, 2) and (3,-1)", that means this line has its equation y = ax + b where
[tex]a=\frac{2-(-1)}{-2-3} =\frac{2+1}{-5} =-\frac{3}{5}[/tex]
So we write its equation: y = -3/5 x + b.
+ Then, now, we replace x = -2 and y = 2 into y = -3/5 x + b for finding b like:
2 = -3/5 * (-2) + b or 2 = 6/5 + b
so b = 2 - 6/5 = 4/5.
And this line has its equation: y = -3/5 x + 4/5.
Mẹthod 2:
we have a formule for a line that passes 2 points [tex](x_{0},y_{0}) , (x_{1},y_{1}) ,x_{0}\neq x_{1}[/tex]
Here is: [tex]\frac{x-x_{0} }{x_{1}-x_{0} } = \frac{y-y_{0} }{y_{1}-y_{0} }[/tex]
Then, we can write for this case:
[tex]\frac{x-(-2)}{3-(-2)} =\frac{y-2}{-1-2} \\\frac{x+2}{5} =\frac{y-2}{-3} \\-3(x+2) = 5( y-2)\\-3x-6=5y-10\\3x+5y-4=0\\or\\y=-\frac{3}{5}x+\frac{4}{3}[/tex]

Answer:
x = 0.3, y = 5.3, z = 17.3
Step-by-step explanation:
Since given question is incomplete, so here is the complete table for the distance from the mean.
Temp (°F) 29 38 45 31 50 58 62
Distance from the mean 15.7 6.7 x 13.7 y 13.3 z
It's given that the mean of the data is 44.7
Since distance from the mean of a data is the absolute value of the difference of data and mean,
Therefore, distance from the mean of the data will be,
x = |44.7 - 45| = 0.3 (absolute value of the difference)
y = |44.7 - 50| = 5.3
z = |44.7 - 62| = 17.3
Answer:
x = 0.3
y = 5.3
z = 17.3

Put in order rational numbers
Answer:
[tex]-\frac{26}{40}[/tex]
[tex]-\frac{9}{20}[/tex]
[tex]\frac{12}{25}[/tex]
Step-by-step explanation:
Divide each individually.
[tex]-\frac{9}{20}=-0.45[/tex]
[tex]\frac{12}{25}= 0.48[/tex]
[tex]-\frac{26}{40}=-0.65[/tex]
Since you have to order them from least to greatest, begin by the negative number that is farthest from 0. In this case, -0.65, the next negative number would be -0.45 and finally we only have one positive number 0.48
Which number line best shows how to solve - 2 - (- 10) ?
Answer:
A)
Step-by-step explanation:
As a rule of thumb, two negative signs directly next to each other becomes a positive sign. Simplify:

Find the 100th term in the arithmetic sequence 0,5,10,15
Answer:
easy peasy,
the 'n' th term of any arithmetic sequence can be found with the following formula
=> a + ( n-1) d, [where 'a' if the first term of the sequence, 'n' the number of term we need to find, and 'd' being the common difference between each two consecutive term of the sequence)
all in this case would be,
a = 0
n = 100
d = +5
hence the 100th term would be,
=> 0 + (100 - 1) 5
=> 99 x 5
=> 495

If PQ is tangent to circle R at point Q and PS is
tangent to ⊙R at point S, what is the perimeter
of quadrilateral PQRS?
Answer:
Perimeter of the quadrilateral PQRS is 25 units
Step-by-step explanation:
From the figure attached,
PQ is a tangent to the given circle so m∠PQR = 90°
Now we apply Pythagoras theorem in the ΔPQR,
PR² = PQ² + QR²
(PT + TR)²= PQ² + 5²
(4 + 5)² = PQ² + 25
81 = PQ² + 25
PQ = √(81 - 25)
= √56
≈ 7.5 units
PQ ≅ PS ≅ 7.5 units
[Since measures of tangents drawn from a point to a circle are always equal]
Perimeter of PQRS = PQ + QR + RS + PS
= 7.5 + 5 + 5 + 7.5
= 25 units
Therefore, perimeter of the quadrilateral PQRS is 25 units.
Answer:
10 + 4 square root 14
Step-by-step explanation:
so the person below or above me said 25 units and they are not wrong it just the did have it in a simple equation like this ^
so 4 square root 14 = 14.9 or 15
then 10 + 15 = 25 units
so the correct answer is 10 + 4 square root 14

The reference angle for an angle whose measure is -440° is _____.
Answer:
The reference angle is the acute angle formed by the terminal side of an angle in standard position and the x-axis
Step-by-step explanation:
-440° will be in the 1st quadrant
We solve by adding 360° to it till it becomes positive
-440°+360°= -80°
-80°+360°=280°
The equivalent value will become
360°-280°= 80°
Answer:
The reference angle for an angle whose measure is -440° is 80°.
Step-by-step explanation:
The cycles for angles range from the traditional 0° to 360° and subsequent 360° ranges befor and after this traditional intervals, also have the same properties.
So, the ranges that exist and correspond to the traditional 0° to 360° include
0° to 360°
360° to 720°
720° to 1080°
And in the negative direction, we have
-360° to 0°
-720° to -360°
We can see that -440 is in the range of
-720° to -360°
Using the traditional 0° to 360° to compare this range of -720° to -360°, let x represent the reference angle in the traditional range that we require.
-720° ------ 0°
-440° ------ x
-360° ------ 360°
Using interpolation,
[-440° - (-720°)]/[-360° - (-440°)] = (x - 0°)/(360° - x)
(280/80) = x/(360-x)
3.5 = x/(360-x)
3.5(360 - x) = x
1260° - 3.5x = x
4.5x = 1260°
x = (1260°/4.5) = 280°
But, the reference angle is the smallest angle that one can make from the terminal side of an angle (that is, where the angle ends) with the x-axis. It uses the x-axis as its frame of reference.
So, 280° is a fourth quadrant angle, whose equivalent in the first quadrant is 360° - 280° = 80°
Hope this Helps!!!

What is the area of the shaded sector of the circle?
a. 20
b. 25
c. 100
d. 72
Answer:
i think its 25 because like if 72 is the shaded part then it can't be the answer 100 wouldn't be the answer because it is too high and 20 wouldn't be the answer because it is too low so 25 is my reasonable answer.
Step-by-step explanation:
Since the area to me is 25 then we would do 360 x 25 = 9000
the you do 9000 / 36 i got 36 by doing 360 / 10
After that you you do 9000 / 36 which gives you 2.5
Last i did 2.5 x 10 which gave me 25
