plz help
Answer:
Slope-intercept form of the line:
y = mx + bPoint-slope form of the line:
y - y1 = m(x - x1)------------------------------------
Points:
(2;9) (4,17)The slope:
m = (17 - 9)/(4 - 2) = 4The line:
y - 9 = 4(x - 2)y = 4x - 8 + 9y = 4x + 1----------------------------------
Points:
(3; -17) (-3;13 )The slope:
m = (13 - (-17)) / (-3 - 3) = 4/ -6 = -2/3The line:
y - (-17) = -2/3(x - 3)y = -2/3x + 2 - 17y = -2/3x - 15Which is equivalent to 3 X 3 X 3 X 3 X 3 A 3x5 B 3^3 C 5^3 D 3^5

Factor each polynomial using the Greatest Common Factor.
Answer:
–9(3x³ – 8x + 9)
Step-by-step explanation:
–27x³ + 72x – 81
The above equation can be factorised as follow:
–27x³ = –3 * 3 * 3 * x * x * x
72x = 2 * 2 * 2 * 3 * 3 * x
–81 = –3 * 3 * 3 * 3
Common factor = 3 * 3
Greatest common factor = 9
Thus,
–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)
–27x³ + 72x – 81 = –9(3x³ – 8x + 9)
Below. What is m∠1?
m∠1 =
Answer:
m∠1 = 70°
Step-by-step explanation:
Step 1
Sum of angles on a straight line = 180°
Hence:
180° - 101°
= 79°
Sum of interior angles in a triangle = 180°
Hence
m∠1 = 180° - (79 ° + 31°)
m∠1 = 70°
Write 90% as a fraction or mixed number in simplest form.

A certain triangle, one angle measures ten degrees more than the second angle and ten degrees less than the third angle. What is the measure of the smallest angle?
Answer:
50°
Step-by-step explanation:
Let :
Let the angle = x
Second angle = x + 10
Third angle = x - 10
Sum of angles in a triangle = 180
x + (x + 10) + (x - 10) = 180
x + x + 10 + x - 10 = 180
3x = 180
x = 180 / 3
x = 60
Smallest angle :
x - 10 = 60 - 10 = 50°

The quotient for the given problem is 198.
What is division?
Division is a simple operation in which a number is divided. The splitting of a large group into smaller groups such that every group will have an equal number of items.
By using division concept, we can find the quotient when the divisor is divided by the dividend.
The divisor is 15048
The dividend is 76
Division is performed by using the division operator ÷
⇒ [tex]15048[/tex] ÷ [tex]76[/tex]
⇒ [tex]198[/tex]
Hence the quotient for the given problem is 198.

Carter bought a pair of shoes online for $64. He used a coupon code to get a 10% discount. The website also applied a 5% processing fee to the price after the discount. How much did Carter pay for the processing fee? Round to the nearest cent.
Answer:
$60.48
Step-by-step explanation:
Price after the discount = original price - discount
discount = 10% x 64 = $6.4
$64 - $6.4 = $57.60
processing fee = 57.60 x 5% = $2.88
Price paid = $2.88 + $57.60 = $60.48

Standing on a cliff 380 meters above the sea, Pat sees an approaching ship and measures its angle of depression, obtaining 9 degrees. How far from the shore is the ship? Now Pat sights a second ship beyond the first. The angle of depression of the second ship is 5 degrees. How far apart are the ships?
Answer:
(a). 2399.23 meters.
(b). 1944.19 meters apart.
Step-by-step explanation:
We have been given that standing on a cliff 380 meters above the sea, Pat sees an approaching ship and measures its angle of depression, obtaining 9 degrees.
(a) We are asked to find how far from the shore is the ship.
We know that tangent relates opposite side of a right triangle with its adjacent side.
Therefore, the ship is approximately 2399.23 meters away from the shore.
Therefore, the both ships are approximately 1944.19 meters apart.

Find the probability. Write answer as a reduced fraction using the forward slash (/).
You have 10 blue marbles, 8 red marbles, and 6 white marbles in a bag. You pick a red marble and put it back, pick a blue marble and put it back, and then pick a red or white marble.
Answer: depends on which probability you want (tell me and I’ll edit)
Step-by-step explanation:
10 blue
8 red
6 white
24 total
Pick a red marble: 8/24 or 1/3
Pick a blue marble: 10/24 or 5/12
Pick red or white: 14/24 or 7/12
do you want to know the probability of doing all that (pick red, put back, pick blue, put back, then pick red or white)? Or just the probability of each outcome?
