3) Write an equation of a
line that has a slope of -3
and goes throughh
the
point (-4, 6)
m = -3
point = (-4,6)
You need to put this in point slope form.

y - 6 = -3x - 12
add 6 to 12
y = -3x - 6
answer : y=-3x-6
A right triangle is ____ a scalene triangle.
Always, sometimes, or never
Answer: Sometimes
Step-by-step explanation:
This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas

(dont write random answers pls)
look at the pic attached:
Answer
the answer would be
D(5,-2).
Answer:
D(-6, 1)
Step-by-step explanation:
To determine the solution we can start by calculating the slope of AB;
A(-1, 4), B(2, -5)
m = -5 - 4 / 2 - (-1) = -9 / 3 = -3
Then CD, if to be perpendicular, should have the 'negative reciprocal' of the slope of AB. In other words it should have a slope of 1/3. We are given point C as (3, 4) so let's take each of the given options for point D, and find the slope using the two points. If the slope is 1/3rd then that is the correct option.
Now I already know the answer, so instead of going through all the options I will just check the slope with the correct answer choice. You will find the slope to be 1/3rd;
C(3, 4), D(-6, 1)
m = 1 - 4/- 6 - 3 = -3/-9 = 1/3rd
Correct, as you can see
So your solution is option c
what is the surface area of this rectangular rectangular prism (pic attached)
line passes through points (5, 8) and (10, 5). Line b is parallel to line a. what is the slope of line b??
Answer:
-3/5
Step-by-step explanation:
Let's go from the point (5, 8) to the point (10, 5). We can see immediately that x (the 'run') increases by 5 and y (the 'rise') decreases by 3. Thus, the slope of the line connecting these two points is m = rise/run = -3/5.
Both of these lines have the slope -3/5, given that they are parallel lines.

Answer:
Angle 3= 37 degrees, Angle 2 = 143 degrees, Angle 4= 143 degrees
Step-by-step explanation:
Angle 3 is across from Angle 1 so they are equal to each other. Now to find Angles 2 and 4, cover angles 2 and 3 with your hand so you are just looking at 1 and 4, they are on a line. Lines are 180 degrees, so since angle 1 we know is 37 degrees, then 180-37= 143 degrees for angle 4. Now, 2 and 4 are opposites of each other, and share the same value of 143 (just like how we found angles 1 and 3 to be equal bc they are across from each other)

Mr. Hudson's bill when taking his family to a restaurant for dinner was $65. He used a discount card for 15% off and left a 20% tip on the original amount of the bill. Complete the statements to determine how much Mr. Hudson spent at the restaurant. The amount of Mr. Hudson's bill after the 15% discount was $ . Mr. Hudson left $ for a tip. Mr. Hudson spent $ at the restaurant.
Answer:
Amount of bill after discount = $55.25
Amount of tip left = $13
Total money spent at the restaurant = $68.25
Step-by-step explanation:
Original bill amount of Mr. Hudson = $65
Discount card value = 15% of the bill
Tip offered = 20% of the original amount
To find:
Amount of bill after the discount of 15%.
Amount of tip left.
Total amount spent in the restaurant.
Solution:
Let us apply the percentage here to find the values of total discount, total tip offered.
Discount = 15% of $65
[tex]\Rightarrow \dfrac{15}{100} \times 65 = \$9.75[/tex]
Amount of bill after discount = $65 - $9.75 = $55.25
Amount of tip left = 20% of $65
[tex]\Rightarrow \dfrac{20}{100} \times 65 = \$13[/tex]
Total money spent at the restaurant = Amount of bill after discount + tip offered = $55.25 + $13 = $68.25
The answers are:
Amount of bill after discount = $55.25
Amount of tip left = $13
Total money spent at the restaurant = $68.25

Factor 72x−18xy
Find the Factor of 72x-18xy
Answer:
4x and (1-y)
Step-by-step explanation:
4x(1-y)
this is my answer
The factors of the expression are 18x and 4-y
Given the expression 72x - 18xy
Find the factor of each term:
72x = 18 * 4 * x
18xy = 18 * x * y
Since 18x is common to both terms, hence the factored form is expressed as:
72x - 18xy = 18x (4 - y)
The factors of the expression are 18x and 4-y

I need help I need the answer
Answer:
t ≤ 12/23
Step-by-step explanation:
-48t + 2 ≤ -71t + 14
You would need to get all the numbers on one side and all the variables on the other side.
-48t + 2 -2 ≤ -71t + 14 -2 → -48t ≤ -71t + 12
-48t + 71t ≤ -71t + 71t + 12 → 23t ≤ 12
23t ÷ 23 ≤ 12 ÷ 23 → t ≤ 12/23
What is the value of s ?
Please help
No guessing
Answer:
s = 17Step-by-step explanation:
use Pythagorean theorem a² + b² = c²
where a = 8
b = 15
c = s (which is unknown)
plugin values into the formula:
a² + b² = c²
8² + 15² = s²
s = √(64 + 225)
s = √289
s = 17
Gail has $100 and wants to have her hair styled for the prom. The salon charges $56 for a hair styling. Gail plans to leave a 20% tip. In dollars, how much money will she have left after she pays the hair stylist?
Answer: She has left $32.8 after she pays the hair stylist.
Step-by-step explanation:
Money Gali has = $100
Charge per hair style = $56
Tip percent = 20%
Total charge for hair styling = Charge per hair style + Tip
= $ (56+ 20% of 56)
= $ (56+0.2 x 56)
= $ (56+11.2)
= $ 67.2
Money left = Money Gali has - Total charge for hair styling
= $ (100-67.2)
= $ 32.8
Hence, she has left $32.8 after she pays the hair stylist.
