Find the slope of AB. If it is a fraction such as 1/2, write as 1/2 without spaces. (3 points)
Answer:
The slope of AB is 4/3
Step-by-step explanation:
The Slope of a Line
If a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
It's required to find the slope of the line AB shown in the figure. The coordinates of the endpoints are A(-3,2) B(0,6), thus the slope is:
[tex]\displaystyle m=\frac{6-2}{0+3}[/tex]
[tex]\displaystyle m=\frac{4}{3}[/tex]
The slope of AB is 4/3
Find the length for segment AB. Round to the nearest unit if necessary and enter as a whole number.
Answer:
The length for segment AB is 5 units
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We must find the length for the segment AB. The coordinates of the endpoints are A(-3,2) B(0,6).
Calculating the distance:
[tex]d=\sqrt{(0+3)^2+(6-2)^2}[/tex]
[tex]d=\sqrt{3^2+4^2}[/tex]
[tex]d=\sqrt{9+16}[/tex]
[tex]d=\sqrt{25}[/tex]
d = 5 units
The length for segment AB is 5 units

Which of the following shapes are rhombuses ? Choose two correct answers !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!
Answer:
Hi there! Your answer is C and D
Step-by-step explanation:
You might know that a Rhombus is a special type of parallelogram whose all sides are equal. The difference between a square and a rhombus is that all angles of a square are right angles, but the angles of a rhombus need not be right angles. So, a rhombus with right angles becomes a square. B is not because all sides are equal and it has right angles. A is not because it does not have equal sides. I hope this helps! :]

you buy 6 apples for $2.70 write and equation that can be used to express the relationship between the total price t and the number of apples a you buy.
1. t= 2.70a
2. t=0.45a
3. t=6a
t= 2.22a
Answer:
The correct answer is: 2. t=0.45a
Step-by-step explanation:
Let t be the price of apples
and a be the number of apples
The price and quantity are directly proportional
[tex]t \propto a[/tex]
Removing the proportionality symbol introduces a proportionality constant in the equation
[tex]t = ka[/tex]
So far we know that cost of 6 apples is $2.70
Putting in the equation
[tex]2.70 = k (6)\\k = \frac{2.70}{6}\\k = 0.45[/tex]
Putting the values of k will give us:
[tex]t = 0.45a[/tex]
Hence,
The correct answer is: 2. t=0.45a

Jadynn's washing machine holds l,086 liters of water. how much water dose it hold in gallons? A gallons is approximately 3.79 liters. round to the nearest tenth
Answer:
286.5 gallons of water
Step-by-step explanation:
1,086 ÷ 3.79= 286.5435356
Round to the nearest tenth
286.5
Answer:
286.54 gallons
Step-by-step explanation:
You have 1,086 liters and you are trying to find how many gallons it is
Luckily you are given how many liters go into a gallon
So from there it's simple division
1,086/3.79 = 286.5435356200528
Now, it tells you that you only need to round to the nearest tenth. And since the nearest tenth isn't greater than 5, you can just leave it as 286.54
So, 286.54 gallons is the amount that the washing machine holds
I need help on 13 it has to be standard form
5(x – 3) = -15 + 10(x + 3) – 5x
Please help
Answer:
There are no solutions.
Step-by-step explanation:
Expand 5(x-3) 5x-15
Expand -15+15=5x+15+15
Add 15 to both sides
5x-15+15=5x+15+15
Simplify
5x=5x+30
Subtract 5x from both sides
5x-5x=5x+30-5x
0=30

solve for X. y=x-5 and y=6 simplify your answer as much as possible.
Answer:
x=11
Step-by-step explanation:
6=x-5
11=x
Answer: The answer is 11.
Step-by-step explanation: If y=6 and the problem is y=x-5 Then you could do 5+6 (since we know y=6) and get the answer of 11. To check it the answer you can do 11-5 which equals 6.

solve the equation
3^2x-1=27^x-1
Step-by-step explanation:
3^(2x) - 1 = 27^x - 1
3^(2x) = 27^x
3^(2x) = (3^3)^x
3^(2x) = 3^(3x)
Therefore 2x = 3x and x = 0.
