Triangle ACB with coordinates A(0,0), C(2,0), and B(2,4) is similar to triangle BED. If vertex D has coordinates (6,12), what are the coordinates of vertex E?
Answer:
A right triangle is a triangle that has 90 degrees angle in one of its parts. You are given two points that have coordinate:
x1,y1= (-2, 4)
x2,y2= (-1,1)
To make the angle 90 degrees, there is two possible third point coordinate:
1. x1, y2 = (-2,1)
2. x2, y1= (-1,4)
The right triangle would be option C: (-2,1)
Option A and B is not a right triangle
Step-by-step explanation:
Answer:
the coordinates of vertex E is (6,0)
C(2,0),compare this to(2,4)
same x.but y=0
(6,0)comparing to (6,12)
we get it

Find the slope and type in the correct code.
Answer:
DFBG
Step-by-step explanation:
At any point in time;
slope m = (y2-y1)/(x2-x1)
1. (3,19) and ((-1,-13)
m = (-13-19)/-1-3 = -32/-4 = 8
Letter here is D
2. we pick out two points to use here from the line
These are ((0,1) and (2,5)
Slope is ;
(5-1)/2-0 = 4/2 = 2
Letter here is F
3. We pick any two points
(1,-8) and (4,-32)
slope =
(-32 + 8)/4-1 = -24/3 = -8
Letter here is B
4. Slope = 8 + 10/0-9 = 18/-9 = -2
letter here is G

Answer:
-3/2x +2
Step-by-step explanation:
To find slope: y value - y value over x value - x value
5-(-4) = 9
-2 -4 = -6
9/-6 = -3/2 after you divide each by gcf of 3
y intercept : plug in your y and x values (and your slope ) into the equation: y = mx+b (slope intercept form)
point 1 (-2,5): 5 = (-3/2)(-2)+b
5 = 3+b (subtract 3 from both sides)
2 = b (your y intercept)
Answer: y=[tex]\frac{-3}{2}[/tex]x+2
Step-by-step explanation:
1. Find the slope of the two coordinates by using the slope-intercept form:
Slope intercept form=(y₂-y₁)/(x₂-x₁)
(-4-5)/(4-(-2))
(-9)/(4+2)
-9/6 or -3/2
2. Now that we have the slope for these two coordinates, plug them into the point-slope formula.
Equation for point-slope: y-y₁=m(x-x₁), where m=slope
y-5=[tex]\frac{-3}{2}[/tex](x-(-2)
y-5=[tex]\frac{-3}{2}[/tex](x+2)
y-5=[tex]\frac{-3}{2}[/tex]x-[tex]\frac{6}{2}[/tex]
y-5=[tex]\frac{-3}{2}[/tex]x-3
(Add 5 to both sides)
y=[tex]\frac{-3}{2}[/tex]x+2

Please actually answer this, don't just type random stuff i swear. Okay, has this been happening to anyone else? What's happening is I can't get a tutor at all, I am doing Mathematics too like- can someone help me, please don't answer this just for points.
Answer:
Finding a tutor for mathematics? If that's the problem
Step-by-step explanation:
Try asking friends, family, close people in your family about mathematics. Maybe they have the same problem and somehow got over it by studying, asking questions, or they have a tutor, etc
Try using that same method that they used. If none of them have problems, ask your parents about that. They might be willing to sit down and teach you a little bit...
I have always had problems with math so I am sorry if it doesn't work out for you

Here are 5 lines on a coordinate grid:
Write equations for lines:
Answer:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
For the particular case of horizontal lines, those will be of the form:
y = constant.
The vertical lines will be of the form:
x = constant.
Let's start with line a, this is a vertical line, then will be:
x = constant.
To see the value of the constant, you need to see in which point it intersects the x-axis, in this case is in -4, then line a will be:
x = -4
For line b we have the same reasoning, in this case the line intersects the x-axis at x = 4, then line b is: x = 4.
Now for the horizontal lines:
Line c will be of the form:
y = constant
To find the value of the constant you need to see in which point the line intersects the y-axis.
In this case the line intersects the axis at y = 4.
Then this line can be written as: y = 4
For line d, we can see that it intersects the y-axis at -2, then this line will be written as:
y = -2.
For the case of line e we can use the first thing we wrote, let's find two points that belong to this line.
(0 , 1) and (4, -2)
Then the slope will be:
a = (-2 - 1)/(4 - 0) = -3/4
y = -(3/4)*x + b
To find the value of b, we can just replace the values of one of the points in the equation. I will use the point (0, 1), this means that we must replace x by 0, and y by 1.
1 = -(3/4)*0 + b
1 = b
Then the equation for line e is:
y = -(3/4)*x + 1.
what are the slope and y-intercept for the graph of y-3x=-1
Answer:
Step-by-step explanation:
Think of the equation y = mx + b
So the m is the slope and the b is the y-intercept
m/slope= 3 b/y-intercept= -1

Andrew purchased a coat for $50.00 on sale for 25% off. What was the cost of the coat after the discount not including tax?
Answer:
$37.50
Step-by-step explanation:
Sale = $50.00 x 25% = $12.50
=> The coat after the discount = $50.00 - $12.50 = $37.50
$37.50
Step-by-step explanation:
Sale = $50.00 x 25% = $12.50
=> The coat after the discount = $50.00 - $12.50 = $37.50

Write an expression to show how much it costs per week to keep the 8 adults x where the number of pounds one adults in a day. Simplify your expression
Answer:
y = 56xStep-by-step explanation:
Given the amount to keep one adult in a day to be x
Since 7 days = 1 week
Amount it will take to keep one adult for a week will be 7x
one adult = 7x pounds
To get the expression that show how much it costs per week to keep the 8 adults, we will say;
8 adults = y pounds
where y is the required amount
Solving both expressions
one adult = 7x pounds
8 adults = y pounds
Cross multiply
1 * y = 7x * 8
y = 56x
Hence the required expression is y = 56x
Equation: -2(2x + y) = 28.
Answer:
x=-14-y/2
Step-by-step explanation:
divide both sides by -2
-2(2x+y)/-2=28/2
simplify
2x+y=-14
subtract y from both sides
2x+y-y=-14-y
simplify
2x=-14-y
divide both sides by 2
2x/2=-14/2-y/2
simplfy
x=-14-y/2

I need help with this equation. I'm not that smart so I can't figure it out-
Answer:
x = 0
Step-by-step explanation:
In order to solve for x, first combine both fractions on the left
To add 4x-2/8 + 3+x/4 first find the least common denominator of 8 and 4
It's 8 so multiply the numerator and denominator of 3+x/4 by 8, you would get:
8x+24/32
Multiply 4x-2/8 by 4, you will get:
16x-8/32
Now you can add 16x-8/32 + 8x+24/32, you would get:
24x+16/32
Now you can start to solve for x
Your new equation is 24x+16/32 = 1/2
To solve for x, first multiply diagonally, then solve like a regular equation.
Multiply 24x+16 by 2 to get 48x+32
Then multiply 32 by 1 to get 32
Your new equation is 48x+32=32
Now subtract 32 by 32 to get 48x=0
Now divide 48 by 0 to get x=0

Explain why it is important to line up decimal points when you are adding and subtracting decimals. Use the problem 6.32 – 0.5 in your explanation
Answer:
Kindly check explanation
Step-by-step explanation:
When performing addition and subtraction of decimals, it is important to arrange the numbers being added or subtracted such that the decimal points are in line. This is particularly important so that the place value of the numbers are in accord.
To simplify, when then decimals are in line, then the tenth value of the first number will be added to the tenth value of the second. Without this arrangement, one might be adding the hundredth placed value to the tenth or unit value which is mathematically incorrect and will yield a wrong result.
For instance :
6.32 - 0.5
Here, when the decimal point of each number is in line, the tenth placed value of the first number (3) matches the tenth placed number of the second number (5) and all others also fall in place automatically.

¿Cuál debe ser el precio de venta de cada lápiz para que el ingreso total sea máximo? El ingreso total l(v) que se obtiene por la venta de lapices esta dado por la función l(v)=-2v^2+500v, donde v es el precio de venta de cada lápiz en pesos.
Responder:
125 pesos
Explicación paso a paso:
Dado el ingreso total l (v) obtenido de la venta de lápices por la función
Yo (v) = - 2v ^ 2 + 500v
v es el precio de venta de cada lápiz
Para que el ingreso total sea máximo, entonces dI / dv debe ser cero, es decir, dI / dv = 0
dI / dv = -4v + 500
Dado que dI / dv = 0
0 = -4v + 500
4v = 500
Dividir entre 4
4v / 4 = 500/4
v = 125
De ahí que el precio de venta de cada lápiz sea para que el ingreso total sea máximo es de 125 pesos
