Point X has coordinates (-4, -5) and point y has coordinates (--1, --5 ) which expression models the distance between points X and Y ?
Answer: The last expression shows the result of 3 so it models the distance between x and y.
Step-by-step explanation:
First you will have to find the distance between the two points by square the x coordinates and squaring the y coordinates to find their sum .
-4 - (-1) = -3
-5 - ( -5) = 0
-3^2 + 0^2 = d^2 where d is the distance
9 = d^2
d= 3
The distance is 3 units
Now evaluate which expression have a solution as 3.
The last expression is the answer
the absolute value for -4 is 4 , and the absolute value for -1 is 1 and 4 minus 1 is 3.

Find the value of x. Show your work, congruent triangles
Answer:
x = 12
Step-by-step explanation:
130 + y = 180 {linear pair}
y = 180 - 130
y = 50°
3x - 6 +8x + 4 + 50 = 180 {Angle sum property of triangle}
3x + 8x - 6 + 4 + 50 = 180 {Combine like terms}
11x + 48 = 180
11x = 180 - 48
11x = 132
x = 132/11
x = 12°
What is the equation of this line?
a) y = 3/2x
b) y = -2/3x
c) y = -3/2x
d) y = 2/3x
Answer:
Its A) y=3/2x
Step-by-step explanation:
-3/2x would be the exact opposite of 3/2x it would be the same line but facing the left side because its on the negative side. And the others are not the same as 3/2x.
Sorry if i could not explain that well, but I am 99% sure its A, y=3/2x
At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 from this account for her contact lenses. After 3 months she has $255 left in her account.
Write an equation in slope-intercept form to represent the relationship between the time that has passed and the amount of money left in Monica's account. Let x represent the time in months and y represent the amount of money remaining in the account.
Answer:
An equation in the slope-intercept form is:
[tex]y = 15x+210[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where m is the rate of change or slope and b is the y-intercept
Given
Let x represent the time in months Let y represent the amount of money remaining in the account.Given that every month Monica withdraws $15 from this account for her contact lenses
so, the rate of change or slope = m = 15Given that after 3 months she has $255 left in her account.
i.e. (3, 255)
substituting [tex]m = 15[/tex], [tex]x = 3[/tex] and [tex]y = 255[/tex] in the slope-intercept form to determine the y-intercept
[tex]y = mx+b[/tex]
[tex]255 = 15(3) + b[/tex]
switch sides
[tex]15(3) + b = 255[/tex]
[tex]45 + b = 255[/tex]
[tex]b = 255 - 45[/tex]
[tex]b = 210[/tex]
Thus, the y-intercept b = 210
Now, substituting [tex]m = 15[/tex] and [tex]b = 210[/tex] in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]y = 15x+210[/tex]
Hence, an equation in the slope-intercept form is:
[tex]y = 15x+210[/tex]what is 3whole number minus 1whole number 1/4

What is the rate of change for the linear relationship modeled in the table? (4 points)
x y
-1 10
1 9
3 8
5 7
negative one over two
0
one over two
2
Answer:
-1/2
Step-by-step explanation:
In a linear relationship, the rate of change of one variable with respect to the other is constant. When we talk about change, we're looking for a difference of values.
If we look at the first and second rows, the change in x is 1 - (-1) = 2, while the change in y is 9 - 10 = -1. Usually we refer to these changes as Δx and Δy (read like "delta-x" and "delta-y"), and the rate of change is the number we get by dividing one of these by the other.
The rate of change we're used to seeing, sometimes called the slope, is Δy/Δx. So, using the values we've already found:
[tex]\Delta{x}=2\\\Delta{y}=-1\\\Delta{y}/\Delta{x}=-1/2[/tex]

Step-by-step explanation:
If the wire is in a square and all the sides are 5 inches when you unfold the wire it will be 20 inches long so if the length of the wire ina regtangle is 7 then the width is 3
Answer: 3.
Step-by-step explanation: The answer is 3 because the original shape was a square with all of the sides with the length 5. Because there are 4 sides in a square, the perimeter of the square is 20(5+5+5+5). Now, the square has been reshaped into a rectangle. If one of the side lengths of the rectangle is 7, the opposite and parrallel side has to be 7. 7+7 is 14. Now the expression is perimeter = 14 + 2(missing width). If you plug in 3, that expression is now 14+6, which is 20. Therefore, the missing side width is 3.
How many 1/3 inch cubes does it take to fill a box with width 2 213 inches, length 3 1/3
inches, and height 2 1/3 inches?
Answer:
560 cubes
Step-by-step explanation:
Is 2 213 supposed to read 2 1/3? First calculate the volume of the box
V_box = 8/3 * 10/3 * 7/3 = 560/27 cubic inches
Now calculate the volume of your 1/3 inch cube:
V_cube = 1/3 * 1/3 * 1/3 = 1/27 cubic inches
Now divide the V_box by V_cube:
Number of boxes = (560/27) / (1/27) = (560/27) * (27/1) = 560 cubes

The purple shape is a dilation of the black shape. What is the scale factor of the dilation
Answer:
Scale factor = 1/2
Explanation:
The purple shape is a dilation of the black shape.
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
Now findd the scale factor.
If given two shapes and need to find the scale factor, We must know which one was the original and which one is the image or the new shape. Then we need to know the length of corresponding sides and set them up in a ratio
Answer:Scale factor = 1/2
The purple shape is a dilation of the black shape.
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
Now findd the scale factor.
If given two shapes and need to find the scale factor, We must know which one was the original and which one is the image or the new shape. Then we need to know the length of corresponding sides and set them up in a ratio like so: Scale Factor = purple/black
Scale factor = 10/20 = 1/2

Oh and pls explain how
Answer:
1) 1/2
2) 3
3)-5
Step-by-step explanation:
to find slope: divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. so here on 1) you do (3-2)/(2-0)= 1/2.
2) (7-1)/(-1- (-3))= 6/2=3.
3) (-15-0)/(7-4)= -15/3=-5
what is a equivalent expression for 4(x-2)
The coordinates of the vertices of △XYZ are X(−5, 5), Y(−3, −2), and Z(4, 0). The slope of XZ is __, the slope of YZ is __, and the slope of XY is __. △XYZ __ a right triangle because ____________.
-7/2 -5/9 -2/7 2/7 9/5 is is not no two of these slopes have a product of -1 two of these problems have a product of -1
Answer:
Slope of XZ = -5/9
Slope of YZ = 2/7
Slope of XY = -7/2
Step-by-step explanation:
Slope is expressed as;
m = y2-y1/x2-x1
For XZ
X(−5, 5), and Z(4, 0)
Slope of XZ = 0-5/4-(-5)
Slope of XZ = -5/4+5
Slope of XZ = -5/9
For YZ
Y(−3, −2), and Z(4, 0).
Slope of YZ = 0-(-2)/4-(-3)
Slope of YZ = 2/4+3
Slope of YZ = 2/7
For XY
X(−5, 5), Y(−3, −2)
Slope of XY = -2-5/-3-(-5)
Slope of XY = -7/-3+5
Slope of XY = -7/2
For two lines to be perpendicular, the product of their slope must be -1
Taking the product of XY and YZ
mXY * mYZ = -7/2 * 2/7
mXY * mYZ = -1
since the product of mXY and mYZ is -1. this shows that line XY is perpendicular to YZ and showing that the triangle XYZ is right triangle
what is the slope of line parallel to line y=3x+2?
Answer:
3
Step-by-step explanation:
The slope is 3 because when two lines are parallel, they have the same slope.
Answer:
Two lines that are parallel have the same slope. So in this case, the slope to the function parallel to f(x)= 3x+2 is equal to 3

Answer:
x = 12
Step-by-step explanation:
Reference angle = 45°
Opposite side length = x
Hypotenuse = 12√2
Thus, to find x, apply trigonometric ratio.
[tex] sin(45) = \frac{x}{12\sqrt{2}} [/tex]
Multiply both sides by 12√2
[tex] sin(45)*{12\sqrt{2}} = x [/tex]
[tex] \frac{1}{\sqrt{2}}*{12\sqrt{2}} = x [/tex] (sin 45 = 1/√2)
[tex] \frac{1*12\sqrt{2}}{\sqrt{2}} = x [/tex]
[tex] \frac{12\sqrt{2}}{\sqrt{2}} = x [/tex]
12 = x
x = 12
3x-4=23 solve the equation
Answer:
9
Step-by-step explanation:
first add 4
3x=27
divide 3
x=9
Answer:
= 9
Step-by-step explanation:
3 − 4 = 2 3
Add 4 to both sides of the equation:
3 − 4 + 4 = 2 3 + 4
Simplify:
3=27
Divide both sides of the equation by the same term:
3/3=27/3
Cancel terms that are in both the numerator and denominator:
=27/3
Divide the numbers:
x=9
Done!
