Point D (?)
A. (5,4)
B. (5,2)
C. (5,3)
D. (3,0)
Answer:
(5,3)
Step-by-step explanation:
I took the test and go it right!
The coordinate point for D is (5, 3). Therefore, option C is the correct answer.
What is a rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.
Given that, Point A (2,2), Point B (3,4) and Point C (4,1)
The coordinate point for D that would make ABDC a rhombus.
So, the coordinate point for D is (5, 3).
Therefore, option C is the correct answer.

Answer:
60
Step-by-step explanation:
The whole thing is 180 so if you subtract 180 from 120 you get 60.
Answer:
60 degrees since a straight line is 180 degrees
Step-by-step explanation:
Since part of it is 120 degrees the other part must be 60 because 120 + 60 = 180

Someone explain to me how to write an equation out in slope-intercept form in simple terms with examples I'm so confused
Answer:
are you talking about y=mx+b? M would be the slope, and B would be the y intercept, so if we wanted to do, lets say 4,5, we would say y=4x+5, i think,
Step-by-step explanation:
An equation in slope-intercept form looks like this: y = mx+b
In the equation, m is equal to the growth rate of the line on the graph and b represents the y-intercept (where the line meets with the y-axis).
For the line shown in the picture below, the equation is y = 1x + 2 (not exactly but based on estimates). Also, you can ignore the writing on the picture. (0-0')
y = 1x + 2
In this equation. 1 represents the growth rate and 2 represents the y-intercept.
So, when writing an equation, look for these two things:
y-intercept: where the line of a graph meets with the y-axis
growth rate: how much is the line increasing by on the y-axis for every unit on the x-axis?

what does x equal in this equation -5x + 8 = -2
Answer:
x = 2
Step-by-step explanation:
-5x + 8 = -2
-5x + 8 - 8 = -2 -8
-5x = -10
-5x/5 = -10/5
-x = -2
x=2
Simplify the equation:
-5x = 2 + 8
-5x = 10
x = -2

A triangle has side lengths of (2u-4v)(2u−4v) centimeters, (10u+2w)(10u+2w) centimeters, and (w-7v)(w−7v) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
3w−11v+12u
Step-by-step explanation:
2u−4v+10u+2w+w−7v
2u-4v+10u+2w+1w-7v
2u−4v+10u+2w+1w−7v
2u+10u−4v−7v+2w+1w
2u+10u −4v−7v +2w+1w
^12u ^-11v ^3w
12u -11v+3w
3w−11v+12u
The perimeter of the triangle is represented by the expression 3w−11v+12u.
What is the perimeter of the triangle?Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees. The perimeter of the triangle is defined as the sum of all the sides of the triangle.
Given that a triangle has side lengths of (2u-4v)(2u−4v) centimeters, (10u+2w)(10u+2w) centimeters, and (w-7v)(w−7v) centimeters. The perimeter of the triangle is calculated by adding all the sides of the triangle.
E = 2u−4v+10u+2w+w−7v
E = 2u-4v+10u+2w+1w-7v
E = 2u−4v+10u+2w+1w−7v
E = 2u+10u−4v−7v+2w+1w
E = 2u+10u −4v−7v +2w+1w
E = 12u -11v+3w
E = 3w−11v+12u
Therefore, the perimeter of the triangle is represented by the expression 3w−11v+12u.

The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so
cost = price + 0.1*price
cost = 1.1 * price
price = cost / 1.1
price = 22 / 1.1 = 20
now we need 20% of that so that's
20 * 0.2 = 4
If she's simple-minded enough to tip that would amount to $4

What is the value of x of the acute angles of a right triangle measure 8x and 12x?
A.2
B. 4.5
C. 7
D. 9.5
Answer:
B. 4.5
Step-by-step explanation:
The sum of all interior angles of a triangle is 180 degrees
Since we know it is a right triangle, there is one angle that is 90 degrees
The acute angles are given as 8x and 12x
Add them up and isolate x to find the value of it
8x + 12x + 90 = 180 1. Add like terms
20x + 90 = 180 2. Subtract by 90 on both sides
20x = 90 3. Divide by 20 on both sides
x = 4.5
