Answer: x= 25
Step-by-step explanation:
28+47+ y(some number)= 180
solve for y to get 75 and since 75=3x x=25
The correct answer is: (4,1)
Explanation:
First let me explain you what a vertex is (in non-bookish terms).
(In simple words) Vertex is a (common) <em>point</em> where<em> two rays or line segments meet</em>. This definition holds when we talk about straight lines (while looking at the graph). In the graph of absolute valued function attached with the question, you can see there are two lines, one going up (increasing) and the other going down (decreasing), and both <em>meet</em> at <em>x = 4</em>. Now look at the value of <em>y</em> at <em>x = 4</em>. It is +1. In other words, you can say that at x = 4, there is a transition in a graph.
Therefore, the vertex of the absolute value function is (4, 1).
Information: The definition of vertex totally changes when we talk about parabola, or any non-linear equation. In that case, the vertex is the peak value of the graph (where there is a transition). The peak could be positive or negative depending upon the graph or equation; however, in the case of straight lines, adhere to what I explained above. Goodluck!
-i
Answer:
6.9 minutes
Step-by-step explanation:
Setup equality:
Cross multiply:
12.3m = 85
Divide both sides of equality by 12.3:
m = 6.9 minutes
Short answer: No afraid not.
Opposite sides of a parallelogram must be equal and parallel. The opposite sides of a kit are neither. To make sure you understand, measure the upper left side and the lower right side. The upper left is shorter than the lower right (even though these sides are opposite one another).
It you extend the upper left line upward and do the same thing to the lower right, you will get two lines that meet. No parallelogram will do that.
Answer:
(- 3, 7 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
Here (x₁, y₁ ) = (0, 11) and (x₂, y₂ ) = (- 6, 3) , then
midpoint = ( , ) = ( , ) = (- 3, 7 )
