Answer:
7.9
Step-by-step explanation:
the first thing to do is find the second projection.
16-7 = 9
than we can use a proportion to find BD
7 : BD = BD : 9
BD = √9 x 7 = √63 = 7.9
we have to use the square root because in the proportion BD Is repeated two times. If we don’t use it, we find BD^2
Answer:
There are an infinite number of solutions.
Step-by-step explanation:
An equation with 2 unknowns give an infinite amount of solutions, here is just one of the many:
Let y= 3 ( y can be any number)
(3) + 1 = -4x
4 = -4x
x = -4/4
x= -1
(x;y) = (-1;3)
Generally x and y can be any number, just let x or y be any number, then find the other variable based on the value of the number u assumed.
Answer:
B1= -7
B2=-9
400 times bigger
Step-by-step explanation:
Answer: D
Explanation: I am not completely sure but the angles would be the same because they are right next to eachother
Hope this helps ;)
The graph that shows f(c)=0.5|x+3|-2 has been added in the attachment.
<h3>How to solve for the graph</h3>
We are given the equation to be f(x) = 0.5|x + 3| – 2
This equation above is an absolute value equation that was entered into a graphing calculator
The absolute value equation is represented by the values
f(x) = a|x - h| + k
in the equation above, h and k are the vertex of the graph
when we compare the absolute value equation with the equation we have in the question, we would have h = +3 and k = -2
Hence we would say that the vertex is 3 , -2.
When the graph was plotted, the vertex is the point that shows that meeting at a point in the point 3, - 2 are shown as the vertex also
