Step-by-step explanation:
y =
Find two points
When x = 0 , y = 0 + 2 = 2
D(0 , 2)
When x = 5;
E(5, 3)
Plot (0, 2 ) and (5 , 3) in the graph and join the points. This will be the line for the equation y =(1/5)x + 2
y = -x + 8
When x =4 , y = -4 + 8 = 4
A(4 , 4)
When x = 6 ; y = -6 + 8 = 2
B(6 , 2)
Plot (4,4) and (6, 2) in the graph and join the points. This will be the line for the equation y = - x + 8.
This lines will intersect at point (5,3) and that point will be the solution of the equation.
Answer:
y = 130(24/13)^(x -10)
Step-by-step explanation:
The y-value changes by a factor of 240/130 = 24/13 for a unit change in the x-value. This means we can write the function as though it had an initial value of 130 and a growth factor of 24/13, translated 10 units to the right.
y = 130(24/13)^(x -10)
_____
<em>Additional comment</em>
This can also be written in the form ...
y = a·e^(kx)
where a=130·(24/13)^(-10) ≈ 0.28266, and k=ln(24/13) ≈ 0.61310
The sequence of transformations used to obtain figure A'B'C'D'from figure ABCD are a reflection across the y-axis followed by a horizontal translation 1 unit right
<h3>Complete question</h3>Figure ABCD is transformed to figure A'B'C'D', as shown below: (see attachment)
Which of the following sequences of transformations is used to obtain figure A'B'C'D'from figure ABCD?
<h3>How to determine the transformation?</h3>From the attached figure, we can see that:
ABCD and A'B'C'D' are on either sides of the y-axis.
This means that ABCD is first reflected across the y-axis.
ABCD is 2 units from the y-axis, while A'B'C'D' is 1 unit from the y-axis.
This means that the reflection is followed by a translation.
The unit of translation is:
Unit = 2 - 1
Evaluate
Unit = 1
1 represents a right translation
Hence, the sequence of transformations are a reflection across the y-axis followed by a horizontal translation 1 unit right
