Answer:
(a) 0.7
(b) 4.9
Step-by-step explanation:
If z is a linear function of x and y and the slopes in the x and y directions are 3 and 2, respectively, z can be written as:
Where 'c' is a constant value.
(a) A change of 0.2 in x and 0.1 in y produces the following change in z:
(b) Applying the point x=7, y=4, z=5 to the general equation gives us the value of 'c':
For x=7.1 and y=3.8, the value of z is:

<u>Answer:</u>
3/4
<u>Step-by-step explanation:</u>
We are to find the scale factor of the dilation that maps the pre-image of triangle ABC with vertices A(−5, −4), B(−7, 3) and C(3, −2) to the image triangle A'B'C' with vertices A' (−3.75, −3), B' (−5.25, 2.25) and C' (2.25, −1.5).
Center of dilation is at the origin.
To find the scale factor, we will divide the corresponding vertices of the image and pre-image.
A(−5, −4) ---> A' (−3.75, −3) =
B(−7, 3) ---> B' (−5.25, 2.25) =
C(3, −2) ---> C' (2.25, −1.5) =
Therefore, the scale factor of the dilation is 3/4.
