Answer:
Reflection across the Y axis
Step-by-step explanation:
If you plot each point of the triangle in its before and after positions you are able to see that the triangle's original shape was reflected across the Y axis to reach its end form.
Think about a rubik's cube rolling if you are struggling with reflections.
Answer:
The value of k=4
Step-by-step explanation:
we have
f(x)=0.4x
This function represent a linear direct variation (The line passes through the origin)
we know that
If f(x) is shifting up by 4 units
then
The y-intercept of the function will be the point (0,4)
therefore
The function g(x) will be -----> g(x)=0.4x+4 (equation of the line into slope
intercept form)
The rule of the translation
f(x) --------> g(x)
(x,y) -------> (x,y+4)
The translation is 4 units up
therefore
The value of k=4
27+7 = 34
so, the answer is 34
Answer: Katie's Sample
Step-by-step explanation: People usually skateboard in the summer not the winter
28 = 3x+4x
x = 4
3x = 12
4x = 16
12:16 = 3:4
