Reflecting a function across the x-axis means to change the sign of the function itself: you're mapping 
So, if you have a x/y values table, you simply have to change sign to all the values in the y column.
Answer:
3/40
Step-by-step explanation:
Multiply 1/5 * 3/8
When the dilation is centered on the origin, you can multiply each of the individual coordinates by the scale factor.
All the coordinates are ±5 and the scale factor is 1/5. Multiplying those gives ±1. The only selection with all coordinates being ±1 is
.. Selection A.
You can check to see if the signs agree in detail. (They do.)
The correct expression is A
16.75 square yards because area of a triangle is half the base times the height. 40.2÷4.8 is 8.375. Since that is half the base, multiply by two. 8.375×2 is 16.75. Hope that helps! :D
