Answer:
B.2
Step-by-step explanation:
To make ΔA'B'C' from ΔABC, we need to use t
he scale factor =|A'B'|/|AB|=10/5=2
H(x) equals what? I think you've missed that detail. :)
Answer:
a) none
b) vertical through the middle
c) horizontal through the middle
d) none
Step-by-step explanation:
a) A repeated asymmetrical pattern rarely has a line of symmetry. (I can't think of a case where it does.)
__
b) This figure has left-right symmetry about its centerline. (In general, a light bulb will not, because the screw threads are asymmetrical.)
__
c) Each of the letters is symmetrical about its horizontal centerline, so the word is as well.
__
d) The letter S is symmetrical about its center point, but not about any horizontal or vertical line. This word is not symmetrical about any line.
__
Answer:
x= -3/16
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
y=-9
Step-by-step explanation:
If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22
We can solve for multiplication first:
4-2y=22
Then we can subtract four on both sides, canceling out the four on the left side:
-2y=18
Now to isolate y, we divide both sides by -2, resulting in the solution:
y=-9
Hope this helps!
