Reflectional symmetry<span> exists when the figure can be folded over onto itself along a line. This line is called the "line of symmetry". The correct answers for this would be.
</span>-A line of symmetry will connect a vertex and a midpoint of an opposite side
-it has 7-fold symmetry.
Answer:
Im sorry im not sure how to do this either lol :/
Step-by-step explanation:
The unit rate means we need to find it per one soda can. So, 32/32 is one. We do the same to $3.99. $3.99/32 is about 13 cents.
Unit rate is: 13 cents per soda can
Answer:
a) 
b)
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.
Point slope:
a) 
in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is 
.
We will substitute and 
.
This simplifies to:
b) The equation y=3x+4 follows y=mx+b. For the perpendicular line, 
. We will need to change it into its negative reciprocal which is 
.
We will substitute and 
.
