The answer would be 9/18 because neither 4 or 8 can divide equally into those 2 numbers.
X/6 + 4 = 15
First, subtract 4 to both sides:
x/6 = 11
Now multiply 6 to both sides:
x = 66
Easy! First just subtract it like you would! Then, when you get to the 4 tens of the number, explain how you subtracted that!
Remember:
a) (x,y) => (x, -y) is a reflection across X axis
b) (x,y) => (-x,y) is a reflection across Y axis
Here △RST is mapped to △R′S′T′ using the rule (x,y)→(x,−y)
Hence it is a reflection across X axis.
The size of the triangle does not alter.
But when this is followed by (x,y)→(3x,3y), the lengths increase by a factor 3.
Hence the triangles do not remain congruent.
△RST is not congruent to △R′S′T′ because the rules do not represent a sequence of rigid motions.
Option A) is the right answer
Answer:
y=1/3x-5
Step-by-step explanation:
y=1/3x+b
0=1/3(15)b
0= 5+b
b=-5
Hope this helps!
