Reflecting across the Y axis, the y value stays the same and the X value become opposite:
(-4,6) would become (4,6)
Now reflecting across the X axis the x value remains the same and the Y value becomes the opposite:

How do I solve this step by step?
Answers
Answer:
larger #=32
smaller #= 26
Step-by-step explanation:
We can solve this by using x for the larger number.
larger #= x
smaller #= x-6
x+x-6=58
2x-6=58
2x=64
x=32
The larger number is 32. To find the smaller # you simply substitute the variable x-6 which is now 32-6 which is 26.
Hope this helps!
Answer:
smaller number = 26
larger number = 32
Step-by-step explanation:
x = smaller number
y= larger number =x+6
so
x+y=58
x+6+x= 2x+6=x58
2x=58-6=52
x=522= 26
y=x+6=26+6 = 32
checking
x+y=58
26+32= 58

Which equation represents exponential growth?
O A) y= 2x
O B) y = 3(5)
OC) y = 4x?
OD) y = 2(0.5)
Answers
Answer:
C) y = 4x?
Step-by-step explanation:
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change of a quantity with respect to time is proportional to the quantity itself.
There are two types of exponential functions: exponential growth and exponential decay. In the function f (x) = bx when b > 1, the function represents exponential growth. In the function f (x) = bx when 0 < b < 1, the function represents exponential decay
Why does a fraction with lesser denominator have larger pieces than the fraction with a greater denominator
Answers
Answer:
Step-by-step explanation:
The bigger the denominator the smaller the fraction.
For example if you have 1/9 and 1/5.
The fraction 1/5 has a greater denominator and is greater than 1/9, because it is split into less parts.
Hope this helped :)
e.g. 1/6 47/82
for 1/6 the shape will be split into 6 parts
