Answer:-7^2(negitive seven to the second power)
Step-by-step explanation:
Answer:
y=3x
Step-by-step explanation:
A proportional situation is a situation the crosses through the origin or (0,0). This means its starting value for y-intercept value is 0. It has the form y=mx for this reason. The solution is y=3x.
Expanded form is when you just write it out.
so 9 cubed becomes:
9×9×9
and 20 squared becomes:
20×20
the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.
