For -(4)^7
the - is not affected by the power of 7
For (-4)to the power of7 is the same as -4 to the power of 7
It is because 7 is an odd number,the - will not change .Therefore
(-4)^7= -(4)^7
But keep in mind that if the power is an even number , the - will change to + when the situation is (-4)
For example,(-4)^4=(4)^4

Answer:
y intercept is 18
Step-by-step explanation:
It is given that
Monthly rent for phone service = $18
charges for each long distance minute = $ 0.07
Let us assume number of minutes used = x
also let us represent total cost by y
So the total cost = ( charges per minute )(number of minutes) + monthly rent

now we compare this equation with y=mx+b
where m is the slope and b is y intercept
so we have b= 18
hence y intercept is 18
