Answer:
8b*5b
Step-by-step explanation:
Any number raised to power of 0 is 1.
In (-4x)^0, because of the parenthesis, the whole number is being raided to 0, which gives 1.
But in -4x^0, only x is being raised to 0, thus -4x^0 = -4(1) = -4.
Step-by-step explanation:
-5y=35
=35÷(-5)
= -7
=-5×-7
=35
Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is
.
Now we need to find the radius of the given circle
.
To find that let's compare with the formula of the circle with is
, where r is the radius.
We get 
take square root of both sides.

Hence radius of the given circle is r = 2.
The equation of the line passing through
and
is
. Here
is the slope of the line.
Substituting numerical values, the equation of the line is

The equation of the line is
