Answer:
Step-by-step explanation:
To find out the m(slope) of the equation use the formula:
.
Substitute the values:
Combine the values:
Find the value of the fraction:
M is -3.
The equation so far is 
To find the y intercept, substitute one pair of coordinates into the equation and solve for b:
.
We see that b =-17 so the full equation would be:
.
Answer:

Answer:
first find the common factors of 18,26 and 72.
18: 1,2,3,6,9,18
26: 1,2,13,26
72: 1,2,3,4,6,8,12,18,24,36,72
next, find the common factors which can divide all numbers: 2
then find the highest factor which can divide all numbers. in this case, we only have one factor which is 2 and that shall be the H.C.F.
Answer:
D
Step-by-step explanation:
Answer:
Given expression is equal to 1/32
Step-by-step explanation:
Given that:
= 4^(-5/2)
To eliminate "-" sign we will invert the fraction as follows:
= (1/4)^ 5/2
Or it can be written as:
= 
This is the simplified expression.
