Answer:
The answer is "2x-y=4"
Step-by-step explanation:
Given:
The Formula of Slope:
by replacing the (2,0) and (0,-4) coordinates in the above formula:
if point y intercepting in x then x=0, for this the value of x= 0 and c=-4.
Equation of the line:
apply m and c value in the above equation:
Subtract by 2x on both sides of the equation we get:
<h2>Answer:</h2>
or
4 to the 21st over 5 to the 6th.
<h2>Step-by-step explanation:</h2>First, we need to write our expression. Let's do it step by step:
<u>4 to the 7th:</u>
<u>5 squared:</u>
<u>4 to the 7th over 5 squared:</u>
<u>4 to the 7th over 5 squared all raised to the 3rd power:</u>
<u></u>
Using the law of exponents:
Finally, the answer is 4 to the 21st over 5 to the 6th.
Answer:
not factorable
Step-by-step explanation:
The easiest way to factor is to find two numbers of the "a" value (the coefficient before ) and the factors of the c value (10) that ADD up to give you -9, in this case it would be:
1 -10 --> 1(-10) gives you -10
1 -1 --> 1(-1) gives you -1
adding these together -10 + (-1) = -11 which does not equal -9.
You could stop here and conclude that this is not factorable by inspection.
Another method: using the quadratic formula to find its roots.
