Answer: 1760000
Step-by-step explanation:
Answer:Y=14
Step-by-step explanation:
Simplify
2nd one divide both sides by 5
5x+4y=4
hmm, seems familliar
times it by -1
-5x-4y=-4
same as other one
they are the same line
therefor the solution set is all the points on the line -5x-4y=-4 or y=(-5/4)x+1
solution set is alll points on y=(-5/4)x+1 or 5x+4y=4
<h3>
Answer: k = 6+10x</h3>
=======================================================
Work Shown:
The result is in the form 
with k = 6+10x
------------------------
Explanation:
First we need to get everything as an exponential expression with a base 2.
We rewrite 64 as 
and 4 as 
in the second step.
In the third step, I used the rule 
which says to multiply the exponents together. That's how I went from 
to 
. Then the 2*5x in the exponent becomes 10x.
To wrap things up, I used the rule 
which says to add the exponents when we multiply stuff of the same base together.
