First solve for x in the first equation. So you'll have to substitute,
5(3x-7)=20
15x-35=20
Then add 35 to both sides.
15x=55
Divide 55 by 15.
So x = 3.66...
Then plug in 3.7 for x in 6x-8
6(3.7)-8
Its approximately 14.2
Answer:
You could use a graphing calculator to see the lowest point in the graph OR you could put that equation into it's completed squared form, which is (x-4)^2 -4. The opposite of -4 in the parentheses is positive 4, and the leftover -4 is the y value. So that also becomes (4,-4)
Answer: 
Step-by-step explanation:
For this exercise it is important to remember the following:
1. By definition, the "Product" is the result of a multiplication.
2. The "Difference" is defined as the result of a subtraction.
3. The Distributive property states that:
Keeping the above on mind, you know that:
"The difference of 
and 
" can be represented with the following expression:
Therefore, "The product of -13 and the difference of and " can be represented with this expression:
Finally, you must apply the Distributive property in order to simplify the expression. You get:
Well the first problem that i solve is you have to move 12 it will give you
-3y power 12 - 3y + 12
