<u>Answer</u>
A. c = 4
<u>Explanation</u>
In algebra, what you do to one side of the equation, the same has to be done on the other side.
32c = 128
divide both sides by 32
32c = 128.
32c ÷ 32 = 128 ÷ 32
c = 128/32
= 4
2 - 8y + 7y = 4
-1y = 2
y = -2
y = -2
When you divide exponents, you just subtract them. the answer to this equation is a^2 (a squared). This is because 8-6 = 2. Conversely, if you were multiplying two terms with exponents you would add the exponents together. For example: a^3 * a^2 = a^5, because 3 + 2 = 5
Step-by-step explanation:
For all y values, just look along the y-axis. The same applies to the x-axis.
