Since Carmen gives two coins to Frankie for every five that she gets, she effectively only gains 3 coins at a time. Therefore, if she has 9 coins, Frankie must have 6.
For find f(-2) of f(x)=7x+3, plug in -2 for x.
7(-2)+3=y
-14+3=y
y=-11
To find the rate, or the slope, you divide x/y. So 2/6 is 1/3. 3 over 9 is also 1/3. So the rate is 1/3. In rates you always divide, you don't mulitply or subtract or add to find the rate.
Answer:
x^9/8
Step-by-step explanation:
The exponent property that you can use here is that when multiplying the two exponents, you add their exponents
Thus, (x^7/8) (x^1/4) = x^(7/8+1/4)=x^9/8
