Answer:
no 2³ = 8
Step-by-step explanation:
2³ = 2 times 2 times 2 which = 8
Y varies inversly as x, so:
<span>y = k/x, where k is the constant of proportionality, so: </span>
<span>4.5 = k/3.25, so </span>
<span>k = 4.5 x 3.25, so </span>
<span>k = 14.625, and </span>
<span>y = 14.625/x </span>
<span>when y = 3.75, </span>
<span>3.75 = 14.625/x, so </span>
<span>x = 14.625/3.75, so </span>
<span>x = 3.9
Answer:
B. 3.9</span>
First we subtract 4 from both sides to get the right side equal to 0. x^2-12x+32. then we need to find two numbers that multiply to 36 and add to -12. we know that the numbers need to be negative because they add to a negative number. also if only one was negative, then the product won't be positive. the two numbers are -8 and -4. (x-4)(x-8). x then equals 4 and 8.
