Step-by-step explanation:
a^2 + 2(b - 6) - 17. a = -7 b = 2
= (-7)^2 - 2(2 - 6) - 17
= 49 - 4 + 12 - 17
= 40
Answer:
Domain : all real numbers
Range: All numbers greater than 2
Step-by-step explanation:
The shark. (Haha, I'm sorry.)
There are no restrictions on the x. X can be any real number.
The range, however, does have restrictions. The range has to be a number greater than 0.
Why?
Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.
There are 16 ounces in 1 pound: 5*16=80
80 ounces divided by 8 ounces gives you 10 8 ounce servings
75% of x = 63
<span>75/100 * x = 63 </span>
<span>So dividing by 75 / 100 on both sides </span>
<span>x = 63 / 75 / 100 </span>
<span>x = 63*100/75 </span>
<span>x = 84 </span>
<span>The number is 84 </span>
<span>So 75% of 84 = 63! </span>
<span>Hope that helps!</span>
