Answer:
f(-2) = -1
Step-by-step explanation:
f(x) = -x^2 + 3
f(-2) means when x is -2
Shown in the graph below, the point of solution is: (-2,-1), so when x is -2 y is -1
Answer:
order of
Step-by-step explanation:
$138.78 is the rounded figure
Answer:
1. The equation to solve this equations is:
= 3x = 231
2. The three integers are 77, 78 and 79.
Step-by-step explanation:
The sum of 3 consecutive integers = 234
let x = first integer
let x+1 = second integer
let x+2 = third integer
Therefore,
= x + x + 1 + x + 2 = 234
simplified to:
= 3x = 231
b) Adding three consecutive numbers adds the smaller number to itself three times, and then adding 1 for the second number, and two for the third number. So, the sum of the three consecutive numbers is divisible by 3. Therefore, to get the second (or middle) number, divide the total by 3, and then subtract 1 and add 2 to get the first and the third numbers, respectively.
