Answer:
f(3) = -11
Step-by-step explanation:
f(x) = -3x-2
let x=3 and replace it in the above equation
f(3) = -3(3) -2
f(3) = -9 -2
f(3) = -11
Answer:
462 ways
Step-by-step explanation:
The formula to use in solving this problem is given as the Combination formula
The Combination formula is given as
C(n , r) = nCr = n!/r! (n - r)!
We are told that a food bakery has 12 pies unsold at the end of the day which they intend to share to 6 food banks
n = 12, r = 6
In order to ensure that at least 1 food bank gets 1 pie, we have:
n - 1 = 12 - 1 = 11
r - 1 = 6 - 1 = 5
Hence,
C(11, 5) = 11C5
= 11!/ 5! ×(11 - 5)!
= 11!/5! × 6!
= (11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)/ (5 × 4 × 3 × 2 × 1) ×( 6 × 5 × 4 × 3 × 2 × 1)
= 462 ways
Answer:
B. Start at -7 on the number line and move 11 to the right.
Step-by-step explanation:
<u>Given:</u>
We can add or remove only positive numbers on the number line to get it correct, so we need to open the parenthesis. When evaluated we get:
-7- (-11) = - 7 + 11 = 4
<u>Correct interpretation of of this expression is:</u>
- Start at -7 and add 11, thus move 11 points to the right, to get 4 as final point.
<u>Correct choice is:</u>
- B. Start at -7 on the number line and move 11 to the right.
In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.
