Answer:
a. x = 7c
b. $28
Step-by-step explanation:
Her allowance starts at $20.
Out of 5 chores, for each chore she completes, she receives $3.
For each chore that she does not complete, she loses $4.
a. An expression describing her allowance
Let her total allowance be x:
x = 20 + (3 * c) + (-4 * (5 - c))
x = 20 + 3c - 20 + 4c
x = 20 - 20 + 7c
x = 7c
b. If she completes 4 chores, she will receive:
x = 7 * 4 = $28
Answer:
answer) 7/6
Step-by-step explanation:
10x- 15 = 4x-8
10x- 4x= -8+15
6x= 7
x= 7/6

Answer:
617.902
Step-by-step explanation:
(6 * 100) + (1 * 10) + (7 * 1) + (9 *1/10) + (2 *1/1000)=308951/500
308951/500=617.902
Answer:
The one that gives us the fastest y-intercept is "b". The coordinates are (0,15).
Step-by-step explanation:
In order to check which form gives us the fastest y-intercept value, let's apply x = 0 in all three of them and check how many operations we need to do to get our desired results.
a) f(x) = -3*(x - 2)² + 27
f(0) = -3*(0 - 2)² + 27
f(0) = -3*(4) + 27
f(0) = -12 + 27
f(0) = 15
b) f(x) = -3*x² + 12*x + 15
f(0) = -3*(0)² + 12*(0) + 15
f(0) = 15
c) f(x) = -3*(x + 1)*(x - 5)
f(0) = -3*(0+1)*(0-5)
f(0) = -3*(-5)
f(0) = 15
The fastest one is "b". Since it is in the standard second degree equation form "a*x² + b*x + c", we could have checked immediately by the value of "c".
The y-interecept is (0,15).
