Answer:
A. y + 1 = -2(x – 5)
Step-by-step explanation:
For a line with slope m through point (h, k), the equation is ...
y -k = m(x -h)
Fill in your values of m=-2, h=5, k=-1 and you have ...
y -(-1) = -2(x -5)
y +1 = -2(x -5) . . . . . . simplify. Matches selection A.
Answer:
lacy = 8 jack= 24
Step-by-step explanation:
let x be lacys age
3x - 3 + x-3 = 14
3x+x -3 = 14 + 3 = 17
4x = 17 +3 = 20
x = 20/4 = 5
lacys age now = 5+3 = 8
jacks age now = 8 * 3 = 24

Step-by-step explanation:
Solving (a):
First, we categorize each data (to get their frequencies):
PI PI PI PI PI PI PI PI PI ---> Frequency: 9
S S S S S S S S---> Frequency: 8
V V V V V V V V V V V V V ---> Frequency: 13
PO PO PO---> Frequency: 3
B ---> Frequency: 1
C C ---> Frequency: 2
Total = 36.
The frequency table is as follows:
Solving (b): The relative frequency and percentage.
Relative frequency is calculated by dividing each frequency by the total frequency.
So, we have:
The percentage is calculated by multiplying the frequency by 100%.
So, we have:
Solving (c): Percentage that mentioned vegetables and fruits, poultry, or cheese?.
This is calculated as:
