Answer:
im gonna guess that the problem is 2x+13-9y, the answer is 38
Y=-4x+28
y=-4x+25
y=-3x-12
y=-3x-5
y=-4x-12
y=-4x-4
y=mx+b
m=slope
b= y intercept
C is the answer
Answer:
1. y=3/2x + 12 2. y= 1/4x + 8
Step-by-step explanation:
Use the slope formula to get the slope for each line. Then plug either of the x and y coordinates into the formula y= mx + b and also plug in the slope that you just found and solve for b.
Answer:
0.36
Step-by-step explanation:
Given that:
Mean = 70
Standard deviation = 5.5
score (x) = 72
Formular for obtaining Standardized score (Zscore) :
Zscore = [score (x) - mean] / standard deviation
Hence,
Zscore = (72 - 70) / 5.5
Zscore = 2/ 5.5
= 0.3636363
Zscore = 0.36 ( 2 decimal place)
