Answer:
Check the explanation
Step-by-step explanation:
Y = 11.5 + 4.5*X1 -2.5*X2 +0.7*X3+1.6*X4 -2.4*X5 -2.8*X6
FOR JANE
X1 =1 , X2 =1 , X3 =5 , X4 =0 ,X5=0, X6=1
SO,
Y =11.5+(4.5*1)-(2.5*1)+(0.7*5)+0+0-(2.8*1)
= 14.2
..........................
FOR Sophie
X1 =1 , X2 =1 , X3 =10 , X4 =1 ,X5=0, X6=0
so,
Y =11.5+(4.5*1)-(2.5*1)+(0.7*10)+ (1.6*1)+0+0
= 22.1
Answer:
Subtract 8.5
Step-by-step explanation:
To solve the equation, y has to be isolated (only y will be on one side of the equation)
To do this, we have to get rid of the 8.5, so it has to be subtracted from both sides.
So, the correct answer is subtract 8.5
For this case we have that the point-slope equation of a line is given by:

Where:
m: It is the slope of the line
It is a point through which the line passes
In this case we have to:

Substituting in the equation we have:

Answer:

We just need to replace the value of the slope
Answer:
(-3, -4)
Step-by-step explanation:
f(x) = x – 1 and g(x) = –x – 7
f(x) = g(x)
- x-1= -x-7
- 2x= -6
- x= -3
- f,g= -4
