Answer:3009/4
Step-by-step explanation:
Or 752.75
Answer:
2x+3
Step-by-step explanation:
Since her brother is m years old, you would have to multiply her brother's age by 2 since the question says "...twice here brother's age." This part would equal to the equation 2x. The question also says " ...3 years more..." This would change the equation with the addtion of 3. The completed problem would then be 2x+3. Hope this helped!
Answer:
1.
m= 
b= 2
2.

m= 
b= 1
3.

m= 3
b=4
Step-by-step explanation:
1. The line intersects the y-axis at the point (0,2) therefore its y-intercept is b=2.
The line rises up 1 unit on the y-axis for every 4 units on the x-axis therefore the line has a slope of m=1/4.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that
2. The line intersects the y-axis at the point (0,1) therefore its y-intercept is b=1.
The line down up 1 unit on the y-axis for every 3 units on the x-axis therefore the line has a slope of m= -1/3.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that 
3. The line intersects the y-axis at the point (0,4) therefore its y-intercept is b=4.
