Answer:
y=-3x+1
Step-by-step explanation:
plug in point into x and y, replace -4 as a +b(or any other variable to represent y intercept)
therefore,
7=-3(-2)+b
7=6+b
1=b
y=-3x+1
Answer:
There are 30 students in the class
Step-by-step explanation:
we can write a ratio as:
8:10 as 24:x
Writing this as an equation gives:

Answer:

Step-by-step explanation:
Let
represent the number of hours Gary must work per week.
The contract states that Garry must work more than 20 hours.
This can be represented algebraically by the inequality;

Hello :
4 - 2/5 = 20/5 -2/5 =18/5 =(<span>√(18/5))²</span>
The equation of the line through (-4, -5) parallel to 3x-4y=-8 can be written as
3(x-(-4)) - 4(y-(-5)) = 0
3x -4y - 8 = 0
3x - 4y = 8
