Answer:
y = -5/3x - 3
Assuming this is a linear function
Step-by-step explanation:
1. Use (y2-y1)/(x2-x1) to find the slope of the equation, assuming it is a linear function.
(-3-2)/(0+3) = -5/3 <--- slope
2. The y-intercept is going to be the (0, -3) point, since the point is directly on the y-axis.
3. Put both of those values into the new equation
y = -5/3x - 3
Answer: You take the 2 middle columns in this case the purple gray looking one and the brown one and add them together divide them by 2
Step-by-step explanation:
Answer:
it may multiple by 10 times
For #1. Step 1: Set the equations equal to one another: (3x + 20) = (2x + 40)
Step 2: Subtract 2x on both sides of the equal sign: (3x-2x + 20) = (2x-2x + 40)
x + 20=40
Step 3: Subtract 20 on both sides of the equal sign: x + 20-20= 40-20
x=20
Step 4: plug in 20 for x: 3(20) + 20= 80 & 2(20) + 40= 80
