Pls help. Can’t do this.
Anna [14]

Step-by-step explanation:

The equation of line A:

y-1=0, 5x-3

y=0, 5x-2. Hence its gradient is 0,5

For line B, its you intercept is -8, so y=mx-8.

When x = -4, y=-4m -8 =0 as shown in the graph. This means that m = -2.

Since |-2| > |0, 5|, line B is steeper than line A.

Austin is 69 years younger than Jamie. 3 years ago, Jamie's age was 4 times Austin's age. How old is Austin now?
matrenka [14]

Answer: 26 years old

Step-by-step explanation:

  1. Create an equation with Austin as x and Jamie as x+69 (I just like workin with addition signs more)= 4(x-3)= x+69-3
  2. Simplify the equations --> 4x-12=x+66
  3. Solve the equation: 3x-12=66 --> 3x=78 --> x=26

This is the same as other age problems, just with the extra step of distributing the multiplication.
