$15.81
15% of $20 is $3 so subtract that from $20 and u get $17.
Then 7% of $17 is $1.19 so subtract that from $17 and you get $15.81, which is the amount Lin’s father would pay for the meal in the end.
Addition or something else i think 11x 5
Hi there! :)
We are given 2 points. It means we can use the following formula to find the slope:
m=
m=
So the slope is -3
First, let's write the equation of the line in point-slope form.
y-y1=m(x-x1)
y-(-6)=-3(x-0)
y+6=-3(x+0)
y+6=-3x+0
y=-3x+0-6
y=-3x-6
Hope this helps!

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x(x² + 4x - 5)
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x </em>[Function]: f(-2) = 3(-2)[(-2)² + 4(-2) - 5]
- [Brackets] Evaluate exponents: f(-2) = 3(-2)[4 + 4(-2) - 5]
- [Brackets] Multiply: f(-2) = 3(-2)[4 - 8 - 5]
- [Brackets] Subtract: f(-2) = 3(-2)[-4 - 5]
- [Brackets] Subtract: f(-2) = 3(-2)(-9)
- Multiply: f(-2) = -6(-9)
- Multiply: f(-2) = 54
