Y=30x+50
y is the total amount saved
x is the amount of months she deposited 30 dollars
30 is the amount she’s depositing
50 is the initial amount or the constant
Slope of AB=(2-3)/(1+1)=-1/2; AC=(-1-3)/(-3+1)=-4/-2=2; BC=(-1-2)/(-3-1)=-3/-4=3/4.
The product of two sides that are perpendicular is -1. Slopes of AB and AC are perpendicular so angle A is a right angle. ABC is a right-angled triangle.
She should have
nickles: 6 . =30
dimes: 30 . = 300
=330 . or $3.30
Answer:
2(x-1)(x+1)
Step-by-step explanation:
x2x-2
=2(x^2-1)
=2(x-1)(x+1)
