Y = x + 2
if x = -3 then y = -3 + 2 = -1 so it's (-3,-1)
if y = x + 2 reflected across x-axis then x will stay the same but y is opposite
rule: reflected over x-axis (x,y) --->(x, -y)
so (-3,-1) will be ((-3,1)
answer
y = 1 when x = -3 reflected across x-axis
There are 7 nickels and 8 dimes, if you look closely at the procedure, you can see how <em>x </em>is established for the nickels (0.05) and <em>y </em>for the dimes (0.10).
Does #13 have a division sign?
One batch:
1 pouch of tuna
26 oz of mayonnaise
Double batch means multiply by 2:
1 pouch × 2 = 2 pouches of tuna
26 oz × 2 = 52 oz of mayonnaise (or 1474g)
