please help really simpleeeeeeeeeeeee plsssss help really simple i am just checking my awnser pease tell me what would the coord
inates be after the triangle P' Q' R' is reflect over the y-axis would be the coordanites are P'(1, 0), Q'(0, −1), and R'(−2, −1).

Answer:
P(-1, 0); Q(0, -1); R(2, -1).
Step-by-step explanation:
When you reflect coordinates over the y-axis, the y-coordinates do not change, while the signs of the x-coordinates are flipped. You can see the example attached!
And so, after reflecting P'(1, 0), you would get P(-1, 0) because the sign of the x-value is flipped and the y-value does not change.
Q'(0, -1) becomes Q(0, -1) because 0 is neither negative nor positive, and the y-value does not change.
R'(-2, -1) becomes R(2, -1) because the sign of the x-value is flipped to positive and the y-value does not change.
Hope this helps!

Answer:
From our calculations the large jar is the best value for money because a penny buys more honey
Step-by-step explanation:
<h2>In this problem we are expected to determine which purchase of honey is the cheapest ? large jar or small jar ?.</h2><h2 />We will determine which has the best value for money using the quantity a pound can purchase.
firstly for the large jar.
if £4.10 will purchase 540g of honey then,
£1.00 will purchase xg
cross multiplying to find x will have
Hence for the large jar a penny would buy 131.7g of honey
secondly for the small jar
if £2.81 will purchase 360g of honey then,
£1.00 will purchase xg
cross multiplying to find x will have
Hence for the small jar a penny would buy 128.1g of honey
