The symbol "<=" without quotes means "less than or equal to"
-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21
So the answer is choice D
Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest
5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false
The 3rd one in the picture
The equation is
X = 2
because if it's parallel to the y axis, it goes straight through one single X co-ordinate.
Answer:
1. So if you want to know how is math related to baking, I will show you how. Firstly, if you bake a cake, you'll all have to use some measurement, and if you calculate anything wrong or place the crazy amount, the cake you're trying to bake would turn out awful. That's where maths come to play. You would have to calculate ratios and much more, for example, one tee-spoon of sugar to 2 tee-spoons of water it's a 1:2 ratio of sugar to water. If you try to make double the amount of cake, then you'll all have to double the ratio, too, so the ratio will become 2:4, and that's how we would use math in baking a cake. If you for any reason put more than the required amount, the whole cake would be ruined like it might be too sugary, and you will have to retry and bake another one.
2. Yes indeed I've tasted a mess up the cake, and I think that the problem was that the cake batter was much sugary than I expected and that's why you guys have to calculate the perfect amount of ingredients, and that's how maths would help us in baking a cake
hope this helps you btw
