Let x = number of cups of ingredient B if 2 cups of ingredient A are used. Set up a proportion: (1/2)/(1 2/5) = (2)/x. Cross multiplying we get (1/2)x = (1 2/5)(2)
(1/2)x = 14/5, so x = 28/5 = 5 3/5 cups.
24 / (3/8) =
24 * 8/3 =
192/3 =
64......there are 64 three-eights quart jars
Answer:
y = -3x^2 + 4
Look below for more information
Step-by-step explanation:
y = 3x^2 - 4
Everything is wrong about this answer. The slope is actually a negative and the y-intercept is suppose to be a positive
y = -3x^2 - 4
Only the y-intercept is wrong here because the graph is going 4 units up instead of 4 units down
y = -3x^2 + 4
This is the correct answer! The slole is negative and the y-intercept is a positive
y = 3x^2 + 4
The slope is wrong but the y-intercept is correct!
Therefore, our answer is the third option: y = -3x^2 + 4
