The parabola vertex is B. (2,2)
Explanation in photo provided.
So the ratio is 40/26 = 1.54
24 ÷ 1.54 = 15.58
2x-4 = 15.58
2x = 19.58
x = 9.8
Answer:
16 girls
Step-by-step explanation:
there are 4 out of 7 girls in the class.
28/7=4 (this is the unite rate per group number)
4 x 4 =16
If you would like to calculate g * 5 - h * 3 for g = 2 and h = 7, you can do this using the following step:
g = 2
h = 7
g * 5 - h * 3 = 2 * 5 - 7 * 3 = 10 - 21 = - 11
The correct result would be - 11.
