Answer:
1. I have simplified the first question:
![x=\frac{10-ab}{a-4};\quad \:a\ne \:4](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B10-ab%7D%7Ba-4%7D%3B%5Cquad%20%5C%3Aa%5Cne%20%5C%3A4)
2. I have found the parabola properties:
![\left(h,\:k\right)=\left(\frac{5}{2},\:\frac{25}{4}\right),\:p=-\frac{1}{4}](https://tex.z-dn.net/?f=%5Cleft%28h%2C%5C%3Ak%5Cright%29%3D%5Cleft%28%5Cfrac%7B5%7D%7B2%7D%2C%5C%3A%5Cfrac%7B25%7D%7B4%7D%5Cright%29%2C%5C%3Ap%3D-%5Cfrac%7B1%7D%7B4%7D)
Just to clarify, the way he explained is backwards.
8 sisters
3 eggs
8 sisters split 3 eggs, not 3 eggs split 8 sisters.
therefore, Aliens
therefore, 3 eggs divided by 8sisters
3/8 = amount of egg per sister
8/3 = number of sisters per egg.
Answer:
c
Step-by-step explanation:
c is the point (2,3) in the question
I think it’s 9.5 because it’s a square so all the sides should be equal and you divide 38 by 4 because it has 4 sides
Answer:The inequality is
x greater than or equal to(>/=) 14
Step-by-step explanation:
Let x represent the possible cost of the full pizza. Tara eats 3 of the 10 slices and pays $4.20 for her share. This means that the amount of pizza that Tara ate is 3/10×x = 3x/10
Assuming that Tara has paid at least her fair share, therefore
3x/10 = 4.20
3x = 4.20 ×10 = 42
x = 42/3 = 14
This means that the total cost of the pizza is at least $14. The inequality
how much the pizza could have cost becomes
x greater than or equal to(>/=) 14
