The equation can be written in vertex form as
  y = a(x +2)² - 3
Substituting the given values, we can find the coefficient "a".
  -5 = a(-1+2)² -3
  -2 = a . . . . . . . . . add 3 and simplify

The coefficient of the squared term is -2.

Ben is taking three AP classes and two regular classes. His AP classes count twice as much as his regular classes in his GPA. Ea
zhannawk [14.2K]
This problem deals with a weighted average. Since the AP classes count twice as much as regular classes, their grades must be counted twice. It's as if for each AP class he's taking, he was taking two classes. The points of each AP class grade is added twice, and the each AP class counts as 2 classes in the number of classes.

Each AP class counts twice and counts as 2 classes.

Class                                Ben's grade     Points          Number of Classes
AP English                               B               3 + 3                         2
AP Government                       B               3 + 3                         2
AP Algebra II                           A                4 + 4                         2
Spanish                                   B                   3                            1
Physics                                    D                  1                            1
TOTALS                                                       24                           8

GPA = (total points)/(number of classes) = 24/8 = 3

Seamstress Jane has purchased 50 yards of red fabric and 110 yards of gold fabric to make red and gold curtains. What is the lar
Alisiya [41]

Answer: There are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

There are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

Step-by-step explanation:

Since we have given that

Number of yards of red fabric purchased by Jane = 50

Number of yards of gold fabric purchased by Jane = 110

We need to find the largest number of curtains she can make if she wants all the curtains to be exactly the same length.

For this we will find H.C.F. of 50 and 110.

Factors of 50 = 1, 2, 5, 10, 25, 50.

Factors of 110 = 1, 2, 5, 10, 11, 22, 55, 110.

So, Highest common factor of 50 and 110 is 10.

So, there are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.

Number of yards of red fabric is given by

\frac{50}{10}=5

Number of yards of gold fabric is given by

\frac{110}{10}=11

Hence, there are 5 red fabrics and 11 gold fabrics that would be used for each curtain.
