I believe the answer is 2. A cone.
Answer:
option C

Step-by-step explanation:
The point slope equation of a line is given by

Where m is the slope and (x1,y1) is the point on the point

We need to write the equation in y=mx+b form
multiply -2/3 inside the parenthesis

Subtract 7 from both sides

Answer:
No solution
Option 4 is correct
Step-by-step explanation:
Given: The system of inequality


We need to choose correct option.
Option 1: (-5,2)
Put x=-5 and y=2
Equation 1 Equation 2


TRUE FALSE
Option 2: (2,2)
Put x=2 and y=2
Equation 1 Equation 2


FALSE FALSE
Option 3: (5,2)
Put x=-5 and y=2
Equation 1 Equation 2


FALSE TRUE
Option 1, 2 and 3 are incorrect because both equation must be true for solution.
Hence, Option 4 is correct no solution.
Answer:
11
Step-by-step explanation:
Let e represent the number of students with blue eyes. Then the number of students with blond hair is 2e. The total number of students is ...
3 + e + 2e -6 = 30
We subtracted 6 because the expressions e and 2e cause the 6 students with both blond hair and blue eyes to be counted twice.
3e = 33 . . . . add 3 and simplify
e = 11
11 students have blue eyes.
