Answer:
[6, infinity)
Step-by-step explanation:
Y-y1= m(x-x1)
y-2= -2(x+6)
y-2= -2x-12
y= -2x-10
Unless there is supposed to be a zero at the end of that 1, then the answer is no
Answer:
80
Step-by-step explanation:
Initial ratio:
Teachers to students
1 : 15
Ratio after:
Teachers to students
3 : 40
The number of students did not change, so we can make the students of the initial ratio and the students of the ratio after the same.
1 : 15 = 8 : 120
3 : 40 = 9 : 120
120 units = 1200
1 unit = 
Initial teachers = 8 units = 
Answer:
x = -7
Step-by-step explanation:
5-x=12
To solve for x, you must first make the equation equal to x (to make x alone on one side).
5 - x = 12
-5 -5
-x = 7
-x(-1)=7(-1)
x = -7
Answer:
x=45
Step-by-step explanation:
Because angles that are vertical to each other are congruent that means 2x+6=96
-6 -6
2x=90
2(45)=90
