There would not be two Y-Intercepts, so it is either B or C
Since you can determine the intercept through the equation y=mx+b and b in this equation is 600 so the answer is C
Answer:2
Step-by-step explanation:
Given
Physics problem requires 20 min
Math problem require 10 min
suppose x question of Physics and y questions of Math are done
so according to the question

Time require for x Physics problem 
Time require for y Math problem 
so,

On solving (1) and (2)
we get
and 
Maximum no of Physics question which can be solved is 2
Answer:
Blue is linear; orange is nonlinear
Step-by-step explanation:
linear is straight
nonlinear is not
Let
x--------> the number of blue beads
y--------> the number of red beads
we know that

-------> equation 
------> equation 
equate equation
and equation 

find the value of x

therefore
the answer is
Ivan has

Answer:
x = - 7
Step-by-step explanation:
( x + 139 ) and 132 are vertically opposite angles.
Vertically opposite angles are equal,
x + 139 = 132
x = 132 - 139
x = - 7
