Just dont even try with these use a calculator every time. even if you're confident
Answer:
238
Step-by-step explanation:
Start with Raven's ants since hers is the one that everyone else's is based off of.
Raven = 208
Haley has half of that plus 76, so
Haley = (208/2) + 76
Haley = 180
If Haley's farm doubles in population, she would have 360 ants. That number is equal to Nate's number + 122. We have an equation of sorts there to solve for Nate's ants:
180(2) = N + 122 so
360 = N + 122 and
N = 238
Nate has 238 ants in his farm.
Answer: The system of equations have many solutions and the correct options are A,B and D.
Explanation:
The given equations are,
..... (1)
.... (2)
Simplify the second equation.


Divide both sides by 3.

It is same as equation (1). Since equation (1) and (2) are same, therefore all the points lies on the line or which satisfies the equation are the solution of the given system of equations.
Test the points whether the point lies on the line or not.
Check for point A(6,-7).


LHS and RHS are equal, therefore the point A is the solution of the system of equations.
Check for point B(2,1).


LHS and RHS are equal, therefore the point B is the solution of the system of equations.
Check for point C(-2,-9).


LHS and RHS are not equal, therefore the point C is not the solution of the system of equations.
Check for point D(-4,13).


LHS and RHS are equal, therefore the point D is the solution of the system of equations.
Therefore the options A,B and D are correct.
Answer:
y = 2
Step-by-step explanation:
Rearrange
2y = 7 - 3
2y = 4
make y on its own
y = 2
Answer:
B & C
Step-by-step explanation:
A proportional relationship has a proportionality constant (constant rate of change) and and must cross through the origin (or begin at (0,0). This means it's y-intercept is 0. Each of the options is a linear function. All of the functions have a constant rate of change. Only one as b=0 or 0 as the y-intercept.
B) y=4x has a constant of 4 and passes through the origin.
C) y=7x has a constant of 7 and passes through the origin.
