Answer:
B = G + 7 and B + G = 29
Step-by-step explanation:
Let B = boys and G = girls. There are 7 more boys then girls. Set the equation:
B = G + 7
There are 29 students in total. Set the boys and girls equal to the total amount:
B + G = 29
B = G + 7 and B + G = 29 is your answer.
~
F(x)=-2x+4x-7
f(x)=2x-7
now f(-4)=2(-4)-7=-8-7=-15
So it will be -15
