You can simplify the entire equation by dividing it all by 7, resulting in 7(b^2-6b+20).
Here, you can factor as you normally would. Your X values would have to be found using the quadratic formula.
Answer:
k= -1
Step-by-step explanation:
To find k, use the points and the m =-7 in the slope formula:
Substitute 1 for x in each of your equations.
f(x)=7-3x
which is
f(1)=7-3(1)
=3
Do the same for g(x)
g(x)=3x-7
which is
g(1)=3(1)-7
=-4
Then subtract g(x) from f(x):
3-(-4)
=7

2x-1=5
2(3)-1=5
6-1=5
5=5
x=3
Answer:
42
Step-by-step explanation:
5 more than 2 times the girls
89=5+2x
