Answer: Im gonna say 12
Step-by-step explanation:
Answer:
I think the answer is m= -1/3 b=7/3
Explanation:
so first, you need to make equations using the info that the question gave.
f(-2)= m(-2)+b f(4)= m(4)+b
= -2m+b =4m+b
f(-2)= 3 f(4)= 1
-2m+b= 3 4m+b=1 -(2)
b= 3+2m -(1)
substitute (1) into (2) : 4m+(3+2m)=1
4m+2m+3=1
6m=1-3
6m= -2
m= -2/6
m= -1/3
Substitute m= -1/3 into (2)
4(-1/3) + b=1
-4/3 +b =1
b= 1+ 4/3
b= 7/3
Therefore, m= -1/3 b=7/3
and that's how you do it
Step-by-step explanation:
x² - 14x - 51 = 0
(x² - 17x) + (3x - 51) = 0
x(x - 17) + 3(x - 17) = 0
(x + 3) (x - 17) = 0
x + 3 = 0 eq1
x = 0 - 3
x = -3
x - 17 = 0 eq1
x = 0 + 17
x = 17
