Answer:
y = 3/7x + 51
Step-by-step explanation:
y = 3/7x + 11 is parallel to the line so it means that both of their gradient are same so:
y = mx + c
m= gradient point = (-21 , 42)
= 3/7
now we sub the m and the point into the formula which is y= mx+c because we should find the c first then we can find the equation of the line:
42 = 3/7 (-21) + c
42 = -9 + c
42 + 9 = c
51 = c
c = 51
now you hv to rewrite again the equation become y= 3/7x + 51
So now your final answer is : y = 3/7x +51
AB = 12
BC = 5
AC = 3
To find AC, we can use the pythagoras theorem, square root of 12 power of 2 + 5 power of 2 and we can get 12. Hope this help!
Answer:
5x+12=-14=180
Step-by-step explanation:

If 4 is a root, then a factor must be x - 4.
Only choices A and D have x - 4 as a factor.
Now look at the constant term of each binomial in the factorizations of choices A and D.
A.: -4, 4, 5
Their product is -80.
The constant term of the original polynomial is -40, so this factorization cannot be correct.
D.: -4, 2, 5
Their product is -40.
This is the correct factorization.
Answer: D.
Slope-intercept form: y=mx+b
