Step-by-step explanation:
solution
let,A(5,-1)
given
y=12x-1
or, y = 12 × x + (-1)
comparing it with y=mx+c
we get
x=1
y = c = -1
now
A(5,-1) and B(1,-1)
equation of line is,
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
or, (y+1)/(x-5) = (-1+1)/(1-5)
or, (y+1)/(x-5) = 0/-4
cross multiply
-4y-4 = 0
or, 0=4y+4
or, 4y+4=0 is the required eqn
I think this is the process and answer too.
I hope this helps you

Took the test
Answer:
Length of crab in x years = x + 2
Step-by-step explanation:
Since the crab grows 1 inch per year, and it would grow:
1 inch in the 1st year
2 inches in the 2nd year
3 inches in the 3rd year
4 inches in the 4th year
.
.
.
And so on.
However, in order to find the total length, you need to remember that the crab is originally 2-inches long. So the total length after x years would be the number of inches it grew over the years (x) + the length before the growth (2).
Thus, Length of crab in x years = x + 2
Answer:
this is all I could find I hope it helps
Considering the sum and the product of the roots of the quadratic equation, it is found that the numeric value of the expression is given as follows:

<h3>What are the sum and the product of the roots of a quadratic equation?</h3>
A quadratic equation is defined as follows:

The roots of the equation are given as follows:

The sum of the roots is given as follows:

The product of the roots is given as follows:

In the context of this problem, the product is of 4, as
hence:
c/a = 4
c = 4a.
The coefficients are in an arithmetic progression, hence:
- b = a + d. (d is the common difference of the sequence).
We have that c = 4a, hence:
4a = a + 2d
2d = 3a
d = 1.5a.
Hence coefficient b is calculated as follows:
b = a + d = a + 1.5a = 2.5a.
Then the sum of the roots is given as follows:
