Answer:
5y = 4x + 10
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
So we change <em>4x + 5y = 10 </em>to the form in the answer.
Calculate Δ = b^2 -4ac => Δ = 169 => k1 = 3/2; k2 = -5 => 2k^2 + 7k - 15 = 2*(k -3/2)(k+5) = (2k - 3)(k+5);
Answer:
The nail would be 30 feet above the ground in 10 years.
Step-by-step explanation:
We are given the following in the question:
Height of nail = 10 feet.
The tree grows taller at a rate of 2 feet per year.
Thus, the height of nail can be represented by a linear function:

where t is the number of years.
We have to find the height of nail in 10 years.
Putting t = 10, we get,

Thus, the nail would be 30 feet above the ground in 10 years.
Answer:
On a coordinate plane, a triangle has points (negative 4, 3), (negative 4, negative 2), (1, negative 2).
Step-by-step explanation:
The points (-4,3), (1,2) and (-4, -2) would form a right triangle when graphed and connected by lines.
(-4,3), (1,2) and (1,3) would also work as well
