Answer:
y=1/4x-1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-(-2))/(8-(-4))
m=(1+2)/(8+4)
m=3/12
m=1/4
y-y1=m(x-x1)
y-(-2)=1/4(x-(-4))
y+2=1/4(x+4)
y=1/4x+4/4-2
y=1/4x+1-2
y=1/4x-1
Answer:
154 because we multiply the 11in and 14 in to get 154 inches so h = 154 inches
By concepts of polynomials and systems of linear equations, the constants c and d of the expression p(x) = x⁴ - 5 · x³ - 7 · x² + c · x + d are 29 and 30.
<h3>How to determine the missing coefficients of a quartic equation</h3>
A value x is a root of a polynomial if and only if p(x) = 0. We must replace the given equation with the given roots and solve the resulting system of <em>linear</em> equations:
(- 1)⁴ - 5 · (- 1)³ - 7 · (- 1)² + (- 1) · c + d = 0
- c + d = 1 (1)
3⁴ - 5 · 3³ - 7 · 3² + 3 · c + d = 0
3 · c + d = 117 (2)
The solution of this system is c = 29 and d = 30.
