<span>P(x) = x</span>³<span> + 5x</span>²<span> – x – 5
P(x) = x</span>²(x+5) - (x + 5)
P(x) = (x + 5)(x² - 1)
P(x) = (x + 5) (x + 1)(x -1)

Step-by-step explanation:
The equation has the form Y= a + bX,
Where:
Y is the dependent variable (that's the variable that goes on the Y axis).
X is the independent variable (i.e. it is plotted on the X axis).
b is the slope of the line.
a is the y-intercept.
Answer:
Step-by-step explanation:
Given the expression 4^{-2}•7^{-2}. The following expression are equivalent to given expression on simplification.
Generally from indices, a^-b = 1/a^b. Applying this to the given expression we have:
4^{-2}•7^{-2} = 1/4^2 • 1/7^2
= 1/(4×4) • 1/(7×7)
= 1/16 • 1/49
= 1/(16×49)
= 1/784
Answer:
y= -2x-7
Step-by-step explanation:
point-slope: y-y1=m(x-x1)
y-3=-2(x-5)
y-3=-2x-10
y=-2x-7
