Which of the point-slope equations below are correct for the line that passes through points (-4,-14) and (1,3)?

Scrat [10]

(-4,-4)(1,3)
slope = (3 - (-4) / (1 - (-4)
slope = (3 + 4) / (1 + 4) = 7/5

y - y1 = m(x - x1)...using (-4,-4)
slope(m) = 7/5
y - (-4) = 7/5(x - (-4) =
y + 4 = 7/5(x + 4) <==here is one

y - y1 = m(x - x1)..using (1,3)
slope = 7/5
y - 3 = 7/5(x - 1) <== here is the other one

What is a equation that has a zero of -2 with a multiplicity of 3, a zero of 1 with a multiplicity of 1, degree of 4, and rises

zloy xaker [14]

Answer:

x^4+8x^3+18x-27=0

Step-by-step explanation:

In a equation of the form

$(x-a)^n(x-b)^m=0$

you have roots in x=a and x=b, and multiplicity of n and m respectively.

Hence, the equation is

$(x-(-2))^3(x-1)=0\\(x+2)^3(x-1)=0\\$

by expanding the factors you have

$(x^3+3x^2(3)+3x(3)^2+(3)^3)(x-1)=0\\(x^3+9x^2+27x+27)(x-1)=0\\x^4+9x^3+27x^2+27x-x^3-9x^2-27x-27=0\\x^4+8x^3+18x^2-27=0$

Answer:

Step-by-step explanation:

x+x+1+x+2 = 15+x+2

3x+3=x+17

3x=x+14

2x=14

x=7

7+8+9=24
