What is the inequality -3x + 1 < 7 look like on a number line.

grandymaker [24]

Step-by-step explanation:

First you must simplify the equation:

$-3x+1$

subtract 1 from both sides:

$-3x$

than divide both sides by -3, which switches the inequality sign:

$x>-2$

This inequality means that all values of x greater than -2 work for the equation. because it is not $\geq$ , -2 is not included, so there will be a hollow circle there. than the inequality will have a line from that dot to the right so that all values of x that work for the inequality are on that line.

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

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