Answer:
k = 13The smallest zero or root is x = -10
Step-by-step explanation:
you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
First, factor each expression by finding two terms whose product is equal to the c term and sum is equal to the b term.
x^2-x+6 --> (x-3)(x+2)
x^2-4 --> (x+2) (x-2)
Next, cancel the terms that are equal on the top and bottom.
You are left with the answer of:

Answer:
The slope of line y=-8 is 0, and any line that lies parallel to it will also be 0. This is because if an equation does not have an x-value, the line will be straight and horizontal, making it's slope 0.
Well you multiply the outside with the inside———- for instance
-4 • -4 = 16^3
-4• -4 = 16
-4 • 3 = -12v^3
So 16^3 + 16 - 12v^3 do the powers & your done
