Answer:

  RS = √(b² +(c -a)²)

Step-by-step explanation:

Put the given point coordinates in the given formula:

  • R = (x₁, y₁) = (0, a)
  • S = (x₂, y₂) = (b, c)

  RS = √((b -0)² +(c -a)²)

  RS = √(b² +(c -a)²)

Solve the following inequality. 4x-1> -9
pychu [463]
Solve inequalities the way you would solve an equation except for this rule-
If you multiply or divide a negative, the sign must be switched.

Do the inverse of everything like in an equation-
4x-1> -9
+1      +1 (Add 1)
4x>-8
/4    /4     (Divide 4)
You are not dividing a negative number from another number.  So keep the sign.
x>-2
Your answer is C.

Answers:
k = 13The smallest zero or root is x = -10
===============================
Work Shown:
note: 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.
