After harvey islip's performance review, he received a merit increase of...
Let x be his previous hourly rate
24 = x + 0.0365x + 0.0335x
24 = 1.07x
X = 24 / 1.07
X = $ 22.43 is his hourly rate before the merit and COLA increase
its 60-10+x why, because she bought the dress with $60 and she received $10 dollars back. We don't know the variable.
Answers:k = 13The smallest zero or root is x = -10
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.
