Suppose there are nine marbles in a jar. they are identical except in color. three are red, four are blue, and two are white. you are instructed to draw one
marble, note its color, and set it aside. then you are to draw out another marble, note its color and set it aside. draw a tree diagram showing all possible
outcomes for both drawings. write the probabilities on the branches and answer the following questions. reduce all fractions to lowest terms. no
decimals! (hint see page 180 of your book)
its 60-10+x why, because she bought the dress with $60 and she received $10 dollars back. We don't know the variable.
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Hope this helps!
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.
Step-by-step explanation:so you want to start by putting 2/3+4 together to get 4 2/3 and then divide it by -2
