Answer:
x = 2
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
4x+14−2x=2x+18−2x
2x+14=18
Step 2: Subtract 14 from both sides.
2x+14−14=18−14
2x=4
Step 3: Divide both sides by 2.
2x
2
=
4

First, since all of the terms are multiplied, you can cancel them out to simplify them:
18/9 = 2
When a term has exponents on the top and bottom of a fraction, you subtract the bottom from the top:
c^8/c^3 = c^5
d^9/d^6 = d^3
So now, we can get rid of the fraction bar and put all of these terms into one expression:
2(c^5)(d^3)
Step-by-step explanation:
1.
when 3 coins are flipped the following outcomes are possible
h = heads, t = tails
h h h
h h t
h t h
h t t
t h h
t h t
t t h
t t t
yes, there have to be 8 options, because we have 3 positions with 2 possible outcomes. that means
2×2×2 = 2³ = 8 possibilities.
2.
at least 2 tails means 2 or 3 t in the list item :
h t t
t h t
t t h
t t t
3.
so, 4 out of the 8 possible outcomes. the probability is then therefore
4/8 = 1/2 = 0.5
Answer:
a) y = 6x - 3
b) 1/3y = 2x -1
The first thing you need to do is isolate (y) in the second equation
3 x (1/3y) = 3 x (2x - 1)
y =6x - 3
After isolating (y) in equation b they end up being the same.
Graphing:
In order to graph this, you have to make the first point at (0, -3) since this is the Y-intercept of the equation.
In order to graph the other points, you must move 6 units up and 1 unit to the right. Or vise versa If you need a visual I'll gladly link one.
Using the FOIL (First, Outside, Inner, Last) method, you multiply the two parenthesis together. First, you multiply x • x which = x^2, then outside, x • -3 = -3x. Next you multiply the inner number and variable, 2 • x = 2x, and finally the last values, 2 • -3 = -6. Then add all the values together (x^2 - 3x + 2x - 6) which equals the final answer x^2 - x - 6 :) Im not great at explaining but I hope this helps
