5x + 3 = 33
Our goal is to isolate 5x and then simplify.
5x isn't currently isolated, due to +3.
Perform the opposite order of operations.
Subtract 3 from both sides.
5x = 30
Now, we must simplify (solve for x).
X is being multiplied by 5, so we need to perform the opposite order of operations in order to solve for x.
Divide both sides by 5.
You are left with:
X = 6.
I hope this helps!
6 marbles, since (2/3)*9 is 6.
Answer:
The vertex is at (3, -4).
Step-by-step explanation:
You need to convert the function to vertex form.
f(x) = (x - h)^2 + k is vertex form where (h, k) are the coordinates of the vertex.
f(x) = x^2 -6x+5
First we divide the -6 by 2 and convert x^2 - 6x to a squared term and a constant term:
x^2 - 6x + 5 = (x - 3)^2 - 9 + 5 [ we subtract the 9 because (x - 3)^2 = x^2 - 6x + 9)
= (x - 3)^2 - 4 which is vertex form and the required vertex is (3, -4).
Answer: A
Step-by-step explanation:
(Friend 1, Friend 2)
Friend 1 = x
Friend 2 = y
(x, y) variables are substitution for the flavors
So it cant be C or D
B doesn't have all the possible solutions
Answer:
To find the gradient it's the difference in the y values divided by the difference in the x values.
