Answer: User got this. x=50+6/7 is the Answer.
Step-by-step explanation:
Step 1) Move all terms to the left:
(x+4)7/3-(128)=0
2) Multiply all the terms by the denominator
(x+4)7-128*3=0
3) Add all the numbers together, and all the variables
(x+4)7-384=0
4) Multiply parentheses
7x+28-384=0
5) Add all the numbers together, and all the variables
7x-356=0
6) Move all terms containing x to the left, all other terms to the right
7x=356
x=356/7
x=50+6/7
Let us represent the slots of sweaters with dashes:
_ , _ , _ , _ , _ , _
The first slot has 10 possibilities, the next has 9, the next has 8 and so on.
10 x 9 x 8 x 7 x 6 x 5
= 151200 arrangements
Answer:
The value of k is -2
Step-by-step explanation:
The cut point with the y axis for both graphs occurs when x = 0
We have then:
For f (x):
The cut point with the y axis is:
For g (x):
The cut point with the y axis is:
Therefore, the value of k is given by the vertical displacement of the graph k units.
We have then:
From here, let's clear k:
I am not sure if this helped. But, I hope it did. I ma sorry if you get it wrong.
Answer:
Step-by-step explanation:
5/14=x/28
Cross multiply to get
14x=140
Divide both sides by 14
x=10
Or
See that 28 is 14*2 and multiply 5*2 to get the same answer
IF K is the midpoint of JL then JK = KL, so...
5x + 1 = 7x - 3
5x = 7x - 4
-2x = -4
x = 2
JK = 5(2) + 1 = 11
JL = 2 * JK = 2 * 11 = 22
