Me :           4 x + 8 y   =  64
My friend:  8 x + 16 y = 128
A ) 4 * 4 + 8 y = 64
     16 + 8 y = 64
     8 y = 64 - 16
     8 y = 48
     y = 48 : 8
     y = 6 ( me and my friend work 6 hours at the second job )
B )  The number of hours we each work at the first job are also the same.

Based on the work shown on the right, check all of the possible solutions of the equation.
Mazyrski [523]

Incomplete question. However, here is a similar question attached.

Solve 3x^2 + 17x - 6 = 0.

Based on the work shown to the left, which of these values are possible solutions of the equation? Check all of the boxes that apply

A X=-6

B X=6

C X=-1/3

D X=1/3

E X=0

Answer:

A and D

Step-by-step explanation:

Note that such question requires using completing the square method of solving equations. By using the values X= -6 and X= 1/3 we arrive at a solution.

Please help quick will give brainliest!

Answer: Choice A) There must be a vertical asymptote at x = c

Explanation:

The first limit \displaystyle \lim_{x\to c^{-}}h(x) = -\infty says that as x approaches c from the left side, the f(x) or y values approach negative infinity. So the graph goes down forever as x approaches this c value from the left side.

The limit \displaystyle \lim_{x\to c^{+}}h(x) = \infty means that as x approaches c from the right side, the y values head off to positive infinity.

Either of these facts are enough to conclude that we have a vertical asymptote at x = c. We can think of it like an electric fence in which we can get closer to, but not actually touch it.

6(x-5) = 5(x+5)
Mariana [72]

Part 1:

6(x-5) = 5(x+5) (x = 55)

4y + 2 (-3 + 2y) = 1-y (x = 7/9)

Part 2:

4(a-6) = 8a - (4a-24) (No Solution)

4(2x-8) = 8(x-8) (No Solution)

2(3x-3) = -6x-6 (Identity (x = 0))

A bike cost $500 and another costs $600 the more expensive bike Is 20% more that the other justify your answer.
Vsevolod [243]
The more expensive bike could be a bigger size so in stead of being a 20 inch it could be a 24 inch, another option is that one bike is made by a lower brand name company hile the expensive one is a better well know company so in that case the extra $100 is just a added price for the name. Last option is one's on sell and ones not. I hope this helped! :)
