This is what I got, but you might want to double check me because I'm not that good at math (this is what I got for the discontinuity);
1. f(x)= x^2+6+8/x+4
*x+4=0
-4 -4
x= -4
This means that x cannot equal -4
2. f(x)= (x+2)(x-4)/(x+2)(x+2)
*Note: When I did my calculations, I cancelled out all (x+2) binomials except for one in the denominator*
f(x)= x-4/x+2
*x+2=0
-2 -2
x= -2
This means x cannot equal -2
*You may want to check my work, but I believe that your answer is going to be either C or D. Personally, I assume it's C, but that's just me. Anyway, it's probably going to be C or D, or at least that's what I think.*
One quarter
quarter means 4
so one quarter is 1 out of 4
or the fraction 1/4
or the decimal 0.25
Hope this helps!
Answer:
5x - 2y = -10 (B.) This should be right so if its not let me know I am stumped on what else it would be
Step-by-step explanation:
Parallelism: Same slope but different y-intercept
1 - Get into slope formula
5x - 2y = 7
<u>- 5x -5x </u>
-2y = -5x + 7
-2y/-2 = -5x/-2 +7/-2
y = (5/2)x - 7/2
2 - Plug x and y from (0, 5) into y = mx + b however note the - 7/2 is extranneous and wont be used for b
y = (5/2)x + b
5 = (5/2)0 + b
5 = 0 + b
5 = b
Therefore
y = 5/2x + 5 is your slope formula.
Now to get x to the other side.
3 - Get it back to standard form.
y = 5/2x + 5
- 5/2x -5/2x
- 5/2x + y = 5
(Multiply 2 into everything to get rid of the fraction)
-5x + 2y = 10
The equation for this problem would be 56=2x+5x, which can be simplified to 56=7x, x being the number of cups of soda. To find x you must get it alon be dividing both sides by 7 (56/7=7x/7). Doing this gives you 8=x, or in other words 8 cups of soda.
Hope this helps!
