Solve and graph the absolute value inequality: |2x + 4| > 8​

Mathematics
1 answer:
neonofarm [45]3 years ago
4 0

Answer:

C

Step-by-step explanation:

To get rid of the absolute value bars you have to get two different equations which would be 2x+4>-8 AND 2x+4>8. Pay attention to the signs, if there is greater than or equal to then it would have a line underneath the sign, which neither of the equations should have since you haven't moved a negative. solve normally and you'll get -6 blank circle and 2 blank circle.

The ratio of blue tacks to red tacks on the bulletin board is 3 to 5. there are 50 red tacks. how many blue tacks are on the boa
natulia [17]
3:5=x:50

Therefore 5 ×x = 50

x = 10

Therefore 3 × 10 = 30

therefore 30 blue pens

proof = 30 blue + 50 red= 3+ 5

therefore 80 = 8x

One month, ruby worked 8 hours more than isaac, and svetlana worked 4 times as many hours as ruby. together they worked 136 hour
Travka [436]

Let Issac work for x hours, and Ruby works 8 hours more than of Issac, so Ruby work for (x+8) hours.

And Svetlana worked four times of Ruby, therefore Svetlana worked for

4(x+8) hours

And total hours they worked together is 136. That is

x+x+8 + 4(x+8) = 136
\\
x+x+8 +4x+32=136
\\
6x+40 =136
\\
6x=96
\\
x =16 hours

So Issac worked for 16 hours, Ruby worked for 24 hours and Svetlana worked for 24 times 4 equals 96 hours .

Determine the equation of the line with slope 5 that passes through the point M(1, 2).
Nezavi [6.7K]
You're already given the slope, so the first step you must take is to find the y-intercept. To do this, you substitute the values of the coordinate M into y = 5x + c, with the x value substituting x and the y value substituting y. This gives us:
2 = (5 × 1) + c
2 = 5 + c
- 5
-3 = c

So now you know that the y-intercept is -3, you can see that your final answer must be the first option, y = 5x - 3.

I hope this helps!

2 more to go!!!! HELP ME!!!!!
Musya8 [376]

To divide complex numbers, you multiply by the conjugate. The conjugate is when you change the sign between the two terms in the denominator. Therefore, the conjugate in this one is (3+i)


\frac{13-i}{3-i} * \frac{3+i}{3+i} ← Then, you foil these guys:


\frac{(13-i)(3+i)}{(3-i)(3+i)} = \frac{40+10i}{10} = 4 + i or C
