Answer:

x > - 1 OR x < -1   .

Step-by-step explanation:

Given  : 5x - 29 > -34 OR 2x + 31 < 29.

To find : Solve .

Solution : We have given 5x - 29 > -34 OR 2x + 31 < 29.

For 5x - 29 > -34

On adding both sides by 29.

5x > - 34 + 29 .

5x > -5 .

On dividing both sides by 5.

x > - 1 .

For 2x + 31 < 29.

On subtracting both sides by 31 .

2x < 29 -31 .

2x < - 2 .

On dividing both sides by 2.

x < -1 .

So , x > - 1 OR x < -1 .

Therefore,x > - 1 OR x < -1   .

Which equation correctly represents the line graphed below?
Galina-37 [17]

Answer:

C. y=3/2 x + 12

Step-by-step explanation:

lets find slope,

fr that first lets point out some coordinates passing the line: ( 0, 12 ), ( 2,15 )

now find slope using the equation : y -y1/ x - x1

                                                         = 15 - 12 / 2 -0 = 3/2

  • use any coordinates now to find the equation of line using formula:

y - y1 = m ( x - x1 )

y - 12 = 3/2 ( x - 0 )

y -12 = 3/2 x - 0

<em>y =</em> 3/2 x + 12

Therefore, y = 3/2 x + 12 is the equation of the line.

cellular phone companies often package their products to make them more attractive to potential users. if you average 356 minute
Lemur [1.5K]

Answer: package B is the better deal.

Step-by-step explanation:

package A offers free phone and 300 minutes. it will cost 0.12 per minute for each minute over the plan time. Also, package A has a base rate of $39.95. This means that if you average 356 minutes per month in talk time, the cost using package A would be

0.12(356 - 300) + 39.95 = $46.67

package B : phone costs $10 and has 350 minutes of time and 0.08 per minute for each minute over the plan time. Also, package B has a base rate of 35.95 not including the phone. This means that if you average 356 minutes per month in talk time, the cost using package B would be

10 + 0.08(356 - 350) + 35.95 = $46.43

Therefore, package B is the better deal since it is cheaper.

One number is four less than a second number. Four times the first is 14 more than 5 times the second. Find the numbers.
8_murik_8 [283]

Answer:

First number is 6

Second number is 2

Step-by-step explanation:

The trick is that we need to set up two equations. Nor simplicity's sake I'm going to say the first number is x and the second number is y.

First we know that the first number (x) is 4 less than the second number (y).

Less means subtraction.

x-4=y

Then we know that 4 times x is 14 more than 5 times the second. More is addition and times is multiplication.

4x=14+5y

Now we use substitution to find out what x (the first number) is, subbing x-4 in for y.

4x=14+5(x-4)

4x=14+5x-20

-x=-6

x=6

First number is 6

Lastly, we sub 6 back into one of the equations. It's easier to us the first equation.

x-4=y

6-4=y

2=y

The second number is 2
