Answer:

2

Step-by-step explanation:

-2x+y=-7

Take the -2x and put it on the other side of the equation by changing the sign

y=-7+2x

Now put it in y intecpet form by putting the 2x first

y=2x-7

Slope is the number before the x.

so 2

Now knowing that parallel lines always have the same slope the answer is 2

Answer:

What do you mean?

Step-by-step explanation:

Answer:

Step-by-step explanation:

 x - 3y = 5

2x +  y = 10  multiply by 3 to eliminate y and solve for x

 x - 3y = 5

6x + 3y = 30  then add

7x          = 35

simplify:

x = 35 / 7

x = 5  

substitute x = 5 back into the eq.2

 2x +  y = 10

2(5) +  y = 10

           y = 10 - 10

           y = 0

therefore the answer is ( 5, 0 )

Answer:

2x^4

Step-by-step explanation:

As the magnitude of x gets larger, the absolute value of x gets large

The higher degree terms are going to grow much faster than the lower degree terms, so that is what we need to focus on

The highest degree terms here in the numerator and denominator are 8x^6 and 4x^2, so let's divide the two, and simplify to get our solution;

f(x) = (8x^6) / (4x^2)

= 2x^6 / x^2 = 2x^(6 - 2)

= 2x^4 (solution)

Answer:

0.82%

Step-by-step explanation:

First find the z-score.

z = (x − μ) / σ

z = (72 − 60) / 5

z = 2.4

Use a chart or calculator to find the probability.

P(Z > 2.4) = 1 − P(Z < 2.4)

P(Z > 2.4) = 1 − 0.9918

P(Z > 2.4) = 0.0082

Hence, the probability of time does it take longer than [tex]72[/tex] minutes if the standard deviation is [tex]5[/tex] minutes is [tex]0.82[/tex]%.

What is the probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Here given that,

If an hourglass takes an average of one hour to empty a full cycle.

Now, First find the z-score.

[tex]z = (x-[/tex] μ[tex])[/tex]/σ

[tex]z = \frac{72 - 60}{5}\\z = 2.4[/tex]

Now, using the calculator to find out the probability.

[tex]P(Z > 2.4) = 1 - P(Z < 2.4)\\\\P(Z > 2.4) = 1 - 0.9918\\\\P(Z > 2.4) = 0.0082[/tex]

Thus,

[tex]0.0082(100)=0.82[/tex]%

Hence, the probability of time does it take longer than [tex]72[/tex] minutes if the standard deviation is [tex]5[/tex] minutes is [tex]0.82[/tex]%.

Answer:

x = 2

Step-by-step explanation:

The topic here is "fractional exponents."

Review:  2^3 = 8 (this is the cube of 2), and so the inverse function is

            8^(1/3) = 2    ("8 raised to the fractional exponent 1/3 is 2"

Question a)  49^(1/2) ("49 to the power 1/2") can be rewritten as

(7^2)^(1/2), which simplifies to 7^(2*1/2) = 7^1  =  7

Caution:  this is exponentiation, not division.  So 49^(1/2) does not equal 49/2.

Question b)     (     )^(1/3)  =  4

I would prefer to write this as x^(1/3) = 4 and set the goal of finding the value of the base, x.

Then x^(1/3) = 4   ("x raised to the power 1/3 is 4")

Let's elimiinate the fractional exponent on the left by cubing both sides of the equation:

{x^(1/3)}^3 = 4^3, or, after simplification,

x^1 = 64, or, in simplest form,

x = 64

Question c)

Notice that the base here is 1/100

and that the square root of 1 is 1 and that of 100 is 10.

Therefore, the given

{1/100} is equivalent to {1/10)^2

and so we have:

          1                      1

  (------------)^(1/x) = -------   (we are to find x)

     10^2                    10

Note that 10 is the square root of 10^2, also the square root of 100.

So let's take the square root of 10^2.  We get 10.

Therefore, try x = 2 and see whether the given equation is true:

      1                      1

{---------)^(1/2)   =  ------

 100                     10

The square root of 1 is just 1.  The square root of 100 is 10.  

Therefore the above equation becomes

 1        1

----- = -----  and so  x = 2 is correct.

Answer:

2 ; $9.94

Step-by-step explanation:

Given that:

Balloons chosen : 6 and 50

Greatest possible number of bouquet that can be made using all balloons

To find this ; obtain the greatest common factor of 6 and 50

Factors of 6 : 1, 2, 3, 6

Factors of 50 : 1, 2, 5, 10, 25, 50

.the greatest factor common in both is 2.

Greatest possible number of bouquet using all balloons = 2

If each bouquet sells for $4.97

Earning = 2 * $4.97

Earning = $9.94

Answer:

Step-by-step explanation:

The signs of the terms are + - - +. There are two sign changes, so 0 or 2 positive real roots.

Negating the signs of the odd-degree terms, the signs are + + + +. There are no sign changes, so 0 negative real roots.

For x=0, the value of the quartic is +3. For x=1, the value is -3, so we know there are 2 positive real roots, one of which lies in the interval (0, 1).

The 4th-degree polynomial equation must have 4 roots, so the other two must be complex.

Answer: The perimeter is doubled

Step-by-step explanation:

When you double the length and width you have 2l as length and 2w as width. The new perimeter is 2(2l)+2(2w)=2(2l+2w). This means that when you double both sides, the perimeter is doubled.
