Answer:

Step-by-step explanation:

Let the integers be x- 1, x and x +1, then:

The integers are 28, 29, 30

Answer:

Let the numbers be (x-1), x and (x+1)

According to the above problem,

[tex](x - 1) + x + (x + 1) = 87 \\ 3x = 87 \\ \boxed{x = 29}[/tex]

Therefore, the numbers are 28, 29 and 30.

Answer:

Step-by-step explanation:

Point-slope form is ...

  y -y1 = m(x -x1) . . . . . . line with slope m through point (x1, y1)

The given point is (6, -1), so ...

  x1 = 6

  y1 = -1

The given slope is 2, so ...

  m = 2

Substituting these into the point-slope form above gives ...

  y -(-1) = 2(x -6)

  y +1 = 2(x -6)

Answer:

y+1= 2(x-6)

Step-by-step explanation:

Hi! Before we begin answering the question, we need to recall the formula for Point-Slope Form which is y- yı= m(x-xi), in which m is the slope of the function. With this given information, we just need to plug in the point (6,-1) and the slope 2 into the given function.

This will look like:

y- (-1) = 2 (x-6)

Notice that two negatives will make a positive, so the left side of the equation is the same as y+1.

Therefore, our answer is y+1= 2(x-6) .

Answer:

81 * 4 = 324.

Step-by-step explanation:

There are 81 * 4 = 324 such integers.

There are 9000 four-digit integers from 1000 to 9999. Let’s refer to the digit that occurs three times as the triplet and the digit that occurs once as the singleton.

In the first (most significant) position there are 9 possible values for the singleton, 1 through 9. In each case there are also 9 possible values for the triplet. For example if the singleton was a 1, the triplets could be anything but a 1: 1000, 1222, 1333, …, 1999. So there are 9 * 9 = 81 cases with the singleton in the first position.

A singleton in the second position can have 10 possible values, 0 through 9. If it’s a 0 there are 9 possible values for the triplet: 1011, 2022, 3033, …, 9099. If it’s anything else there are only 8 possible values for the triplet since the triplet cannot be 0: 2122, 3133, 4144, …, 9199. So there are 9 + (8 * 9) = 81 cases with the singleton in the second position.

The third and fourth positions work just like the second. So the grand total is 81 * 4 = 324.

If you plot the 9000 four-digit integers as a 100 x 90 grid of squares and color the integers with three same digits in red, an interesting pattern occurs:

(-2,0) and (-4,-2)

Step-by-step explanation:

The solution to the system of equations is where the two graphs cross

They cross at (-2,0) and (-4,-2)

Answer:

The answer is A

Step-by-step explanation:

Go through each one and just plug in the equation

ALso a easier way is just look at the graph and look at the two lines that are shown *when the blue thingy crosses the line* (My vocabulary sucks rn)

ANd there are 2 points there, identify and you should be fine

ALso for equation purposes

y=x+2

B and C dont work

Only A and C

But the second one

Only A woris so A

Answer:

Step-by-step explanation:

1.  u^2 = x^(p+q)

v^2 = x^(p-q)

Show that logx u + logx v = p

From statement 1

p + q = logx u^2 = 2 logx u   (by the laws of logs)

Similarly:

p - q = logx v^2 = 2 logx v

So 2 logx U + 2 logx v  = p+q + (p - q)

2 (logx u + logx v)  =  2p

logx u + logx v = p.

Also 2(logx u - logx v)  =  p+q - (p - q) = 2q

and logx u - logx v = q.

2.  ∛(8a^3b^3) / √(1/25 * a^4b^7)* (16√(a^4b^6))^-1/2

= 2ab / 1/5a^2b^7/2 *  (16a^2b^3)^-1/2

= 2ab / 1/5a^2b^7/2 * 1 / 4ab^3/2

= 2ab / 4/5 a^3 b^5

=  5ab / 2 a^3 b^5

= 5/(2a^2b^4).

Answer:

We get x=3 and y=21

The ordered pair will be: (3,21)

Step-by-step explanation:

We need to use the substitution method to solve the system of equations.

[tex]y = 10x-9\\y = x + 18[/tex]

For substitution method we substitute the value of x or y from one equation to other.

Let:

[tex]y = 10x-9--eq(1)\\y = x + 18--eq(2)[/tex]

Putting value of y from equation 2 into equation 1

[tex]y=10x-9\\Put\:y=x+18\\x+18=10x-9\\x-10x=-9-18\\-9x=-27\\x=\frac{-27}{-9}\\x=3[/tex]

So, we get value of x=3

Now, for finding value of y, We substitute the value of x

Find value of x from equation 2

[tex]y=x+18\\x=y-18[/tex]

Now, putting value of x in equation 1

[tex]y=10x-9\\Put\:x=y-18\\y=10(y-18)-9\\y=10y-180-9\\y-10y=-189\\-9y=-189\\y=\frac{-189}{-9}\\y=21[/tex]

So, we get value of y=21

So, We get x=3 and y=21

The ordered pair will be: (3,21)

Answer:

Commission= $668

Step-by-step explanation:

Giving the following information:

Commission rate= 4.25% = 0.0425

Sales= $15,725

To calculate the commission earned, we need to use the following formula:

Commission= commission rate*sales

Commission= 15,725*0.0425

Commission= 668.3125

Commission= $668

Answer:

4

Step-by-step explanation:

You can rewrite this equation like this

7-3

which equals 4

Answer:

The given coordinates of the points A and C of the right triangle ABC are (2, 5) and (-2, 3) respectively

The possible pairs of the coordinates of the point B are found as follows;

1) Draw a horizontal line from the point C to the right and a vertical line down from the point A to get the point B at (2, 3) which is the point of the perpendicular intersection of the two constructed lines above

2) Draw a vertical line from the point C upwards and a horizontal line to the left from the point A to get the point B at (-2, 5) which is the point of the  perpendicular intersection of the two newly constructed lines here

Step-by-step explanation:

Answer: yes, it is a smaller temperature, which means that is "colder"

Step-by-step explanation:

I guess that the question is:

Is -10°F colder than - 4°C?

Ok, when we have a temperature T in Celcius, the equation to transform this quantity to the Fahrenheit scale is:

T' = (T*9/5) + 32°

Replacing T by the temperature in celcius, we get:

T' = (-4°*9/5) + 32° = 24.8°F

This means that -4°C is equivalent to 24.8°F

And -10°F is a smaller value than 24.8°F (which mean that is colder)

This implies that -10°F is colder than -4°C

Then the statement is true.

Step-by-step explanation:

12,000 views = 4 hours

=> 30,000 views = 4 * (30000/12000) = 10 hours.

Hence it will take 10 hours.

Answer:

10

Step-by-step explanation:

Since we know every 4 hours the vid recieves 12,000 views, we divide 12,000 by 4 to see how many views it recieves in 1 hour. We get 3,000. So 3,000 views every hour. Divide 30,000 by 3,000, to get 10 hours.

Answer:

3a

Step-by-step explanation:

Here we have to divide like terms that means 9 by 3, a^3 by a^2 and b by b. 9 by 3= 3, a^3 by a^2=a after subtracting power 3 and 2 we get 1 and b by b are both cut like dividing 2 by 2 is cut and we get 1 which is not necessary to write as there would be no difference in ans.

Step-by-step explanation:

Yun lang po correct me if iam wrong

The Required equation for the ellipse is given by   [tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex] Option B. is correct

Ellipse is cross-section part of a cone structure when cutting it out a horizontal cross-section of a cone.

(x-h)^2/a^2 + (x-k)^2/b^2 = 1
(h,k) = centre of the ellipse.
a, b = semi minor or major axis,

[tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex]

thus, the required equation of ellipse is given by [tex]\frac{(x-4)^2}{49}+\frac{y+1}{100} = 1[/tex].
