Answer:

x = 3                                x = -15

Step-by-step explanation:

|2x + 12| = 18

There are two solutions to an absolute value equation, one positive and one negative

2x+12 = 18            2x+12 = -18

Subtract 12 from each side

2x+12-12 = 18-12            2x+12-12 = -18-12

2x = 6                             2x = -30

Divide by 2

2x/2 = 6/2                     2x/2 = -30/2

x = 3                                x = -15

Step-by-step explanation:

5th one = 39 + 7 = 46

6th one = 46 + 9 = 55

7th one = 55 + 11 = 66

they're increasing in odd numbers 1,3,5,7,9,11 so I added em to the numbers^^

Step-by-step explanation:

Given the function

f(x, y) = 5 + x ln(xy − 9) at the point (5, 2)

For the function to be differentiable at the given point, the differential of the function with respect to x and y must be continuous at the point.

Fx is the differential of the function with respect to x.

Using product rule to get f(x):

fx = 0 + x(1/(xy-9)y) + ln(xy-9)

fx = xy(1/(xy-9)) + ln(xy-9)

Substitute point (5, 2) into fx

fx = 5(2)(1/5(2)-9) + ln(5(2)-9)

fx = 10(1/(10-9)) + ln(10-9)

fx = 10(1/1) + ln1

fx = 10 + 0

fx = 10

For fy:

fy = 0 + x²(1/(xy-9))+ 0

fy = x²(1/(xy-9))

Substitute point (5, 2) into fy

fy = 5²(1/(5(2)-9))

fy = 25(1/10-9)

fy = 25(1/1)

fy = 25

Next is to calculate f(5,2)

f(5,2) = 5 + 5 ln(2(5) − 9)

f(5,2) = 5 + 5 ln(10− 9)

f(5,2) = 5 + 5 ln1

f(5,2) = 5 + 5(0)

f(5,2) = 5

Since fx ≠ fy, hence the function is not differentiable at the given point

Answer: The △PQR is reflected across the y-axis and option 2 is correct.

Step-by-step explanation:1. The reflection across the x-axis is defined as

2. The reflection across the y-axis is defined as

3. The reflection across the y=x is defined as

4. The reflection across the y=-x  is defined as

It is given that the vertices of ​ △PQR ​ are P(1,1) , Q(−1,−2) , and R(4,−2) . The vertices of ​ △P′Q′R′ ​ are P′(−1,1) , Q′(1,−2) , and R′(−4,−2) .

The relation between prerimage and image is defined as

Therefore the △PQR is reflected across the y-axis and option 2 is correct.

Step-by-step explanation:

Answer:

4 students is 20% of 20 students.

Step-by-step explanation:

We can say that 20 students represent 100% and that 4 students represent x% of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 %

4 students are 20 percent of 20 students.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

We can say that 20 students represent 100% and that 4 students represent x% of all students.

Thus, we can use the proportion:

20 : 4 = 100: x, or 20 / 4 = 100 / x.

cross multiply

20 x = 4 * 100

20 x = 400

x = 400: 20

x = 20 %.

therefore, we can say that 4 students are 20 percent of 20 students.

Answer:

[tex]e^{2n}x + C[/tex] (since n is assumed to be a constant when integrating with respect to x)

Step-by-step explanation:

You are integrating with respect to x, but [tex]e^{2n}[/tex] has no x-terms. Thus, it is considered a constant. The integral of any constant is equal to the constant multiplied by x.

Example: the integral of 2 is 2x, since the derivative of 2x is 2.

[tex]\int {e^{2n}} \, dx = e^{2n}x + C[/tex]

If you were integrating [tex]e^{2x}[/tex] with respect to x, it would look like this:

Since...

[tex]\frac{d}{dx} (e^{ax}) = ae^{ax}[/tex]

The integral of [tex]e^{ax}[/tex] is:

[tex]\int{e^{ax}} \, dx = \frac{e^{ax}}{a} + C[/tex]

[tex]\int {e^{2x}} \, dx = \frac{e^{2x}}{2} + C[/tex]

Note: C is a constant. It can be any number.

Note: Consider we need to find the vertices of the triangle A'B'C'

Given:

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.

Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).

To find:

The vertices of the triangle A'B'C'.

Solution:

If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then

[tex](x,y)\to (y,-x)[/tex]

Using this rule, we get

[tex]A(-3,6)\to A'(6,3)[/tex]

[tex]B(2,9)\to B'(9,-2)[/tex]

[tex]C(1,1)\to C'(1,-1)[/tex]

Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).

Answer:

-5x + 8y = -21

3x - 4y = 15

8y = 5x - 21

y = 5/8x - 21/8

3x - 4y = 15

-4y = -3x + 15

y = 3/4x - 15/4

5/8x - 21/8 = 3/4x - 15/4

-1/8x = -9/8x

x = 9

3x - 4y = 15

3(9) - 4y = 15

27 - 4y = 15

-4y = -12

y = 3

(9, 3)

Answer:

  (9, 3)

Step-by-step explanation:

My favorite way to solve equations like this is using a graphing calculator. For Desmos, one only needs to type the equations into the input column, click on one of them, and highlight the point of intersection to see the coordinates there.

__

The usual ways to solve these are by substitution or elimination. Another way they can be solved is using Cramer's rule, which provides a formula for the solution based on the coefficients.

  ax +by = c

  dx +ey = g

__

  x = (bg -ec)/(bd -ea) . . . . . . note the crossing pattern of the values in the products

  y = (cd -ga)/(bd -ea) . . . . . . the denominator is the same as above

__

Using these formulas, we get ...

  x = (8(15) -(-4)(-21))/(8(3) -(-4)(-5)) = (120 -84)/(24 -20) = 36/4 = 9

  y = (-21(3) -15(-5))/4 = (-63 +75)/4 = 12/4 = 3

The solution is (x, y) = (9, 3).

Doing the same by elimination involves the same amount of math and a lot more writing.

After t minutes, Tank A contains

6000 gal - (2 gal/min) t

while Tank B contains

8250 gal - (3 gal/min) t

The two tanks hold the same amount of water when these quantities are equal. Solve for t :

6000 gal - (2 gal/min) t = 8250 gal - (3 gal/min) t

(1 gal/min) t = 2250 gal

t = (2250 gal) / (1 gal/min) = 2250 min
