Answer:

[tex]x=\frac{e^7-3}{7}[/tex]

Step-by-step explanation:

4* ln(7x+3) + 12 = 40

4* ln(7x+3) + 12 - 12 = 40 - 12

4* ln(7x+3) = 28

ln(7x+3) = 28/4

ln(7x+3) = 7

e^7 = (7x + 3)

e^7 - 3 = 7x

[tex]x=\frac{e^7-3}{7}[/tex]

(C) 6+4+10/15+3/15

Step-by-step explanation:

2/3=10/15

1/5=3/15

6+4+13/15

10 13/15

Answer: a) (3,0.5) b)(28/13, 47/13)

1)7x+4y=23

8x-10y=19

70x+40y=230

32x-40y=76

102x=306

x=306/102=3

7(3)+4y=23

21+4y=23

4y=2

y=1/2

2)Step-by-step explanation:

11x-6y=2

-8x+5y=3

Multiply the first equation by 5 and the second by 6.

55x-30y=10

-42x+30y=18

Now add both of the new equations

13x=28

x=28/13

Now plug it into the first equation to find y

11(28/13)-6y=2

308/13-6y=2

y=47/13

Answer:

S18 = 288

Step-by-step explanation:

find the first and last term.

n = 1

a1 = 2 x 1 - 3

a18 = 2 x 18 - 3

(simplify the expression)

a1 = -1

a18 = 33

(use the formula for the sum of a finite arithmetic series)

                     a1 + a18

S18 = 18 x ---------------------

                           2

(use the substitute) substitute -1 for a1 and 33 for a18

                       -1 + 33

S18 = 18 x ---------------------

                             2

Answer:

6 x 25 = 150-40=110

Step-by-step explanation:

It's right I promise you

The value of x in the given quadratic equation is determined as -7 ± 8i.

The solutiion to the linear equation is determined as follows;

x² + 14x + 17 = -96

x² + 14x + 17 + 96 = 0

x² + 14x + 113 = 0

solve the equation using formula method;

a = 1, b = 14, c = 113

[tex]x = \frac{-b \ \ \pm\sqrt{b^2 - 4ac} }{2a} \\\\x = \frac{- 14\ \ \pm\sqrt{(14)^2 - 4(1\times 113)} }{2(1)} \\\\x = \frac{- 14\ \ \pm\sqrt{-256} }{2}\\\\x = \frac{- 14\ \ \pm\sqrt{256} \times \sqrt{-1} }{2}\\\\x = \frac{-14 \ \ \pm 16 \times i}{2} \\\\x = -7 \pm 8i[/tex]

Thus, the value of x in the given quadratic equation is determined as -7 ± 8i.

The expression that is equivalent to [3/(x + 1)] ÷ 1/(x + 1)] after simplification is gotten as; 3

We want to simplify the expression;

[3/(x + 1)] ÷ 1/(x + 1)]

This fraction expression will be re-expressed as;

[3/(x + 1)] * (x + 1)/1

x + 1 will cancel out to give us the expression as;

[3/(x + 1)] * (x + 1)/1 = 3

Answer:

Unrational

Step-by-step explanation:

Step 1:  Determine what is rational and unrational

"A rational number includes any whole number, fraction, or decimal that ends or repeats. An irrational number is any number that cannot be turned into a fraction, so any number that does not fit the definition of a rational number."

Step 2:  Now determine what our number fits into

Since our decimal isn't a whole number, isn't a fraction, and it is a decimal that continues to either repeat or just continues.  Therefore, our number would fit into the unrational category.  If our number is just 2.67034165508 then it would be a rational number since it ends.  However, since we have the ... at the end that means that it continues and therefore falls into the unrational category.

2x - y = 3

3x = 9

3x/3 = 9/3

x = 3

x + y = 6

y = 6 -x
