Answer:

M = -13

Step-by-step explanation:

Divide both sides by -4−4.

m−26=3m

Subtract mm from both sides.

−26=3m−m

Simplify  3m - m  to  2m.

−26=2m

Divide both sides by 2

− 26/2=m

Simplify 26/2 to 13

-13=m

Switch sides.

m=13

Answer:

-13

Step-by-step explanation:

1. First distribute                      

2. Then get m on one side by adding 4m to both sides

3. Combine the numbers with the variable m

4. You need to get m by itself so divide both sides of the equation by -16

5. You should get m=-13

1.-4(m-26)=-4m+104  4m+4m+104=-12m

2. 104=-12m-4m

3. 104=-16m

4. 104/-13=-16/-16m

5. -13=m

[tex]Quotient = 17[/tex]

Step-by-step explanation:

Given

[tex]\frac{-1019}{-57}[/tex]

Required

Determine the quotient

[tex]\frac{-1019}{-57}[/tex]

Start by dividing the numerator and denominator by -1

[tex]\frac{1019}{57}[/tex]

The quotient is the integer division of two numbers;

[tex]\frac{1019}{57} = 17.8771929825[/tex]

Since, we only need the integer part;

[tex]Quotient = 17[/tex]

Answer:

For Cooper :

Simple interest = $315

The total amount he would have in his account = $1815

For Trinity :

Simple interest =  $324

The total amount she would have in her account = $2124

Trinity's interest is higher than Cooper's interest by $9

The total amount of money Trinity would have at the end of 3 years is higher than that of Cooper by $309

Step-by-step explanation:

Simple interest = principal x rate x time

Value = amount deposited + simple interest

For Cooper :

Simple interest = $1,500 x 0.07 x 3 = $315

The total amount he would have in his account = $1,500 + $315 = $1815

For Trinity :

Simple interest = $1800 x 0.06 x 3 = $324

The total amount she would have in her account = $1,800 + $324 = $2124

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Given that:

11th term of a geometric sequence is 32 times larger than the 6th term

The nth term of a geometric sequence is given by:

An = A*r^(n-1)

Where An = the nth term ; r = common ratio and n = term number ; A = first term

The 11th term:

A6 = A*r^(6 - 1) = Ar^5

A11 = 32A6 = 32Ar^5

A11 = Ar^(11 - 1) = Ar^10

Hence,

Ar^10 = 32Ar^5

r^(10 - 5) = 32

r^5 = 2^5

Hence, r = 2

Answer:

[tex]\Huge \boxed{x=8}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

E ———— F ———— G

EG = EF + FG

27 = (2x - 8) + (4x - 13)

Combining like terms.

27 = 6x - 21

Adding 21 to both sides.

48 = 6x

Dividing both sides by 6.

8 = x

[tex]\rule[225]{225}{2}[/tex]

The value of the variable x will be 1.

A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.

If EF = 2x - 8, FG = 4x - 13, and EG = 27.

Point F lies on the line segment EG. Then we have

EG = EF + FG

27 = 2x - 8 + 4x - 13

27 = 6x - 21

6 = 6x

x = 1

Then the value of the variable x will be 1.

Step-by-step explanation:

Assuming you are talking about a triangle, you would add 35 and 115 to get 150. Then subtract from 180.

35+115=150

180-150=30

Answer:

Square Root, Greatest Integer

Step-by-step explanation:

Functions can be symmetrical in two ways: They can be symmetrical across a line or symmetrical across a point.

In a Square root function, when reflected across the y-axis, the graph has no symmetry because -x returns a different value when plugged into the function.

For a Greatest Integer function, with [tex]\lfloor x \rfloor[/tex], if we change the value of x to -x and we floor -x, we get a different value than the original.

Answer:

[tex]\frac{5.57575757}{1}[/tex]

Step-by-step explanation:

Assuming you can't use a calculator:

5.575757... = 5 + 0.575757...

let 0.575757... = x

1) Substitute x for 0.575757...

5.575757... = 5 + x

2) Multiply both sides by 100

100(5.575757...) = 100(5+x)            

557.575757... = 500 + 100x    

3) Subtract 500 from both sides

57.575757... = 100x          

4) 57.575757... can be written as 57 + 0.575757...              

57 + 0.575757... = 100x

5) Substitute x for 0.575757...

57 + x = 100x

6) Subtract x from both sides

57 = 99x

7) divide both sides by 99

x = 57/99

8) plug in 57/99 for x in our original equation

5.575757... = 5 + (57/99)

9) simplify

5.575757... = ((5*99)/99) + (57/99)

5.575757... = (495/99) +(57/99)

5.575757... = (495+57)/99

5.575757... = 552/99

5.575757... as a fraction is 552/99

Answer:

A

Step-by-step explanation:

We are given the two functions:

[tex]\displaystyle h(x)=5+x \text{ and } k(x) = \frac{1}{x}[/tex]

And we want to find:

[tex](k\cdot h)(x)[/tex]

Recall that this is equivalent to:

[tex]\displaystye (k\cdot h)(x) = k(x) \cdot h(x)[/tex]

Substitute and simplify:

[tex]\displaystyle \begin{aligned} (k\cdot h)(x) & = \left(\frac{1}{x}\right)(5+x) \\ \\ & = \frac{5+x}{x} \end{aligned}[/tex]

In conclusion, our answer is A.

Answer:

A.  (5 + x) / x

Step-by-step explanation:

h(x) = 5 + x

k(h) = 1 / x

express the above to (k*h)(x)

(k*h)(x) = (1 / x) * (5 + x)

= 1/x (5+x)

= 1 * (5 + x)

         x

= 1 (5 + x) = 5 + x

= 5 + x

Answer:

The x-axis is closer to B.

Step-by-step explanation:

Since the ratio PB:AB = 2/7 is positive, the line divides internally. So, we use the equation for the coordinates of a point that internally divide a line.

So, x = (mx₂ + nx₁)/(m + n) and y = (my₂ + ny₁)/(m + n)

where PB/AB = 2/7 = n/m. So, n = 2 and m = 7

Also, Point A = (0,0) = (x₁, y₁) and point P = (10, -5) = (x₂, y₂).

Substituting these values into x and y, we have

x = (mx₂ + nx₁)/(m + n)

x = (7(10) + 2(0)₁)/(7 + 2)

x = (70 + 0)/9

x = 70/9

x = 7⁷/₉

y = (my₂ + ny₁)/(m + n)

y = (7(-5) + 2(0)₁)/(7 + 2)

y = (-35 + 0)/9

y = -35/9

y = -3⁸/₉

So, the x and y coordinates of B are  7⁷/₉ and  -3⁸/₉ respectively. So, point B is -3⁸/₉ units away from the x-axis and 7⁷/₉ units away from the y-axis. So the x-axis is closer to B.

Answer:

-3

Step-by-step explanation:

The number line is the straight line where all the numbers are expressed and when we represent this line we usually use intervals of the same length to express the numbers. For example, the numbers 0, 1, 2, 3, 4 would have the same distance between them since there is one integer between each of them.

The number line also has negative numbers, so the integer to the left of the zero is -1, then we have -2, -3, etc.

In this example we are told that the integer 3 is 3 units from 0 on the number line, this number is 3 units from zero to the right (positive numbers). So, as we said before, if we move 3 units from 0 but to the left we would be 3 units from 0 but on the side of negative numbers and thus, the integer that is also 3 units from zero on the number line is -3.

Answer:

D

you want to use the quadratic formula so you send the 6 over with the x² so you substact 6 on both sides and and and invisible 0x having your equation x²+0x-6 and substitute that equation into the quadratic formula

===========================================

Explanation:

x = amount (in inches) the spring is stretched

y = force applied (in pounds)

y = kx for some constant k, since x and y vary directly

---------------

Plug in the given info that x = 5 and y = 150 pair up together

Solve for k

150 = k*5

150/5 = k

k = 30

The equation goes from y = kx to y = 30x. Whatever the stretching distance (x) is, you multiply by 30 to get the force needed (y) to pull the spring.

---------------

Plug in y = 180 to solve for x

y = 30x

180 = 30x

30x = 180

x = 180/30

x = 6

The spring will be stretched 6 inches if you apply a force of 180 pounds.
