Does anybody know the answer to this question please I need help?!

Answer:

40 years

Step-by-step explanation:

Hulian and Thomas together is 65 years

let us suppose hulian is X

now, so Thomas is x+15

so x+x+15=65

so 2x = 65-15

2x=50

x=25

Hulian is 25

and Thomas is 25+15=40

Answer:

Thomas's age: 40

Step-by-step explanation:

We have:

Thomas's age - Huilan's age = 15 (1)

Thomas's age + Huilan's age = 65 (2)

Add 1 and 2 we have :

2T = 65+15

<=>2T = 80

[tex]<=>T=\frac{80}{2} =40[/tex]

So Thomas's age is 40.

P/s: T is Thomas's age

Answer:

f(g(3)) = 3

Step-by-step explanation:

We are told to solve for f(g(3)). This is also saying f of g of 3.

To find f(g(3)), we need to plug 3 in for x in g(x), since it says g(3).

g(x) = 3(3) - 4

Solve.

= 9 - 4

g(x) = 5

Now, we plug that into f(x), because g(x) was placed inside f and replaces the x variable of f(x).

f(5) = 2(5) - 7

Solve.

= 10 - 7

f(5) = 3.

f(g(3)) = 3

Answer:

[tex]y=(x-3)^2-6[/tex]

Step-by-step explanation:

[tex]y=x^2-6x+3[/tex]

This is written in the standard form of a quadratic function:

[tex]y=ax^2+bx+c[/tex]

where:

You need to convert this to vertex form:

[tex]y=a(x-h)^2+k[/tex]

where:

To find the vertex form, you need to find the vertex. For this, use the equation for axis of symmetry, since this line passes through the vertex:

[tex]x=-\frac{b}{2a}[/tex]

Using your original equation, identify the a, b, and c terms:

[tex]a=1\\\\b=-6\\\\c=3[/tex]

Insert the known values into the equation:

[tex]x=-\frac{(-6)}{2(1)}[/tex]

Simplify. Two negatives make a positive:

[tex]x=\frac{6}{2} =3[/tex]

X is equal to 3 (3,y). Insert the value of x into the standard form equation and solve for y:

[tex]y=3^2-6(3)+3[/tex]

Simplify using PEMDAS:

[tex]y=9-18+3\\\\y=-9+3\\\\y=-6[/tex]

The value of y is -6 (3,-6). Insert these values into the vertex form:

[tex](3_{h},-6_{k})\\\\y=a(x-3)^2+(-6)[/tex]

Insert the value of a and simplify:

[tex]y=(x-3)^2-6[/tex]

Answer:

Figure R'S'T'U' is the image of the figure RSTU after a translation 2 units left and 2 units down, and a reflection across the y-axis.

Step-by-step explanation:

Transformations

The figure RSTU has been transformed in such a way that it mapped onto the figure R'S'T'U'.

There has been a translation and a reflection. Since the figure and its reflection are above the x-axis, one can guess the reflection is over the y-axis.

Let's reflect point T'(-3,4) over the y-axis. It maps to (3,4). The horizontal distance from this point to the original point T(5,6) is 2 and the vertical distance is 2. Thus, under this assumption, the transformations could be: translate 2 units down, 2 units left, and reflect across the y-axis.

Testing the rest of the points we get the same result, thus the transformations are:

Figure R'S'T'U' is the image of the figure RSTU after a translation 2 units left and 2 units down, and a reflection across the y-axis.

Answer:

x = 5

Step-by-step explanation:

4(x-1)/8 = 2(x+2)/7

7*4(x-1) = 8*2(x+2)

28(x-1) = 16(x+2)

28*x + 28*-1 = 16*x + 16*2

28x - 28 = 16x + 32

28x - 16x = 32 + 28

12x = 60

x = 60/12

x = 5

Check:

4(5-1)/8 = 2(5+2)/7

4*4/8 = 2*7/7

16/8 = 2*1 = 2

a) [tex]C(n) = 450+0.60n[/tex] where [tex]n<=3000[/tex]

b) [tex]R(n) = 1.80n[/tex] where [tex]n<=3000[/tex]

c) [tex]P(n) = - 450 +1.20n[/tex]

Step-by-step explanation:

Sale price of chocolates = $1.80 per chocolate

Fixed cost for the Chocolate Shoppe per week = $450

Cost to produce one chocolate = $0.60

Cost to produce [tex]n[/tex] chocolates = $0.60[tex]\times n[/tex]

a) Cost function to represent the total cost for the production of [tex]n[/tex] chocolates :

[tex]C(n) = 450+0.60n[/tex] where [tex]n<=3000[/tex]

b) Revenue function to represent the revenue from the sale of [tex]n[/tex] chocolates:

[tex]R(n) = 1.80n[/tex] where [tex]n<=3000[/tex]

c) Profit function to represent Charlie's profit from selling [tex]n[/tex] chocolates:

Profit is nothing but revenue minus sales.

[tex]P(n) = R(n) - C(n) \\P(n) = 1.80n - 450 -0.60n\\P(n) = - 450 +1.20n[/tex]

Step-by-step explanation:

Given table:

     x      -1    1   3   5

     y      -2   0   2  4

Unknown:

Slope of the line  = ?

Solution:

Each x and y pair on the table lies on the line. Therefore, we can use them to find the slope;

  Slope  = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]  

 let us take;

x₁ = -1        x₂ = 3

y₁ = -2        y₂ = 2

Insert the parameters and solve;

   Slope = [tex]\frac{2 - (-2)}{3- (-1)}[/tex]   = [tex]\frac{4}{4}[/tex]   = 1

The slope of the line is 1

If you would like me to explain just ask.

30.16 = 17.56 + (-5x)  You need to get the -5x by itself so subtract 17.56 from 17.56 and subtract it from 30.16.

12.60 = -5x You need to get the x by itself now so divide -5 by -5 and 12.60 by -5.

Answer:I would add 3x on both sides because it would allow you to have a positive variable saving you time and effort.

Step-by-step explanation:7=7x-9

Answer:

Personally I always do the smallest variable in order to make it easier

Step-by-step explanation:

in this case i would add 3x to both sides because it's (-3x) smallest out of the two. so then the equation would be 7 = 7x - 9

from there you would add 9 to both sides and get 16 = 7x

then x = 2.29 (it's rounded up from 2.285...)

Using trigonometric identities, the solution to the equation[tex]cos(\frac{\pi }{2} -x) = \frac{\sqrt{3} }{2}[/tex] for all possible values of x on the interval [0, 2π].

Trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined.

[tex]cos(\frac{\pi }{2} - x) = \frac{\sqrt{3} }{2} \\\\cos(x) cos(\frac{\pi }{2}) + sin(x) sin(\frac{\pi }{2}) = \frac{\sqrt{3} }{2} \\\\cos(x) (0)+sin(x)(1) = \frac{\sqrt{3} }{2} \\\\sin(x) = \frac{\sqrt{3} }{2}\\\\x = \frac{\pi }{3} , \frac{2\pi }{3}[/tex]

Given :

To avoid a service​ fee, your checking account balance must be at least ​$400 at the end of each month.

Your current balance is ​$432.993.

You use your debit card to spend ​$119.86.

To Find :

What possible amounts can you deposit into your account by the end of the month to avoid paying the service​ fee.

Solution :

Amount left in the account :

A = $432.993 - ​$119.86

A = $313.133

Let, amount added is x.

So,

A + x ≥ 400

x + 313.133 ≥ 400

x ≥ 400 - 313.133

x ≥ 86.867

Therefore, possible amount needed is greater than or equal to $86.867 .

Hence, this is the required solution.

Answer:

546 mL of water

Step-by-step explanation:

To make lemonade Jenny combines water and lemon juice in the ratio of 6:1, by volume.

Let the amount of water is 6x and that of lemon juice is x.

ATQ,

6x+x = 637

7x = 637

x = 91

Amount of lemon juice = 91 mL

Amount of water = 6x = 6(91) = 546 mL

So, 546 mL of water she should add to make 637 mL of lemonade.
