Answer:

Therefore,

x+2=13 .......Equation

Angelica's Brother's age is 11 years old.

Step-by-step explanation:

Given:

Let the current age of Angelica's Brother be 'x' years old

Angelica's current age is 13 years old,

According to given condition,

Therefore the Equation will be,

x+2=13

On solving this equation we get

x=13-2=11\\\\x=11\ years

Therefore,

Angelica's Brother's age is 11 years old.

Therefore,

x+2=13 .......Equation

Angelica's Brother's age is 11 years old.

Suppose that the functions s and t are defined for all real numbers x as follows.
jeka94

Answer:

(s.t)(x) = 4x^2+24x^2\\(s-t)(x) = x+6-4x^2\\(s+t)(-3) = 39

Step-by-step explanation:

Given functions are:

s(x)= x+6\\t(x)= 4x^2

We have to find:

(s.t)(x) => this means we have to multiply the two functions to get the result.

So,

(s.t)(x) = s(x)*t(x)\\= (x+6)(4x^2)\\=4x^2.x+4x^2.6\\=4x^3+24x^2

Also we have to find

(s-t)(x) => we have to subtract function t from function s

(s-t)(x) = s(x) - t(x)\\= (x+6) - (4x^2)\\=x+6-4x^2

Also we have to find,

(s+t)(-3) => first we have to find sum of both functions and then put -3 in place of x

(s+t)(x) = s(x)+t(x)\\= x+6+4x^2

Putting x = -3

= -3+6+4(-3)^2\\=-3+6+4(9)\\=3+36\\=39

Hence,

(s.t)(x) = 4x^2+24x^2\\(s-t)(x) = x+6-4x^2\\(s+t)(-3) = 39

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The membe
Rzqust [24]

Answer:

The equation that represents the relationship between the number of T-shirts ordered, the number of colors on the shirts, and the total cost of the order  is Y = $225 +  X × $50

Where;

Y = The total cost of the order

X = The number of colors on the shirts

Step-by-step explanation:

The number of T-shirts required by the members of the school choir = 75

The amount charged by the printing company per shirt = $3

The charge for each color to be printed on the shirts = $50

The number of T-shirts ordered = 75

The charge per shirt = $3

The number of colors on the shirts = X

The fee per color on the shirts = $50

The total cost of the order = Y

Therefore, we have;

The basic cost of printing the 75 shirts = The charge per shirt × The number of T-shirts ordered

∴ The basic cost of printing the 75 shirts = $3 × 75 = $225

The total fee of the added colors to the shirt = The number of colors on the shirts × The fee per color on the shirts

∴ The total fee of the added colors to the shirt = X × $50

The total cost of the order, Y = The basic cost of printing the 75 shirts + The total fee of the added colors to the shirt

∴ Y = $225 +  X × $50

The equation is therefore;

Y = $225 +  X × $50.
