Let the price of black and white brouchers be x

The price of color brochures be y.

A/q,

4x+4y=148.....(1)

4x+3y=125 .....(2)

The equation (1) becomes,

x+y=37

y=37-x.......(3)

Putting (3) in (2) we have,

4x+3(37-x)=125

4x+111-3x=125

x=14

Putting the value of x in (3) we have,

y=37-14=23

The price of black and white brouches is $14

The price of color brouchers is $23.

After 10 years, the money dis she earn is $800 with the interest of 6%.

Interest:

Interest is the amount for a particular principal amount of money at some rate of interest.

Given,

Jackie deposited $500 in an account for 10 years at 6% interest.

Here we need to find the money did she earned.

We know that, the interest for the amount is 6%.

So, the amount after 10 years is,

=> 500 x (6/100) x 10

=> 30 x 10

=> 300

Therefore, the interest amount is 300.

So, the total amount she will receive after 10 years is,

=> 500 + 300

=> 800

Therefore, she will earn $800 after 10 years.

When there are two middle values, the median is the mean of these two values:

Answer:

x is any real number from -infinity to infinity.

The equation for the quadratic graphed as x-intercepts: (-3,0) and (-1,0); y-intercept: (0,-2) can be written as y = -1/2 (x+3)(x+1)

An equation of the second degree, or one with at least one squared term, is a quadratic equation. The equation in standard form is written as ax2 + bx + c = 0, where a, b, and c are numerical coefficients that are constants, and x is an unknown variable.

The initial constant, “a,” cannot be 0, and this is an unbreakable rule.

In order to put the equation in y-intercept (y=mx+b) form and determine the equation of a graphed line, first determine the slope and y-intercept. The slope is the ratio of the y-to-x change.

Thereafter draw a sloping triangle connecting the two spots you find on the line.

If the x intercepts are -3 and -1, then the factored form is y = a(x + 3)(x + 1). In order to find "a", we plug in the data point (x, y) of (0, -2) so:

-2 = a(0+3)(0+1)

-2 = 4a

a = -1/2

So the equation can be written as y = -1/2 (x+3)(x+1)

Step-by-step explanation:

Matching the given mathematical operation equations to the specified choices, gives;

A•B = B•A ; Commutative Property of Multiplication

A + B = B + A ; Commutative Property of Addition

(A•B)•C = A•(B•C); Associative Property of Multiplication

A•0 = 0; Multiplicative Property of 0

(A + B) + C = A + (B + C); Associative Property of Addition

A•1 = A; Multiplicative Identity

A + 0 = A; Additive Identity

The properties of mathematical operations includes; inverse, associative, distributive, associative and commutative properties

Commutative property in mathematics is one in which for a binary operation, the result of an operation remains unchanged when the order in which the operands appears in the expression is changed.

Therefore;

Commutative property of multiplication is therefore; A•B = B•A

Commutative property of addition is; A+B = B+A

Associative property relates with operations that have results which remains the same when the parentheses in the expressions are rearranged.

Therefore;

(A•B)•C = A•(B•C) represents the associative property of multiplication

The associative property of addition is represented by (A+B)+C = A+(B+C)

The multiplicative property of 0, which can be understood as the zero product property, states that the product of any number and 0 is 0

Therefore, the equation, A•0 = 0, represents the multiplicative property of 0

The multiplicative and additive identity states that an expression remains the same following the product of the expression with an identity element such as 1, or following the addition of the expression with an identity element such as 0

The multiplicative and additive identity are therefore represented by A•1 = A and A + 0 = A respectively

Based on the slope formula for a line, the value of a is: a = -3.

If two points on a line have the following coordinates, (x1, y1) and (x2, y2), to find the slope (m) of the line, the formula that is applied is given as:

Slope (m) = change in y /change in x = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = rise/run.

The given line has the following:

(-10, 0) = (x1, y1)

(a, -6) = (x2, y2)

Slope (m) of the line = -6/7.

Plug in the values into the slope formula for a line:

(-6 - 0) / (a - (-10)) = -6/7

-6/(a + 10) = -6/7

Cross multiply and solve to find the value of a in the equation:

-6(a + 10) = -6(7)

Apply the distributive property

-6a - 60 = -42

Add 60 to both sides

-6a - 60 + 60 = -42 + 60 [addition property of equality]

-6a = 18

Divide both sides by -6

-6a/-6 = 18/-6 [division property of equality]

a = -3

Therefore, the value of a is -3.

The line that has a slope of -6/7 will have the following points, (-10, 0) and (-3, -6).

Using the law of Sines, the length of side AD, |AD|, is 7.44

From the question, we are to determine the length of side AD

From the given information, we have that

u = 17 and v = 17

Then,

ΔBCD is an isosceles triangle

∴ m ∠DBC = m ∠ BCD

m ∠DBC = x = 25°

∴ m ∠BCD = 25°

Also,

m ∠BCA = ∠y + m ∠BCD

m ∠BCA = 25° + 25°

m ∠BCA = 50°

Now, we will determine the measure of ∠CAD.

m ∠CAD + m ∠DBC + m ∠BCA = 180° (Sum of angles in a triangle)

m ∠CAD + 25° + 50° = 180°

m ∠CAD = 180° - 25° - 50°

m ∠CAD = 105°

Now,

From law of Sines, we can write that

|AD| / sin DCA = |DC| / sin CAD

|AD| / sin y = u / sin CAD

|AD| / sin 25° = 17 / sin 105°

|AD| = (17 × sin 25°) / sin 105°

|AD| = 7.43795

|AD| ≈ 7.44

By graphing both equations and finding where the graphs intercept, we can see that the solution for the system is x = 3.

Here we have the functions:

f(x) = -2x +4

g(x) = 2x - 8

We want to find the value of x such that:

If we graph the two functions, we just need to identify the x-value of the point where the functions intercept.

The graph can be seen in the image below.

There we can see that the graphs intercept at (3, -2), meaning that the solution of:

f(x) = g(x) is x = 3.
