Answer:

Alexander made $825 in commission last week. If he averaged the same amount each week, he would have made $42,900 in commission in 2011.

Step-by-step explanation:

$7,500 x 0.11 = $825 (Last Week's Commission)

$825 x 52 (weeks in a year) = $42,900 (2011 Commission)

Before I solve the system, I am going to rewrite it to make it easier for me to understand it.

[tex]y=(x-3)^2+1\\y=-3x+10[/tex]

Notice that f(x) and g(x) have been changed into y. The reason is because f(x) and g(x) are the same and stand for y, but we only use f and g to distinguish between the 2 equations. We can use equal values to solve.

[tex](x-3)^2+1=-3x+10[/tex]              [exponent]

[tex]x^2-6x+9+1=-3x+10[/tex]        [add both sides by 3x]

[tex]x^2-3x+10=10[/tex]                        [subtract both sides by 10]

[tex]x^2-3x=0[/tex]                                  [factor]

[tex]x(x-3)=0[/tex]

Notice that x=0 and x-3=0. This means the solutions are x=0 and x=3.

To find the actual full solution, we have to plug those points back into the original equations.

[tex]-3(0)+10=0+10=10\\-3(3)+10=-9+10=1[/tex]

Therefore, the solutions to this system are (0,10) and (3,1).

Therefore , the solution of the given problem of expression comes out to be as a result, we can minimize the radical statement by doing the actions listed below.

To simplify a radical expression, use the Product Property.

1) Determine the radical's largest factor, which is also the index's precise power. Use that factor to rewrite the radicand as the intersection of two factors.

2) Apply the product rule to the radicals to rewrite them as the outcomes of two additional radicals.

3. Decompose the root of the ideal power.

Therefore, by taking the methods outlined above, we may simplify the radical expression.

The zeroes of the equation x² + 3x - 40 is -8 or 5.

A quadratic equation is a second-order polynomial equation in a single variable x ax²+bx+c=0. with a ≠ 0 .

It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem.

Given:

F(x) = x² + 3x - 40

Now, solving the quadratic Equation

x² + 3x - 40 = 0

x² + 8x - 5x - 40 = 0

x(x + 8) - 5(x + 8)=0

(x+8) (x-5)= 0

So, x+8 = 0 or x-5=0

x=-8 or x= 5

Hence, the zeroes are -8 and 5.

The slope of the line that goes through the points (0, 2) and (1, -1) is -3.

What is the slope of the line?

The slope of a line is a number that describes the steepness of a line and the direction it is heading. It is also known as the "rise over run" or the "rate of change" of a line. The slope of a line is typically represented by the letter "m" and is found using the formula:

slope = (y2 - y1) / (x2 - x1)

To find the slope of a line, you need two points on the line (x1, y1) and (x2, y2) and substitute their coordinates into the slope formula.

To find the slope of a line, we use the formula:

slope = (y2 - y1) / (x2 - x1)

In this case, we have two points: (0, 2) and (1, -1). To find the slope between these two points, we can substitute their coordinates into the slope formula:

slope = (-1 - 2) / (1 - 0)

slope = -3

Hence, the slope of the line that goes through the points (0, 2) and (1, -1) is -3.

The equation of the line with a slope of 2/3 passing through (-4, 1) is y = (2/3)x + 11/3

An equation is an expression relating two or more numbers and variables.

The slope - intercept form of a linear equation is:

y = mx + b

Where m is the rate of change(slope) and b is the y intercept.

The equation of a line passing through (x₁, y₁) with a slope of m is given by:

y - y₁ = m(x - x₁)

The line has a slope of 2/3 and pass through point (-4, 1). Hence:

y - 1 = (2/3)(x - (-4))

y - 1 = (2/3)(x + 4)

y = (2/3)x + 11/3

The equation of the line is y = (2/3)x + 11/3

Your answer would be A.

A system of linear inequalities represented by the graph are;

Inequality 1: y ≤ 3x - 3

Inequality 2: y ≥ ¹/₂x - 3

Inequalities that use < or > symbols are usually plotted with a dashed line that shows us that the line is not included in the region. Meanwhile, Inequalities that use ≤ or ≥ symbols are normally plotted with a solid line that shows us that the line is included in the region.

The general formula of equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Thus, the graph that rises to the right side in the first quadrant has;

Slope = (3 - 1)/(3 - 2)

Slope = 3

the y-intercept is at y = -3

Thus, equation is;

y ≤ 3x - 3

Thus, the graph that rises to the left side in the second quadrant has;

Slope = (1 - 0)/(2 - 0)

Slope = 1/2

the y-intercept is at y = 1

Thus, equation is;

y ≥ ¹/₂x - 3

Answer:

TQN

Step-by-step explanation:

Point A has coordinates (x1, y1). The x-coordinate, x1, is the horizontal distance from the origin, while the y-coordinate, y1, is the vertical distance from the origin.

Coordinates in math refer to a pair of numbers that indicate the position of a point on a two-dimensional graph or in a three-dimensional space. The two numbers are usually referred to as the x-coordinate (or abscissa) and the y-coordinate (or ordinate). In three-dimensional space, the third number is referred to as the z-coordinate (or applicate). A point located at (3, 4) on a two-dimensional graph would be located 3 units along the x-axis and 4 units along the y-axis. Similarly, a point located at (3, 4, 5) in three-dimensional space would be located 3 units along the x-axis, 4 units along the y-axis, and 5 units along the z-axis.

Both coordinates indicate the exact location of Point A in a coordinate system. For example, if Point A is located at (2, 4), it means that the x-coordinate of Point A is 2, which is 2 units away from the origin in a horizontal direction, and the y-coordinate of Point A is 4, which is 4 units away from the origin in a vertical direction. The origin is usually located at (0, 0) in a coordinate system.

Using substitution method to solve the system of linear equation, the number of children is 90 and adults is 93.

In mathematics, a system of linear equations is the collection of two or more linear equations that share the same variables. The maximum power of the variable in the linear equations in this situation is 1, making them first-order equations. A linear equation may have one, two, or three variables. We can therefore create linear equations with n variables.

To solve this problem, we have to define our variables and then write the equations.

Let;

x + y = 183 ...eq(i)

1.75x + 2.5y = 390 ...eq(ii)

solving both equations

From equation (i)

x + y = 183

x = 183 - y ...eq(iii)

Put equation (iii) into equation (ii)

1.75(183 - y) + 2.5y = 390

y = 93

Put y = 93 into equation (i)

x + 93 = 183

x = 90

The probability of selecting a student from the class who is a pet owner or prefers cats to dogs is; 0.4

In probability, If events A and B are not mutually exclusive, then the probability of A or B is expressed as;

p(A or B) = p(A) * p(B).

Total number of students = 26

Total number of students that are pet owners = 18

Total number of students that prefers cats to dogs = 26 - (8 + 3) = 15

Thus;

P(pet owner) = 18/26

P(prefers cats to dogs) = 15/26

P(Pet owner or prefers cats to dogs) = (18/26) * (15/26)
