Answer:  -2 1/2

Step-by-step explanation

if the equation is + but a number is negative, remember that +- = - which means 5/12 + (-2 11/12) = 5/12 - 2 11/12

2 11/12 is bigger than 5/12, so we'll switch it around and it'll become

2 11/12 - 5/12

2 11/12 - 5/12 = 2 6/12

Because 2 11/12 is originally a negative number, +- = -

which means the answer will be negative, so it is  -2 6/12.

but we're not done yet, we need to simplify it by dividing it with 6

so the final answer is -2 1/2

if it didn't make any sense at all heres an equation version :

5/12 + (-2 11/12)

= 5/12 - 2 11/12

= 2 11/12 - 5/12

= 2 6/12 (2 11/12 is originally negative so the ans will be negative)

= - 2 6/12 (divide by 6 to simplify)

= - 2 1/2

Answer:

34.

Step-by-step explanation:

The value of 7u + 6

=3u/3 = 12/3

u = 4.

therefore u = 4

=7u + 6

=7(4) + 6

=28 + 6

=34.

The equation of the square coop is 4x = 20 and the length is 5yd .

What is equation ?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.

Refer to the images attached. Please let me know if you have any questions regarding how I did things or why.

A graph of triangle ABC after a translation of 1 unit left and 7 units down is shown in the image attached below.

In Mathematics, the translation a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image while the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.

By translating the pre-image of triangle ABC vertically down by 7 units and horizontally left by 1 unit, the coordinates of the image of triangle A'B'C' include the following:

(x, y)                               →                  (x - 1, y - 7)

Coordinate A = (-6, 7)   →    Coordinate A' (-6 - 1, 7 - 7) = (-7, 0)

Coordinate B = (-8, 1)   →    Coordinate B' = (-8 - 1, 1 - 7) = (-9, -6)

Coordinate C = (-1, 2)   →     Coordinate C' = (-1 - 1, 2 - 7) = (0, -5)

Next, we would use an online graphing calculator to construct (plot) triangle A'B'C' on a cartesian coordinate based on its vertices after a translation.

Answer: 61 cm.

Step-by-step explanation: The perimeter of any shape is the total distance of the exterior. This means that the sum of all side lengths of a shape is the perimeter. For a rectangle, the sum of both lengths and widths is the perimeter.

You can use the formula 2L+2W=P to solve this problem. 308 is P or the perimeter and 93 is L or the length. We can substitute these values and we get 2(93)+2(w)=308. We then subtract 2(93) or 186 from both sides to get 2W= 122. We then divide by two to get W or the width is equal to 61 cm.

The Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Therefore, c^2 = a^2 + b^2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

The estimated regression equation is d. ŷ = 145 + 20x₁ – 18x₂ + 4x₃

This equation is obtained from the coefficients given in the table. It is the equation that best predicts the value of the dependent variable (y) based on the values of the independent variables (x₁, x₂, and x₃).

The equation is in the form of y = β₀ + β₁x₁ + β₂x₂ + β₃x₃ + ε, where β₀, β₁, β₂, and β₃ are the coefficients of the independent variables and ε is the error term. These coefficients represent the change in the dependent variable for a unit change in the independent variable, holding all other independent variables constant.

From the table, we can see that the value of β₀ = 145, which represents the predicted value of y when all independent variables (x₁, x₂, and x₃) are equal to zero.

The value of β₁ = 20 represents the change in the predicted value of y for a unit change in x₁, holding x₂ and x₃ constant. Similarly, the value of β₂ = -18 represents the change in the predicted value of y for a unit change in x₂, holding x₁ and x₃ constant, and the value of β₃ = 4 represents the change in the predicted value of y for a unit change in x₃, holding x₁ and x₂ constant.

So, the estimated regression equation is: ŷ = 145 + 20x₁ – 18x₂ + 4x₃.

The area of the hexagon is approximate, Area = (150 √3) m².

What is a formula of a hexagon?

A Regular hexagon has six sides and angles that are congruent and is made up of six equilateral triangles. The formula to find out the area of a regular hexagon is as given:

Area = (3√3 s²)/ 2

where 's' represents the length of a side of the regular hexagon.

A hexagon is a six-sided polygon. The area of a hexagon can be calculated using the formula:

Area = (3 * √3 * (side length)^2) / 2

In this case, the hexagon is 10m by 5m, so the side length of the hexagon is 10m. Plugging this into the formula, we get:

Area = (3 * √3 * (10m)^2) / 2

Area = (3 * √3 * 100m^2) / 2

Equation of the tangent to the curve at point (-1,1) is: y=2x+3

Given,

x=cos(t)+cos(2t)

y=sin(t)+sin(2t)

P(-1,1)

For the point(-1,1), the value of t satisfy the equations x=cos(t)+cos(2t) and y=sin(t)+sin(2t) is pi/2.

To find an equation of the tangent to the curve at the given point (x,y) where x=cos(t)+cos(2t) and y=sin(t)+sin(2t) and t= pi/2, we need to first find the slope of the tangent line at this point. To do this, we need to take the derivative of the x and y functions with respect to t:

dx/dt = -sin(t) + 2sin(2t)

dy/dt = cos(t) - 2cos(2t)

Now we can use this information to find the slope of the tangent line at the given point (x,y) where x=cos(t)+cos(2t) and y=sin(t)+sin(2t) and t= pi/2:

slope = dy/dx = (cos(t) - 2cos(2t)) / (-sin(t) + 2sin(2t)) evaluated at t = pi/2

slope = (cos(pi/2) - 2cos(2pi/2))/(-sin(pi/2) + 2sin(2pi/2)) = 0 - (-2)/0 + 0 = 2

Now, we can use this slope to find the equation of tangent using:

Using the percentage method the amount of flour used this month in the bakery for bread orders is 240 kg.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

The amount of flour used last month is, a = 300 kg

The percentage of flour less used is = 20%

Calculate the 20 percent of 300 kg flour -

b = 20% × 300

b = 20/100 × 300

b = 60 kg

The amount of flour used this month = a - b

The amount of flour used this month = 300 - 60

The amount of flour used this month = 240 kg.

Yes, because it is a graph of a straight line with y = 1.625x, y changes for every value of x.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given, Value set for x and y.

Since it asked if the given equation is linear or not

The general formula for the line:

y = mx +c

where,

m is slope

and c is constant

m = (y₂ - y₁)/(x₂ - x₁)

in our case

m = 26 - 13 / 16 -8

m = 13/8

Thus the equation of a line:

y = 13/8x + c

putting any of the given coordinates in the given equation:

c = 0

Using the Addition Method to Solve Systems of Equations in Two Variables. The addition method, also known as the elimination method, is a third strategy for resolving linear equation systems. With this approach, we add two terms that share the same variable but have opposing coefficients, resulting in a sum of zero.

Consider, the given system of equations

-5x - 9y = 28             ..(1)

-4x + 5y = -2              ..(2)

Multiply equation (1) by 5 and multiply equation (2) by 9.

-25x - 45y = 140         ..(3)

-36x + 45y = -18          ..(4)

Adding equation (3) and (4), we get

     -25x - 45y = 140

+   -36x + 45y = -18

______________________

     -61x + 0  = 122

-61x = 122

   x = -2

Plug x = 2 in equation (1)

-5(-2) - 9y = 28
