Answer:

x=\(\frac{y}{m} -\frac{p}{m} +q\)

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

We must determine the y-intercept, b using the slope and point provided.

\(-5 = -3(2) + b\\\\-5 = -6 + b\\\\1 = b\)

Now that we know the y-intercept, b, we can create the equation of this line: y = -3x + 1.

Answer: $66.7

Step-by-step explanation:

$58 spent on dinner

Gives 15% of the bill as tip

15% of 58 = 8.7

$58 + $8.7 = $66.7

The repeating decimal 2.616161... can be expressed as a fraction p/q where p and q are integers and q≠0.

To convert this repeating decimal to a fraction, we can use the following method:

Let x = 2.616161...

Then, 100x = 261.6161...

Subtracting the two equations, we get:

99x = 259

x = 259/99

Therefore, 2.616161... can be expressed as the fraction 259/99.

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

To get this answer, we'll use the cosine ratio

cos(angle) = adjacent/hypotenuse

cos(A) = AC/AB

cos(35) = b/c

cos(35) = b/280

280*cos(35) = b

b = 280*cos(35)

b = 229.362572400918

b = 229

To see the graph, the inequality pairs with  y≤ −2x−1  to complete the system of linear inequalities is y > -2x + 2.

Given,

In the question:

The inequality is given as:

y ≤ −2x−1

Now, According to the question:

The upper part of the graph must be an inequality that doesn't include the actual boundary line because such is represented with a dotted line instead of a solid one (so the equal sign must NOT be in the inequality).

The boundary line for the upper section has also the same slope as the one given (-2), and we also see that it goes through the value 2 on the y-axis, so such line in slope y-intercept form must be: y = -2x + 2

Since we need to include the (x, y) values on the plane that are "larger than" (y-value above) the boundary line we found, we need to select the "greater than" symbol for the inequality and :

y > -2x + 2.

Total number of boys in class are 172

A linear equation is an algebraic equation of the form y=mx+b involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

We have total  number of students in class = 410

We assume that the number of boys in class = X

We need specific subsets (denoted by "s") within the group of upper triangular real matrices (denoted by "g") to determine whether they are subgroups and normal subgroups. Additionally, if a subset is a normal subgroup, we can identify the quotient group (denoted by "g/s").

To determine if a subset "s" is a subgroup, it must satisfy two conditions: closure under matrix multiplication and inverse existence. If all matrices in "s" multiplied together yield another matrix in "s," and if the inverse of each matrix in "s" is also in "s," then "s" is a subgroup of "g."

On the other hand, to determine if a subgroup "s" is a normal subgroup, we need to check if it is invariant under conjugation. That is, for any matrix "h" in "g" and any matrix "s" in "s," the conjugate of "s" by "h" (i.e., \(hsh^(-1))\)is also in "s." If this condition holds, "s" is a normal subgroup.

If "s" is indeed a normal subgroup, the quotient group "g/s" is formed by taking the left cosets of "s" in "g." Each coset represents a distinct equivalence class of matrices in "g" that differ by an element of "s." The quotient group "g/s" can be used to study the structure and properties of the group "g" after factoring out the normal subgroup "s."

Answer:

x = 13

Step-by-step explanation:

Given: f ( x ) = 4.5 x 2 − 3 x + 2 To determine the critical points, we must first calculate the first derivative of the function.

Differentiate the given function with respect to x using the power rule of differentiation, d d x x n = n x n − 1.

f ′ (x) =    d        (4.5 x 2 − 3 x + 2)

        ______        

            d x  

Apply sum rule: d d x (f(x)) + g (x) = d d x f (x) + d d x g (x) } f ′ ( x) = d d x (4.5 x^2) + d d x (−3 x) + d d x (x) f ′ (x) = 9 x − 3

To determine the critical points, set f ′ (x) = 0 . 9 x − 3 = 0 9 x = 3 {∴ x = 13}

Therefore, the tangent line to f(x) is horizontal at the point x = 13

Answer:

0.46 m

Step-by-step explanation:

area of desks: 8 m by 12 m = 8 m * 12 m = 96 m^2

20% of this area is 20% * 96 m^2 = 19.2 m^2

The area of the border is 19.2 m^2.

Let the path around the desks have width x.

The area of desks plus path is a rectangle 2x + 8 by 2x + 12.

area of desks plus path = (2x + 8)(2x + 12)

= 4x^2 + 24x + 16x + 96 = 4x^2 + 40x + 96

The area of the border is the area of the rectangle that includes the border minus the rectangle that has just the desks.

area of border = (4x^2 + 40x + 96) - (96) =

= 4x^2 + 40x

Above, we have the area of border = 19.2, so we get this equation:

4x^2 + 40x = 19.2

4x^2 + 40x - 19.2 = 0

x^2 + 10x - 4.8 = 0

We now use the quadratic formula to solve the equation for x.

\( x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)

\( x = \dfrac{-10 \pm \sqrt{10^2 - 4(1)(-4.8)}{2(1)} \)

\( x = \dfrac{-10 \pm \sqrt{100 + 19.2 )}{2} \)

\( x = \dfrac{-10 \pm \sqrt{119.2 )}{2} \)

\( x = 0.46 \)  or  \( x = -10.46 \)

We discard the negative solution.

Answer: the border is 0.46 m wide.

To find the derivative of the function M(t) = 0.05025t³ - 1.127t² + 37.69t + 247.1, differentiate each term with respect to t.

M'(t) = d/dt (0.05025t³ - 1.127t² + 37.69t + 247.1)

Differentiating each term:

M'(t) = 3 x 0.05025t² - 2 x 1.127t + 37.69

M'(t) = 0.15075t² - 2.254t + 37.69

Answer:

Step-by-step explanation:

If the related function is decreasing when x < 0, it means that as x decreases (moves to the left on the x-axis), the corresponding y-values of the function decrease as well. In other words, the function is getting smaller as x becomes more negative.

Given that the zeros of the function are -2 and 2, it means that when x = -2 or x = 2, the function evaluates to zero. This means that the graph of the function intersects the x-axis at x = -2 and x = 2.

Based on this information, we can conclude that the related function starts from positive values, decreases as x moves to the left (x < 0), and intersects the x-axis at x = -2 and x = 2.
