To find the best estimate of the number of students who are liberal arts majors, we could do the following:

Since we know that 48 out of 64 students are liberal arts majors and there are 7693 students, then:

Therefore, 5770 students are liberal arts majors.

The number of students who are liberal arts majors is 5770.

There are 48 students out of 64 students are liberal arts majors.

This means:-

           (48/64) × 100 = 75%

75% of total students are liberal arts majors.

Therefore,

The number of students in liberal arts majors = (75/100) × 7693

The number of students in liberal arts majors = 5769.75 ≈ 5770

System Linear equation has no solution , because it is paralell lines but no intersection.

What is system linear equation?

An equation for a line is known as a linear equation. alternatively, y + 0.5x 3.5 = 0 and others. (Note that each linear equation is the same.) When multiple linear equations interact, we get a system of linear equations.

Here the given system linear equations,

\(3y=\frac{3}{2}x+6\) -------> 1    and \(\frac{1}{2}y-\frac{1}{4}x=3\) --------> 2

Divide by 3  of equation 1 on both sides then,

\(y=\frac{1}{2}x+2\)  -----------> 3

Now put 3 into 2 then,

=> \(\frac{1}{4}x+1-\frac{1}{4}x=3\)

=> 1=3

Hence the given system equation has no solution , because it is paralell lines but no intersection.

Answer: BC = 24

Step-by-step explanation:

Given:

AB = x+33

AC = 3x - 15

BC = x

<B = <C

Solution:

Because <B = <C, you can say the corresponding sides AB and AC are equal as well

AB = AC

The y intercept is when the coordinate has the component of x equal to 0 and the x intercept is when y = 0 s

The equation that represents this relationship is h*n = 24.

How do we solve linear equations?
First order equations include all linear equations as a subset. In the coordinate system, lines are defined as having linear equations. A linear equation in one variable is made up of one homogeneous variable of degree one (i.e., only one variable). A linear equation could contain multiple variables. When a linear equation comprises two variables, for instance, linear equations in two variables are utilized. A mathematical statement known as an equation contains an algebraic expression and the equal symbol (=). It is the equation for a straight line. The equation is shown to be valid when values are substituted for the unknown values in the solutions of linear equations. When there is just one variable, there is just one answer.

Given, number of hours needed to paint a house = h
Number of painters needed to paint the house = n
Also, the relation between h and n is inverse, thus:
h*n = k, where k is the proportionality constant.
Therefore, initial equation derived is h*n = k --(i)
Putting h = 6 and n =4 in (i), we can get the value of k as
k = h*n = 6*4 = 24 --(ii)
Comparing (i) and (ii), we get,
h*n = 24, which is the required equation.

The inequality corresponding to the equation -4x + y = -3 is either y > 4x - 3 or y < 4x - 3, depending on the relationship between 4x - 3 and 0.

To write the inequality represented by the equation -4x + y = -3, we first need to manipulate the equation to express y in terms of x.

Starting with -4x + y = -3, we isolate y by adding 4x to both sides:

y = 4x - 3

Now we have y expressed in terms of x. To form the inequality, we consider the relationship between x and y. The inequality depends on whether the expression 4x - 3 is greater than or less than 0.

If 4x - 3 is greater than 0, then y is greater than 0, and we can write the inequality as:

y > 4x - 3

If 4x - 3 is less than 0, then y is less than 0, and we can write the inequality as:

y < 4x - 3

The inequality represents a region in the coordinate plane where the y-values are either greater than or less than the expression 4x - 3, depending on the direction of the inequality sign.

For example, if we choose a point (x, y) in the region above the line y = 4x - 3, where y is greater than 4x - 3, the inequality y > 4x - 3 will hold true. On the other hand, if we choose a point below the line, where y is less than 4x - 3, the inequality y < 4x - 3 will be satisfied.

We have shown that the path of a moving point with velocities u + ey and v + ex, parallel to the axes of x and y, is either a line (when v - \(e^2\) ≠ 0) or a horizontal line (when v - \(e^2\) = 0), both of which are conic sections.

To show that the path of a moving point parallel to the axes of x and y with velocities u + ey and v + ex is a conic section, we can analyze the motion of the point using the principles of calculus and conic sections.

Let's denote the position of the point at any given time t as (x, y). We are given that the velocities along the x and y axes are u + ey and v + ex, respectively. This means that the derivatives of x and y with respect to time, dx/dt and dy/dt, can be expressed as:

dx/dt = u + ey

dy/dt = v + ex

Now, let's integrate these expressions to obtain x and y as functions of t. Integrating dx/dt with respect to t gives:

x = ut + eyt + C1

Similarly, integrating dy/dt with respect to t gives:

y = vt + ext + C2

Where C1 and C2 are constants of integration.

Now, we can eliminate the parameter t by expressing t in terms of x and y. From the equation y = vt + ext + C2, we can solve for t:

t = (y - ext - C2) / v

Substituting this value of t into the equation for x, we get:

x = u[(y - ext - C2) / v] + ey[(y - ext - C2) / v] + C1

Simplifying this equation, we obtain:

vx - u - evx + ue + vy - \(e^2\)x - eyC2 = C1v

Rearranging the terms, we get:

vx - vy + ue + evx - \(e^2\)x = C1v + eyC2 - u

Let's define new constants A = ue + ev and B = C1v + eyC2 - u. The equation then becomes:

(v - \(e^2\))x + (u + ev)y = A + B

This equation is in the standard form of a conic section, specifically a line. However, we can manipulate this equation further to reveal other possible conic sections.

Let's consider the case when v - \(e^2\) ≠ 0. In this case, we can divide both sides of the equation by v - \(e^2\), yielding:

x + [(u + ev)/(v - \(e^2\))]y = (A + B)/(v - \(e^2\))

Now, let's define another constant C = (u + ev)/(v -\(e^2\)) and rewrite the equation as:

x + Cy = D

Where D = (A + B)/(v - \(e^2\)).

This equation represents a line in the x-y plane.

On the other hand, if v - \(e^2\) = 0, the equation becomes:

0x + (u + ev)y = A + B

This simplifies to:

(u + ev)y = A + B

Which is a horizontal line parallel to the x-axis.

Therefore, we have shown that the path of a moving point with velocities u + ey and v + ex, parallel to the axes of x and y, is either a line (when v - \(e^2\) ≠ 0) or a horizontal line (when v - \(e^2\) = 0), both of which are conic sections.

The answer before and after combining the like terms is 32.

How to evaluate the expression using the value of the variable given

Given: 5x+3x; x=4

To evaluate the expression before combining like terms. We substitute x = 4 into the expression the way it is:

5x + 3x = 5(4) + 3(4)

            = 20 + 12 = 32

To evaluate the expression by combining like terms. We will add the like terms and then put x = 4 afterward:

5x + 3x = 8x

Put x = 4:   8x = 8(4) = 32

Since the expression evaluates to 32 before and after combining the like terms. Therefore, the results before and after the combination are the same.

The percent of the total calories in each brownie that comes from fat is 26.9%

We know that the total amount of calories in each brownie is 420 calories, so that number represents our 100%, then we can write the relation:

420 cal = 100%

Now, the fat has 113 calories, this is a percentage X that we want to find, so we can write:

113 cal = X

We have the two relations:

113 cal = X

420 cal = 100%

If we take the quotient we get:

(113 cal/420 cal) = X/100%

Solving for X.

(113 cal/420 cal)*100% = X = 26.9%

So, the percent of the total calories in each brownie that comes from fat is 26.9%.

Answer:

We conclude that all the pairs of points have positive slopes.

Thus, there is NO pair of points that has a negative slope.

Step-by-step explanation:

a)

Determining the slope between (-10, -3), (-7, 6)

\(\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\)

\(\left(x_1,\:y_1\right)=\left(-10,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-7,\:6\right)\)

\(m=\frac{6-\left(-3\right)}{-7-\left(-10\right)}\)

\(m=3\)

b)

Determining the slope between (7, 7), (-8, 1)

\(\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\)

\(m=\frac{1-7}{-8-7}\)

\(m=\frac{2}{5}\)

c)

Determining the slope between (5,2), (-9,-10)

\(\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\)

\(m=\frac{-10-2}{-9-5}\)

\(m=\frac{6}{7}\)

d)

Determining the slope between  (2,9), (-3,-1)

\(\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\)

\(m=\frac{-1-9}{-3-2}\)

\(m=2\)
