The number of phones sold would be 20

And, the number of accessories sold would be 26.

Used the concept of an equation that states,

An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.

Given that,

Kylie earns a $15 commission for every phone she sells and a $2 commission for every accessory she sells.

And, On a given day, Kylie made a total of $352 in commission and sold 6 more accessories than phones.

Let us assume that,

The number of phones sold = x

And, the number of accessories sold = y

Hence, the equation becomes,

15x + 2y = 352   .. (i)

And, y = x + 6  .. (ii)

Substitute the value of y in (i);

15x + 2y = 352  

15x + 2 (x + 6) = 352

15x + 2x + 12 = 352

17x + 12 = 352

17x = 352 - 12

17x = 340

x = 340/17

x = 20

From (ii);

y = x + 6

y = 20 + 6

y = 26

Therefore,  The number of phones sold = 20

And, the number of accessories sold = 26

Answer: slope = 0

Step-by-step explanation:

The equation of straight line can be expressed in the form y = mx + b, which is referred to as slope intercept form.

In this equation, m represents the slope of the line, y is the y-coordinate of an arbitrary point along the line and x is the x-coordinate of the same point, and b is the location where the line intercepts the y-axis of the graph.

if y = 16, then the slope of the line, m, must be 0.

y = mx + b

y = (0)x + b

y = b

In other words, the line described by the equation y = 16 is a horizontal line that passes through the y-axis at the point (0,16).

The constant of variation of the distance is 13.5 miles

From the question, we have the following parameters that can be used in our solution:

Distance cycled = 9 miles

Number of hours = 2/3 of an hour

From the above parameter, we can calculate the constant of variation

The constant of variation is calculated as

Constant of variation = Distance cycled/Number of hours

Substitute the known values in the above equation

So, we have the following equation

Constant of variation = 9/(2/3)

Evaluate the quotient

Constant of variation = 13.5

Hence, the constant of variation is 13.5 miles per hour

The measure of angle KJL from the given figure is 84°.

Given that, 3(m∠LJM)=2(m∠KJL) and m∠KJM=140°.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Here, m∠KJM=m∠LJM+m∠KJL

Now, (m∠LJM)=2/3 (m∠KJL)

140°= 2/3 (m∠KJL) + m∠KJL

⇒ [2(m∠KJL)+3(m∠KJL)]/3 = 140°

⇒ 5m∠KJL=420°

⇒ m∠KJL=420°/5

⇒ m∠KJL=84°

y = [tex]\frac{3}{2}[/tex] x + 3

Slope: [tex]\frac{3}{2}[/tex]

y-intercept: 3

Answer:

In the equation of a straight line (when the equation is written as "y = MX + b"), the slope is the number "m" that is multiplied by the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Answer: The equation defines the relationship between the angle of inclination of the line relative to the x-axis and the point at which the line passes through the y-axis on a graph.

Step-by-step explanation:

Imagine a line, L, that passes through the y-axis of a graph at some point B=(0,b), where the 0 is the x-coordinate of B and b is the y-coordinate of B. In this case, we will use the variable m to represent the slope of the line. Geometrically, the slope of a line is said to be tangent to its angle of inclination, the smaller of the two angles formed by the line L and the x-axis. In trigonometry, the tangent of an angle in a right triangle is defined as the ratio of the side opposite of it over the side adjacent to it. This relationship can be illustrated by constructing a right triangle where the hypotenuse is formed by the segment of the line L between the point B and an arbitrary point P somewhere along the line with the coordinates (x,y).

This triangle can be seen in the attached jpg. The side opposite of the angle of inclination is the imaginary vertical line formed between the point P and the x axis and the side adjacent to it is formed by the imaginary horizontal line between the point B and the vertical line from P. The point where these imaginary lines intersect forms the right angle of the triangle. The length of the opposite side, l1, can be expressed as the difference in y between points P and B:

l1 = y-b

Likewise, the length of the adjacent side, l2, can be expressed as the difference in x between points P and B:

l2 = x-0

The tangent of the angle of inclination, labled as [tex]\alpha[/tex] in the picture, can then be expressed as:

tan([tex]\alpha[/tex]) = [tex]\frac{(y-b)}{(x-0)}[/tex]

simplified as:

tan([tex]\alpha[/tex]) = [tex]\frac{y-b}{x}[/tex]

Because we know that slope m = tan([tex]\alpha[/tex]), we can say that

m =  [tex]\frac{y-b}{x}[/tex]

solving by algebra for y,

mx + b = y              or             y = mx + b

in single variable calculus, the slope of a line is described as the rate of change of its y coordinates with respect to the rate of change of its x coordinates, referred to as the derivative of y with respect to x. This relationship is used to describe things like the speed of an object as it relates to the change in the objects position. The important thing to realize here is the connection between the slope, which we expressed as the difference in the y values of two points on a line over the difference in their x values, and the behavior of the coordinates of points as you move along the line.

Hope that helps! If the last bit is confusing, don't worry, as long as you understand why y=mx+b is the slope intercept form you've got the right idea.

If a chemist wants to make 671 milliliters of the drug, then 305 milliliters of compound A are needed.

Given that:

A certain drug is made of compound A and compound B.

There are 5 milliliters of compound A used for every 6 milliliters of compound B.

So, A and B are in the ratio of 5:6.

Let a chemist will use 5x milliliters of compound A and 6x milliliters of compound B to make 671 milliliters of the drug.

So, we equate the total amount and find the value of x.

i.e. 5x + 6x = 671

=> 11x = 671

=> x = 61

Putting the value of x = 61. We get the value of compound A and compound B.

The value of compound A = 5x = 5 x 61 = 305 milliliters.

The value of compound B = 6x = 6 x 61 = 366 milliliters.

Isosceles triangle, in geometry, refers to a triangle that has at least two equal length sides. The isosceles triangle sometimes is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length. The triangle which has at least two sides of equal length includes the equilateral triangle as a special case. An isosceles triangle has two sides that are congruent to each other and the third side which is unequal to the other two sides is called the base of the isosceles triangle. The two angles opposite to the equal sides are congruent to each other.
